enegy storage

The Australian Renewable Energy Agency (ARENA) will broaden its mandate to explore the development of energy storage and hydrogen after securing fresh funding.

Hawaiian Electric has submitted eight contracts representing nearly 300MW of solar energy generation and about 2,000MWh of energy storage to be built on the islands of O'ahu and Maui.

Solar is the key alternative energy source going forward despite overcast skies and land constraints, says Chan Chun Sing.
