The global challenge
storing abundant summer energy
for winter demands.
GE4ZERO solution:
Heating and cooling account almost 40% of Europe’s energy related emissions.
Our GE4ZERO System approach
Our system captures surplus summer energy into Underground Thermal Energy Storage and reuses it in winter, creating a closed, zero-emission loop.
Underground Thermal Storage
Solar and waste heat are stored in an underground thermal energy storage (BTES) through boreholes filled with fluid loops.
Solar-Powered Heat Pumps
Solar PV panels provide electricity to power heat pumps that transfer surplus heat into the underground BTES field.
Smart monitoring & analytics
Smart monitoring with DewesoftX, Grafana and FUXA to achieve optimized and sustainable heating and cooling.

How it works
Summer mode
Solar panels power heat pumps to transfer surplus heat into the underground BTES field + air conditioners waste heat
Winter mode
Stored energy is used for underfloor heating and industrial needs – clean, reliable, and grid-independent.
