HydrogenPro says its 220 MW ACES Delta project in Utah is nearing completion, with all electrolyzers operating at full load, while the hub will store hydrogen in salt caverns with an energy capacity two to three times greater than that of all U.S. grid-connected batteries combined.
HydrogenPro said the 220 MW ACES project in Utah, United States, is nearing completion. HydrogenPro is the exclusive supplier of electrolyzers. “This project is one of the world’s largest sustainable hydrogen projects and is expected to have a significant impact on California’s power supply,” said the Norwegian company, adding that all 40 electrolyzers in all units have been running at full load. The Advanced Clean Energy Storage Hub (ACES Delta) is being jointly developed by Chevron New Energies Company and Mitsubishi Power to produce and store up to 100 tons of green hydrogen per day. Hydrogen will be stored in two salt caverns, each with an energy capacity of 150 gigawatt hours (GWh), to be fed back into the electricity grid when necessary. “The Energy Hub has a storage capacity that is two to three times greater than all grid-connected battery storage facilities in the entire United States combined,” HydrogenPro said.
Jena Researchers have collaborated with the University of Ulm’s Institute of Inorganic Chemistry I to develop a material that can store solar energy for several days and release it as hydrogen. “You can see it as a combination of a solar cell and a battery at a molecular level,” said Sven Rau, head of the German institute. The researchers used a water-soluble, redox-active copolymer for temporary energy or electron storage. Copolymers are macromolecules composed of various organic building blocks and forming a stable framework equipped with functional units with enhanced redox activity. The system achieves a charging efficiency of more than 80% and maintains this condition for several days. By adding an acid and a hydrogen evolution catalyst, stored electrons combine with protons to produce hydrogen on demand, with an efficiency of 72%.
Karlsruhe Institute of Technology (KIT) researchers have set a new runtime record with a compressorless hydrogen gas turbine. The burner, which features pressure boosting technology, operated for 303 seconds, surpassing NASA’s previous record of 250 seconds. “This achievement sets new standards for the use of hydrogen in energy supply,” says KIT saidadding that earlier this year the team successfully generated electricity for the first time using a hydrogen gas turbine without a mechanical compressor.
The German Federal Ministry of Transport (BMV) has presented financing certificates to transport companies across the country, including the Ruhrbahn, which will receive a grant of approximately €11.6 million ($13.7 million) for the purchase of 52 modern fuel cell buses. “Hydrogen offers a long range, short refueling times and great operational flexibility, especially in densely populated regions,” says Managing Director Ahmet Avsar, commenting on the impact in Germany’s Ruhr area. Since 2025, 19 hydrogen-powered public buses have been operating in the Ruhrbahn operating area, and another seven are expected by the end of 2026.
