Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

C and pressures above 200 bar to be facile, and therefore the capital cost of plant and equipment is substantial. Modern H-B plants produce ammonia at an energy cost of at least 8 MWh tonne -1. The reaction between N 2 and H 2 requires temperatures in excess of 400 ?C Ammonia production is currently responsible for ~1.0% Generation 2.

NREL study finds most depot charging could accomodate short-haul heavy-duty electric trucks without upgrades

Green Car Congress

Commercial heavy-duty trucking operations are motivated to reduce operating costs. A 2020 BloombergNEF report shows that fuel costs for trucks make up more than half their total cost of ownership. This study shows that charging requirements could be met at power levels in line with current light-duty charging technology (?100
