The H2@Scale project is demonstrating several “use cases” for co-located hydrogen production and application. Feedstocks of low-carbon electricity (shown in orange) and renewable natural gas (shown in purple), along with deionized water (shown in blue), are converted to hydrogen (shown in green) by electrolysis and steam reformation, respectively. Clean hydrogen is then used to generate electricity in fuel cells for the Texas Advanced Computing Center.
Use cases being demonstrated by the project include:
- Solar load-following electrolytic hydrogen production for later use in stationary power and electric vehicle fuel cells
- Wind load-following electrolytic hydrogen production for later use in stationary power and electric vehicle fuel cells
- Overall increased utilization of variable renewable energy (decarbonization and energy storage)
- Hydrogen production from renewable natural gas to decarbonize the life-cycle emissions for hydrogen fuel cell power generation
- Increased capacity factors for equipment producing hydrogen for fuel cell electric vehicles by adding a co-located stationary fuel cell (powering a data center)
