Cheapest long-duration storage for systems with high renewables
National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications.
German researchers want to reduce manufacturing costs for electrolysers by more than 25%
A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolyzers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.
Spanish consortium wants to simplify hydrogen production through photoelectrocatalysis
Spanish energy giants Repsol and Enagás are planning to build an electrolyzer based on photoelectrocatalysis at an industrial complex owned by the oil company in Puertollano in 2024. The device receives direct solar radiation and with a photoactive material it generates the electrical charges that cause the separation of the water molecule into hydrogen and oxygen.
Australia’s largest planned renewables zone ‘swamped’ with 34 GW of capacity
Australia’s newest planned renewable energy zone has been “swamped” by investors, with the New South Wales government revealing that 34 GW of new solar, wind and energy storage projects have already been proposed.
