Electrochaea synthesizes low-carbon intensity BioCat Methane from renewable
energy and carbon dioxide using a patented process with ancient archaea as
the biocatalyst.



Electrochaea is commercializing a grid-scale energy solution incorporating modern science and single-celled microorganisms billions of years old. The company converts renewable energy and otherwise climate-harming carbon dioxide into grid-quality BioCat Methane, a renewable synthetic methane that is reliable, practical, and safe for storage and distribution in the existing gas infrastructure. 




Electrochaea’s proprietary energy solution accelerates decarbonization of the gas grid and allows for the efficient and nearly unlimited storage of energy for future use by replacing fossil gas with a clean fuel option.


BioCat Methane


Electrochaea makes a low-carbon intensity synthetic methane from green hydrogen and carbon dioxide using a patented biocatalyst that has the incredible ability to transform hydrogen and climate-harming CO2 into a drop-in replacement for fossil gas. BioCat Methane has low-carbon intensity and is renewable. It’s a practical, clean fuel poised to accelerate the energy transition. In May 2021, the International Energy Agency (IEA) released its roadmap to help the world get to net zero carbon dioxide emissions by 2050. Net Zero by 2050 recommends a baseline target of 10 percent for synthetic methane in the natural gas flow by 2050.


Environmental Heroes


Archaea are ancient, single-celled microorganisms that survive in extreme conditions. Electrochaea’s biocatalyst is a patented archaea that was selectively evolved for exceptional efficiency. In a single biomethanation reactor, trillions of self-replicating, self-maintaining microorganisms transform hydrogen and CO2 into renewable, synthetic methane. These non-hazardous, environmental champions are helping save the planet.


Power to Gas (P2G)


Electrochaea’s proprietary power-to-gas (P2G) process converts renewable energy into hydrogen through electrolysis. This green hydrogen and climate-harming carbon dioxide are then converted by the archaea into grid-quality renewable synthetic methane for storage and distribution. P2G stores renewable, excess energy in the chemical bonds of gases for use on-demand from the gas grid. Storage of synthetic methane in the gas grid has nearly unlimited capacity and uses existing infrastructure.

Electrochaea is a growth-stage company commercializing a disruptive and scalable technology to meet immediate and growing market needs in North America, Europe and beyond:


  • storing renewable energy
  • displacing fossil gas with renewable natural gas, and 
  • reusing carbon dioxide 


Our proprietary process to produce renewable methane at industrial scale, can be used to green the gas grid, continue to green the power grid, and recycle any source of CO2.

Carbon Recycling


Pipeline-grade BioCat Methane is produced in our scalable and robust methanation system for injection into the gas grid or immediate use with a significantly reduced lifecycle greenhouse gas impact. The carbon dioxide used in our process can be recycled from any source, including anaerobic digestors, landfills, dairies, fermentation facilities, or industrial processes.


A Diversified Energy Transition


The future of energy demands a mix of technologies and sustainable solutions. The path towards zero emissions will require creativity and persistence. 

The high efficiency and robust nature of our biocatalyst enables our patented methanation technology to operate at lower capital and operating costs and with greater flexibility than conventional thermochemical methanation processes. The biocatalyst is remarkably compatible with variable duty cycles and common impurities in CO2 sources. P2G energy storage enables practically unlimited storage capacity via existing gas grid infrastructure. At grid scale, BioCat Methane provides fuel for transportation, residential, industrial, and all other traditional uses of natural gas.
