The consequences of the 2018 and 2019 drought are immediately apparent in agriculture and forestry. These sectors, especially agriculture, are also part of the solution, as well as being directly affected. Rapeseed oil fuel and biomethane are ready for use in combination with today’s modern engine and exhaust gas treatment concepts. Technology development is hugely important internationally to overcome regional supply problems, for example in developing countries with decentralised production of biofuels. As well as generating valuable by-products for animal feed, the fermentation involved in production also encompasses a refining process that significantly boosts the fertilising effect of the biogas slurry’s nitrogen content and enriches the soil with carbon. Progress needs to be made on market access and acceptance levels in the world of politics and within agriculture to ensure that sustainable and greenhouse-gas-optimised biofuels can contribute to climate protection.
The presentations in the “Biofuels in Agriculture and Forestry” forum at the 17th International Conference will focus in particular on addressing market entry strategies, drawing on the example of biomethane tractors from agricultural machinery manufacturer New-Holland, along with presentation of extensive practical experience with a gas tractor tested with biomethane for over 1,000 hours at Rostock University. The issue of fuel detection arises with rapeseed oil fuel, as elucidated here for a John Deere Stage 5 engine. A report on practical experience with growing and processing arable feedstocks to generate high-quality fuel for use in a vegetable-oil-fired tractor will round off this forum.
