Company profile
researched Aug 2026Electrochaea is a Power-to-Gas (P2G) technology company that has developed and patented a biomethanation process using methanogenic archaea to convert green hydrogen and carbon dioxide into low-carbon, grid-quality e-methane. The company positions the technology for commercial-scale deployment, stating a CO2 conversion efficiency of 98.5% and the ability to process untreated CO2 from any source under mild process conditions and with high tolerance to contaminants in the CO2 feed gas.
The technology is offered as a modular, scalable system with load-following capability. Electrochaea states that its modular units can be deployed at 100+ MWe scale to produce approximately 400 GWh of e-methane. The resulting gas can be injected directly into gas grids, sold to third-party consumers, used on site to power operations, or liquefied into eLNG for use as a liquid fuel. Applications are framed around emissions reduction, capture of methane slip, reduction of carbon tax liabilities and diversification of revenue streams for energy producers, utilities and industrial operators.
Alongside its research and engineering staff, the company maintains techno-commercial, project management, sales and sustainability functions. Services described include in-house techno-economic and feasibility assessments, a qualified network of engineering partners for installation, flexible technology transfer and licensing agreements, and on-site commissioning and operator training.
Business model
Electrochaea commercializes its biomethanation process through technology transfer and licensing agreements rather than owning and operating plants itself, supplying licensed on-site technology together with feasibility assessment, engineering partner coordination, commissioning and operator training. An example is a five-year technology transfer and licensing agreement signed with Hitachi in 2024.
The company offers flexible technology transfer and licensing agreements for its patented biomethanation technology, supported by in-house techno-economic and feasibility assessments and on-site commissioning and operator training services.
Traction
In November 2024 Electrochaea signed a five-year technology transfer and licensing agreement with Hitachi, which is to deploy the technology at what is described as Japan's first biomethanation plant. In February 2025 Electrochaea and Baker Hughes finalized a basic engineering and design package (BEDP) combining Electrochaea's biomethanation technology with Baker Hughes' carbon capture solutions to bring commercial-scale biomethanation to market. In December 2025 the company joined the e-NG Coalition.
Latest developments
Recent company announcements include joining the e-NG Coalition (December 2025), the completion with Baker Hughes of the basic engineering and design package integrating Electrochaea's biomethanation technology with Baker Hughes' carbon capture solutions (February 2025), an op-ed by Dr Doris Hafenbradl in Project Syndicate on public guarantees for European green industry (December 2024), and a five-year technology transfer and licensing agreement with Hitachi (November 2024).

Market position
The company presents itself as a provider of commercial-scale biomethanation technology for e-methane production, with licensing agreements involving industrial partners including Baker Hughes and Hitachi, and membership of the e-NG Coalition, an alliance promoting electric natural gas.
Electrochaea emphasizes its patented archaea strain and self-replicating biochemical process, 98.5% CO2 conversion efficiency, tolerance to untreated and contaminated CO2 feed gas, mild operating conditions, modular unlimited scalability with load-following ability, demonstrated industrial-scale operation, and an in-house techno-commercial team supporting licensees beyond the core technology.
Technology
The core technology is a patented, self-replicating biochemical process in which proprietary methanogenic archaea convert green hydrogen and CO2 into methane. Electrochaea reports 98.5% CO2 conversion efficiency, operation at mild process conditions, high tolerance to contaminants in the CO2 feed gas, the ability to convert untreated CO2 from any source, excellent load-following capability, and modular scalability up to 100+ MWe producing roughly 400 GWh of e-methane. The company states the process has been proven at industrial scale, and the output is certifiable, pipeline-quality gas suitable for direct grid injection or liquefaction into eLNG.
Go-to-market
Electrochaea markets through licensing and technology transfer deals with large industrial and energy partners, combining its biomethanation process with partner capabilities such as Baker Hughes' carbon capture solutions, and works through a qualified network of engineering partners for installation. It also participates in industry advocacy, having joined the e-NG Coalition, and engages in public policy commentary.
Energy producers, gas utilities and industrial operators with CO2 emission or methane slip streams that seek certified low-carbon gas, grid injection opportunities, on-site low-carbon energy supply or reduced carbon tax exposure. Announced counterparties include Baker Hughes and Hitachi.
Geography
The company's licensed technology is aimed at gas grids worldwide, with disclosed activity including a licensing agreement covering deployment in Japan and commentary on European green industry policy.
