Is thermal energy storage suitable for new builds, retrofits, or both?

Thermal energy storage is indeed suitable for both new builds and retrofits. This technology involves storing thermal energy for later use, which can be beneficial in improving energy efficiency and reducing reliance on fossil fuels.

Suitability for New Builds

In new builds, thermal energy storage systems can be integrated more easily into the design and construction process. This allows for optimal placement and sizing of the storage system, ensuring it works efficiently with other heating and cooling systems. For example, new build developments can incorporate phase change materials or water tanks to store thermal energy, which can be used for heating during colder periods or cooling during warmer periods.

Suitability for Retrofits

For retrofits, thermal energy storage can be more challenging but is still highly effective. Existing buildings often require upgrades to improve energy efficiency, such as replacing outdated heating systems or adding insulation. Thermal energy storage can complement these upgrades by reducing peak energy demands and improving overall energy efficiency. In the UK, retrofitting is crucial as millions of homes need energy efficiency improvements. Thermal storage can enhance retrofitting by providing a flexible and efficient way to use renewable energy sources.

Practical Considerations

Pros of Thermal Energy Storage:

• Energy Efficiency: Reduces overall energy consumption by storing energy when it is abundant.
• Renewable Integration: Can be used with solar or wind power, helping to balance intermittent energy supplies.
• Cost Savings: Reduces energy bills by optimizing energy use.

Cons of Thermal Energy Storage:

• Initial Cost: Installing thermal energy storage systems can be expensive upfront.
• Space Requirements: May require additional space for storage units.

Common Mistakes:

• Insufficient sizing of the thermal storage system for the building's energy needs.
• Poor integration with existing heating or cooling systems.

Real-World Applications in the UK

In the UK, projects like Heat the Streets by Kensa are developing approaches to decarbonize heating by integrating networked heat pumps with thermal storage. This approach aims to replace traditional gas networks with more sustainable options, which can be applied to both new builds and retrofits. Additionally, initiatives like the UK Green Building Council highlight the importance of home retrofitting to increase energy efficiency, where thermal energy storage can play a pivotal role.

Advice for UK Homeowners and Businesses

When considering thermal energy storage for your new build or retrofit project:

• Consult Professionals: Ensure that the system is designed correctly for your specific energy needs.
• Explore Incentives: Look into any available government incentives or grants that could help offset the initial costs.
• Long-Term Benefits: Consider the long-term energy savings and potential increase in property value.
