Cheesecake Energy aims to allow 100% penetration of renewable energy to power electricity grids and mini-grids right across the globe. As an OEM supplier of hardware solutions to energy storage project developers, our Supertanker product provides the cheapest and greenest energy storage technology, which can be sized, transported and installed very flexibly and quickly. It works by using electricity to compress air and storing the high grade heat and high pressure air until the electricity is needed again when the air is reheated and expanded to drive a motor which generates converting the stored energy back to electricity. The optimal size of a Supertanker system is ideal for charging fleets of electric vehicles, supplying a residential neighbourhood or factory, or helping renewable generators to manage intermittency. A full size, full system prototype will be completed in 2020.
