DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.

Naysayer Alert – the hydrogen red herring

My Electric Car

The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. Nonetheless, hydrogen fuel cell cars are, like pure battery powered cars, classed as Zero Emission Vehicles (ZEV). 2018) Where Are We Heading With Electric Vehicles? Whitehead, J., & Washington, S.
