ABSL is developing its first large-scale industrial plant, situated in the Protos energy park near Ellesmere Port in Cheshire.

The facility will be able to produce biohydrogen and biomethane, while capturing the CO2 with no polluting emissions to air and no particulate or dioxin emissions.

ABSL have announced the signing of a Joint Development Agreement with Greenergy to develop, construct and operate up to five waste-based biofuel plants in the UK.

Using ABSL’s proven and patented RadGas technology, the first plant in Protos will convert 133,000 tonnes of waste into biomethane or biohydrogen for use in HGVs or buses.

Together, the five plants would replace millions of litres of fossil petrol and diesel used in transport fuels, saving 800,000 tonnes of carbon dioxide per year, with the output of the plants sufficient to power 5,000 HGVs.

The fuels will qualify as development fuels under the UK’s Renewable Transport Fuel Obligation (RTFO).

The RadGas plants are able to process a wide variety of feedstocks, including household waste, dried biomass residues such as straw, and waste wood.

The feedstock will be sourced from within the UK and processed onsite, being supplied under long term contracts by a mixture of large-scale waste companies, as well as smaller local waste companies, aggregators or brokers.

Each plant will process 133,000 tonnes of waste per year. This equates to the waste output of approx 260,000 households in the UK that would otherwise be incinerated, exported or sent to landfill.




Protos is an energy and resource hub located near Ellesmere Port in the North West of England. It clusters together innovative technologies, connecting energy intensive businesses with sources of low carbon energy.

It is part of the Hynet consortium, HyNet North West, one of the two priority carbon sequestration networks recently announced by the Department for Business, Energy & Industrial Strategy (BEIS).

This offers many options for the CO2 output from the plant captured from the RadGas process, one of the key aspects of our technology.



Petrofac, a leading UK EPC contractor, will manage the build to deliver the plant at Protos.

Front-End Engineering and Design (FEED) is expected to be completed in Q3 2022, with construction and commissioning complete by the end of 2025.

Towards Net Zero

The plants will produce either biomethane or biohydrogen for use in the road transport sector. Both have significant greenhouse gas savings in comparison to traditional road fuels. Achieving net zero requires the replacement of fossil fuels used in transport with sustainable low carbon alternatives – such as biohydrogen.

Our plants process waste through gasification to create biohydrogen, avoiding waste going to landfill or incineration.  Biohydrogen when made by RadGas is attractive because it is cheaper than green hydrogen at the same time as delivering greater greenhouse gas emission savings.

The RadGas process makes a hydrogen rich syngas which contains a high concentration of carbon dioxide.  When separating the fuel from the carbon dioxide, we are naturally left with a clean, high quality stream of carbon dioxide which can either be liquefied or sequestrated, creating negative emissions, which helps to reverse climate change.
