Dualistic Neighborhood Energy Community
A Kubota 60 kW natural gas engine (see link) can be configured so that all waste heat is utilized for heating purposes, functioning as a mini power plant or a CHP unit (Combined Heat and Power).
When households install thermal storage radiators see
The radiator can be heated using electricity when available and is capable of storing and releasing the heat to the room. Combined with a large electrically heated domestic hot water tank, the household can absorb large amounts of electricity when it is available and remain heated for more than 24 hours without any power supply.
At the school, a heat pump is installed that can cover 100% of the school's heating demand when renewable energy is being produced.
Households and the school connected to the neighborhood energy community install solar panels on their rooftops, and local wind turbines are added to the overall project. This enables both the school and electrically heated homes to be 100% heat-supplied when renewable energy is available.
When renewable energy is not available, the gas engine at the school is started. The waste heat supplies the school, and the electricity from the engine powers the heat pumps in the homes via the electric grid.

Smaller supply areas such as municipalities or larger cities can be supplied from solar cells, on roofs, local turbines and gas engines or biomass power plants.
Here we take a look at the Danish municipality of Odsherred, and look at what it takes to make a municipality with 8000 households and small factories fossil-free from sun and wind and a smaller part biomass and natural gas
