Industrial Heat Electrification: Context and Background
- Industry accounts for approximately 35% of India’s total energy consumption.
- Industrial heat processes contribute nearly 25% of India’s total CO2 emissions.
- India has committed to net zero emissions by 2070 under its updated NDC framework.
- Most industrial heat currently comes from coal, natural gas, furnace oil and biomass combustion.

Key Aspects of Industrial Heat Electrification
Heat Temperature Classification
- Industrial heat is classified as low heat (below 150°C), medium heat (150-400°C) and high heat (above 400°C).
Electrification Pathways by Heat Band
Low Heat
Readily electrifiable today for food processing, textiles, pharmaceuticals and packaging.
Heat Pumps
Deliver low and medium temperature heat at 3-5 times the efficiency of direct fossil fuel combustion.
Electric Boilers
Commercially available and cost-competitive for steam generation below 250°C already.
Induction & Infrared
Offer precise temperature control and higher energy efficiency than conventional combustion systems.
- Medium Heat Applications: Chemicals, paper, rubber and food processing sectors can transition to medium heat electrification with available technology.
High-Heat Challenge and Green Hydrogen
- High Heat Challenge: Steel, cement, glass and ceramics require above 1000°C heat, where electrification remains technically difficult and costly.
- Green Hydrogen Role: A promising decarbonisation option for high-temperature industrial processes where direct electrification is not feasible.
⚠️
Challenges in Scaling Industrial Heat Electrification
- High Capital Cost: Replacing existing fossil fuel boilers and furnaces with electric systems requires significant upfront capital expenditure.
- Grid Reliability: Industrial processes need 24×7 reliable electricity supply, but grid reliability remains inconsistent across Indian states.
- Electricity Tariff: Industrial electricity tariffs in India are significantly higher than comparable fossil fuel costs, reducing competitiveness.
- High Heat Barrier: Technologies for electrifying above 800°C processes are not yet commercially mature at industrial scale.
- SME Financing Gap: Small and medium enterprises lack access to affordable financing for capital-intensive electrification transitions.
- Skilled Workforce Deficit: Operating electric heat systems requires different technical skills than fossil fuel systems, creating workforce transition challenges.
- Supply Chain Gaps: Domestic manufacturing of heat pumps, electric boilers and induction heating systems is limited, increasing import dependence.

Way Forward for Industrial Heat Electrification
Common Blueprint
Develop a national industrial heat electrification roadmap with sector-specific targets and technology pathways.
Electricity Tariff Reform
Rationalise industrial electricity tariffs to reflect renewable energy’s true cost, improving electrification economics.
Green Industrial Zones
Establish dedicated green industrial zones with reliable 24×7 renewable power supply for electrification-ready industries.
Technology Mission
Launch a Mission for Industrial Heat Electrification under the National Mission for Enhanced Energy Efficiency.
SME Support
Create dedicated financing windows and subsidised loans for SME heat electrification through SIDBI and green bonds.
Domestic Manufacturing
Incentivise domestic manufacturing of heat pumps and electric boilers under Production Linked Incentive schemes.
BEE Standards
Mandate Bureau of Energy Efficiency standards for new industrial heat equipment, promoting high-efficiency electric systems.
Green Hydrogen Push
Accelerate the National Green Hydrogen Mission to decarbonise high-temperature processes where electrification is not feasible.
Industrial heat electrification is not a distant aspiration — it is economically viable today for many sectors. Low and medium temperature industries face no technical barrier, only financing and policy barriers. A common blueprint aligning electricity pricing, technology standards and financing will unlock India’s industrial decarbonisation potential.
