We connect with and invest in companies that are complementary in the energy transition. If you think we can add to your concept, feel free to contact us. “We reinforce our common features with our partners and add specific expertise and skills. And at the same time we are champions at both rationalising challenges and realising them”.
Newly built houses with battery-driven quick charger supplied by EF-Charge & Storage. The charger also serves as a neighbourhood battery to buffer generated solar power.

The houses exchange energy with each other with the help of monitoring and smart software.
The neighbourhood battery serves as a buffer and also as a fast charger.
