Thermal Booster
A Heat-Driven Heat Pump for Boosting Low-Grade Heat
Greenco Tech’s Thermal Booster is a unique heat-driven heat pump that transforms low-grade heat into higher-value thermal energy. By coupling a heat engine with a heat pump in a smart and efficient thermodynamic cycle, the Thermal Booster delivers significantly more usable heat than the input, all without electricity.
It works by combining input heat with absorbed renewable or waste heat, boosting the output beyond what conventional systems can provide. That’s why we call it the Thermal Booster.
How It Works
The principle is simple yet powerful:
- The Heat Engine converts high-temperature heat (e.g. 600 °C) into useful work (W₁), while rejecting part of the input as lower-grade heat (Qw₁) at a useful temperature.
- This work (W₁) drives a Heat Pump, which absorbs colder energy (e.g. 0 °C) and upgrades it into additional useful heat (Qw₂, e.g. 100 °C).
- The result is two combined heat streams (Qw₁ + Qw₂), both delivered at the desired temperature (e.g. 100 °C).
This boosted heat output is significantly higher than what conventional thermal systems provide.
Why It Matters
- +50% more usable heat from the same input source
- Fully heat-driven; no electricity required
- Climate-safe refrigerants; no greenhouse gases, zero GWP
- Compact & modular; scalable from small to large systems
- Flexible integration; compatible with waste heat, solar thermal, and thermal storage
This breakthrough allows industries and communities to do more with the heat they already have.
Applications
- Agriculture: greenhouse heating, food processing
- Industry: dairy, small factories, process steam
- District heating: local networks seeking higher efficiency
- Future uses: cement & steel, carbon capture, hybrid renewable systems
Where We Are Today
The Thermal Booster is currently at TRL 3–4, validated at lab scale as proof of concept.
Our work is co-funded by Vinnova (Innovativa Startups) and the Swedish Energy Agency (Energimyndigheten), providing early validation and support for the technology’s development.
We are now advancing toward the pilot stage, with a focus on:
- Building and testing prototypes to validate performance in real conditions
- Securing pilot partners in agriculture, industry, and district heating
- Preparing for follow-up funding and scale-up to enable wider deployment
- Exploring opportunities to apply the technology where it creates the greatest value
This is the ideal moment for partners to engage with us and help shape the first demonstration projects.
