The round was led by EIT InnoEnergy and supported by InnovationQuarter, Invest-NL, Init Power, and a group of business angels This is a significant milestone in the company’s roadmap to bring low-cost, sustainable LDES to the European market by 2026. Commenting on the use of the funds, Jiajun Cen, CEO and co-founder, said: “The capital will catalyze the development of our first standardized battery module and boost the hiring of top-tier talent to the team”.    AQUABATTERY is developing a novel flow battery that can store clean electricity in table salt and water for 8 hours or longer. When charged, the battery converts saltwater into acid and base and reverses the process when discharged. The company is preparing to launch its fourth pilot battery in Delft later this autumn.    Roel van Diepen, Investment Director EIT InnoEnergy Benelux, commented on the deal: "It confirms the key role we expect flow batteries to play in our future energy system as we see the technology maturing into commercially viable solutions."  ![Jiajun Cen, co-founder and CEO, and Emil Goosen, co-founder and COO.](https://26867598.fs1.hubspotusercontent-eu1.net/hub/26867598/hubfs/0423%20AcuaBatterry%20DSC_1880m-1.jpg?width=1200&length=1200&name=0423%20AcuaBatterry%20DSC_1880m-1.jpg) Jiajun Cen, co-founder and CEO, and Emil Goosen, co-founder and COO. ![AquaBatterry team](https://26867598.fs1.hubspotusercontent-eu1.net/hub/26867598/hubfs/0423%20AcuaBatterry%20DSC_2177m-1.jpg?width=1200&length=1200&name=0423%20AcuaBatterry%20DSC_2177m-1.jpg) With the European Union aiming to triple its renewable generation capacity by 2030, LDES will be crucial to provide intra-day, multi-day and seasonal flexibility. Invest-NL's Bram Sprangers adds that the energy transition will benefit from solutions such as AQUABATTERY as "long duration energy storage will become a cornerstone for integrating renewables into the grid, resolving network congestion, and accelerating industrial decarbonization.”      In addition to its value to a net-zero energy system, AQUABATTERY’s use of table salt and water, which are abundant and non-toxic materials, creates social and environmental benefits in the Netherlands and elsewhere. Nathal van Rijn, director of InnovationQuarter says: “We are happy to invest in a sustainable storage system that has low environmental impact and a high potential to boost battery capacity in the world in the coming years.”    ![Invest-NL Logo](https://aquabattery.com/hs-fs/hubfs/InvestNL%20_logo.png?width=417&height=121&name=InvestNL%20_logo.png) ![Innovation Quarter Logo](https://aquabattery.com/hs-fs/hubfs/Innovation%20Quarter_logo.png?width=286&height=176&name=Innovation%20Quarter_logo.png) ![EIT InnoEnergy Logo](https://aquabattery.com/hs-fs/hubfs/InnoEnergy_logo.png?width=367&height=137&name=InnoEnergy_logo.png) ![Aquabattery Logo](https://aquabattery.com/hs-fs/hubfs/Logo_AB.png?width=1584&height=389&name=Logo_AB.png)   **About AQUABATTERY** A Dutch climate tech startup, developing a novel long duration energy storage solution based on saltwater.
