A CO2-to-fuel process demonstrated

Scientists at Carbon Sciences Inc. (Santa Barbara, Calif.; www.carbonsciences.com) have successfully demonstrated a CO2-to-fuel process that proceeds under mild conditions using fluegas emissions as a carbon dioxide source and brackish water as a hydrogen source. The modular, three-step process is…
