A major investor in offshore wind farms is starting a new company, Copenhagen Energy Islands, with the aim of constructing artificial islands in the North Sea that combine wind power and hydrogen production.
Backed by Copenhagen Infrastructure Partners, it plans to invest €150 billion ($163 billion) in the next few decades to create islands with large wind turbines for electricity generation and offshore green hydrogen production.
“Offshore wind is simply the cheapest source of renewable energy in Europe available on a grand scale,” said Jakob Baruël Poulsen, managing partner of CIP.
“The current installed stock of offshore wind will be increased tenfold at least. And it’s very clear that if that is to happen, we need to do it differently than how we are doing it currently. And energy islands offer a number of very important advantages.”
However, overcoming technological and political challenges is supposedly crucial for this ambitious initiative.
The concept has already gained eyeballs in the European Union, which aims to achieve a target of constructing at least 300 gigawatts of offshore wind in the coming years, surpassing the current capacity by over tenfold.
The challenges to bringing this project to life come with a set of hurdles. Producing green hydrogen on a large scale is not yet a reality, and offshore placement of machines introduces difficulties, including securing a fresh water supply for the electrolysis process.
Additionally, the islands might be vulnerable to attacks, undermining the advantages of decentralized renewables.
