The Idaho National Laboratory (INL) and Pacific Northwest National Laboratory (PNNL) have partnered with Idaho Power to explore integrating hydrogen production with hydropower plants to address revenue challenges and environmental concerns. The collaboration, funded by the Department of Energy, aims to enhance profitability and sustainability for Idaho Power's 17 hydroelectric projects. The project focuses on both run-of-river and impoundment hydropower plants, seeking to maximize benefits by utilizing hydrogen in times of low electricity demand. Challenges such as managing fluctuating water flows and complying with environmental regulations have prompted the investigation of hydrogen integration to optimize operations. By producing hydrogen alongside hydropower, operators can store excess energy for high-demand periods or sell it in more stable markets, enhancing revenue streams. Furthermore, the byproduct oxygen from hydrogen production can be used to improve downstream oxygen levels, addressing environmental concerns. Advanced modeling techniques are being employed to determine the best system configurations and applications for hydrogen use, highlighting the potential for increased grid stability and revenue generation. Overall, the project showcases the innovative potential of combining hydropower with hydrogen production to create a more profitable and environmentally sustainable energy generation system in Idaho.
