HTTES — Hybrid High-Temperature Thermal Energy Storage
- Validated technology platform
- Operational pilots in Italy
- Upgraded for high-temperature industrial waste heat capture
- Suitable for integration with district heating and industrial processes
Waste heat is an overlooked energy source.
Roughly 40–50% of energy in industrial processes is lost as waste heat. It often remains unused while end users face high and volatile delivered-heat prices.
Heat-as-a-Service
Customers do not buy equipment. They buy delivered useful heat as a service. WasteHeatHub™ finances, builds, and operates the full waste-heat capture and thermal storage system, while the customer receives contracted heat volume (MWh) at an agreed price and service level.
Technology
WasteHeatHub™ combines two complementary technologies for industrial thermal energy storage.
TCES — Thermochemical Energy Storage
- Advanced solution for seasonal and long-duration storage
- High energy density with near-zero passive losses (<1% per year)
- Technology Readiness Level: TRL6
- Prototype validated in relevant operational environment
Together they enable time-shifting heat use from hours to multiple months with minimal losses.
Technology Readiness & Validation
| Technology | Status |
|---|---|
| HTTES | Validated technology – pilots in Italy |
| TCES Reactor System | TRL6 – Prototype validated in relevant operational environment |
Pilot projects in Italy
WasteHeatHub™ has conducted HTTES pilot projects in Italy, demonstrating the full energy management chain:
- high-temperature waste heat capture
- long-duration thermal storage
- integration with industrial sources
- district-heating supply potential
These pilots indicate the technical and operational viability of a capture-storage-contracted delivery model.
References & Experience
The WasteHeatHub™ concept is built on more than 26 years of experience in energy systems engineering and innovation, validated by:
- international patent filings and protected know-how in thermal conversion and storage
- award recognition at the Innovation Forum in Slovenia
- development of advanced thermal energy systems
- industrial energy efficiency projects across Europe
Our work unlocks the economic value of waste heat and converts it into a reliable and market-ready energy source.

From waste heat to contracted heat supply
One integrated chain: capture at source, time-shift with storage, and deliver heat under contract.
Capture at source
Recover high-grade waste heat without disrupting production processes.
Store & time-shift
High-temperature storage and TCES extend heat availability from hours to multiple months with very low passive losses.
Deliver as a service
Predictable and reliable heat supply: WasteHeatHub™ takes financing, construction, and operations, while the customer receives heat under contract.
