BIOGAS FUTURE BIOGAS INAUGURATE FIRST TRIOGEN ORC IN THE UK A showcase of successful Anglo-Dutch business cooperation as symbolically demonstrated by Margriet Leemhuis (centre) deputy Dutch Ambassador to the UK together Philipp Lukas, CEO, Future Biogas (left) and Henning von Barsewisch, CEO, Triogen during the ribbon cutting ceremony. With the market entry in the UK, Triogen is now active in eleven countries across Europe. Bioenergy International No 83, 7-2015 37 ORIGINALLY COMMISSIONED IN 2013 by Future Biogas Ltd, the Oak Grove Renewables site is a 2 MWe biogas power plant in Scottow, Norfolk. Future Biogas was set up in 2009 up to develop, construct and operate biogas plants across the UK. Supplied by German turnkey biogas technology providers, Agraferm Technologies AG, the Oak Grove plant utilises around 35 000 tonnes per annum of maize and grass silage. This is sourced from Aylsham Growers Renewables Ltd (AGRL), a group of local farmers all within a 12 km radius of the plant. The digestate is put through a press screw from German FAN Seperator GmbH before used as a bio-fertiliser. Residual heat to power Future Biogas has currently eight biogas plants including a biomethane to-grid facility in operation and has another two projects under construction. The plants use a range of biomass feedstock sourced in partnership with local farmers. – We see that more can be done to optimize performance of the biogas plants, commented Philipp Lukas, CEO of Future Biogas and Board Member of the Anaerobic Digestion & Bioresources Association (ADBA). Lukas was referring to utilizing the residual heat from the gas-fired engine, a challenge considering the rural location of the plant with no obvious heat sink such as space heating in the vicinity. Applying the high-temperature organic rankine cycle (ORC) technology from Dutch providers Triogen, the residual heat from the engine is converted into electricity. The plant is expected to increase its electrical output by up to 10 percent without any additional input material. – We are pleased to work with Triogen as they offer a mature solution with long track record and very high efficiency levels. This allows us to build an attractive business case while reducing the overall cost of generating power from this site, said a notably pleased Lukas. The celebratory event also featured a discussion by industry experts on “the future of efficiency and cost reduction in AD”. – Bioenergy based energy generation is an important contributor to achieving the UK’s emissions targets. Government and industry need to work together to reduce the cost of bioenergy based energy generation. I believe that significant cost reductions are possible and turning heat into electricity, as demonstrated by Oak Grove and Triogen, is an important piece to this puzzle. We encourage the government to continue the dialogue with this industry to realize its potential, said Charlotte Morton, CEO of ADBA in her address. – Our technology is a contribution to making decentralized generation more affordable which will be an important factor for reaching the politically agreed emission targets. Converting the excess heat available from a biogas plant into electricity reduces the cost of producing power from the plant by 5 percent. Thus, we offer a key technology to making biogas more cost effective, said Henning von Barsewisch, CEO, Triogen.
