Gasrec, the UK’s first commercial producer of liquid biomethane fuel; BOC, a member of the global gases and engineering Linde Group; and SITA UK, one of the UK’s leading recycling and waste management companies, have begun production of liquid biomethane (LBM) fuel from the Gasrec plant at SITA UK’s Albury landfill site in Surrey, UK.
The Albury plant will produce approximately 5,000 tonnes of LBM per year, sufficient to fuel up to 150 heavy-duty or up to 500 light-duty vehicles, depending on their fuel source (i.e. dedicated gas or dual fuel), mileage, load and duty.
Project life for the Albury landfill LBM work is 15 years. Organic degradation produces around 2,200 m3/hour of landfill gas (LFG), about 50% of which is methane (CH4) with the balance being nitrogen and CO2. The Gasrec technology will recover more than 85% of the methane contained in the raw LFG.
The Gasrec process cleans the landfill gas of all impurities before methane is separated and liquefied to create LBM for vehicle fuel. The liquefaction technology for landfill applications is provided under an exclusive UK agreement with BOC’s parent, The Linde Group. BOC provides plant operation and maintenance services as well as risk management and engineering expertise.
LBM not only offers a renewable alternative to fossil fuels, but also burns more cleanly and quietly than diesel, with a 90% reduction in PM10 particulate, a 60% reduction in NOx, a 50% reduction in SO2 and a 30% reduction in noise.
The use of the LBM as a fuel substitute for fossil diesel or gasoline will result in carbon dioxide savings in the region of 70% on a full lifecycle basis, according to Gasrec. All vehicles that can operate on CNG (compressed natural gas) or LNG (liquefied natural gas) can run on LBM, however LBM offers a reduction in CO2 emissions which is twice that of natural gas, according to the JEC2006 and CONCAWE lifecycle studies.
The initial target for the use of LBM is commercial vehicles operating in the haulage and waste management sectors.
Gasrec has signed an agreement with the Hardstaff Group, one of the largest LNG bulk transporters in the UK, to manage transport logistics and fuel transportation from Albury. The haulage trucks use Hardstaff’s dual fuel system running entirely on LBM.
We have produced electricity from landfill gas for many years but we believe there is a big future for generating fuel from waste. We have another waste-to-fuel project in Hong Kong and have been keen to see this type of technology take off in the UK. We are keen to expand our relationship with Gasrec to cover other types of waste recovery facilities.—Stuart Hayward-Higham, New Markets Business Development Manager at SITA UK
The official launch of the Albury plant will take place on 24 June.
