Methods, systems and apparatus for a closed-loop process utilizing metal catalysts for the clean production of hydrogen gas from landfill gas and biomass.
Hydrogen is considered the fuel of the future due to its environmental advantages over conventional fossil fuels. U.S. production of hydrogen generates billions of dollars in sales each year. Current hydrogen production methods make use of fossil fuels, which have the benefit of relatively low cost with an existing infrastructure for delivery and distribution. However, fossil fuels are finite, and are the main source of air pollution causing considerable damage to the environment. In contrast, energy sources such as landfill gas and biomass are considered renewable, contain a large quantity of hydrogen and can be used as a carbon-neutral fuel. Current reformation techniques for producing hydrogen from landfill gas face two challenges: the presence of harmful impurities, such as sulfur, nitrogen and silicon-containing compounds, and the source’s non-uniformity. The disclosed process improves upon the deficiencies of the existing technologies by utilizing a closed-loop catalytic process to extract hydrogen from biomass and landfill gas.
UCF researchers have developed a method for producing 99.9% pure hydrogen gas from landfill gas and various forms of biomass (including wood scraps, agricultural waste, etc.). This closed-loop process significantly reduces harmful emissions by re-using byproducts produced in earlier steps to power subsequent ones. It also incorporates in situ produced bio-carbon as a scrubber material in order to further reduce any environmental impact. The process’s byproducts can then be sold as soil enhancers.
