As there are no hydrogen reservoirs on Earth, hydrogen is more of a battery than a fuel. Using hydrogen as a battery could make a 100% renewable grid viable. Water electrolysis can be used to separate hydrogen, but the process uses more energy than the hydrogen provides. If this energy comes from coal or fracking, it's not green. If this energy comes from renewables ~ wind, solar, hydro, geothermal, tidal ~ then it is green.
Excellent point I have made to others. Think of a hydrogen fuel cell as a truly rapid recharge battery system. You use energy to separate out hydrogen. It contains the potential energy and in the fuel cell it becomes actual energy once again. To truly reach the industrial scale electrical needs we have in the modern world the only large scale “green” solution will be nuclear energy and Hydro. Tidal and geothermal are regional dependent. Solar and wind are micro producers. We’re already seeing that as solar grids large enough to even power a small town use up too much arable land. However, they are great for installation on houses and small scale production such as farms or small non manufacturing buildings.
No. If that worked you'd have an infinite energy loop, which is impossible. Hydrogen is a way of storing energy to be used later, but the input energy has to come from somewhere, like wind or solar power.
@@Archasus if you could use hydrogen for power generation let's say with a fuel cell for instance. What's wrong with using that electricity to power the electrolysis process of Hydrogen generation. Part of the hydrogen generated goes to your fuel cell. I'd like to know why this is a problem. And 2. Why would a loop be a problem. Where bu the water from the fuel cells goes into the electrilytic process of generating the energy. It wouldn't be a incite system as there will be losses. There is no such thing as a perpetual motion machine
so green hydrogen is simply Hydrogen produced with electricity derived from solar and wind power? Bah, sometimes I think people do and create useless word and concept
The key problem there is the recharging time. For the transportation industry (big trucks and trailers) sitting at a supercharger for an hour every 3 hours makes increases costs and problems. Multiple that problem by 300 million and you now have a catastrophe. Now if you can pull up to a Hydrogen station and “recharge” the fuel cell in about the same amount of time it takes to fill up a diesel tank, then you have no logistical problem. Also, power companies will tell you that their grids going to residential neighbourhoods cannot handle everyone plugging in a fast charger in their garage let alone most in North American needing two. Hydrogen stations have already taken that electricity for purpose built production facilities, stored the energy from it in hydrogen, and shipped it to a gas station for you to just stop by on the way back from the shops to fill up the fuel cell. Then when you stop on the accelerator the potential energy is releases back into electrical energy and water.

Hydrogen also has some significant disadvantages. It's was a little disappointing that these were not discussed.
Like what? For example?
BP would prefer that those were not discussed.
Instead of Solar powering is it possible to power the electrolysis process with the hydrogen produced?
No. If that worked you'd have an infinite energy loop, which is impossible. Hydrogen is a way of storing energy to be used later, but the input energy has to come from somewhere, like wind or solar power.

I meant it wouldn't be an infinite system*
Good content! But I would prefer a presentation with a few visual aids, recorded in a quiet environment, on both left and right channels.
I would like to start a similar project here in New Brunswick, Canada. How can I get started
no sound during the interview for me.

Total BS. Speaker seems to NOT understand basic physics, and then, there is the problematic "business case"
Let me know one thing. Here her voice is audible or not
First
Actually second
First!!
Let me guess ! She's French !
The energy required to make hydrogen you may aswel use the electricity to charge a car.
