Green-Y provides a combined solution to tackle two major challenges of our energy future:
1. How to efficiently store electricity from renewables?
2. How to provide heating & cooling from renewables?
We give the answer by combining the electricity storage with a heating and cooling unit in one decentralised device: "Green-Y = Battery + Heat Pump". This leads to a highly efficient tri-generation energy storage system which allows storing electricity far below 1 ct/kWh.
