Modular hydrogen electrolyzers | Carbonaxion Bioenergies

Challenge Synopsis

There is a need for high-efficiency, modular, water electrolyzers with a nominal nameplate capacity of 5 MWe, for the local production of hydrogen in small power-to-gas applicatiosn (e.g. production of hydrogen fuel, synthetic methane, etc.).

High Energy Conversion Efficiency. The primary cost driver of green hydrogen is the cost of the renewable electricity. Although the price of renewable electricity is relatively low in Canada, green hydrogen is still more expansive than blue or grey hydrogen. The only avenue left to reduce OPEX is to boost efficiency as high as possible, the closer to 100% the better.

Modularity. Canada is a large country, with many small communities. Labor is expensive and summer, short. To reduce all-up CAPEX, there is hence a premium for electrolyzer systems with « plug-and-play» modularity, easier to couple with modular wind or solar farms.


As indicated above, Canada is a large country, with many small communities, often isolated especially in the North. Even in the South, outside large metropolis, the energy transition will also be implemented through locally available renewable energy sources, such as wind and solar, distributed by their very nature. To that end, Quebec has recently published a Call for Interest on Regional Energy Ecosystems (REE)[1], part of the government’s commitment to encourage the local production and consumption of green hydrogen or bioenergy, hereby increasing the energy autonomy of the region, creating economic and sustainable prosperity and improving the province’s trade balance.

Response Criteria:

The modular, plug-and-play electrolyzer, including the stack, DC power converter, and all ancillary equipment, shall meet the following minimum requirements:

The Opportunity:

As part of the LCBA Canada project, you may have the opportunity to participate in the «Electromethane Neuville» project being developed by Carbonaxion Bioenergies inc. The project is waiting funding from the Natural Resources Canada (NRCan) Clean Fuel Program. CAVEAT: Carbonaxion is reasonably expecting a positive answer before the end of CY 2022, but no assurance can be provided, as of Sep. 20th, 2022.

The objective of the Electro-Methane Neuville project is to ultimately build a power-to-gas facility with a nameplate capacity of approximately 2,500,000 Nm3/year of synthetic renewable natural has (RNG), with a lifetime extending from 2025 up to 2050. Located in Neuville, Québec, the proposed facility is based on an advanced bio-catalytic methanation technology, with the biogenic CO2 coming from a co-located landfill gas (LFG) processing facility.
