The project won first place in an online public vote and received the award from Teresa Ribera, Executive Vice-President of the European Commission for Clean, Just and Competitive Transition, at the European Sustainable Energy Week (EUSEW) awards ceremony on June 10 in Brussels. With support from the European Innovation Council and five partners from the energy, housing and utility sectors, AQUABATTERY launched a pilot in Delft in November. There, Europe's largest and most advanced saltwater flow battery was tested, with the aim of gathering crucial insights that will accelerate product development and enable market introduction in 2026. ![Jiajun Cen, Founder and CEO at Aquabattery, holds an award and a framed certificate on stage at the European Sustainable Energy Awards 2025, joined by two women.](https://aquabattery.com/hs-fs/hubfs/Day1.1_123-1.jpg?width=777&height=518&name=Day1.1_123-1.jpg) “By using table salt and water - abundant and environmentally friendly materials - we can reduce Europe's dependence on critical raw materials, avoid the severe environmental degradation caused by open-pit mining of lithium and rare earths, and eliminate the fire, toxicity and explosion risks to humans and habitat near battery sites,” explained Jiajun Cen, co-founder and CEO of AQUABATTERY.
