European Investment Bank Executes a Project Development Assistance Agreement with Malta Iberia to Pursue Spanish 100MW Sun2Store Storage Facility

ALMERÍA, Spain--()--Malta Iberia Pumped Heat Electricity Storage S.L.U. (Malta Iberia), a European affiliate of Malta Inc., has been granted a Project Development Assistance Agreement from the European Union and the European Investment Bank to pursue a 100MW energy storage facility in Spain. Malta Iberia was selected among hundreds of applicants by the European Innovation Fund for its Sun2Store project.

The Sun2Store project in Spain will provide 100MW of thermal energy storage at a ten-hour duration, providing 1,000MWh of clean energy. The storage solution would be the first of its kind in Europe, combining pumped heat technology with molten salt to provide efficient, reliable and dispatchable renewable energy. Malta is partnering with industry-leading manufacturer Alfa Laval on the heat exchangers and Siemens Energy on the project’s turbomachinery.

The Project Development Assistance Agreement will provide Malta Iberia with tailor-made technical assistance by the European Investment Bank and will include an independent technology assessment to verify key technical parameters of the storage facility. Malta was selected as a viable breakthrough technology that is easily scaled and capable of providing timely, high-impact reductions in greenhouse gas emissions.

“We are thrilled that the Innovation Fund has selected Malta’s Sun2Store proposal as a high-quality project that has the potential to aid significantly in our global fight against climate change,” said Malta Iberia Managing Director Michael Geyer. “While Malta has created an innovative, breakthrough solution, the award of project development assistance also demonstrates that our product is viable from a financial and technological perspective.”

Out of over 300 applications, only 15 projects were selected by the Innovation Fund for Project Development Assistance granted by the European Union and executed by the European Investment Bank.

Malta’s progress in Europe comes as the company continues to make progress toward commercialization globally. Malta recently announced a global partnership with Bechtel, a world-leading engineering, construction, and project management company, to identify and seize opportunities to deploy long-duration energy storage plants. In October, Malta and NB Power announced plans to pursue the first long-duration energy storage facility in New Brunswick, Canada.
