Concept · For district heating plants
Wind energy directly into the heating network
An off-grid system in which a wind turbine and a heat pump deliver heat directly to the district heating network, without the energy passing through the power grid.

Background
Today, wind energy reaches district heating via the power grid
Wind power for district heating currently runs through the electricity grid, with everything that involves: waiting for a grid connection, paying tariffs and levies that end up in the price of heat, and meeting the grid's technical requirements.
- Step A
Wind turbine
produces electricity, which is sent out on the power grid
- Step B · Bottleneck
Power grid
- Grid connection and waiting time
- Tariffs and levies
- Grid compliance requirements
- Step C
Heating plant
buys the electricity back and converts it into heat
Every detour costs time, money and capacity on the grid.
Principle
Turbine and heat pump: one system, no power grid
The heat pump draws its heat from air, ground, geothermal sources, seawater, waste heat or wastewater, depending on what is available on site. The wind turbine and the heat pump are one integrated system: the turbine drives the heat pump directly. Hot water goes through a heat store to the heating plant and on to homes and industry. The heat pump can also supply industry directly.
Benefits
No grid, no grid requirements, with its own heat storage
- 1
Puts no load on the power grid
The energy goes directly from turbine to heating network. No grid connection and no competition for capacity.
- 2
Energy is stored as hot water
Production and consumption are decoupled. The heat store evens out variations in the wind.
- 3
No grid compliance requirements
The system is designed for off-grid operation. This can simplify the turbine and potentially reduce the capital cost.
- 4
Proven components
Known technology, combined in a new system architecture that has not been seen before.
- 5
No grid tariffs or levies
The energy never passes through the power grid, so grid tariffs and electricity tax on the power fall away.
- 6
Lower energy losses
The turbine drives the heat pump directly, with no conversion to electricity and back. Fewer steps mean fewer losses.
The wind's energy becomes heat in your network without passing through the power grid.
Storage
The heat store evens out the wind
When the wind blows, the heat store is charged. When it is calm, the network is supplied from the store.
Heating plants already know accumulation tanks. What is new is that the wind's energy goes straight into the tank, without first being turned into electricity on the grid. The store bridges the gap between when the wind blows and when the town needs heat.
Technology
Proven components, low technological risk
None of the parts is new technology. What is unique is the coupling, developed by engineers with experience from both wind turbines and heat pumps.
Wind turbine
Well known and reliable
Heat pump
Mature technology in district heating
Heat storage
Accumulation tanks you already know
Off-grid wind heat
A coupling not seen before
The technological risk is not in the components; they are proven. What is new is the way they are coupled.
Next step
Become the first heating plant with off-grid wind heat
We are looking for heating plants that want to join from the start, as pilot and technical sparring partner.
