We had earlier reported on some of the work at Palo Alto, but the following excerpts capture the distilled essence of it:
"To address this challenge, we are developing technologies capable of capturing CO2 at atmospheric concentrations and delivering it at high concentrations. This concentrated CO2 can then be combined with hydrogen from electrolysis (of water - JtM) to form liquid hydrocarbon fuel... "
"PARC continues to research and develop high-pressure, pH-controlled prototype optimized for CO2 concentration. Further research will combine this air capture technique with thermocatalytic conversion of CO2 or with reverse water-gas shift reaction and Fischer-Tropsch for “carbon neutral” hydrocarbon fuels synthesis."
