Between 2021 and 2024, together with other 16 partners from different European countries, Optima joined the European project LOLABAT that was awarded a Horizon 2020 program grant of more than 7 Mio€ by the European Commission to develop a new promising Ni-Zn battery chemistry for stationary energy storage, that uses abundant and available raw materials, non-toxic elements, and presents the energy and power densities both highest after Li-ion batteries with high safety, low risk of thermal runaway, limited environmental impact and high recycling potential. We were as task leaders involved in two critical tasks: A Traditional Environmental Life Cycle Analysis (LCA) and Business Models for Rechargeable Nickel-Zinc Batteries (RNZB). Specifically, regarding the LCA task, a joint journal article titled “A Formulation Model to Compute the Life Cycle Environmental Impact of NiZn Batteries from Cradle to Grave” was published by OPTIMA together with another task partner (https://doi.org/10.3390/en17112751).
