Main benefits of TES

• Energy Efficiency and Cost Savings: TES enables peak-shifting, reducing energy consumption during high-demand periods. This leads to lower energy costs for industries, buildings, and communities.
• Flexibility in Energy Systems: By providing demand-side flexibility, TES facilitates grid stability, congestion management, and participation in reserve markets. This flexibility is essential for integrating renewable energy sources and supporting electrification.
• Decarbonisation and Emission Reductions: TES solutions play a vital role in reducing CO₂ emissions by enabling cleaner heating and cooling alternatives and supporting the use of renewable energy sources across industrial and residential sectors.
• Sustainability and Circular Economy: TES systems promote sustainable energy use without reliance on critical raw materials (CRMs) and minimize harmful waste. Lifecycle assessments and circularity considerations are integral to technology development.
• Sector Coupling and Hybrid Solutions: TES facilitates the integration of multiple energy systems (e.g., coupling with heat pumps and batteries), improving overall system efficiency and resilience.
• Industrial Innovation and Value Creation: By collaborating with industry partners, GS TES accelerates the development and deployment of TES solutions tailored to real-world applications, enhancing competitiveness and driving economic growth.
• Workforce Development: Through research projects, student involvement, and training programs, GS TES contributes to educating future experts, ensuring long-term knowledge transfer and capacity building.

These benefits underpin GS TES’s mission to position TES as a cornerstone technology for achieving a greener, more energy-efficient, and sustainable future.
