Electrolyzer solutions in today’s market all appear identical: monolithic, large-scale, centralized.

HEVO 2023

We have taken a radically different approach in the development of our patented Proton Exchange Membrane (PEM) electrolyzer technology: the HEVO. The HEVO is a miniaturized electrolyzer that sits at the core of each of our products and unlocks cost-competitive green hydrogen solutions at any scale and for any application. By contrast, we have arrived at a solution that is unlike any other in the market today, the HEVO.

We designed the HEVO from the inside-out, building on a completely new approach to membrane electrode assembly (MEA) and electrochemical cell design which allows for unprecedented modularity, cost reduction and process simplification. Each of our MEAs is the size of a business card, compared to the membranes used in a traditional PEM electrolyzer which are the size of a sheet of printer paper, which enables near immediate response times to rapid fluctuations in power supply.

The revolutionary HEVO is at the heart of our entire product suite. The HEVO can be grouped in different ways to best suit the client needs, the conditions of where it will be installed and the total size of the system. Fusion Fuel has created the following offerings that can suit most client needs, these are the HEVO-Chain, with its Series NC and Series C version, as well as the HEVO-Solar.

Advantages of our
HEVO Mini-PEM Architecture

Cheaper
power equipment

The HEVO’s novel MEA design allows us to use membranes that are smaller and thinner than those used by conventional PEM systems. As a result, our technology has considerably lower amperage requirements than a traditional PEM electrolyzer for the same amount of power, enabling us to use lower-cost power equipment (e.g., low-current rectifiers) in our balance of plant systems.

Improved
long-term performance

In a conventional PEM electrolyzer, each electrochemical cell operates interdependently within the stack, and mismatch interference of individual cells can restrict the performance of the entire system. A unique feature of our HEVO electrolyzer is our proprietary “stack-less” design of sixteen independently operating electrochemical cells, which can decreases mismatch losses by 5-10%.

Lower O&M cost,
increased uptime

Our modular architecture of interconnected HEVO micro-electrolyzers eliminates single points of failure and enables unparalleled reliability and availability. In the event service is required, individual strings of HEVOs can be replaced in-situ and without requiring a full system shutdown, reducing O&M cost and facility downtime.

Superior
response time

The calling card of our HEVO technology is our proprietary miniaturized electrochemical cells, which is what allowed us to rethink the form-factor of the electrolyzer. Each of our MEAs is the size of a business card, compared to the membranes used in a traditional PEM electrolyzer which are the size of a sheet of printer paper, which enables near immediate response times to rapid fluctuations in power supply.

Lower cost
of production

The innovative, simplified design of our electrolyzer unlocks the use of inexpensive structural components, such as injection-molded plastic, and high-throughput production techniques, such as titanium stamping and laser soldering, driving faster and lower cost production.

Designed for
modular deployment

Where others are pursuing economies of scale through larger electrolyzer stacks, we achieve scale advantages through mass, industrialized production of our micro-electrolyzer technology. The lower cost of industrialized production, coupled with the intrinsic advantages of our HEVO architecture, enables unprecedented flexibility and scalability in deployment. Using our building-block approach, we can deliver modular green hydrogen solutions at any scale.
