Latest Battery Technology Innovations
These presentations were made in a well-attended mini-symposium, The latest in Battery Technology, at TU Delft, May 9, 2019, organised by KIVI section Dutch Process Technologists and Technologisch Gezelschap, student study association of TU Delft:
Battery technology based on the potential difference between water and salt-water
David Vermaas, co-founder of Aquabattery, presented his battery technology based on the potential difference between water and salt-water and applying ion-exchange membranes to store and regenerate electricity. This technology is the reverse of reverse electrodialysis as researched by Joost Veerman and others in WETSUS.
Overview and insight in battery innovations
Erik Kelder, ass. Professor of TUD, provided an overview and insight in battery innovations for small scale and industrial scale applications. For the latter he reported that the investment cost should be less than 75 €/kwh to become economically attractive. For a 1000 MW power station storing its electricity for 12 hours; it means that the investment cost should be less than 1000 M€. This target figure should help designers to assess different battery technologies and identify promising options.
