Distributed Heat Pumps

Detailed overview of innovation with sample startups and prominent university research

What it is

Distributed heat pumps refer to a network of smaller, individual heat pumps installed in buildings or across a district, rather than relying on a single, centralized heating and cooling system. This decentralized approach offers several advantages, including increased efficiency, flexibility, and resilience.

Impact on climate action

Distributed Heat Pumps under the Heat Pumps theme enhance climate action by providing efficient heating and cooling solutions. By utilizing renewable energy sources like electricity, these systems reduce reliance on fossil fuels, decrease carbon emissions, and promote energy efficiency, accelerating the transition to a low-carbon heating and cooling sector.

Underlying
Technology

Heat Pumps: Individual heat pumps are installed in each building or zone, providing localized heating and cooling. These can be air-source, water-source, or ground-source heat pumps, depending on the available resources and application.
Smart Controls and Communication: Each heat pump is equipped with smart controls and communication capabilities, allowing for individual control and optimization of heating and cooling in each zone.
Energy Management Systems (EMS): An EMS can be used to monitor and control the entire network of distributed heat pumps, optimizing energy usage and ensuring grid stability.
Renewable Energy Integration: Distributed heat pumps can be integrated with renewable energy sources, such as solar PV or geothermal energy, to further reduce reliance on the grid and lower carbon emissions.
Thermal Storage: Thermal storage systems can be incorporated into distributed heat pump networks to store excess heat or cold for later use, improving efficiency and flexibility.
