Toyota, NREL to work on 1 MW PEM fuel cell power generation system
Toyota Motor North America and U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) are collaborating to build, install and evaluate an advanced 1 MW proton exchange membrane (PEM) fuel cell power generation system at NREL's Flatirons Campus in Arvada, Colorado.
The fuel cell power system will be installed this summer, and the full system will be commissioned later in 2022.
According to the announcement, this 3-year, $6.5 million collaboration is funded in part by DOE's Hydrogen and Fuel Cell Technologies Office in the Office of Energy Efficiency and Renewable Energy. The project supports DOE's 'H2@Scale' vision for clean hydrogen across multiple applications and economic sectors.
The MW-scale fuel cell system integrates multiple Toyota fuel cell modules into a larger system to provide responsive stationary power. NREL has already demonstrated the use of an automotive fuel cell system to provide carbon-free power for a data center.
This new system is at a significantly larger scale, generating about 15 times more power and capable of direct current and alternating current output, according to Toyota. The company is leveraging its 25 years of fuel cell development experience for the designing of the system, expanding its hold beyond automotive fuel cell market.
Toyota is providing the fuel cell modules, while Telios is working as system integrator for the design and build of the system for delivery to NREL. The company has developed an integrated control system to manage operation of the fuel cell modules to maximize efficiency and system life. The system demonstrates a simplified design as a drop-in replacement to a conventional generator.
"Achieving carbon neutrality requires all of us to explore new applications of zero-emission technology, including how that technology will integrate with other systems, which the project with NREL will identify," said Christopher Yang, group vice president, Business Development, Fuel Cell Solutions, Toyota.
"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", he added.
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 development of future applications. R&D will also include assessing how the system performs when integrated with energy storage and renewable energy generation systems, such as solar photovoltaic and wind.
"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," said Daniel Leighton, an NREL research engineer and principal investigator on the project. "This fuel cell generator system also creates a new megawatt-scale fuel cell research capability at NREL."
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 that includes 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.
