green hydrogen

Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.

Oil giant Chevron said it expects its new solar-to-hydrogen project in California to produce about 2.2 tons of hydrogen per day by 2025.

Energy Vault has begun construction on a 293 MWh green hydrogen and battery storage facility within utility Pacific Gas & Electric’s service territory in northern California.

SBM Offshore has installed a floating facility in Monaco to produce green hydrogen from renewables, while Axpo and its partners have revealed plans to use hydrogen to power a passenger vessel in Switzerland.

The European Hydrogen Bank’s pilot auction has drawn 132 bids, exceeding the available budget, while Australia has finalized an agreement to build a hydrogen hub.

Scientists in Korea have developed a compressed air storage system that can be used as a combined cooling, heat, and power system and provide heat and power to solid-oxide electrolysis cells for hydrogen generation. It showed an overall roundtrip efficiency of 121.2% and over-unity efficiencies in the range of 100% to 120%.

Hive Energy is in the process of securing approval to deploy 800 MW of electrolysis capacity and 1.1 GW of PV in Spain’s Albacete province, as part of a broader plan to install 9 GW of wind and solar power, along with 4 GW of electrolyzers by 2030.

A new Stanford University report shows that the transition to clean energy could help many countries to reduce their annual energy costs by around 61%.

Bharat Petroleum Corp. Ltd. (BPCL) has developed an alkaline electrolyzer in collaboration with India’s Bhabha Atomic Research Centre (BARC).

Corsica Solar says its 150 kW electrolyzer will be powered exclusively by PV electricity during peak hours.
