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.

Innovative prototype development and operations in Vértes Power Plant, Hungary

Established in 2016, Power-to-Gas Hungary Kft. has developed the most innovative lab scale power-to-gas prototype from Europe. The prototype is operated since 2018 in Vértes Power Plant. Numerous scientific papers have been published about the operations experience. Power-to-Gas Hungary Kft. has been awarded with TOP 10 Innovation Award of Hungary in 2019, and has also initiated and organised the 1st Hungarian Power-to-Gas Conference at the Hungarian Academy of Sciences in 2019, in partnership with Budapest University of Technology and Economics, Budapest Corvinus University and Hungarian Academy of Sciences Center for Energy Research.

Grid-scale plant in Hungary

Power-to-Gas Hungary Kft. is aiming to build 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 have been performed in cooperation with Hungarian professionals and academic institutions. Detailed financial and technical planning, as well as local site selection and business development activities are currently in focus.

Management

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
