EU Innovation Council invests €17.5 Million in Electrochaea’s Power-to-Methane technology

Electrochaea ́s power-to-gas technology receives funding from the European Innovation Council (EIC), confirming that their market-ready innovations make an important contribution to the goals of the European Green Deal and the UN agenda for sustainable development.
Based on biocatalysis, Electrochaea offers a multiple nationally and internationally patented key power-to-gas technology, which cost-effectively recycles CO2 and at the same time produces CO2-neutral methane from excess electrical energy that can be stored and used as required.


In total, more than 2,000 European companies applied for the “EIC Accelerator” pilot program. Electrochaea is one of only 64 selected start-ups and medium-sized companies supported bythe Councilwith their projects. The EIC Accelerator program is part of the EU research and innovation program”Horizon2020″. It is aimed at entrepreneurs and SMEs that can apply for grants or mixed financing from grants and equity support. Since this year, around €300 million are available for submissions that promote the European Green Deal. Electrochaea fulfils this requirement in three ways: the long-term storage of renewable energy, production of biomethane, and reduction of the carbon footprint by using CO2 emitted by various industrial sources.

“We are proud to be one of the few selected funding recipients of the EIC. For us, this funding commitment is also a crucial strategic statement,” explains Dr. Doris Hafenbradl, CTO of Electrochaea. “In its rationale, the European Innovation Council confirms for the first time and in all clarity that Europe needs sustainable storage solutions for renewable energy sources and that green gas is indispensable for a sustainable, reliable and comprehensive energy supply”.

The EU funds will be used for the so-called scale-up, the development of the technology from existing pilot plants to commercially scaled plants. With the equity investment, Electrochaea will construct a fully operational 10 to 20 MW plant. The outcome is that customers will benefit: by scaling up and building a sample plant, the risk for commercial projects will be minimized and Electrochaea will be able to offer reliable and highly efficient standardized plants. “The additional financial resources will help us to apply the potential of biological methanation even faster on a commercial scale,” says Hafenbradl. “The European Innovation Council explicitly recognizes the expertise, diversity and motivation of our team as important factors in our success story in constructing industrial pilot plants and forming strategic partnerships with key players”.

Harald Beschid (COO), Doris Hafenbradl (CTO and Managing Director) and Birgit Lewandowski (Director Development) of Electrochaea are pleased about the investment of the European Innovation Council and consider it as a strong political signal. (© Electrochaea GmbH, 2020)

Electrochaea injects biomethane into Danish natural gas grid

World's biggest biological power-to-gas plant

feeds biomethane into Danish natural gas grid


Renewable methane, produced by the world’s largest biological power-to-gas plant, was injected for the first time into the Danish natural gas grid on September 24, 2019 near Copenhagen, Denmark. Using Electrochaea’s patented power-to-gas technology, the energy in green electricity can be stored in the natural gas grid for later use. Microorganisms, called archaea, are the key to the technology; the archaea exclusively synthesize methane, the key component of natural gas, from carbon dioxide (CO2) and hydrogen. At the Danish plant, the archaea make methane by combining CO2 from a nearby wastewater treatment plant with hydrogen produced by an on-site electrolyzer, which uses electricity to split water into hydrogen and oxygen. With a power consumption of one megawatt, the plant has the capacity to inject up to 31 SCFM of biomethane (1200 m3 per day) into the natural gas grid at the same time preventing the release of 800 tons of CO2 per year. The gas produced contains more than 98% methane and less than 1% hydrogen and CO2, exceeding the requirements for gas grid injection in Denmark. This high gas quality also exceeds the injection criteria in other relevant markets, such as Germany and California. The plant was built and operated with the support of the joint BioCat project (, funded by the Energy Technology Development and Demonstration Program (EUDP) of the Danish Energy Agency. The main goals of project are to develop an efficient and marketable solution for the storage of wind energy, which is needed to balance energy supply and demand in situations where variable renewable energy sources, such as wind power, are dominant. The interest in storage solutions for renewable energy is particularly high in Denmark. The country’s goal is to be independent of fossil fuels and to have 100% renewable energy for all uses including transportation by 2050. By 2030, Denmark wants to produce 70% less CO2 compared to 1990 emissions.
