Massive energy storage using H2 to support the optimal and efficient integration of a pumped hydroelectric power plant

Year: 2024

Type: article

Abstract: In Gran Canaria, the integration of renewable technologies is being investigated to address intermittency in power generation. The future Chira-Soria pumped-storage hydroelectric power plant (PHES), planned for 2030, will be key in harnessing the island's hydro potential. In addition, hydrogen storage is being explored as a viable solution. This method uses electrolysis of water to produce hydrogen during energy surplus, storing it to generate electricity when there is low renewable production. This approach mitigates intermittency, stabilizes the energy system and reduces dependence on fossil fuels. The combination of the Chira-Soria PHES with hydrogen storage will ensure a sustainable and reliable energy supply, contributing to the transition to a cleaner and more resilient energy matrix. The studies seek to optimize this technology, maximizing its efficiency to promote the sustainable development of Gran Canaria and reduce greenhouse gas (GHG) emissions. • H 2 storage reduces emissions by 12.36% vs. PHES; 36.02% vs. no integration. • PHES plant with H 2 storage maximizes surplus renewable energy and system reliability. • H 2 storage optimizes emissions reduction and resource use in an island power system.
