Heat-driven temperature upgrading at TRL 3
A lab-scale concept being developed as a future enabling module within Greenco’s broader thermal-systems architecture.
Greenco has built a laboratory-scale prototype to investigate the thermodynamic principle, component interaction and practical integration of heat-driven temperature upgrading. Further modelling, prototype refinement, testing and validation are required before progression toward relevant-environment demonstration.
Technology philosophy
Greenco is building the core elements of thermal-driven systems
Our R&D portfolio is organised around a small number of technical functions that repeatedly appear in advanced thermal systems. Thermal Booster addresses one of those functions: temperature upgrading.
Preserve thermal or renewable energy across time using thermal storage architectures and suitable materials.
Move heat efficiently between sources, storage, processes and end-use systems through heat exchangers and thermal interfaces.
Increase the usefulness of lower-temperature heat when a process or thermal network requires a higher delivery temperature.
Combine storage, heat recovery, heat pumps, controls and thermal delivery into coherent system architectures.
Research concept
Exploring heat-driven temperature upgrading
The current lab-scale work investigates thermodynamic configurations in which higher-temperature heat provides the driving potential for a heat-pump process that lifts additional lower-temperature heat to a more useful delivery level. A representative future system could, for example, combine high-temperature thermal storage with low-grade recovered heat and deliver upgraded heat to a building or thermal network.
High- or medium-temperature heat provides the thermodynamic input to the upgrading process.
A coupled heat-engine / heat-pump or related heat-driven cycle is studied as the mechanism for lifting additional lower-grade heat.
The aim is to deliver more useful thermal energy at a temperature matched to the downstream application.
R&D questions
What must be validated before the technology can progress
Cycle architecture & operating window
Which thermodynamic configurations are practical across relevant source, sink and delivery temperatures, and where the concept creates real value.
Efficiency & temperature lift
How much useful heat can be upgraded under different boundary conditions, and how sensitive performance is to temperature levels and component losses.
Heat exchangers & working components
What heat-transfer hardware, machinery and working-fluid choices are technically realistic for compact and durable systems.
Connection to storage & recovered heat
How the upgrading stage could interact with thermal storage, waste-heat sources, heat pumps, district energy and future hybrid thermal systems.
Position in the pipeline
A future enabling module, not a separate commercial distraction
Greenco’s near-term commercial focus remains on technologies and ventures that are already closer to validation and market application. Thermal Booster is being advanced in a controlled R&D sequence: the current TRL 3 prototype establishes technical learning, while deeper investment will follow only when the evidence supports the next development stage.
Use the current laboratory-scale system to investigate the core thermodynamic principle, component interaction, instrumentation and practical operating window.
Improve the cycle and hardware, quantify performance under controlled conditions, and establish repeatable evidence for temperature lift, efficiency and stability.
If the evidence supports progression, integrate the technology with thermal storage and recovered-heat sources in a relevant environment before any commercial product pathway is considered.
Potential system role
Where temperature upgrading may create future value
If the concept is technically validated, the strongest role is likely to be in systems where heat is available but its temperature does not match the required use. Examples include recovered industrial heat, thermal storage discharge, district-energy systems and other heat-driven configurations.
Recovered heat upgrading
Increase the usefulness of lower-temperature process or waste heat before reuse elsewhere in an industrial thermal system.
Storage discharge enhancement
Explore how an upgrading stage could extend the useful temperature range or application value of stored thermal energy.
Network temperature matching
Investigate heat-driven upgrading where recovered or distributed heat needs to be lifted to a useful network or customer temperature.
Future thermal-system integration
Combine temperature upgrading with storage, heat recovery, heat exchangers and controls where the total system case is stronger than any component alone.
R&D collaboration
Thermal Booster is a TRL 3 Greenco R&D pathway
We welcome technically relevant research and engineering dialogue, particularly around heat-driven cycles, thermal machinery, heat exchangers, controls and validation methods. The current priority is technical development and evidence, not commercial product sales.
