Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

We tested whether anaerobic digesters could operate at lower temperatures without losing methane production. Pilot‐scale reactors were run at 48°C or 55°C. Methane yields and gas quality were similar. Lower temperatures reduced volatile fatty acids and supported more diverse microbial communities.

Abstract The vision of using microalgae to obtain organic chemicals in a carbon‐neutral manner is intriguing. It promises to produce various substances including biofuels by photosynthesis, without competing with agricultural land. Processes have been established whereby microalgae undergo a growth phase followed by a stress phase, which induces lipid ...
