A revolutionary design

At the heart of EHG's success is their uniquely redesigned and proprietary fuel cell microstructure. Unlike conventional fuel cells, EHG's technology delivers the same power output—up to 40 kW—with a 50% volume reduction. This remarkable achievement has garnered significant interest from specific customers and industry players. As Chris Brandon and Mardit Matian explain, the secret lies in the optimized application of basic physics within the fuel cell. This has resulted in a highly efficient and compact design.

This innovation is not just about size and efficiency. By eliminating expensive components typically required in the balance of plant (BOP), EHG has significantly reduced the overall cost of their fuel cell systems. This cost-effective approach can change the perception that fuel cells are prohibitively expensive, making them a viable option for many applications.

Endorsement and qualification

A significant milestone was the recent certification of EHG's fuel cells by DNV (NL) for marine applications. This certification underscores the robustness and reliability of their technology in demanding environments, paving the way for broader adoption in the maritime industry.

This collaboration was made possible through the CalTestBed program, supported by New Energy Nexus, an international non-profit that funds and accelerates clean energy entrepreneurs. Such partnerships have validated EHG's technology and showcased its potential to transform various industries.

Technological Edge

EHG's fuel cell stacks feature advanced features:

· High Power Density: Their patented microstructure offers power outputs ranging from 5.0 kW to 320 kW.

· Simplified System Architecture: EHG's design minimizes parasitic loads, enhancing system efficiency.

· Flexibility: Their stack design can scale to over 300 kW, accommodating various application needs.

· Cost Reduction: By focusing on design for manufacturing, EHG has achieved radical cost reductions, making its technology more accessible.

The company's proprietary production machinery, developed with a specialized Swiss industrial partner, further enhances its competitive edge. This machinery offers reduced manufacturing costs, higher production rates, and integrated quality control features, ensuring high yield and efficiency.

EH Group’s newly launched 250kW fuel cell system is based on its single 300kW stack and single balance of plant. The result is a more compact and cost effective fuel cell system, that can be stacked to deliver 3+MW of power in a standard 40-foot container. It opens up a raft of new market opportunities from data centres to marine vessels.
