Hydropower plants often face challenges during periods of low energy demand, affecting their profitability. To combat this issue, the Idaho National Laboratory (INL) and Pacific Northwest National Laboratory (PNNL) have partnered with Idaho Power to explore the integration of hydrogen production with hydropower plants. This collaboration, funded by the Department of Energy, aims to assess the economic and environmental impacts of combining hydrogen production with 17 hydroelectric projects operated by Idaho Power. The project addresses the fluctuations in power output faced by run-of-river and impoundment hydropower plants due to varying water flows and electricity demands throughout the year. Despite the challenges posed by low demand periods, the integration of hydrogen production offers a promising solution. By using advanced modeling techniques, researchers are determining the most beneficial integration strategies to enhance revenue and operational efficiency. Hydrogen, with its multiple applications including transportation fuels and industrial processes, provides a versatile option for hydropower plants. The ability to store clean hydrogen for peak demand periods or sell it in various markets offers a reliable revenue stream. Additionally, the byproduct of oxygen from hydrogen production can be utilized to improve water quality downstream, further enhancing the environmental impact of hydropower operations. Through this innovative approach, hydropower operators in Idaho could not only improve their revenue streams during challenging times but also contribute to grid stability and environmental conservation.
