The UK is the latest country to accelerate plans to develop hydrogen in its push to reach net zero. It’s not the first time hydrogen has been flagged by the scientific community as a possible wonder fuel. So, what’s different now?
Thirteen kilometres off the coast in Scheveningen in the Netherlands sits a large oil and gas platform, known as Q13a,1 a planned test site for the world’s first offshore hydrogen plant. From it, the plan is to harness wind and solar energy to split water into its component parts – hydrogen and oxygen – via electrolysis. The essential raw material is desalinated sea water; the energy source is renewable, and there will be no carbon produced from using the output as fuel.
“The goal is to obtain valuable lessons for successfully integrating offshore energy systems to support the acceleration of the energy transition,” explained Lex de Groot, managing director of Neptune Energy, a small North Sea explorer.2
It is early days for Q13a, but the concept has similarities with one set out almost a century ago. In 1923, the biochemist J.B.S Haldane presented a paper in Cambridge3 in which he wrote: “There will be great power stations where during windy weather the surplus power will be used for the electrolytic decomposition of water into oxygen and hydrogen.” Today’s experimental ‘world first’ does not feel too far removed from Haldane’s vision.
