During the trial period, the load from a Hydrogenics HySTAT™ electrolyzer provided frequency regulation in Ontario by responding to power regulation signals from the IESO on a second-by-second basis.

The IESO and Hydrogenics used an electrolyzer installed at the Hydrogenics facility in Mississauga to demonstrate how the hydrogen equipment follows regulation signals in a real-world scenario. This demonstrated better balancing of electrical supply and demand while alleviating local transmission constraints.

‘Hydrogenics’ ability to provide regulation services demonstrates the success of finding new ways to balance supply and demand on a second-by-second basis,’ says Bruce Campbell, Vice President of Resource Integration for the IESO.

‘We are very pleased to have showcased the smart energy grid capability of utility-scale hydrogen technology, which can and will be used for both grid stabilization and energy storage,’ adds Daryl Wilson, President and CEO of Hydrogenics.

Hydrogenics will now apply this knowledge in the development of MW-scale energy storage applications using hydrogen technology.
