What Happened

Industry accounts for nearly half of India's final energy consumption as of 2025, with a large share still dependent on fossil fuels for process heat — making industrial heat one of the hardest-to-abate sectors in India's decarbonisation roadmap.
Industrial heat pumps are emerging as a commercially viable "clean heat" technology that can electrify low- to medium-temperature industrial processes (up to ~200°C), replacing gas boilers and coal-fired steam systems.
Decarbonising industrial heat addresses four inter-linked national priorities simultaneously: climate action, air quality improvement, energy security, and industrial competitiveness.
India's carbon market is preparing for compliance trading in the second half of 2026, creating a financial incentive for industries adopting low-carbon heat technologies.
A real-world example: DCM Shriram installed a steam-generating industrial heat pump developed by TRIGeN DC at its sugar plant in Hariawan, Uttar Pradesh (2022), demonstrating the technology's viability in Indian industrial conditions.
India's rapid infrastructure buildout — its urban population is set to double by 2050, requiring vast additional capacity in cement, steel, textiles, and chemicals — means that decisions taken now on heat technology lock in emissions profiles for decades.

Industrial Heat Pumps — How They Work

A heat pump uses mechanical work (electricity) to move heat from a low-temperature source (ambient air, wastewater, exhaust streams) to a higher-temperature sink (process steam, hot water, drying air). Unlike a boiler that generates heat by burning fuel, a heat pump transfers existing heat, making it 3–5 times more energy-efficient than direct electric resistance heating or gas combustion. This efficiency ratio is measured by the Coefficient of Performance (COP): a COP of 3 means 3 units of heat delivered for 1 unit of electricity consumed. Industrial heat pumps currently operate at temperatures up to 200°C, suitable for a wide range of manufacturing processes.

Coefficient of Performance (COP): Ratio of heat output to electricity input; industrial heat pumps achieve COP of 1.6–5.8 depending on temperature lift
Temperature lift: The difference between the heat source and heat sink temperature; smaller lift = higher COP
Practical temperature range: 80°C–200°C for industrial applications (low to medium heat demand)
High-temperature applications: Above 150°C — required for paper, food processing, chemical sectors — currently at the frontier of commercial deployment
Working refrigerants: R245fa (common), CO2 (transcritical, can reach 210°C with COP ~2.14), ammonia
Key sectors for deployment: Food and beverage, dairy, textiles, chemicals, pharmaceuticals, sugar refining, pulp and paper

Connection to this news: India's industrial processes in food processing, textiles, and chemicals — sectors with massive employment — predominantly operate at temperatures below 150°C, making them prime candidates for heat pump adoption where the technology is already commercially proven.

India's Industrial Energy Profile and Decarbonisation Challenge

Industry is India's largest energy-consuming sector, accounting for approximately 40–45% of final energy consumption. Within industry, process heat (steam, hot air, direct heat for drying, curing, and chemical reactions) constitutes the largest single energy end-use. The majority of this heat is generated by burning coal, natural gas, biomass, and furnace oil. Unlike electricity generation (where solar and wind can substitute at scale), industrial heat cannot be easily replaced through the grid alone — it requires either fuel-switching (green hydrogen, biofuels), electrification (heat pumps, electric boilers), or efficiency improvements.

India's industrial energy share: ~45% of total final energy consumption (2025)
Process heat share: ~60–70% of industrial energy demand
Current fuel mix for industrial heat: Coal (dominant), natural gas, biomass, oil
Hard-to-abate sectors: Steel (blast furnaces at 1,500°C+), cement (1,450°C kilns), aluminium smelting — not amenable to current heat pump technology
Amenable sectors: Food processing, textiles, dairy, chemicals, pharmaceuticals, sugar — operate at 60°C–150°C

Connection to this news: The article's argument is that while high-temperature industrial decarbonisation (steel, cement) requires breakthrough technologies like green hydrogen, there is an immediately deployable solution available for low-to-medium temperature heat — industrial heat pumps — that India has been slow to adopt.

India's Carbon Market — The Carbon Credit Trading Scheme (CCTS)

India's carbon market is being developed under the Energy Conservation (Amendment) Act, 2022, which created the legal framework for a domestic Carbon Credit Trading Scheme (CCTS). The Bureau of Energy Efficiency (BEE) under the Ministry of Power is the implementing body. The scheme will initially cover large industrial units in energy-intensive sectors (steel, cement, pulp and paper, petrochemicals, textiles, chlor-alkali, aluminium) and is slated to move to compliance-based trading (mandatory caps with tradeable credits) in the second half of 2026. Before compliance trading, entities reducing emissions below sector benchmarks can earn Indian Carbon Credits (ICCs) and trade them.

Legal basis: Energy Conservation (Amendment) Act, 2022 (amended Energy Conservation Act, 2001)
Nodal body: Bureau of Energy Efficiency (BEE), Ministry of Power
Scheme: Carbon Credit Trading Scheme (CCTS)
Phase 1 (voluntary/offset): 2023–2025; Phase 2 (compliance): targeted from H2 2026
Covered sectors: Steel, cement, aluminium, petrochemicals, textiles, pulp and paper, chlor-alkali
Credit unit: Indian Carbon Credit (ICC) — 1 ICC = 1 tonne CO2 equivalent reduced
Trading platform: Indian Carbon Market (ICM) — to be operated through power exchanges

Connection to this news: As India's carbon market moves to compliance-based trading in 2026, industries that adopt industrial heat pumps and electrify their process heat will be able to monetise their emission reductions through Indian Carbon Credits — significantly improving the financial case for heat pump adoption.

India's Climate Commitments — NDCs and Net Zero Target

India submitted its updated Nationally Determined Contributions (NDCs) under the Paris Agreement in August 2022, committing to: (1) reduce the emissions intensity of GDP by 45% by 2030 (from 2005 levels); (2) achieve 50% of cumulative electric power installed capacity from non-fossil-fuel-based energy resources by 2030; and (3) create an additional carbon sink of 2.5–3 billion tonnes of CO2 equivalent through forests and tree cover by 2030. India has also announced a Long-Term Low Emission Development Strategy (LT-LEDS) targeting net zero emissions by 2070.

India's NDC targets (updated 2022): 45% emissions intensity reduction by 2030; 50% non-fossil electricity capacity by 2030
Net zero target: 2070 (announced at COP26, Glasgow, November 2021)
Industrial sector's role: Needs to reduce absolute emissions while allowing economic growth — making efficiency and fuel-switching critical
Energy Conservation Act, 2001 (amended 2022): Empowers BEE to set energy norms; now also covers green hydrogen standards and carbon markets

Connection to this news: Industrial heat decarbonisation — if achieved at scale via heat pumps — directly contributes to India's NDC target on emissions intensity and supports the trajectory toward the 2070 net zero goal, particularly for the large segment of industry operating at sub-200°C temperatures.
