JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern

Green Car Congress

The applications, i.e. technologies, of particular concern as a result are electric vehicles, wind and solar energy, and lighting. The researchers investigated the sensitivity to these sources of uncertainty in depth for hybrid and electric vehicles and lighting.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The shipping containers, which house a Frankenstein-like assortment of machine parts—motors repurposed from Volvo truck engines, giant tanks of compressed air, huge silos of piping hot sand—are produced by a company called Cheesecake Energy. The motor drives a piston that compresses air, which gets hot as it’s compressed.

Study Finds Bioelectricity Better Option Than Liquid Biofuels for Transportation Output and GHG Emissions

Green Car Congress

With BEVs and ICVs of similar size, one can travel farther on biomass grown on a hectare of land when it is converted to electricity than when it is converted to ethanol.For this case, the gross transportation output per hectare is 85% greater for bioelectricity than cellulosic ethanol.
