H2FLY has completed preliminary filling tests with a liquid hydrogen tank for its HY4 aircraft, while Wingcopter has announced the development of a hydrogen-powered delivery drone.
South Korean researchers have found that the emission factor of a residential polymer electrolyte membrane fuel cell (PEMFC) system – fed with hydrogen from natural gas reforming (NG-PEMFC) – is more than double the GWP of a similar system. supplied with hydrogen from a PV-powered water electrolyzer. “In the case of NG-PEMFC, the GWP was 3.72E-01 kg-CO2eq/kWh, the carbon dioxide emissions caused by the use of city gas during the life cycle process are about 20.87%, the carbon emission ratio according to the reformer combustion. burner was 6.07%, and the direct CO2 emission ratio of reformer air emissions was 73.06%, indicating that reformer carbon emissions accounted for more than 80% of GWP, the researchers wrote in the paper “Global Warming Potential of a 1 kW Polymer Electrolyte Membrane Fuel Cell System for Residential Buildings in Operation Phase,” which was published recently Energy for sustainable development. System GWP supplied with hydrogen from a PV-powered water electrolyzer was 1.76E-01 kg-CO2eq/kWh. The researchers found that the lifetime carbon dioxide emissions contained in PV production accounted for more than 99 percent of the GWP.
A hydrofoil and ZAL Center of Applied Aeronautical Research have launched a partnership to develop delivery drones powered by green hydrogen. “The most important requirement of the development project is to increase the duration of the flight while maintaining the characteristic flight ability of the Wingcopter”, said ZAL.
Germany’s Chemnitz within the precincts of Is by applying to become a HyPerformer region in cooperation with HZwo within the framework of the HyLand regional funding program of the German Federal Ministry for Digital and Transport (BMDV). BMDV is expected to make a decision by the end of April. The goal is to achieve scalable hydrogen production and flexible distribution through a wide network of refueling stations, in addition to the procurement of hydrogen vehicles throughout the region.
