ZeroAvia performed a 10-minute check flight this week for it claims to be the world’s largest plane powered by a hydrogen-electric engine. The UK firm’s 19-seat Dornier 228 testbed plane has been retrofitted with a full-size prototype hydrogen-electric powertrain on the left wing. “That is the most important ZeroAvia engine examined so far, and places the corporate on a direct path to a licensed configuration to be finalized and submitted for certification in 2023,” it stated. The plane has a 600 kW powertrain twin-engine on its left wing and a Honeywell TPE-331 inventory engine on the precise. “The hydrogen-electric powertrain consists of two gas cell stacks, with a lithium-ion battery pack that gives peak energy help throughout take-off and provides further redundancy for protected testing,” the corporate stated, which introduced that the hydrogen tanks and gas cell energy era techniques have been inserted into the cabin.

Chinese language researchers reported a superaerophilic / superaerophobic cooperative electrode that may enhance foam elimination in electrolyzers. The Chinese language Academy of Sciences and Beihang College researchers have launched titanium-based superaerophilic (SAL) stripes lined with gasoline cushions on a platinum-based electrode. Superaerophobic (SAB) electrocatalytic areas encompass the SAL stripes. The stripes act as gasoline channels to launch hydrogen. They famous that bubble adhesion to the electrode, bubble dispersion across the electrode, and poor dissolved hydrogen diffusion are frequent issues in electrolysis. “Benefiting from the improved mass switch, the overpotential for the SAL/SAB cooperative electrode at −10 mA cm−2 is barely −19 mV, in comparison with −61 mV for the flat Pt electrode,” they wrote in Advances in Science.

Egypt-Japan College of Science and Know-how The researchers discovered that hydrogen manufacturing techniques primarily based on waste warmth techniques at 22.91% provide the best total effectivity. The effectivity of the system ranged from 11.6% to 22.91%, whereas the extent of worth of hydrogen (LCOH) ranged from $1.19/kg to $12.16/kg, the researchers stated. “The bottom worth is obtained when waste warmth is used, adopted by the grid, PV panels, and wind generators. Wind turbine techniques usually are not advisable on the market at costs of $8/kg and $10/kg,” they wrote. in a brand new one article on Vitality Conversion and Administration.

Centrica Enterprise Options is working with Germany’s 2G Vitality to supply clients with 100% hydrogen-ready mixed and warmth energy (CHP) techniques in the UK, Eire, the Netherlands, and Italy. “With a return on funding of lower than 12 months for some initiatives, ready-made hydrogen CHP stays a simple win to save lots of power,” SAYS the corporate primarily based in England.

Fusion Gasoline signed an offtake settlement with Portuguese pure gasoline utility Dourogás for inexperienced hydrogen from its initiatives in Portugal. “This represents the primary Fusion Gasoline contract aimed toward mixing inexperienced hydrogen inside the Portuguese pure gasoline grid,” SAYS the Irish firm. The Evora facility is more likely to be commissioned this yr. The ability is predicted to supply roughly 40 tons of inexperienced hydrogen per yr.

Hydrogen from France (HDF Vitality) signed a memorandum of understanding with the province of Kinshasa, Congo, to construct and function a inexperienced hydrogen photo voltaic plant. “That is the primary undertaking of its type deliberate in Central Africa,” stated HDF Vitality. It stated it was contemplating a location within the southern a part of the nation.
