Professor Donald Sadoway from the Massachusetts Institute of Technology has been named a recipient of the European inventor award 2022, under the Non-European patent office categories, for creating a liquid-metal battery that could enable the long-term storage of renewable energy. Donald Sadoways invention may lower the storage costs for solar and wind power, providing consumers with cheaper, cleaner power, potentially mitigating climate change sustainably, said EPO president Antonio Campinos, who announced the finalists of the European Inventor Prize 2022. According to Antonio Campinos, the president of non-European patent offices, the creation is a major step toward the realization of a zero-carbon energy production, as it makes possible to store renewable power at a large scale.

The European Patent Office (EPO) announced that Donald Sadoway, Professor of Material Chemistry at the Massachusetts Institute of Technology, has been nominated for a European Invention Prize 2022, for inventing a liquid-metal battery that could feed more renewable power into the electrical grid. Donald Sadoway was named one of the three finalists for the European Inventor Award 2022 under the Non-EPO countries category, which recognizes inventions developed outside European Member States.

He explained that fundamental research gives customers a chance to tailor every liquid metal battery to local materials that are available. Sadoway and his team are also working on expanding the footprint of liquid metal batteries with the help of fundamental research. 

Sadoways liquid metal batteries provide an important competitive edge over traditional batteries. Canadian chemist Donald Sadoways battery has less degradation, meaning it has longer life than traditional power storage solutions, and it can be made from local-sourced raw materials. Unlike existing batteries, the liquid battery technology is made with metals that are reusable from local sources, can be refilled over the course of years and does not lose their capacity. This technology can lower energy storage costs for solar and wind energy, a critical factor in cutting greenhouse gas emissions.

Canadian-American academic Donald Sadoway of MIT has developed batteries made from liquid metals, which can be used for large-scale storage of renewable energy, increasing the reliability of solar and wind energy, and making it possible to have solar and wind power largely power the electric grid. Professor Donald Sadoway realized that he could combine his earlier expertise in molten salts and liquid metals with his research into batteries to develop a stronger battery that can store power at the scale needed for an electric grid. Donald Sadoway studied chemical metallurgy, specializing in what he called extreme electrochemistry-chemical reactions using molten salts and liquid metals heated above 500degC. After earning a Ph.D., he joined the faculty of MIT in 1978, and began researching new chemical processes for mining metals and patenting a novel approach for making steel, patented as a fabrication technique. Aided by a government grant, in 2009, Sadoway began working with a group of junior researchers to develop the first battery with rechargeable batteries, which stored electrical energy in layers of liquid metal separated by molten salts.
