What Enertime does

Enertime is a French industrial cleantech company headquartered in Courbevoie (near La Défense), founded in 2008 by Gilles David — a former AREVA Bioenergy executive — to commercialize thermodynamic machines that recover waste heat from industrial processes. Its core product portfolio comprises three machine families: Organic Rankine Cycle (ORC) modules that valorize medium- and high-temperature waste heat into electricity; very high-temperature industrial heat pumps (PAC HT) that elevate low-temperature heat sources for reuse in industrial processes; and gas expansion turbines (turboexpanders) that convert natural gas pressure-reduction energy into electricity and cooling. The company serves energy-intensive industrial customers (glass, cement, steel, foundries, aluminum, biomass) and municipal/governmental operators (waste-to-energy, district heating, geothermal), with a geographic footprint spanning France, China, Thailand, India, and Ukraine and approximately 50% of revenue from exports.

The business model combines one-time equipment sales with three layers of recurring and service revenue: turnkey EPC contracts, four-tier Operations & Maintenance subscriptions, and a distinctive ESCO third-party financing offering operated via its wholly-owned subsidiary Energie Circulaire that allows customers to deploy systems at zero CAPEX. This financing structure — claimed to be unique among industrial energy-efficiency equipment vendors — is intended to lower customer acquisition friction and convert projects into energy-as-a-service cash flows. Enertime was listed on Euronext Alternext Growth under ticker ALENE in 2017, received BPI France's CSR award in 2018 and was named a 2019 Financial Times European Growth Champion, and conducted an OBSA bond-with-warrants issuance in September 2023 and a €4.9M capital increase in February 2024 to finance growth and Energy Economy Certificate (CEE) prefinancing. In 2024 the operating brand was transitioned to Heatlift while the listed corporate entity (Enertime SA) continues to exist.

Revenue is not publicly disclosed, but operational signals — 51–100 employees, a handful of named enterprise references per fiscal year, and project-based EPC/ESCO contracts — point to a sub-scale industrial OEM. Beyond its core machines, the company positions an innovation pipeline around hydrogen mobility, geothermal, stationary electricity storage, and marine thermal energy.

Core offering

Enertime designs and manufactures medium- and high-power thermodynamic machines — Organic Rankine Cycle (ORC) modules, industrial high-temperature heat pumps (PAC HT), and gas expansion turbines (turboexpanders) — that valorize industrial waste heat into electricity and useful thermal energy. These machines are sold either as standalone equipment or delivered through turnkey EPC contracts, supported by four tiers of operations & maintenance services and an ESCO third-party financing model that removes upfront capital expenditure for industrial customers.

Product overview

Enertime is a French industrial cleantech company specializing in thermodynamic machines for waste heat recovery and renewable energy production. The product portfolio centers on three core machine types: Organic Rankine Cycle (ORC) modules for converting waste heat into electricity, industrial heat pumps (PAC HT) for temperature elevation, and gas expansion turbines (turboexpanders) for natural gas pressure recovery. These systems are offered both as standalone equipment and through turnkey EPC contracts, supported by operations & maintenance services and innovative third-party financing (ESCO) arrangements. The company targets energy-intensive industrial sectors including glass, cement, steel, and waste incineration.

Functional benefit

Products and services

• Modules ORC (Organic Rankine Cycle) Organic Rankine Cycle modules that valorize medium- and high-temperature waste heat sources into electricity using a closed-loop thermodynamic cycle with an organic working fluid and proprietary turbine-alternator technology. Designed for energy-intensive industrial customers (glass, steel, cement, waste-to-energy, geothermal).
• Pompes à chaleur industrielles à très haute température (PAC HT) Industrial heat pumps that elevate the temperature level of low-temperature waste heat sources so they can be reused in industrial processes. Targeted at industrial sites seeking energy efficiency and decarbonization of heat demand.
• Turbines de détente de gaz (turboexpanders) Gas expansion turbines that valorize the energy released during natural gas pressure reduction at transport network interfaces, converting it into electricity and cooling. Targeted at natural gas distribution operators, gas processing, and oil & gas customers.
