You could feed that CO2 into a Photo Bio Reactor( PBR) and waste water( for Algea feed) to grow Algea that permanently sequesters 1 Ton of CO2 for every Barrel. Also many products can be made from Algea, Carbon Negative Algea Bio Fuel, Nutraceuticals( as Algea is rich in Omega3), Soil conditioner, Compostable Flip Flols & Surf Boards etc.
I don't know about these processes enough to really comment on them but it kinda sounds like something that would work on an industrial scale but I really don't see the average cottage with all of this equipment installed at such a small scale, kind of like the weaving industry before power looms. The issue we need be concerned with is the cost of housing services related to heat and energy. The cost of housing is growing at a rate faster than incomes for most of society, longer term this will mean that segments of the population will either find alternatives such as campers and tents, or return to the cave. The good old coal stove or boiler required only a simple man armed with a few simple tools to effect installation and repair, this now is looking like having folks with university degrees and white coats as well as a lot of expensive boxes of spare components (not parts), much like modern automotive repair, they've effectively priced the lower half of society out of owning one.

Not heard of these before I watched you talking with Skill Builder. (Oct 2023). Interesting technology. Your power generation looked like it was 24/7, so that means it's 'burning' gas 24/7. How much heating output does it produce to keep the electricity generation going? I assume it doesn't modulate generation? So it's either on at 16kwh per day or off (or cycling). Does it run 24/7 and have just enough heat output to heat up the HW cylinder twice a day? So in Summer with no CH on, is it still generating electricity 24/7? Also how does it compare to a Sterling engine gas boiler?
This is really interesting, and seems to make sense in terms of cost of power / heat etc. My worry is that for 2 kW of gas you produce 0.75 kW of electricity and 1 kW of heat... less than 90% efficient. And in terms of CO2, you are using over 40 kWh of gas to generate your 16.7 kWh of electricity each day, at a CO2 intensity of 0.183 kg/kWh (natural gas) and a grid electricity rate of 0.233 kg/kWh you would be using almost double the CO2 intensity electricity compared to electricity supplied by the national grid. And using lots of gas all year round. It is definitely an interesting piece of technology, and from what you suggest works out economically, but putting the carbon dioxide story into this.... I start to worry. Feel free to correct my understanding...!
Its a long story and we will be doing a video on it. But for every 210g/kwh this produces we have 1 less kwh being fed jn from 600g gas fores power stations. The heat output is actually 1.1kw now. So 92.5% effy

@@HeatGeek That's actually a terrible source! Firstly, the bias is clear from the start. It's a pro nuclear paper that concludes that nuclear has the best low carbon results. Secondly, it states a low, mean and higher result, but does not differentiate for CCGT or OCGT. It's clear that the lower value is for CCGT and the higher for OCGT, but they've used the mean of the studies. This ignores the simple fact that CCGT is in the case of the UK the base load generator, and OCGT only operate for approx 1hr a day, and are significantly smaller in size. And finally, that's a lifecycle analysis, not a generation analysis. You've not quoted the lifecycle analysis of the domestic system, only the operational impact.

@@HeatGeek brilliant thanks ,I put my name down for Viessmann training , really considering the heat geek courses too . The move to renewable is happening, and that unit may be one popular choice for certain properties . How much is that unit +/-, is the vat only 5% vat on that unit ?
is the hydrogen separated from the natural gas just before the boiler how is is this done some filter or catalyst what ihappens to the left over gas and what is it make u p intriguing but very cool technology
Is there a simple way to explain heat loss calculated in KW? For example heat loss of 7kw with in your property? Interested in the design aspects of heating systems as we do install some interesting stuff how ever we do not design it.
Adam I have a lot of respect for you and what you do but not once in your arguments for heat pumps do you acknowledge the fact that if we install lots of heat pumps we will have to have a lot more gas fired power stations. I would love to heat the argument for taking out gas boilers and replacing them with heat pumps. I completely agree with putting in heat pumps where you have LPG or direct electric heating but not as a substitute for gas boilers. At the moment the public are being duped.
Hi Roger Yes there is a huge task with electrification. The wind turbines currently being built and planned absolutely dwarf the current installations. There other ways to attack this issue too, for example the time of use tariffs and also storage to level peaks and troughs in demand and promote use of power only in higher times of high renewable generation. There's also decentralised units, for example the vitovalor hydrogen fuel cell in my home helps support the grid quite well, we barely draw any power. Heat pumps aren't the only solution. Just the most forward thinking. Ide love to show you the hydrogen fuel cell sometime and perhaps have a chat about heat pumps? 😁
Errr...no Roger. You are part of the duping. The UK may not be handling adoption of technology well, and you're part of that. I suggest you do some reading of the massive amounts of info published by the National Research Council of Canada on it, along with the Cdn Mortgage and Housing Corporation, and Dept of Natural Resources. Norway's domestic market is 60% heat-pump, Sweden is 43%. In Europe, out of 21 countries, the UK is tied for last as per adoption.
I think you could just add water to the co2 exhaust and make carbonic acid, from which you can get bicarbonate and hydrogen ions. Use the H⁺ ions on fuelcell and add sodium to stabilize the bicarbonate: H₂O +CO₂ →H₂CO₃ H₂CO₃ (dissolved in water)→HCO⁻₃ + H⁺ HCO⁻₃+ Na⁺ → NaHCO₃ (requires heating the sodium, I think) - Disclaimer: I'm no chemistry expert, although I did it (badly) at A-level.
The 2nd reaction is catalysed by an enzyme called carbonic anhydrase. After it has formed it separates (dissociates) into hydrogen ions (H+) and hydrogen carbonate ions (HCO3-).
Impressive, first time seeing anything like this, if you had solar panels and a power wall battery system would you see a quicker return in your investment? Also that average saving you’d make each year be mostly off just your gas and electric bill or would that be selling back to the grid aswell depending on your usage? Good work!
Hi Scott. You can sell back to the grid through the current SEG scheme. The output is low and constant though so shaves off your vase load. May or May not be worth it. Problem with solar and battery is that it ads expenses so I think may even elongate payback. Its a great combo though and one in getting in the long term!
Hi James, you have complete flexibility to either store it in a battery or use it all if its a big house. Alternatively there is now the Smart Export Guarantee which rewards for exported energy on a fluctuating tariff.
2.5-3p per kWh of gas, those were the days. Guess this saves even more with the higher energy costs now. Interesting tech, surprised at the efficiency. Still fossil fuel based at the end of the day mind. Heat pumps powered by renewables and nuclear are the future, with some battery backup thrown in
Could you buy an electrolysis that can make hydrogen gas for your gas force air or boiler to burn to heat your home? Would hydrogen burn at the same temperature as natural gas?
You could but it would be cheaper to use the electricity directly to heat.. you use alot more electrical energy than you produce in hydrogen. Yes it burns hotter.. this product does not virtually tho. Its cold fusion.
@@HeatGeek What do you mean by it's cold fusion? By the way, what if you fed the electrolysis with regular 120 volts then step the power up with a transformer to over a thousand volts?
@@sigglass2183 it's a chemical process.. not combustion. The hydrogen is unstable so wants to bond woth the o2.. when it does its exothermic.. its makes hot water.
To truly make a difference to the carbon footprint from uk household, we need to feed clean hydrogen in the grid either green H2 from renewable sources or blue hydrogen from gas with carbon capture and storage with more 98% of your carbon is sequestered onto the ground. With this fuelcell you are releasing carbon to the atmosphere which defeats the whole purpose. But i still enjoyed the video ! And it is a good concept
Although that's true.. our grid or production is absolutely no where near there yet. We are atleast 20 years away. This is an interim technology. Thanks for your comment 👍
@@bluepointglobal9566 its a gimik imo.. the vitovalor hydrogen fuel cell is already ready for up to a 30% mix and the viessmann 200 has been hydrogen ready for some time.. just not making the big deal others are using as a marketing op. Personally I think heat pumps will probably win the race.. all subjective though!!
Clever kit but running on gas, albeit efficiently makes it a legacy technology before you start. If it had built in electrolyser and worked off water then that would be impressive, but compared to relatively low tech regular heat pumps, solar thermal and solar PV it's all far too compex and unecessary.
Thabks for commenting. Electrolysers are around 25% efficient so not viable. This is an interim technology not a long term one. But currently saves the supply chain much more than a heat pump and will do for at least the next 15 years.
Fuel cells are about as efficient as the state of the art Combined Cycle Gas Turbines. Those typically come at 300 MW at the smallest. Something I've wondered a lot about for cold climates is combining fuel cell CHP with heat pumps. On paper, it means needing a smaller fuel cell and heat pump compared to either in isolation. The big question is if such a system is too complicated to be worth it.
Fuel cells are obly low efficiency in that way if you dont recapture and use the heat like this does. If you utilise the heat locally they are up to 92% efficient. Agree with you on the heat pumps.. could be a little too complex on small domestic but perhaps on large commercial.
I'm using an AC which is a heat pump too, we combine it with solar and it works great. In summer when it's hot and sunny, most of the time it's free to use the AC and in winter, on sunny days you can heat for free but even if it's not sunny the heat pump still is very economical to run. I think AC heat pump systems and solar work together very nicely.
@@silverismoney thats exactly what heats our offices.. we have battery storage too to assist with the fact the sun doesn't shine when heat load is highest
An awful lot of optimism and generous ‘could be’ projections here. I understand all the left side operations but I fell daunted by the right side complexities. Carry on, of course! There is no option but, it is nowhere near a viable alternative to the mass domestic heating and hot water market…That will take time.
Hmm, not sure about this. Just say CO2 and not carbon, just sounds sneaky. OK, so may be better than output from gas power station, but electricity grid is a mix of generation sources, and moving towards lower CO2. How long before the grid outperforms this. I'm guessing long before paid back.
cost off these units need to come down to make it liable even heat pumps would not want one installed in my house watching the meter spin round when the electric comes in to top up the hot water condensing boiler unvented hot water cylinder underfloor heating weather comp set your heating curves you can't go wrong
Depends what your coming from.. if your upgrade is already costing 8k. Then the extra 4 k is easily worth it. As always there is no panacea or one size fits all. Heat pump can be 4k to 40k.
Why no discussion about splitting (DC Electrolysis) of Urine instead of water. It only takes 1/3 of the energy to split Urine compared to water. And Urine contains twice as much hydrogen than water!!
The converted unit he is talking about that separates the H from the carbon isn't the neat process that he simply glosses over. Carbon is not a gas that simply can be vented to the atmosphere, rather the process removes the carbon as CO2 and releases this gas to the atmosphere, hey, just like my diesel truck. So what are all the greenies bitchin' about, isn't it the evil CO2? I am not saying that this system doesn't work, it's really a neat piece of work, it's just that it doesn't get you where you want to go.
This is an interim technology. There isn't a carbon free technology for heating yet.. power stations produce 500-900 g co2 per kwh.. this produces 210.. its a vast improvement
Yes, but he's producing less CO2 by generating electricity where it's used and making use of the heat than if he used the same amount of power from a distant power station, where the waste heat is discarded (in those huge cooling towers) and there're big transmission losses in getting the power to the users.
Why does this fuel cell blow the carbon into the atmosphere when the industrial way of making hydrogen uses carbon capture? Does not seem worth the money putting that massive boiler in
Don't see the benefit if you live in locations having hydroelectric power generation. Would be better if the carbon were precipitated as powder rather than as a gas. That way it would have zero CO2 emissions.
Because that's only done at 20% efficiency. If we use green electricity then you may aswell run a heat pump. 1kw green electricity gives 200w of hydrogen, or 3000w of heat.. the long term goal is the electrify the world
@@clarkjones2579 well.. thay depends its 20% commercially.. but if you use the heat 80%. Domestically I.e. these units it's 92.5% ad it uses the heat and all jept in 1 neat box
@@HeatGeek that's pretty cool. What about using electrolysis from excess energy say a solar array to power water heater / furnace etc? It would seem to me the efficiency is less important when it's coming from excess energy from renewables
The electricity from this unit is 210g/kwh.. that is SIGNIFICANTLY less than the number 1 generators today which are Gas fired power stations which produce at 500-900g/kwh.. The efficiency comes from recapturing and using the heat that would usually be lost to atmosphere. Ignoring the fact we still also use coal from time to time!!!
@@HeatGeek well at least you’re reducing your carbon foot print. Better than conventional power I guess. I have no room to talk. I dont use any green tech right now but am looking into all the options available.
Consider is a hot water store and you don't need cold water storage or header tank and the actual fott print isn't a mile off what you'd require for a boiler, cylinder, calves, and interconnecting pipework...

@@jrisner6535 heat pumps provide heat.. not power. Its comparing apples and pairs. heat pumps increase grid intensity of power. Every kwh of power generated from this unit is only 210g/kwh .. thays 1 less kwh produced from 500-1000g/kwh coal or gas station. We need interim tech.. Currently less than 1% of systems are heat pumps.. thso country switch tomorrow the grid intensity would be astronomical and these would be even more important.. Whats more.. these produce when the grid is the most intensive.. in winter an still days..
Way too complicated, as I toss a stick on the fire here in Nova Scotia Canada, I can run our home up to 33 C even when it's minus 30C outside, even open the patio door in this weather to let some heat out If I wish for about 585 English pounds or $783 U.S dollars a year. So far anyway, not that it doesn't creep up every year or so. This system when doing the converting is still putting the carbon back in the atmosphere. If I get desperate I can look into a wood gasifier to generate power as well as solar, which I plan on anyway at some point Thank goodness these folks are doing research though, at least they're trying. Maybe instead of wars and space missions that cost Trillions, we could put a bit more money into what should really count in this world. Mind you every dollar the west spends now will just impoverish their grandkids. THINK OF IT THIS WAY, THERE IS NO MORE MONEY JUST DEBT AND INTEREST TO PAY ON IT.

Disappointed that you're still depending on carbon fuels. Let us know when you obtain a fully Hydrogen-based one. The idea here is to stop suckling the teat of big oil and big energy companies and gain energy dominance and independence. :( JSYK you can manufacture pure Hydrogen gas by utilizing Gallium-laced Aluminum introduced into Distilled water. (you can generate COPIOUS amounts of this, all 100% energy free.)
This is 2 years old. Also.. hydrogen is mental and will always be a last resort for domestic heating. This unit is still lower carbon than a heat pump but not for long
Bad idea. Ridiculous actually. Better to use photovoltaic and windmills placed all around the country to supply 24/7/365 electricity. It is ALWAYS windy somewhere. Sure, that would require building a lot of windmills all around the country and maintaining them. But that's not a big price to pay for clean, renewable, energy self-sufficiency. Furthermore, by storing, say 250 to 500 gallons of hot water in insulated tanks, you could take care of all of your heating and hot water needs 24/7/365.
@@HeatGeek For now simply get your electricity from photovoltaic panels on your roof and from the grid. Also, store any excess electricity your produce as hot water because your electric company probably pays very little for electricity you sell to them. Finally, insulate your house well and install a heat pump. Done. Hydrogen fuel cells are like flying cars.. they are still too expensive. One day, hydrogen fuel cells will likely be cost-effective, but we aren't there yet. Converting natural gas to hydrogen to run a fuel cell is a nice science experiment for students, but it's way too expensive for supplying electricity to an ordinary home.
@@yekutielbenheshel354 photo voltaic produces when less power is needed. This fits a gap.. its not forever where.. but it fits a gap.. we push air source before this. As for being too expensive.. tell that to the 70 or so customers we've installed them for. The solution is currently a varied approach.. not 1 solution.. untill we have electeicitt storage down at least
@@HeatGeek Do you have a link, for example, to a Google Sheet which shows the cost to install, run, and maintain the systems you installed? Were these residential installations? I am assuming that they were. I am certainly not a residential hydrogen fuel cell expert, but my cursory research had indicated that residential hydrogen fuel cells are almost always prohibitively expensive. Did you build these systems for residences that are off-grid? What is the typical profile of the customers who bought these systems? I'm merely taking a wild guess but are the typical customers, perhaps, wealthy people people with a vacation residence that is off-grid?
@@yekutielbenheshel354 no sorry. I have one in my house.. they cost around 13k gbp to install. Wether it's worth it or not depends on the spark gap which is peice difference between lecy and gas.. wider the better.. and if you needed a new system anyway.. its o ly the extra that needs to pay back if you meed a new heating system anyway.. not yhe whole cost..
It's not a long-term solution, but it is an interim one until even better ones can be adopted. The source of primary power can be uprated at that time. There is a difference between "green Hydrogen, and blue Hydrogen": Green hydrogen is produced using electrolysis of water, and blue hydrogen utilizes natural gas. Green hydrogen represents a major opportunity for governments and private business to harness a valuable, sustainable energy resource in the coming decades

@@HeatGeek That's actually a terrible source!
Firstly, the bias is clear from the start. It's a pro nuclear paper that concludes that nuclear has the best low carbon results.
Secondly, it states a low, mean and higher result, but does not differentiate for CCGT or OCGT. It's clear that the lower value is for CCGT and the higher for OCGT, but they've used the mean of the studies. This ignores the simple fact that CCGT is in the case of the UK the base load generator, and OCGT only operate for approx 1hr a day, and are significantly smaller in size.
And finally, that's a lifecycle analysis, not a generation analysis. You've not quoted the lifecycle analysis of the domestic system, only the operational impact.
Awesome guys, I did the training on the vitovalor at viessmann and it was excellent.

Good stuff. It is worth clarifying what is the vented waste product from the reformer carbon or carbon dioxide?
Carbon dioxide. Methane steam reforming outputs H2 and CO2
Another great video Adam, well done 👍
Thanks Tell. Any ideas for future vids?
is the hydrogen separated from the natural gas just before the boiler
how is is this done some filter or catalyst what ihappens to the left over gas and what is it make u p

I have a lot of respect for you and what you do but not once in your arguments for heat pumps do you acknowledge the fact that if we install lots of heat pumps we will have to have a lot more gas fired power stations. I would love to heat the argument for taking out gas boilers and replacing them with heat pumps.
I completely agree with putting in heat pumps where you have LPG or direct electric heating but not as a substitute for gas boilers.
At the moment the public are being duped.
Hi Roger
Yes there is a huge task with electrification. The wind turbines currently being built and planned absolutely dwarf the current installations. There other ways to attack this issue too, for example the time of use tariffs and also storage to level peaks and troughs in demand and promote use of power only in higher times of high renewable generation.
There's also decentralised units, for example the vitovalor hydrogen fuel cell in my home helps support the grid quite well, we barely draw any power. Heat pumps aren't the only solution. Just the most forward thinking. Ide love to show you the hydrogen fuel cell sometime and perhaps have a chat about heat pumps? 😁
Errr...no Roger. You are part of the duping. The UK may not be handling adoption of technology well, and you're part of that. I suggest you do some reading of the massive amounts of info published by the National Research Council of Canada on it, along with the Cdn Mortgage and Housing Corporation, and Dept of Natural Resources. Norway's domestic market is 60% heat-pump, Sweden is 43%. In Europe, out of 21 countries, the UK is tied for last as per adoption.
Viessmanns are Canadian, eh? Canadian Government hosts huge amount of research on-line for heat pumps too.
Really good video adam, really interesting
Thanks Paul. Much appreciated.
Can it output DC or would it need to be rectified before storing into battery cells?
Is there RHI for this?....looks very interesting
No.. it had FIT when it was around
I think you could just add water to the co2 exhaust and make carbonic acid, from which you can get bicarbonate and hydrogen ions.
Use the H⁺ ions on fuelcell and add sodium to stabilize the bicarbonate:
H₂O +CO₂ →H₂CO₃
H₂CO₃ (dissolved in water)→HCO⁻₃ + H⁺
HCO⁻₃+ Na⁺ → NaHCO₃ (requires heating the sodium, I think)
- Disclaimer: I'm no chemistry expert, although I did it (badly) at A-level.
The 2nd reaction is catalysed by an enzyme called carbonic anhydrase.
After it has formed it separates (dissociates) into hydrogen ions (H+) and hydrogen carbonate ions (HCO3-).
The massive issue with this unit is the size, that will not fit anywhere in my property, considering a standard boiler only just fits...
Would this work well with a hot water circulation system?
yes they have a secondary hot water connection.
Very pretty but what's the cost?
Great clip 👍
Thanks Carl. Any suggestions for future videos let me know.
Fascinating. Does it work well with propane as the fuel source?
No
So basically it's magic.
More please, we are listening.
Correct.
I need to get one
Would you still recommend one of these unit in todays climate?
We still regulalry reccomend these yes.. untill the grid is 98/99% clean (no gas) we will
Hi are they available to run off propane gas
No sorry.. small chance in the future
Impressive, first time seeing anything like this, if you had solar panels and a power wall battery system would you see a quicker return in your investment? Also that average saving you’d make each year be mostly off just your gas and electric bill or would that be selling back to the grid aswell depending on your usage? Good work!
Hi Scott. You can sell back to the grid through the current SEG scheme. The output is low and constant though so shaves off your vase load. May or May not be worth it.
Problem with solar and battery is that it ads expenses so I think may even elongate payback. Its a great combo though and one in getting in the long term!
What is this like with the recent price hikes on gas?
Less good ofcourse
thats pretty sweet, I do so little gas work but loads of ASHP now.. I feel like im missing out on the toys :D
Not much gas put where you are i bet! 🤣
How do you use all the power? With no FIT, just use battery storage?
Hi James, you have complete flexibility to either store it in a battery or use it all if its a big house. Alternatively there is now the Smart Export Guarantee which rewards for exported energy on a fluctuating tariff.

2.5-3p per kWh of gas, those were the days.
Guess this saves even more with the higher energy costs now.
Interesting tech, surprised at the efficiency. Still fossil fuel based at the end of the day mind. Heat pumps powered by renewables and nuclear are the future, with some battery backup thrown in
So is there a government grant for this ?
Did you say the carbon is blown outside!! What sprt of carbon footprint involved here??
LA CE PREȚ AJUNGE CU TOTIL UN ASTFEL DE CENTRALĂ ?
Could you buy an electrolysis that can make hydrogen gas for your gas force air or boiler to burn to heat your home? Would hydrogen burn at the same temperature as natural gas?
You could but it would be cheaper to use the electricity directly to heat.. you use alot more electrical energy than you produce in hydrogen.
Yes it burns hotter.. this product does not virtually tho. Its cold fusion.
@@HeatGeek What do you mean by it's cold fusion? By the way, what if you fed the electrolysis with regular 120 volts then step the power up with a transformer to over a thousand volts?
@@sigglass2183 it's a chemical process.. not combustion. The hydrogen is unstable so wants to bond woth the o2.. when it does its exothermic.. its makes hot water.
That’s is massive.
This is a condensing boiler then?
It has a condensing boiler in it.. aswell as a hydrogen fuel cell
To truly make a difference to the carbon footprint from uk household, we need to feed clean hydrogen in the grid either green H2 from renewable sources or blue hydrogen from gas with carbon capture and storage with more 98% of your carbon is sequestered onto the ground.
With this fuelcell you are releasing carbon to the atmosphere which defeats the whole purpose.
But i still enjoyed the video ! And it is a good concept
Although that's true.. our grid or production is absolutely no where near there yet. We are atleast 20 years away. This is an interim technology. Thanks for your comment 👍
@@HeatGeek correct, but i think we'll see hydrogen burning boilers much sooner. Baxi working on these already...
@@bluepointglobal9566 its a gimik imo.. the vitovalor hydrogen fuel cell is already ready for up to a 30% mix and the viessmann 200 has been hydrogen ready for some time.. just not making the big deal others are using as a marketing op.
Personally I think heat pumps will probably win the race.. all subjective though!!
Can it use lpg?
No but I believe they are working on it!
And cost of hydrogen, cost of the whole system?
Did you watch the video? Doesn't sound like it
Clever kit but running on gas, albeit efficiently makes it a legacy technology before you start. If it had built in electrolyser and worked off water then that would be impressive, but compared to relatively low tech regular heat pumps, solar thermal and solar PV it's all far too compex and unecessary.
Thabks for commenting. Electrolysers are around 25% efficient so not viable. This is an interim technology not a long term one. But currently saves the supply chain much more than a heat pump and will do for at least the next 15 years.
Would be great if it were more affordable for people. I wonder if they cost £12k in Japan.
Obly the fuel cell available in Japan.. not the unit in this form. Yes unfortunately its as expensive as a typical heat pump install which is a shame.
Fuel cells are about as efficient as the state of the art Combined Cycle Gas Turbines. Those typically come at 300 MW at the smallest.
Something I've wondered a lot about for cold climates is combining fuel cell CHP with heat pumps. On paper, it means needing a smaller fuel cell and heat pump compared to either in isolation. The big question is if such a system is too complicated to be worth it.
Fuel cells are obly low efficiency in that way if you dont recapture and use the heat like this does. If you utilise the heat locally they are up to 92% efficient.
Agree with you on the heat pumps.. could be a little too complex on small domestic but perhaps on large commercial.
I'm using an AC which is a heat pump too, we combine it with solar and it works great. In summer when it's hot and sunny, most of the time it's free to use the AC and in winter, on sunny days you can heat for free but even if it's not sunny the heat pump still is very economical to run. I think AC heat pump systems and solar work together very nicely.
@@silverismoney thats exactly what heats our offices.. we have battery storage too to assist with the fact the sun doesn't shine when heat load is highest
whats the muzak for?
Our target demographic like it
An awful lot of optimism and generous ‘could be’ projections here. I understand all the left side operations but I fell daunted by the right side complexities. Carry on, of course! There is no option but, it is nowhere near a viable alternative to the mass domestic heating and hot water market…That will take time.
Does anyone know if there is a heating oil equivalent
No sorry
But isn’t this a bit redundant? Oil/Gas > Hydrogen > Heat versus Oil/Gas > Heat. Like is it economical, cost effective?
Very much a case by case basis.. often not.. sometimes very

Clever stuff...but I suspect you need deep pockets to install one.
Hmm, not sure about this. Just say CO2 and not carbon, just sounds sneaky. OK, so may be better than output from gas power station, but electricity grid is a mix of generation sources, and moving towards lower CO2. How long before the grid outperforms this. I'm guessing long before paid back.
cost off these units need to come down to make it liable even heat pumps would not want one installed in my house watching the meter spin round when the electric comes in to top up the hot water

Depends what your coming from.. if your upgrade is already costing 8k. Then the extra 4 k is easily worth it. As always there is no panacea or one size fits all.
Heat pump can be 4k to 40k.
Why no discussion about splitting (DC Electrolysis) of Urine instead of water. It only takes 1/3 of the energy to split Urine compared to water. And Urine contains twice as much hydrogen than water!!

Have you never thought about making your own Hydrogen? Google Mike Strizki Hydrogen house, or CNG from your food waste and sewage?
Or just get a combi boiler for 2k simples
I'd take a Honda chp plant over this, personally.... Simpler.
The converted unit he is talking about that separates the H from the carbon isn't the neat process that he simply glosses over. Carbon is not a gas that simply can be vented to the atmosphere, rather the process removes the carbon as CO2 and releases this gas to the atmosphere, hey, just like my diesel truck. So what are all the greenies bitchin' about, isn't it the evil CO2? I am not saying that this system doesn't work, it's really a neat piece of work, it's just that it doesn't get you where you want to go.
This is an interim technology. There isn't a carbon free technology for heating yet.. power stations produce 500-900 g co2 per kwh.. this produces 210.. its a vast improvement
It would be good if you could just source the hydrogen from water.
Wait a minute isn't CO2 a greenhouse gas?
Yes, but he's producing less CO2 by generating electricity where it's used and making use of the heat than if he used the same amount of power from a distant power station, where the waste heat is discarded (in those huge cooling towers) and there're big transmission losses in getting the power to the users.
Global Warming, just like BLM, left right etc all a Soros project.
Why does this fuel cell blow the carbon into the atmosphere when the industrial way of making hydrogen uses carbon capture? Does not seem worth the money putting that massive boiler in
These feels as if it is extremely wasteful. I doubt that the conversions he states for efficiency is the full story.
Don't see the benefit if you live in locations having hydroelectric power generation. Would be better if the carbon were precipitated as powder rather than as a gas. That way it would have zero CO2 emissions.
Theres no panacea and no free lunch
Why not make hydrogen from water instead of natural gas
Because that's only done at 20% efficiency. If we use green electricity then you may aswell run a heat pump.
1kw green electricity gives 200w of hydrogen, or 3000w of heat.. the long term goal is the electrify the world
@@HeatGeek so natural gas to hydrogen is 30%? I suppose it can be considered a trade off for emissions in areas that require it
@@clarkjones2579 well.. thay depends its 20% commercially.. but if you use the heat 80%. Domestically I.e. these units it's 92.5% ad it uses the heat and all jept in 1 neat box
@@HeatGeek that's pretty cool. What about using electrolysis from excess energy say a solar array to power water heater / furnace etc? It would seem to me the efficiency is less important when it's coming from excess energy from renewables
@@HeatGeek though 90%+ efficiency is impressive, solar panels still under 20%!!
I thought the whole point was to reduce carbon emissions. Not separate it from CH4 and release the carbon into the environment.
The electricity from this unit is 210g/kwh.. that is SIGNIFICANTLY less than the number 1 generators today which are Gas fired power stations which produce at 500-900g/kwh..
The efficiency comes from recapturing and using the heat that would usually be lost to atmosphere.
Ignoring the fact we still also use coal from time to time!!!
@@HeatGeek well at least you’re reducing your carbon foot print. Better than conventional power I guess. I have no room to talk. I dont use any green tech right now but am looking into all the options available.

@@jrisner6535 heat pumps provide heat.. not power. Its comparing apples and pairs. heat pumps increase grid intensity of power. Every kwh of power generated from this unit is only 210g/kwh .. thays 1 less kwh produced from 500-1000g/kwh coal or gas station. We need interim tech..

So far anyway, not that it doesn't creep up every year or so.
This system when doing the converting is still putting the carbon back in the atmosphere.

Disappointed that you're still depending on carbon fuels. Let us know when you obtain a fully Hydrogen-based one. The idea here is to stop suckling the teat of big oil and big energy companies and gain energy dominance and independence. :(
JSYK you can manufacture pure Hydrogen gas by utilizing Gallium-laced Aluminum introduced into Distilled water. (you can generate COPIOUS amounts of this, all 100% energy free.)
This is 2 years old. Also.. hydrogen is mental and will always be a last resort for domestic heating. This unit is still lower carbon than a heat pump but not for long
Bad idea. Ridiculous actually. Better to use photovoltaic and windmills placed all around the country to supply 24/7/365 electricity. It is ALWAYS windy somewhere. Sure, that would require building a lot of windmills all around the country and maintaining them. But that's not a big price to pay for clean, renewable, energy self-sufficiency. Furthermore, by storing, say 250 to 500 gallons of hot water in insulated tanks, you could take care of all of your heating and hot water needs 24/7/365.
Untill we're there...
@@HeatGeek For now simply get your electricity from photovoltaic panels on your roof and from the grid. Also, store any excess electricity your produce as hot water because your electric company probably pays very little for electricity you sell to them. Finally, insulate your house well and install a heat pump. Done.
Hydrogen fuel cells are like flying cars.. they are still too expensive. One day, hydrogen fuel cells will likely be cost-effective, but we aren't there yet.

That isn’t a good idea, releasing carbon into the atmosphere, that isn’t very GREEN.
It's not a long-term solution, but it is an interim one until even better ones can be adopted. The source of primary power can be uprated at that time. There is a difference between "green Hydrogen, and blue Hydrogen":
Green hydrogen is produced using electrolysis of water, and blue hydrogen utilizes natural gas. Green hydrogen represents a major opportunity for governments and private business to harness a valuable, sustainable energy resource in the coming decades
