Manitoba Hydro Using Repurposed Batteries To Store Renewable Energy

0

Electrovaya Inc. says it has signed a contract to develop, construct and demonstrate a utility-scale stationary battery system using end-of-life electric-vehicle (EV) battery packs. According to the company, the repurposed batteries could be used to store electricity generated by wind farms and solar power systems.

The stationary battery system will be implemented at the Manitoba HVDC Research Centre facility, a subsidiary of Manitoba Hydro, and will also involve participation from the University of Manitoba, Electrovaya says.

Major funding for the project comes from the Government of Canada's Clean Energy Fund and Manitoba Hydro, and the program is a part of a $7.6 million, Electrovaya-led project.

Dr. Sankar Das Gupta, CEO of Electrovaya, says the project will help show the potential for the reuse of lithium-ion batteries for EV and grid applications.

‘This project will give us insight into the complete reuse of lithium-ion batteries,’ he says. ‘Our hope is that utilities will be able to take advantage of the significant number of the used batteries that will come into the market after the large-scale introduction of plug-in electric vehicles.

‘By making the end product reusable by utility companies, we address two problems,’ Das Gupta continues. ‘First, lithium-ion batteries become an even more environmentally sustainable product, and two, we help utility companies make wind and solar energy generation as reliable as hydro, nuclear and coal.’
