Calmac puts energy storage on ice

Calmac’s IceBank system is now storing excess energy generated by the Dundalk Institute of Technology (DkIT)’s wind turbine, the company has announced. The system effectively stores energy from the world’s first-ever large commercial on-campus wind turbine in the form of ice, which is then used the next day to cool students and faculty in the institution’s PJ Carroll building.

In 2012, before being equipped with energy storage, the wind turbine produced 1,440 MWh, 79% of which was consumed by the university. The remainder was sold back to the grid.

Calmac and its UK distributor LTi Applied Systems Technology have now provided the technology to allow DkIT to smooth its electricity grid demand profile by shifting a portion of the PJ Carroll building’s demand from on-peak to off-peak times, thus allowing even more renewable wind energy to be used on site.
