Patented high-efficiency energy technologies, enabled by two-phase flow turbomachinery

Tifeo develops patented high-efficiency energy technologies — combined cooling, heating and power, high-temperature heat pumps and long-term electric energy storage — and the new generation of two-phase flow turbomachinery that enables their large-scale commercialisation. This turbomachinery will first be deployed in conventional plants across the energy, hydrocarbon, cryogenic and chemical sectors.

Three patented high-efficiency energy technologies

Tifeo's patented high-efficiency energy technologies are based on advanced thermodynamic cycles enabled by two-phase flow expansion and two-phase flow compression processes.

Combined cooling, heating and power (CCHP)

The CCHP plant utilises renewable heat sources (such as biomass, geothermal, solar, and waste heat) or traditional heat sources (such as gas, oil, nuclear microreactors) to supply the end-user with electric, heating and/or cooling power.

High-temperature heat pump (HTHP)

The HTHP plant harnesses thermal power at low temperatures provided by any renewable or traditional heat source to supply the end-user with high-temperature heating power. The same plant layout can operate reversibly in the CCHP mode.

Patent
WO2024033752 — international (PCT) application with a fully favourable EPO opinion; national phase in Europe and the USA

Long-term electric energy storage (LTEES)

The LTEES plant is a thermo-mechanical storage system in which energy is stored in the working fluid itself, without the need for cryogenic or high temperatures, and is returned as electricity and, where required, as heat.

Two-phase flow turbomachinery

The innovation

Two-phase flow turbomachinery developed to date has shown modest efficiency at design point and significant performance degradation in off-design operating conditions. This has led to sporadic deployment due to limited economic viability, confined to narrow power bands. Tifeo's two-phase flow turbomachinery overcomes these limitations thanks to the modular design of its proprietary hydraulic cells — high efficiency across a broad operating range, and scalability from tens of kW to tens of MW — thereby making deployment economically viable and enabling widespread adoption for the first time.

The first applications

Tifeo will deploy its proprietary two-phase flow turbomachinery initially in a broad range of conventional plants across the energy, hydrocarbon, cryogenic and chemical sectors, in order to generate revenues at an early stage. Sales of complete turbomachinery will begin in Year 4 of the four-year development programme.

Energy plants

Industrial refrigeration, HVAC & data-centre chillers, steam / ORC / geothermal power, heat pumps

Hydrocarbon plants

Oil & gas wells, oil refineries

Cryogenic plants

Liquefaction & separation — ASU, LNG, LPG / NH₃

Chemical plants

High-pressure synthesis reactors

Central estimates. Data-centre chillers follow in the expansion stage; geothermal, ORC and cryogenic plants in the follow-on stage.

From Year 3 of the development programme, Tifeo will also license its proprietary hydraulic cells to established turbomachinery OEMs serving the subsea and extreme (high-pressure/high-temperature) oil & gas markets. These licensing revenues, together with those from after-sales services, represent additional upside and are not included in the financial projections. The scale-up of Tifeo's patented high-efficiency energy technologies towards commercialisation will be progressively self-funded through the revenues generated by the turbomachinery business.
