May 18, 2024. The upgrading of farm biogas to biomethane/bio-CNG offers great bioeconomic potential to replace fossil fuels such as diesel or natural gas in agriculture. As part of the EU project RES4LIVE (Energy Smart Livestock Farming towards Zero Fossil Fuel Consumption), a pilot plant for upgrading biogas to biomethane/CNG and for refueling series tractors with methane engine has been designed for the first time. It can be used decentralized and self-sufficiently on a farm. This achievement is now listed as an excellent key innovation on the European Commission’s Innovation Radar Platform.
The bio-CNG pilot plant is the result of intensive research collaboration as part of the RES4LIVE project, which aims to make animal husbandry at various European locations energy self-sufficient and fossil-free. The plant was built on the site of the agricultural project partner Lehr- und Versuchsanstalt für Tierzucht und Tierhaltung e.V. in Groß Kreutz and processes the farm’s own biogas into biomethane/bio-CNG, thus enabling a complete replacement of fossil fuels for mobile drives in agriculture.
The innovative complete system was made commercially available for the first time in the 10-35 Nm3 size in a joint development with the machine and plant manufacturer BioG GmbH. This was achieved through innovative simplification steps such as 2-in-1 hybrid compression, single-stage hollow fibre membrane treatment and an open frame design with greatly reduced hazardous areas. Permanent operation of the refuelling station and the farm tractor converted to gas operation is planned beyond the project lifetime as part of the Leibniz Innovation Farm for Sustainable Bioeconomy (InnoHof) for commercial, teaching and demonstration purposes.
“We are delighted that one of our innovations has been analyzed by the European Commission’s Innovation Radar and recognized as an important step towards the defossilisation of agriculture,” said Prof. Thomas Amon, WP Leader and project manager at the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB), one of the 17 RES4LIVE project partners.
The Bio-CNG plant was categorised as “Tech Ready” – i.e. technically mature and ready for use. The potential for creating a new market was also rated as “high”.
The RES4LIVE project shows that the utilisation of biogas in agriculture is not only economically viable but also environmentally friendly. By integrating bio-CNG technologies, agricultural businesses can not only reduce their energy costs in the long term but also make an important contribution to climate protection.
