Toyota & NREL to advance MW fuel cell systems

This fuel cell generator system also creates a new megawatt-scale fuel cell research capability at NREL.

Toyota Motor North America is collaborating with the US Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) to build, install and evaluate a 1-megawatt (MW) proton exchange membrane (PEM) fuel cell power generation system at NREL’s Flatirons Campus in Arvada, Colorado.

This 3-year, $6.5 million collaboration is partly funded by DOE’s Hydrogen and Fuel Cell Technologies Office in the Office of Energy Efficiency and Renewable Energy and supports DOE’s H2@Scale vision for clean hydrogen across multiple applications and economic sectors.

The 1-MW fuel cell system integrates multiple Toyota fuel cell modules into a larger system to provide responsive stationary power. Through a previous collaboration, NREL has demonstrated the use of an automotive fuel cell system to provide carbon-free power for a data centre. This new system is at a significantly larger scale, generating about 15 times more power and capable of direct current and alternating current output.

Toyota is providing the fuel cell modules and is working with systems integrator, Telios, for the design, balance-of-plant and build of the system for delivery to NREL.

NREL researchers will push the operational boundaries of the fuel cell system design to identify performance limitations and degradation over time, generating valuable real-world data to aid with the development of future applications. Research and development will also assess how the system performs when integrated with energy storage and renewable energy generation systems, such as solar photovoltaic and wind.

The fuel cell generator is part of the Advanced Research on Integrated Energy Systems (ARIES) megawatt-scale hydrogen system being designed and commissioned at NREL’s Flatirons Campus. The flexible system —a 1.25-MW PEM electrolyzer, 600-kg hydrogen storage system and 1-MW fuel cell generator — provides a platform to demonstrate direct renewable hydrogen production, energy storage, power production and grid integration at the megawatt scale.

The fuel cell generator system will be installed this summer, and the full system will be commissioned later in 2022.

Christopher Yang, Group VP at Toyota, said, “The application of our modules in deployments of this magnitude shows the scalability of Toyota’s fuel cell technology, whether it is a single fuel cell module for one passenger vehicle or multiple systems combined to power heavy-duty equipment.”

Daniel Leighton, an NREL research engineer and principal investigator on the project, said, “We will study the scaling of PEM fuel cell systems for stationary power generation to understand what the performance, durability and system integration challenges are.”
