Reverion and Bilfinger, the international industrial services provider for the process industry, have signed a letter of intent to collaborate in the field of sustainable biogas plants. The aim of the strategic cooperation is to bring Reverion’s innovative technology – a modular power plant based on fuel cells for efficient power generation and energy storage – to the market and to expand it on an industrial scale.
As a unique all-in-one solution, Reverion’s patented technology enables not only efficient power generation from biogas with particularly high electrical efficiency, but also the generation and storage of green hydrogen or synthetic natural gas as well as the cost-effective capture of clean, storable CO2. After completion of the pilot phase, Bilfinger will support the spin-off from the Technical University of Munich in converting existing biogas plants to the new technology with a combination of comprehensive industrial services from various trades.
Volatile renewables require technologies that can balance the grid and store energy. Biogas is already an important part of the energy transition and the only renewable energy source that can provide both secure baseload power and balancing power for intermittent wind and photovoltaics. However, conventional biogas combined heat and power (CHP) plants typically operate with gas engines that have a maximum efficiency of 40 %, offer no storage option, and emit several million tons of CO2 per year. Modern fuel cell systems achieve higher efficiencies of 50-60 %, but due to significantly higher costs do not yet have an economic advantage over gas engines.
Reverion’s skid-based power plants, on the other hand, are designed to increase electrical efficiency up to 80 %. In addition, the power plants can run “backwards” in reversible mode to produce and store green hydrogen or a renewable natural gas substitute in electrolysis mode when there is a temporary surplus of wind and solar power. This multiple use creates a high degree of flexibility and, for the first time, economic superiority despite higher investment costs. By capturing pure CO2 or converting it to natural gas substitute, the entire process becomes significantly carbon negative, enabling low-cost removal of CO2 from the atmosphere.
Upon completion of the pilot phase in 2023, the 100 kW systems will go into series production. According to the letter of intent, multidisciplinary teams from Bilfinger Engineering & Maintenance GmbH and Bilfinger Life Science Automation GmbH will support the start-up of the skid production and the conversion of existing biogas plants to the innovative technology. The services include pipeline construction, installation of process technology components, production of special components and skid assemblies, as well as instrumentation and electrical engineering.
Bilfinger supports customers in the process industry with a comprehensive portfolio of services to increase the efficiency and sustainability of their plants. From established technologies such as energy efficiency, hydropower or wind power to newer areas such as Carbon Capture, Utilization and Storage (CCUS) or green hydrogen solutions, Bilfinger is constantly developing its services to optimally support its customers along the entire value chain of their plants and to deliver solutions for a more sustainable industry.
