U. Mich study: natural-gas-based ICE, BEV and FCV all show promise for environmental benefits relative to conventional ICE

Green Car Congress

Qiang Dai and Christian Lastoskie found that BEVs and FCVs in particular offer significant reductions in greenhouse gas emissions, especially if carbon capture and sequestration (CCS) technologies are implemented at the fuel conversion facilities. The FCV has an overall energy conversion efficiency about 30%. —Dai and Lastoskie.

Spatially explicit life cycle assessment of 5 sun-to-wheels pathways finds photovoltaic electricity and BEVs offer land-efficient and low-carbon transportation

Green Car Congress

A new spatially-explicit life cycle assessment of five different “sun-to-wheels” conversion pathways—ethanol from corn or switchgrass for internal combustion vehicles (ICVs); electricity from corn or switchgrass for battery-electric vehicles (BEVs); and photovoltaic electricity for BEVs—found a strong case for PV BEVs.
