Abstract
Described are technologies including methods and systems that can be used to produce carbon-neutral and/or carbon-negative renewable gaseous fuel from various organic wastes. In some implementations, such renewable fuel can be used in vehicles that transport the wastes from the waste generators to centralized waste disposal locations and/or manage the wastes at the waste disposal locations.
Claims20
A method for producing transportation fuel, the method comprising:
- heating, in a thermal conversion process, a solid feed material in the absence of oxygen to liberate gas and residual carbonaceous solid, the gas having a calorific value;
- utilizing a portion of the liberated gas to produce hydrogen for use as a transportation fuel;
- utilizing the remaining portion of the liberated gas to produce renewable heat and electricity to reduce an overall carbon intensity of the transportation fuel production process;
- and
- capturing the residual carbonaceous solid as a waste product for landfill disposal or use as a fuel, soil amendment, concrete additive, or various carbon applications.
A system for producing transportation fuel from carbonaceous waste for vehicles that transport the waste to and manage the wastes in landfills and other centralized waste management locations, the system comprising:
- a thermal conversion system configured to heat a solid waste feed material in the absence of oxygen to (a) liberate gas that comprises hydrogen and other constituents having a calorific value from the solid and (b) produce a residual carbonaceous solid;
- a preheating system that uses excess heat from the thermal conversion system configured to remove moisture, increase waste temperature, and/or reduce the heat required in the thermal conversion process;
- a gas cooling and/or cleaning system configured to treat liberated volatile gasses from the gas production unit to remove soot particles and/or gasses that condense into liquids at ambient temperatures to produce a biogas;
- and
- a high purity hydrogen production system configured to produce, from the biogas, a gas product comprising greater than 99% hydrogen and a residual tail gas comprising removed non-hydrogen gasses in the biogas.
