Federal Institute of Know-how in Lausanne (EPFL) researchers have developed a thermally built-in photoelectrochemical gadget to generate hydrogen by concentrated photo voltaic irradiation. A 7m-diameter parabolic dish concentrates daylight right into a 144 cm^2 reactor the place water is pumped, attaining a solar-to-hydrogen device-level effectivity of greater than 20% at an H2 manufacturing charge of >2.0 kW. The scientists revealed their findings from the venture, which is the primary system-level demonstration of photo voltaic hydrogen technology, in a current version of Pure Power. Warmth and oxygen are captured and used, and an EPFL startup, SoHHytec, is commercializing the system to scale up the expertise.
Sapienza College of Rome scientists collaborated with Sorbonne College, CNRS, and SISSA to create a section diagram of hydrogen and deuterium at excessive stress and low temperature. They found that the atomic metallic hydrogen section varieties at 577(4) GPa, and molecular hydrogen modifications from the metallic section to a different molecular construction (section VI) at 410(20) GPa. The researchers stated in a current paper on Nature Physics that anharmonic vibrations of the nuclei make the metallic hydrogen section secure at larger pressures than beforehand estimated.
Energy plug has equipped three containerized electrolyzers to Hungary-based Ganzair for 2 tasks. One is the Bukkabrany Photo voltaic PV Park venture, which is able to generate 850 kg of hydrogen per day to be combined with the native gasoline pipeline to warmth properties and companies. One other venture, Aquamarine, will attempt to use hydrogen for storage functions. The New York-based firm says it can reveal the long-term power storage potential of inexperienced hydrogen. The three 1 MW containerized electrolyzer techniques will probably be put in later this yr. That is Plug’s first electrolyzer system equipped to the EU and is anticipated to be the primary in operation.
Glenfarne and Samsung Engineering have launched a collaboration settlement to finish feasibility research for a number of inexperienced hydrogen and ammonia tasks in Chile, as a part of Glenfarne’s just lately introduced Hydrogen Fuels Initiative. “Inexperienced Pegasus, the primary venture developed as a part of the settlement, has as much as two gigawatts of photo voltaic PV put in capability and is estimated to supply 459 kilotons (kton) of inexperienced ammonia and 89 kton of inexperienced hydrogen per yr . Inexperienced Pegasus will primarily concentrate on exporting to Asia, notably South Korea, and Europe, the place Glenfarne maintains many enterprise and industrial companions,” SAYS Glenfarne.
