Luxaviation, a business aviation services group, has recently published a sustainability report highlighting advancements in decarbonizing ground support services. American firms are showing commitment to hydrogen-powered aviation by agreeing to purchase 100 ZeroAvia hydrogen-electric engines for CRJ700 Regional Jets. In contrast, Universal Hydrogen faced financial challenges and had to close its business due to the inability to secure additional funding. Helios Horizon is pushing the boundaries of electric aviation with plans to conduct test flights in converted Pipistrel Taurus light aircraft targeting altitudes above 40,000 feet. Additionally, MagniX has entered the energy storage sector with Samson Batteries, aiming to support multiple electric propulsion systems for aircraft. The aviation industry also experienced other developments such as Sirius rebranding its planned hydrogen business aircraft, SAF Coalition adding 10 new members to its group focused on sustainable aviation fuel, and two bizjets being spray-painted at London Stansted by protesters who breached airside security.
