Who we are

We are an innovative technology start-up company aiming to develop commercially viable and disruptive solutions for utility-scale energy storage, grid balancing, and carbon reuse.

Our proprietary process converts low-cost and stranded electricity and carbon dioxide into pipeline-grade renewable gas for direct injection into the existing natural gas grid, a conversion process known as “power-to-gas”.

The core of our power-to-gas system is a selectively evolved microorganism –a methanogenic archaea– that excels through unprecedented catalytic ability and industrial robustness. The technical advantages of this biocatalyst enable our technology to operate at lower capital and operating costs and with greater flexibility than conventional thermochemical methanation processes.

Our history

Research and development at University of Chicago, USA

Our story starts in 2006 with basic research and development activities performed in Professor Laurens Mets’ laboratory at the University of Chicago.

Pre-commercial trial at Aarhus University, Denmark

In 2011, first field trials with raw biogas at a brewery digester in St. Louis, MO, Electrochaea LLC demonstrated that the technology was compatible with untreated industrial biogas sources. A subsequent pre-commercial field trial demonstrated scalability in a 10,000 L reactor at Aarhus University’s Biogas Research Center in Foulum, Denmark. This trial was partially funded by the Danish Energy Agency and supported by Aarhus University, E.ON, Erdgas Zürich, EWZ and NEAS Energy.

Commercial-scale trial in Copenhagen, Denmark

Following completion of the Foulum project, Electrochaea LLC and a group of German and Swiss investors, founded and financed Electrochaea GmbH in 2014.
In the same year, Electrochaea received funding from Energinet.dk to design, build and operate the BioCat Project: a 1 MW commercial-scale field trial at a wastewater treatment plant outside Copenhagen, Denmark. This project is operated by Electrochaea and its BioCat project partners Hydrogenics, Audi, HMN Gashandel, NEAS Energy and BIOFOS. The BioCat Project began commissioning in early 2016 and provides an operating demonstration plant for Electrochaea and its partners. It will bring revenues from the sale of renewable natural gas in Denmark, and decarbonize the Danish gas grid.

Grid-scale plant in Hungary

Established in 2016, Power-to-Gas Hungary Kft. is building the world's first grid-scale power-to-gas plant with a power consumption of up to 10 megawatts, in partnership with MVM Group and Electrochaea GmbH. The plant will be located in Hungary. For this purpose, local research and development activities have been performed in cooperation with Hungarian professionals, and a power-to-gas prototype will be delivered and operated in early 2018.

Power-to-Gas Hungary Kft. employs a power-to-gas technology based on biological methanation that is unique in the world and was developed by Electrochaea.

A proprietary biocatalyst converts low-cost and stranded electricity from renewable energy sources and carbon dioxide into pipeline-grade renewable gas. The core of the system is a selectively evolved microorganism – a methanogenic archaea. The produced biomethane can be stored and directly injected into the existing natural gas grid.

The foundations of the technology were established at the University of Chicago. Electrochaea is successfully operating a grid-scale plant with a power consumption of 1 MW in Denmark since April 2016. Further plants in Switzerland and USA are under construction. power-to-gas system design
