The project is implemented within the European Innovation Partnership (EIP) and is funded by the European Agricultural Fund for Rural Development. The aim is to develop a system for production of biomethane (vehicle fuel quality) with ash filter technology at farm level. Ash filter is a simple technology that has the potential to be cost-effective for small-scale vehicle gas production, for example at biogas plants on farm level and smaller wastewater treatment plants. The project is ongoing during the years 2020-2022 and is being implemented by RISE (project manager), Västra Götalandsregionen Naturbruksförvaltningen and Nordic Gas Solutions.
By upgrading biogas, the gas gets a higher value compared to today’s normal use for cogeneration of electricity and heat. In addition, the farmer can use the gas to offset the farms vehicle fuel costs. Biogas as a vehicle fuel leads to significant environmental benefits by replacing fossil fuels. Furthermore, small-scale production of vehicle fuel quality biogas (biomethane) contributes to increased energy security by making fuel production more decentralized.
The project has two final goals:
The system with a front-end-loader-handled ash filter will be installed at Naturbruksskolan Sötåsens farm based biogas plant and the produced biomethane will be used to refuel the farm’s biogas tractor and biogas cars.
The project includes designing, manufacturing and installing the ash filter system as well as designing technical systems for the sale of the gas and looking at a concept for ash handling. Furthermore, various possible company formations will be investigated to find solutions to the challenges of accessing the market for vehicle gas from a small-scale biogas plant and to be able to ensure economical, efficient and sustainable ash management.
