About PureCell®

Our current core product offering is PureCell®, a phosphoric acid fuel cell (or PAFC) unit for stationary applications. Stationary application means fixed at a particular site, compared to mobility and transport applications.

Our PureCell® product is a modular unit that can be configured to generate electricity up to 460 or 440 kilowatts (which can power approximately 340 average US households), plus both low- and high-grade heat. PureCell® can be run with different types of fuels, namely, hydrogen, natural gas or liquefied petroleum gas (LPG). Each of our with each unit capable of powering over 340 average U.S. households. Our PureCell® product operates relatively quietly (quieter than piano playing sounds), and has a small footprint for flexible (and even stacked) installation. Mostly importantly, because it relies on an electrochemical process involving hydrogen and oxygen, rather than combustion using fossil fuels, our PureCell® unit creates substantially lower greenhouse gas emissions than conventional power plants when fueled by natural gas or LPG, and zero emissions when fueled by hydrogen.

In addition, our PureCell® units are designed with a target system life of 20 years and a target cell stack life of 10 years, which are among the longest in the commercially available fuel cell market today. Our PureCell® product has a particular advantage in efficiency, durability and pricing for applications that benefit from co-generation of power and heat.

We are the dominant manufacturer of PAFC product with the capability to monitor and service our products on a real-time basis, and our customers rely on us for effective and timely technical maintenance and support services.

Our Upcoming Hydrogen Solutions

HyAxiom seeks to be at the forefront of the hydrogen revolution and deliver a full spectrum of reliable, cost-effective hydrogen solutions for a carbon-free future. Our current product line-up ranges from electrolyzers for scalable green hydrogen production and fuel cells for mobility applications, including long-haul maritime transport and to bus, trucks and other heavy-duty commercial land-transport vehicles.

Proton Exchange Membrane (PEM) Electrolysers

PEM electrolyzers generate hydrogen by breaking up water molecules through an electrochemical process called electrolysis. When powered by renewable sources of energy, such as solar or wind, electrolyzers can produce clean hydrogen for various on-site applications such as blending with natural gas to serve as feedstock for combined cycle power plants or as a means of storage for electricity, thus acting as a viable alternative to conventional batters but with a lower environmental footprint, such as those arising from dead batteries. Our PEM electrolyzers are also expected to have a load-following capability—the ability to adjust hydrogen output as electricity fluctuates throughout a day—making it suitable for utilizing electricity generated by wind and solar. Since many governments provide significant subsidies to clean hydrogen users, we expect our PEM electrolyzers to experience substantial growth in demand from countries with substantial wind and solar assets, such as Europe, Australia and the United States.

To capture the large commercial opportunity for on-site clean hydrogen production, we are developing a 1-megawatt PEMEC that is scalable. We are designing our electrolyzer system (both for the 1-megawatt and other multi-megawatt configurations) to offer unique advantages for deployment across a broad range of hydrogen applications, such as hydrogen fueling station for vehicles, hydrogen supply to combined cycle power plants. Currently, we are taking part in two South Korean government-funded R&D initiatives and we are developing PEM electrolyzers with both demand-following capability and load-following capability. Please contact us for more information.

Solid Oxide Fuel Cell (SOFC)

Solid oxide fuel cells can achieve even higher efficiencies due to faster kinetics at higher operating temperatures. Leveraging the know-how from our PAFC technology, we are developing a 300-kilowatt SOFC product in collaboration with a strategic partner. Our SOFC product is being designed to have higher electrical efficiency compared to our current PAFC products, and greater reliability and cost efficiency compared to other SOFC products currently in the market. Additionally, by using nearly identical reversible solid oxide stack design for our solid oxide fuel cell and electrolyzer, we are seeking to drive efficiencies and manufacture at scale. Our SOFC product will augment our product portfolio for the stationary fuel cell market, particularly for mission-critical applications that require round-the-clock uninterrupted supply of electricity such as data centers and ocean vessels.

Solid Oxide (SO) Electrolysers (SOEC)

Solid oxide electrolyzers have higher efficiency for volume production of hydrogen than other electrolyzers. However, to ensure high efficiency, SO electrolyzers require high levels of heat. When excess heat is available, SO electrolyzers produce approximately three to four times more hydrogen at the same power level as PEM electrolyzers. SO electrolyzers also have a higher maximum operating current limit, which allows for better utilization of higher amounts of curtailed energy. For this reason, SO electrolyzers can be particularly viable in sites that produce high-grade heat and cheap electricity, such as nuclear power plants. However, since SO electrolyzers operate in a high heat environment (560 to 800 Celsius), load-following is difficult and therefore not particularly useful for connectivity with solar and wind energy sources. As SOEC technology matures in terms of durability and achieves lower product cost, we expect this technology to capture a growing portion of the clean hydrogen generation market.

Leveraging our expertise and experience from developing our SOFC product, we plan to initially develop a 1-megawatt solid oxide electrolyzer system prototype, with plans to add this prototype to a multi-megawatt system for clean hydrogen production. We will target industrial, utility and independent power producer customers who need to produce clean hydrogen at scale more efficiently than other electrolysis technologies.

Additionally, we plan to explore integrating our solid oxide electrolyzer systems with the heat generated by a nuclear power plant, with plans to commence the pilot phase in 2027. We will target large-scale, energy-intensive, “hard-to-abate” industrial customers like steel, chemical and cement companies, and intend to produce onsite clean hydrogen more efficiently than lower-temperature PEM or alkaline electrolyzers.

Proton Exchange Membrane (PEM) Fuel Cell Powerpacks

For land transportation applications, we are developing a 100-kilowatt power pack, which is a fuel cell based on polymer electrolyte membrane (PEM) technology. These power packs are designed for large vehicles such as passenger buses, heavy- and medium-duty trucks and other industrial vehicles that use diesel engines, which, according to recent estimates, are responsible for 35% of global greenhouse gas emissions in the transportation sector in 2020.

We are currently developing PEM power packs for use in buses, heavy- and medium-duty trucks and other specialty industrial and commercial vehicles. We intend to design our PEM power packs to be compatible with our Tri-Gen System (which can serve as hydrogen-charging stations) and PEM electrolyzers, with the vision of offering an end-to-end solution for the commercial and industrial transportation sector.

Solid-Oxide Fuel Cell Propulsion System

Building on our SOFC expertise for stationary applications, we are engineering a SOFC propulsion system for maritime use. The SOFC propulsion system is expected to be a viable solution for long-haul maritime vessels that will face new emissions requirements pursuant to the next phases of the Energy Efficiency Design Index (EEDI) issued by International Maritime Organization, a special agency of the United Nations responsible for the safety, security and sustainability of international maritime matters.

While certain improvements to the current LNG engines may provide a short-term solution to satisfy the next phase of requirements beginning in 2025, the industry will need a new technology to meet the demands of the subsequent phase, scheduled to come into effect in 2030. Given that the average life of a long-haul maritime ship is approximately 10 years, major global shipbuilding and maritime transport companies are actively seeking LNG engine alternatives that will secure longer-term efficiency for compliance with upcoming regulations.

Our SOFC propulsion system is being designed to be more efficient, durable and cost-effective than alternatives currently available in the market. In addition, our key focus is on ensuring a greater life expectancy for our propulsion units to align with the useful life of the ship it will power, given that the average life of a long-haul maritime ship is approximately 10 years.

Tri-Gen System

The Tri-Gen System, a modification of the PureCell® M400, co-generates hydrogen, electricity and heat on-site simultaneously, making it optimal for use in electric and hybrid vehicle charging stations. Through a wide deployment of these systems, HyAxiom seeks to provide a comprehensive, end-to-end solution for the commercial vehicle mobility market.

HyAxiom expects to install the Tri-Gen System units for a customer in South Korea in 2023, and we expect this system to be commercially available in the United States also in 2023. Our products are being designed to complement and be compatible with one another. Specifically, the hydrogen fuel cells we are developing for the transportation sector, as described above, will be designed to benefit from our Tri-Gen System’s ability to serve as hydrogen charging stations.
