World's First Energy Island - A $34BN Masterpiece!

Join us on MegaBuilds as we explore Denmark's groundbreaking venture into green energy with the world's first energy island! This $34 billion megaproject marks a pivotal shift towards renewable energy and showcases Denmark's leadership in sustainable development.
Denmark's Energy Island isn't just another construction project; it's a bold statement in the fight against climate change. Poised in the heart of the North Sea, this revolutionary initiative aims to harness the power of wind turbines on an unprecedented scale. It's not just about generating energy; it's about reshaping the future of sustainability.
Witness the colossal construction of numerous wind turbines, each a testament to the incredible potential of renewable energy. This megaproject goes beyond mere energy generation; it's a beacon of hope for a climate-friendly future.

Hydrogen electrolyzers have a really valuable design feature. Electrolyzers do not mind much if the energy going into them dips or surges. Therefore if you connect them to wind farms they continue to work as wind dips or surges.
This addresses one of the HUGE issues with green power, its intermittance.
The hydrogen can be used as a fuel or as a feed for green ammonia. Green ammonia is a reasonable substitute for LNG in power generation. Legacy coal power plants can also be modified to use an ammonia blend (Japan is way ahead on this already).
This project is not a pipe-dream, this sounds like a very reasonable business plan!

Absolutely agree! The flexibility of hydrogen electrolyzers in handling the variability of wind energy is a game-changer for green power's intermittency issue. The potential to transform excess energy into hydrogen or green ammonia offers a versatile solution, fitting well into existing energy infrastructures. Japan's advancements in ammonia-blended power systems are indeed leading the way. This project is more than just visionary; it's a practical step towards a sustainable energy future.

I fully understand windfarms but I don't understand the purpose of the "energy island". Is cheaper to build an island and convert the energy to hydrogen there than to use cables to move the electricity to the coast as normal? What benefit does the $34BN island provide? How much power could be stored on the island? Would it be better to channel the electricity to areas in Europe where they can use pumped hydro to store the power? I appreciate that requires cooperation between European countries and this might be a little ironic as I'm from the UK. It also didn't show how the hydrogen tanks could be protected against accidents, terrorists, or perhaps just the Russians or Chinese. Having all the tanks together like in the diagram is honestly just asking for trouble. Also, if it costs $34BN then why is 2/3 or the island parkland?

Use the excess energy to produce Hydrogen through electrolysis.

Nobody gives a rats ass what you think

@@madsbrandt598 Of course. The question is whether it's worth paying $34BN to store 3GWh of electricity (that's $11BN per GWh). For comparison the Swiss Nate De Drance pumped hydro battery cost $2BN and stores 20GWh (that's $0.1BN per GWh). Hopefully you can see why I'm questioning this.

Thank you for your comment! Your considerations are valid, but the energy island concept aims to centralize the gathering, storage, and distribution of renewable energy, addressing transmission challenges posed by offshore wind farms' distance from land. The $34 billion investment is multifaceted, covering not just energy generation and storage, but also the holistic development of the island with a focus on environmental sustainability and potential public and research use. While the initial capacity is 3GW, the project is designed to scale up to 10GW, significantly enhancing its long-term cost-effectiveness and overall value proposition.

From the comfort of my couch… 😂 I see the potential of the idea but would like to see how the North Sea behaves with those islands that is a “mega build” itself independently off what is it purpose. I would see more cost efficient to spend that money on HV grid distribution taking the electricity far enough your surplus energy supply meets the peak demand in the and vice versa. Win win
