Commercial aircraft rely on liquid hydrocarbon fuels. Short-range all-electric aircraft have promise to reduce environmental impacts while remaining cost-competitive; however, they will require significant battery improvements.doi:10.1038/s41893-019-0233-2Viswanathan, Venkatasubramanian...
Using alternative fuels such as hydrogen in electrified propulsion systems presents one potential approach for reducing aircraft emissions. The development
Firefighters also have been shoring up protections around any remaining structures in the evacuation zones and clearing away dry brush and dousing hot spots. Crews also are preparing for a worst-case scenario in which extreme winds might prevent the use of firefighting aircraft, suc...
Using alternative fuels such as hydrogen in electrified propulsion systems presents one potential approach for reducing aircraft emissions. The development of a safe hydrogen storage with acceptable energy densities introduces an essential challenge. Metal hydrides enable inherently safe, reliable, and sustain...
