Currently, most hydrogen is produced via the steam reforming of natural gas, hydrocarbons and coal. WGS is an endothermic process typically carried out in industry at high temperatures (about 350 °C) with either an iron oxide- or copper-based catalyst to achieve almost complete CO conversion.

The concept’s key feature is the use of high-temperature heat from a solar concentrating tower to drive the chemical process of converting biomass to a biofuel, obtaining a near-complete utilization of carbon atoms in the biomass. Energy conversion efficiency (%). Total cost estimate (2001$/GJ), inc. CO 2 charge @ $100/tC.

Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. Three more points: Both reports match up well with previous studies. The GREET 1.6
