Dáil Éireann Debate, Monday - 11 September 2023
160. Deputy Darren O'Rourke asked the Minister for the Environment, Climate and Communications if there are any plans to develop underwater pumped hydro energy storage; and if he will make a statement on the matter. [38706/23]
View answerElectricity storage plays a critical role in providing flexibility to the electricity system by facilitating the integration of renewable generation, supporting the grid, and shifting electricity to the time when it is most needed. We have already seen tremendous progress in terms of the deployment of electricity storage in Ireland, with more than 600MW of batteries currently active on the system and 292 MW of pumped hydro storage (Turlough Hill).
To further support energy storage development my Department is currently in the process of developing a national Electricity Storage Policy Framework that aligns with our renewable energy ambitions, security of supply, and flexibility policy drivers. The Commission for Regulation of Utilities is also reviewing the regulatory treatment of storage, including licensing, charging and market incentives.
While my Department does not develop or support individual energy storage projects, such as novel underwater pumped storage systems, the potential need for the introduction of R&D opportunities and/or a specific procurement framework for long-duration storage is something that is being considered as part of the forthcoming storage policy framework.
Additionally, Enterprise Ireland, the state agency responsible for the development and growth of Irish enterprises, provides various funding opportunities for new ventures, including those that support the energy transition.
