Good ingredients but bad cocktail: Combining offshore wind and green hydrogen is still too expensive - Rystad Energy
13 Jan 2021
Several large-scale offshore wind farms are planned in the next five years in the North Sea. The area not only has plenty of ageing platforms and pipelines that could host production and transmission of hydrogen cheaply, but also salt caverns to store it at low cost.
Rystad Energy has therefore looked at the economics of blending green hydrogen production with offshore wind development. This hybrid approach offers promising elements, but the high costs – at least for now – remain a show-stopper.
Rystad Energy’s modelling is based on combining a green hydrogen project with an offshore wind farm of 1 gigawatt (GW), assuming that about half of the farm’s generated power is excess and used for hydrogen production. The analysis shows that at current break-even costs, the bulk of the hydrogen produced needs to be sold at EUR 5.1 per kilogram (kg), or

New approach to III-V tandems sets 32.9% efficiency record
A collaboration between the U.S. National Renewable Energy Laboratory and Australia s University of New South Wales has yielded a new efficiency record of 32.9% for a tandem cell device utilizing III-V materials. Key to the achievement was a new technique enabling the researchers to take advantage of quantum wells in the material that serve to trap charges and enable tuning of the cell bandgap to absorb more of the light spectrum.Solar cells manufactured from gallium arsenide (GaAs) and gallium indium phosphide (GaInP) have long yielded some of the highest conversion efficiencies of any technology, .
