ABSL successfully produces syngas from waste-based UK demo plant

In the UK, Advanced Biofuel Solutions Ltd (ABSL) announced successful first production from the 22 GWh waste-to-syngas line at its demonstration plant in Swindon, using its patented RadGas technology.

RadGas combines a gasifier, electric arc furnace and waste heat boiler in a highly efficient, reliable process that converts household waste and biomass residues into a synthesis gas or “syngas” which is free of tars and particulates. Crucially, that syngas is clean enough to be used as a direct feedstock for catalytic conversion into a range of biofuels and a pure stream of carbon dioxide. The biofuels can then be used as an alternative for fossil fuels in hard-to-abate sectors where electrification is a challenge, such as industrial heating or the production of sustainable air fuel (SAF).  When the carbon dioxide is transferred and stored in sequestration infrastructure, the process generates negative emissions essential for reaching Net Zero.

ABSL’s Swindon plant is configured to convert the clean syngas first into biohydrogen and then into biomethane, with the flexibility to vary the proportions over time. The final stage is low-cost carbon dioxide capture, resulting in an overall process that is carbon negative. Commercial offtake agreements are in place for all the inputs and outputs in the plant at Swindon, with the biomethane exported directly to the gas grid.
