Biomethane and its applications is a crucial topic for biogas’s future development across Europe. As such it has been accorded a half-day segment at an upcoming Biogaz Europe conference, to be held on October 25-26 in Nantes, France. The afternoon session with start off with an overview of the status of biomethane today in Europe from Andy Bull, Project Co-Ordinator of the IEE project, BioMethane Regions. The French biomethane context for direct injection and for transport will be given by GRDF and the French Natural Gas Vehicle Association (AFGNV).
Additionally, four innovative case studies will exemplify the benefits of biomethane for transport (from Sweden, UK, Austria and France).
Valtra Tractors (SE) : The Valtra N101 dual-fuel tractor has 110 horsepower and is intended as an all-purpose tractor for farms, municipalities and contractors that have the possibility of refuelling with biomethane while working. Without making any changes to the original diesel engine, 70 to 80 percent of power is generated by biomethane. The dual-fuel engine functions like a diesel engine and performs the same whether operating on dual-fuel or just diesel. The gas is injected with the intake air, and combustion occurs when a small amount of diesel fuel is injected into the cylinder. If biomethane is not available, the engine can run completely on diesel fuel.
Adnams Brewery (UK) : Adnams Bio Energy Limited has constructed and is now commissioning a groundbreaking anaerobic digestion (AD) plant, which will be the first in the UK to use brewery and local food waste to produce biomethane for direct injection into the national gas grid (in partnership with British Gas and the National Grid) as well as providing gas for use as a vehicle fuel. In the future the facility will produce enough renewable gas to power the Adnams brewery and run its fleet of lorries, while still leaving up to 60 per cent of the output for injection into the National Grid.
Fuchsn’hof, Austria (AT) : Austria’s first biogas feeding-plant has been operating in Upper Austria since June 2005. This pilot project supplies the existing natural gas grid with biogas up-graded to natural gas quality. Fuchsn’Hof, an existing biogas plant that used biogas for generation of electricity, now serves as a gas production plant. The substrate consists of a mixture of manure from 10,500 hens and 50 breeding pigs.
BioEnergie de la Brie (FR) : BioEnergie de la Brie is a project under development which anticipates to utilise a blend of cattle slurry, vegetable, cheese production wastes and cereal residues to produce and upgrade biogas to biomethane quality for direct injection to the gas grid.
