UK-based Advanced Biofuel Solutions Ltd (ABSL) has announced that it has successfully produced carbon negative biomethane from the 22 gigawatt hour (GWh) waste-to-syngas line at its demonstration plant in Swindon.
To achieve this, the company used its patented RadGas technology, which combines a gasifier, electric arc furnace and waste heat boiler in a process that converts household waste and biomass residues into a synthesis gas or ‘syngas’ free of tars and particulates.
The syngas can then be used as a feedstock for catalytic conversion into a range of biofuels and a pure stream of carbon dioxide (CO2). These can be used instead of fossil fuels in hard-to-abate sectors such as industrial heating or the production of sustainable air fuel (SAF).
