Hybrid hydrogen-carbon process is a proposed method for increasing the efficiency of gasification and other biomass to liquids technologies. By feeding hydrogen produced from renewable sources, particularly solar, into the gasification process you reduce the CO₂ produced and can possibly triple the amount of liquid fuel produced per ton of biomass. The idea is to have biomass be purely a source of carbon for liquid hydrocarbons.^[1]

Products

Advantages

Commercialization status

• This is still in the proposal and design stage.
• A patent application has been submitted.^[1]

Sustainability and Environmental Concerns

• Would use substantially less land to produce the biomass, as more liquid fuel could be produced from less biomass.

Societal Impacts

Feedstocks

Feedstocks that can be used for gasification include

• Any organic material - Examples include agricultural wastes, hazardous organic wastes, and industrial wastes.

News

• Purdue University unveils biofuels process "to meet all U.S. transportation needs", 14 March 2007 from Biofuel Review. An improved version of a biomass-to-liquids technology, the new approach, called a hybrid hydrogen-carbon process, adds hydrogen from a "carbon-free" energy source, such as solar or nuclear power, during gasification. "Adding hydrogen during this step suppresses the formation of carbon dioxide and increases the efficiency of the process, making it possible to produce three times the volume of biofuels from the same quantity of biomass".
