The Hydrogen Circulation: Qatari researchers unveil PV-led barren region agriculture device
Researchers in Qatar possess proposed a checklist voltaic-powered freeze desalination and electrolysis device for freshwater and green hydrogen manufacturing, while BP says it has made a final funding determination for its 100 MW Lingen Green Hydrogen mission in Germany.

Hamad Bin Khalifa University researchers possess proposed a standalone checklist voltaic-powered freeze desalination and electrolysis device to assemble freshwater and green hydrogen from brackish groundwater in far off barren region regions. They faded a 10,456 m² device with ice storage air conditioning, metallic hydride canisters for hydrogen storage, and a gasoline cell to address checklist voltaic irradiation fluctuations. They suggested pv magazine that the “device functions spicy integration of bifacial photovoltaics, brackish groundwater manufacturing, freeze desalination with ice storage air conditioning, green hydrogen manufacturing, storage, and gasoline cell, thermally coupled with hydrogen storage canisters,” in articulate to enhance agricultural actions in sizzling barren region environments. Researcher Nurettin Sezer acknowledged the device makes exercise of LaNi5 as a storage medium. They deployed bifacial modules with 23.6% effectivity, a PEM water electrolyzer with 74.5% and 58.8% voltaic and energetic effectivity, and a gasoline cell with 64.6% and 62.5% voltaic and energetic effectivity. They acknowledged in a contemporary sight in Desalination that the device generates 2.4 MWh/day of electricity, 52.8 m³/day of glossy water, 6.3 MWh/day of air conditioning, and 177 kg/day of hydrogen for hour of darkness energy storage. It accomplished 17.8% energy and 13.5% exergy effectivity at some stage in the day, and 56% energy and 34.9% exergy effectivity at evening. Sezer acknowledged that while groundwater manufacturing, desalination, and ice storage bustle constantly, the electrolyzer simplest operates at some stage in the day and the gasoline cell at evening, with extra technoeconomic research soundless required.
BP has made a final funding determination (FID) for the “Lingen Green Hydrogen” mission in Lower Saxony, Germany, which is ready to be supported by funding from the Well-known Mission of Usual European Pastime (IPCEI) program. It acknowledged the 100 MW plant, positioned subsequent to its Lingen refinery, is expected to assemble up to 11,000 hundreds green hydrogen per year and could well well moreover be straight connected to the hydrogen core network. It plans for the power to be its supreme industrial-scale green hydrogen manufacturing plant up to now and the principle this could well well well fully own and operate.
SunHydrogen has carried out an illustration of its green hydrogen skills on the 1m² scale. In October 2024, it acknowledged that its 100 cm² hydrogen modules, manufactured in collaboration with CTF Photo voltaic, demonstrated 10.8% checklist voltaic-to-hydrogen effectivity on the Honda R&D facility in Japan. “With this 1 m² demonstration beneath our belt, we are able to launch up the positioning need direction of for better pilot demonstrations,” acknowledged Syed Mubeen, SunHydrogen’s chief scientific officer.
