The European Patent Office (EPO) announced Canadian chemist Donald Sadoway has been nominated as a finalist for the European Inventor Award 2022. He was nominated for inventing a liquid metal battery which can bring more renewable energy onto the electricity grid.

Sadoway’s rechargeable battery degrades less, meaning a longer lifespan than conventional energy storage solutions and can be manufactured with locally sourced raw materials.

“By enabling long-term storage of renewable energy, Sadoway’s invention could help to solve a problem that many have battled for years to overcome,” said António Campinos, President, EPO. “His invention could reduce the cost of storing solar and wind power, providing consumers with more affordable and clean energy, with the potential to mitigate climate change in a sustainable manner.”


Sadoway is named as one of the three finalists for the European Inventor Award in the “Non-EPO countries” category, which recognizes inventions developed outside Europe. The winners of the 2022 edition of the EPO’s European Inventor Award will be announced at a virtual ceremony in June.
