India's industrial sector faces a critical decarbonisation challenge as it accounts for nearly half (approximately 50%) of the country's final energy consumption in 2025, with a substantial portion still dependent on fossil fuels. This issue is particularly acute for low-temperature process heat requirements (below 250°C), which form the operational backbone for sectors including textiles, food processing, chemicals, pharmaceuticals, and paper and pulp. A significant portion of this thermal energy demand is met through combustion of coal, oil, and gas, often within micro, small, and medium enterprises (MSMEs) that form the backbone of India's manufacturing ecosystem. The article examines industrial heat pumps as a practical, scalable, and modular technology solution for this challenge, highlighting their superior efficiency (Coefficient of Performance of 3-5), potential to reduce energy consumption by 40-60%, and co-benefits for worker health, air quality, and energy security. A case study of a Surat textile unit illustrates that 92% of its energy load was thermal, consuming 0.42 kg of Indonesian coal per meter of processed fabric.
India's industrial energy landscape has evolved within the broader framework of climate commitments and energy security concerns. Under the Paris Agreement, India submitted its Intended Nationally Determined Contributions (INDCs), committing to reduce emission intensity of GDP by 33-35% by 2030 from 2005 levels, with a significant portion of this reduction expected from the industrial sector.
The Bureau of Energy Efficiency (BEE) under the Ministry of Power has been central to industrial energy efficiency efforts. The Perform, Achieve and Trade (PAT) mechanism under the National Mission for Enhanced Energy Efficiency (NMEEE) has been operational since 2012, setting energy consumption norms for designated consumers across energy-intensive industries including textiles, cement, steel, and chemicals.

The renewable energy push gained momentum with the National Solar Mission (2010) and subsequent expansions, though solar focus remained primarily on electricity generation rather than industrial heat applications. The Green Hydrogen Mission (2023) represents the latest major policy push for hard-to-abate sectors.
[GK] The MSME sector, contributing approximately 30% to India's GDP and employing over 63 million people, has historically faced barriers in adopting clean technologies due to capital constraints, limited technical knowledge, and fragmented supply chains. The Production Linked Incentive (PLI) schemes launched from 2020 onwards attempted to address some manufacturing competitiveness concerns, with provisions indirectly supporting technology upgrades.
However, industrial process heat remained largely unaddressed in policy frameworks until recently. The article notes that conventional industrial thermal systems in factories are often designed around highest heat requirements, with boilers oversized for peak demand—a legacy approach that creates substantial inefficiencies.

Political & Constitutional Dimensions: The article connects industrial decarbonisation to India's international climate commitments under the Paris Agreement and its goal of achieving 500 GW non-fossil capacity by 2030. The political challenge lies in balancing emissions reduction targets with the need to maintain manufacturing competitiveness and support MSME livelihoods. The current government has prioritised self-reliance (Atmanirbhar Bharat) and domestic manufacturing, creating a potential tension between fossil fuel dependency for industrial heat and climate commitments. Opposition to aggressive transition stems from concerns about energy costs for price-sensitive MSMEs and potential job losses in traditional manufacturing. The constitutional dimension relates to Entry 53 of List III (Concurrent List) covering 'Coordination and determination of standards in big industries', which provides a basis for central energy efficiency standards. However, environmental protection (Entry 17, List II - State List) and factory welfare (Entry 26, List II) create overlapping jurisdictions.
Economic & Financial Impact: The economic case for heat pumps rests on their superior efficiency (COP 3-5) and potential 40-60% energy reduction, which can lower operating costs despite higher capital expenditure. The article notes that with renewable electricity available at competitive rates, heat pump-generated heat becomes cost-attractive even against conventional fuels currently. For MSMEs, however, capital constraints remain significant. The article suggests financing models specifically designed for smaller enterprises will be crucial. The geopolitical dimension is noteworthy: the Surat case study reveals reliance on Indonesian coal, highlighting vulnerability to volatile international commodity markets. Displacing fossil fuel imports through domestic renewable electricity for heat pumps could improve India's trade balance. However, upfront technology costs and disruption to existing supply chains pose economic transition challenges.
Social Dimensions: The article emphasises decarbonising industrial heat as 'not just a climate question but a socio-economic prerogative', with implications for air quality, cost competitiveness, energy security, and worker well-being. The 2.4 billion workers globally exposed to excessive heat, with highest rates in Asia-Pacific, represents a significant occupational health crisis. In India, fossil fuel air pollution caused 1.72 million premature deaths in 2022—making industrial transition a public health imperative. The article notes that electrified heating can improve thermal comfort in factory floors, addressing both climate adaptation and worker safety. However, transition costs may disproportionately affect smaller enterprises and informal workers. The article argues that by displacing on-site combustion, heat pumps can create opportunities for spot and space cooling, directly benefiting labour-intensive factory environments.
Governance & Administrative Aspects: Implementation challenges include retrofitting modular heat pump systems in brownfield MSME clusters where many boilers are old, oversized, and manually operated. The article emphasises that 'scaling industrial heat pumps will depend on how well they are embedded into existing industrial ecosystems through better process integration, reliable access to low-cost electricity, and financing models that work for industries, especially MSMEs.' Federalism implications exist: while the Centre sets energy efficiency standards through BEE, state industrial development corporations often drive MSME adoption. The challenge is creating financing mechanisms that work for fragmented MSME clusters that may lack collateral and credit history. Administrative capacity for technical assessment of heat pump suitability across different industrial processes remains limited. Standards and certification frameworks for industrial heat pump performance need development.
International Perspective: The article does not explicitly cite international policy models but the technology itself represents globally proven solutions. Countries like Denmark and Germany have significant industrial heat pump deployment, demonstrating technical feasibility. The International Energy Agency (IEA) has highlighted industrial heat pumps as a key decarbonisation pathway. However, India's context differs: higher proportion of MSMEs, lower electricity costs in some segments, and greater reliance on coal for industrial heat compared to European nations. The article's focus on Asia-Pacific as having highest workplace heat exposure rates contextualises India's challenge within the broader developing world experience where climate adaptation and mitigation must be pursued simultaneously.
