Idaho National Laboratory Testing of FuelCell Energy’s Electrolyzer to Show Further Commercialization Opportunity for Nuclear Power Plants

Rhea-AI Summary

FuelCell Energy (FCEL) has begun testing its solid oxide electrolysis cell (SOEC) system at Idaho National Laboratory (INL), marking the largest and first fully integrated electrolyzer tested at the facility. The project, partially funded by a 2020 DOE award, aims to study hydrogen production's role in diversifying nuclear plants' profitability.

The system will produce 150 kilograms of hydrogen daily using 250 kilowatts of nuclear-generated electricity, demonstrating 100% efficiency when utilizing nuclear plant waste heat. This efficiency could reduce clean hydrogen production costs by up to 30%. The electrolyzer's modular design, shipped on two flatbed trucks, offers easy scaling and siting capabilities.

The testing will evaluate real-world applications, including thermal energy usage from nuclear reactors, grid dynamics, and reactor control simulation. The system will also be showcased to global energy industry visitors at INL, with produced hydrogen supporting ongoing research in e-chemical synthesis, turbine co-firing, and vehicle refueling.

DANBURY, Conn., Feb. 06, 2025 (GLOBE NEWSWIRE) -- FuelCell Energy (NASDAQ:FCEL) announced that its solid oxide electrolysis cell (SOEC) system has begun a testing and validation period at the U.S. Department of Energy’s Idaho National Laboratory (INL), which focuses on innovations in nuclear research, renewable energy systems and security solutions.

The project, funded partially by a 2020 U.S. Department of Energy Office of Nuclear Energy award, will study how hydrogen production operations can help nuclear plants diversify and increase their profitability by switching between electricity production and hydrogen generation. The testing will also look at the potential of advanced small modular reactor designs (200 to 500 MWs in size) paired with FuelCell Energy’s SOEC utility scale electrolzyers.

The testing involves the largest electrolyzer to be studied at INL, and it is expected to show that the technology can reduce the cost of clean hydrogen production by converting 100% of the electricity and water fed into the system into zero carbon hydrogen. Additionally, the FuelCell Energy electrolyzer

• will produce 150 kilograms of hydrogen per day,
• from 250 kilowatts of nuclear energy-generated electricity,
• simulating the benefits of 100% efficiency when waste heat from the nuclear power plant is used.
  

Unlike past testing INL has conducted on electrolysis “stacks,” the FuelCell Energy electrolyzer being studied is a fully integrated solid oxide electrolyzer system.

FuelCell Energy President and CEO Jason Few commented, “Pairing FuelCell Energy’s electrolyzer with nuclear plants is an excellent example of the ‘all-of-the-above' energy strategy that is necessary to meet the needs of a strained electric infrastructure.”

“Nuclear energy is a baseload power source that when paired with FuelCell Energy’s electrolyzer can ensure that every kilowatt of power is converted into a usable or stored energy resource. FuelCell Energy's electrolysis platform can enable 100% smart energy utilization.”

What makes FuelCell Energy’s electrolyzer different?

An electrolyzer is a system that performs electrolysis, which is the process of using electricity to split water molecules (H₂O) into hydrogen (H₂) and oxygen (O₂). Hydrogen produced from electrolysis can be stored long term and transported, allowing energy from wind, solar, and nuclear to be available on demand.

FuelCell Energy’s electrolyzer takes in cold water and electricity and then converts it into hydrogen. And when an external source of heat is added, such as heat from a nuclear power plant, the FuelCell Energy electrolyzer can reach 100% efficiency. At this level, the cost of hydrogen can be reduced by as much as 30%, alleviating cost as a barrier to wider adopting of hydrogen as an energy source.

The INL testing will study real world use cases that incorporate the application of thermal energy from a nuclear reactor, grid dynamics and a nuclear reactor control simulator.

Few concluded, “Energy innovation that drives down costs, emissions, and leverages all the above energy sources we have today is smart energy and a win-win. We look forward to the progress of this testing, which we believe can positively contribute to the ongoing development of nuclear and fuel cell hydrogen technologies to create more abundant energy.”

Despite its capacity, the FuelCell Energy electrolyzer occupies a small footprint with a modular design and was shipped to INL from FuelCell Energy’s headquarters in Connecticut on two flatbed trucks. The system is easy to site, replicate, and scale to the customer’s needs.

While at INL, the FuelCell Energy system will be exhibited to members of the global energy industry who visit the facility to learn about nuclear energy’s ability to generate clean electricity. They will have the chance to learn about clean hydrogen production by combining it with FuelCell Energy’s electrolysis platform. Additionally, hydrogen produced by this system will be used for ongoing research at INL in the areas of e-chemical synthesis, hydrogen turbine co-firing for power generation, and heavy-duty vehicle refueling.
