Hydrogen

In other news, German energy company Uniper said it will test a new salt cavern built for hydrogen storage, while Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen.

Attendees at the Renpower Kenya clean energy event in Nairobi were told there will be a changeover in incentive schemes in 2022 with mature technologies no longer benefiting from fixed payments.

In other news, Toyota unveiled plans to roll out light-duty hydrogen fuel-cell trucks for the Japanese market next year and the UK has launched a contract for difference scheme for large scale hydrogen projects. Furthermore, Japanese scientists have designed a ruthenium complex with a nitrogen-containing organic compound to improve high-temperature proton conduction in fuel cells.

Spanish scientists developed a proton exchange membrane fuel cell with a bipolar plate based on a nature-inspired structure. This architecture, according to its creators, shows remarkable performance when operating at high relative humidity values of 90%.

EPRO Advance Technology has developed new silicon materials for hydrogen production, while Helmholtz-Zentrum Hereon researchers have shown that hydrogen storage materials can be produced from recycled industrial waste.

Researchers at Deakin University in Australia have discovered a novel way to separate, store and transport large amounts of gas without waste.

New research from Ireland shows that depleted oil and gas reservoirs may be used to store hydrogen at a cost of $1.29/kg. According to the researchers, underground hydrogen storage may benefit from the technological maturity of the geologic storage of natural gas and CO2, which are associated with decades of established knowledge.

Researchers from the Indian Institute of Science (IISc) developed a two-phase hydrogen production technology that is capable of using steam to produce hydrogen from biomass. Furthermore, an Indian-Norwegian consortium is developing green ammonia in Oman, Toshiba is starting research on hydrogen production from geothermal energy, and Thyssengas is selecting personnel for the conversion of around 20% of its gas network.

Vattenfall and its partners have finished building a 100-cubic-meter underground facility to store green hydrogen.

On day two of the pv magazine Roundtables Europe event, we focused on minimizing land competition for PV with dual use applications, how high efficiency n-type cells are progressing toward large-scale manufacturing at competitive cost, PV module design choices, how unsubsidized power purchase agreements can adapt and evolve, and the determining conditions for solar-plus-storage and solar-plus-hydrogen business models, among other key PV issues. The last five sessions are now available to view on demand.
