Challenge 1: How to efficiently store electricity from renewables?
Challenge 2: How to provide heating & cooling from renewables?
Green-Y = Battery + Heat Pump
We give the answer by combining the electricity storage together with a heating and cooling unit in one decentralized device. This leads to a highly efficient tri-generation energy storage system which allows electricity storage far below 1 ct/kWhel.
The integration of renewable electricity on a large scale is only possible with a competitive electricity storage. The combination of heat, cold and electricity in a single device is game changing. The cost per stored electricity becomes unrivaled low at high energy efficiencies. Worldwide, every building is in need of heat, cold and electricity. Since heat and cold can be stored easily and at low cost, the generation of it can be shifted in time according to the availability of solar and wind energy.
Efficiently integrate the continously increasing share of renewable energy sources in order to provide sustainable green electricity at a low price while protecting the environment
Highly fluctuating energy sources and low flexibility in energy consumption lead to excess off peak energy and energy shortages during peak hours
We aim to build a highly economical, clean & efficient energy storage system by combining production and storage of heat, cold and electricity
We combine electricity, heat and cold in one decentralized device and provide it WHEN and WHERE it is needed
