About 400 GW of solar, wind needed per year to keep mercury rise below 1.5 C

Academics in Denmark and Berlin have calculated Europe will need 400 GW of new solar and wind facilities per year from 2025 to 2035 to contribute to capping global temperature rises, in line with the Paris Agreement.

The Hydrogen Stream: Renault presents electric-hydrogen hybrid car with range of up to 800 km

In other news, Shinshu University researchers developed a graphene-wrapped molecular-sieving membrane that is reportedly 100 times more efficient than that of conventional polymer separation membranes. Topsoe aalso nnounced the construction of the “world’s largest electrolyzer production facility,” and Toho Gas said it would produce blue hydrogen in Japan for local consumption.

The Hydrogen Stream: Heavy-duty hydrogen refueling station in Germany

Everfuel has signed a deal to build a hydrogen refueling station in Germany, while the European Hydrogen Backbone initiative has accelerated its own program to produce 20.6 million tons of renewable, low-carbon European hydrogen. Separately, the UK government published its hydrogen investor roadmap to 2030.

Monolithic fuel cell with power density of 5.6kW/L

An international research group has developed a solid oxide fuel cell that may be used in vehicles. The monolith device has an active cell area of around 18 cm2 and was built through common manufacturing processes. It was found to achieve a high power density of 5.6 kW/L, which the scientists said is comparable with that of the best performing fuel cells based on ceramic anodes.

The Hydrogen Stream: Hydrogen-powered trains for the German network

Elsewhere, the Danish government announced a plan to deploy up to 6 GW of electrolyzer capacity by 2030 and Germany and Norway agreed to conduct a feasibility study on large-scale hydrogen transport, including via pipeline.

New solar tiles from Denmark

Danish BIPV specialist Dansk Solenergi has added two more tiles to its product range – an 18.15%-efficient dark grey panel and a 16.7%-efficient terracotta product. Both panels have an operating temperature coefficient of -0.34% per degree Celsius.

Unsubsidized utility scale solar changing shape of Danish PV market

In a short interview with pv magazine, Flemming Vejby Kristensen, from the Danish PV association Solcelleforening, explained the surprising performance achieved by Denmark’s PV market in 2021, in which around 667.6MW of PV capacity was deployed. Around 94% of this growth is coming from large scale unsubsidized solar projects and the segment’s main driver has been the willingness of big corporations to buy green electricity under bilateral PPAs.

Chint to supply modules for 329MW of Danish solar

The Chinese solar module manufacturer and its German EPC partner Intec have landed a contract to develop BeGreen’s Danish solar portfolio.

Storing solar power with grid-scale molten hydroxide

Seaborg Technologies, a Danish manufacturer of molten salt nuclear reactors, has turned a technology that was originally developed for nuclear power into a large-scale storage solution for wind and solar. It has developed a storage system that uses renewable energy to heat salt with electrical heaters, based on two-tank molten salt storage designs developed for concentrated solar power plants.
