Q Power and Convion Collaborate to Transform Biogas Plants with High-Efficiency Methanation and Hydrogen Technology, for Doubling the Output of Biogas plants

Press release 12.10.2023

Q Power, a pioneer in the development of synthetic methane technologies, and Convion, a leading provider of solid oxide electrolyzer and fuel cell technology, have joined forces to develop an efficient concept for biogas plants to maximize the value of their assets. This collaboration harnesses the power of Q Power’s methanation technology and Convion’s hydrogen production and fuel cell technology to address the growing need for biogas upgrading. The jointly developed concept will be modular and fully scalable for biogas production facilities starting from below 1MW.

Biogas storage

The growing demand for replacing imported natural gas with renewable alternatives is driven by an imperative to decarbonize and secure the supply of energy in Finland and globally. For bridging the gap between supply and demand for natural gas in Europe, locally produced biogas is a potent and only partially utilized resource. 

Harnessing the full potential of biogas plants

Biogas upgrading is an important step. Conventionally CO2 is separated from biogas and released into the atmosphere, wasting valuable resources. The partnership between Q Power and Convion aims to revolutionize this process by integrating methanation and hydrogen production technologies into a cohesive concept that maximizes resource utilization and the amount of produced biogas.

To fully capture the value of a biogas resource, carbon dioxide (CO2) contained in biogas can be converted to methane (CH4) by methanation, using renewable hydrogen (H2) produced by electrolysis and, as a result, significantly increasing the production of renewable methane. An individual producer can even double the amount of gas they produce. Given the intermittent nature of renewable power sources, Convion’s electrolyzers have the capability to switch into a power generation mode, utilizing biogas directly as a fuel, when grid electricity is expensive. Bi-directional operability of the system offers maximum flexibility and alternative revenue streams for the plant owners to optimize their operations.

Combining two cutting-edge technologies for superior efficiency

Convion’s solid oxide system technology offers several advantages for the concept. Solid oxide fuel cell (SOFC) and electrolyzer (SOEC) systems are renowned for their unparalleled efficiency, making them the top choice for power conversion and hydrogen production across different scales. Due to the high operating temperature, hydrocarbon fuels such as biogas can be used directly as fuel for power generation at 60% net electrical efficiency, and by-product heat is readily available for capture and utilization. The electrical efficiency of steam electrolysis is over 85%. In Convion’s bi-directional system platform, the two use-cases converge and offer a customer ultimate flexibility for plant optimization.

Q Power brings over a decade of research and development experience in the efficient production of carbon-neutral synthetic fuels. Their biocatalytic methanation process, powered by unique microbes originally isolated from Finnish marshland, is the most energy-efficient solid-state methanation technology on the market, with a remarkable plant efficiency of 81% (from hydrogen to methane), and on top of this excess heat can be utilized. This modular technology can be seamlessly scaled from small-scale to industrial scale. The Q Power reactor design ensures efficient gas transfer and biological efficiency without the need for heating, pressurization, or constant fluid pumping.
