Heat Pumps: The Future of Fossil-Free Industrial Steam
Steam remains a foundational element in countless industrial processes—from sterilization in pharmaceuticals and cooking in food processing, to dyeing in textile units and more. However, most of this industrial heating occurs at temperatures below 200°C, and unfortunately, the majority of this steam is still generated using fossil fuels like coal, diesel, and gas.
These conventional systems are carbon-intensive, cost-volatile, and increasingly incompatible with India’s decarbonisation goals. But there is now a technically superior and economically viable solution already available and scalable: the industrial heat pump.
Why Traditional Steam Systems Are Unsustainable
Today’s industrial boilers run on fossil fuels, delivering steam but at a heavy cost—both environmental and economic:
- Low energy efficiency: Fossil fuel boilers have a Coefficient of Performance (COP) of just 0.65.
- High emissions: They are one of the top contributors to Scope 1 industrial emissions.
- Rising fuel prices: Coal, diesel, and gas prices are volatile due to geopolitical tensions and global inflation.
- Regulatory & ESG pressure: Stricter mandates from governments and global buyers are pushing for cleaner supply chains.
Heat Pumps: The Smart, Clean Alternative
What is a Heat Pump?
Heat pumps transfer ambient heat or waste heat from a low-temperature source and upgrade it to deliver high-grade heat or steam up to 180–200°C, suitable for most industrial processes in India.
Why Heat Pumps Are Technically Superior
Higher Efficiency
Heat pumps transfer ambient heat or waste heat from a low-temperature source and upgrade it to deliver high-grade heat or steam up to 180–200°C, suitable for most industrial processes in India.
- A heat pump typically delivers a COP > 3, which means for every unit of electricity consumed, it provides 3+ units of heat energy.
- In contrast:
- Fossil boilers: COP ≈ 0.65
- Electric boilers: COP ≈ 0.9 – 0.95
- Fossil boilers: COP ≈ 0.65
Wide Temperature Compatibility
- New-generation industrial heat pumps can reach temperatures up to 200°C, covering the majority of industrial steam applications.
Unbeatable Cost Advantage
When compared to other steam generation options, heat pumps offer the lowest per-kg cost of steam:
| Steam Source | COP | Electricity/Fuel Cost | Steam Cost (₹/kg) |
|---|---|---|---|
| Heat Pump (₹8/unit power) | >3 | ₹8/unit | ₹2.60/kg |
| Heat Pump + Renewable Power | >3 | ₹5.5/unit | ₹1.70/kg |
| Coal/Biomass Boilers | 0.65 | Variable | ₹4.00 – ₹4.50/kg |
| Electric Boiler | 0.95 | ₹8/unit | ₹8.50/kg |
Conclusion: Heat pumps are not just more sustainable, they are significantly more economical.

Supporting Technologies (Complementary but Secondary)
While heat pumps are the most energy-efficient and sustainable path to decarbonisation, certain scenarios may require hybrid or supplementary solutions:
- Biomass Boilers: Viable in rural/agro-industrial setups, but require space and emissions control.
- Solar Thermal: Good for low-temp applications; intermittent and space-intensive.
- Waste Heat Recovery: Enhances overall system efficiency; useful in combination with heat pumps.
However, none match the system-wide efficiency and cost savings of heat pumps.
The Path Forward: Why Heat Pumps Must Lead the Transition
India’s industrial sector is under growing pressure to cut emissions, control energy costs, and comply with ESG mandates. For steam applications under 200°C—which make up the vast majority of use cases—heat pumps are the clear solution.
They deliver:
- Lower emissions
- Lower steam costs
- Lower energy use
- Faster ROI
- Higher ESG scores
