India-based CleanTech startup Promethean Energy has raised US$2 million in a pre-series A round led by Transition VC, with participation from Sangam Venture, Sagana Capital, and Fondation Botnar.

The company will use the funds to expand product offerings, scale operations, and strengthen its presence in India and Southeast Asia.

Founded by IIT Bombay alumni, Promethean Energy develops industrial heat pump systems and waste heat recovery solutions to cut fossil fuel use in manufacturing and commercial sectors.

Its systems are used in industries like automotive, FMCG, chemicals, textiles, and steel, with clients including Hindustan Unilever, Godrej Industries, and Raymond Textiles.

The company reports saving over 100,000 tonnes of CO2 emissions annually. It aims to decarbonize 1,000 factories by 2027 and plans to launch pilot projects in Bangladesh and Indonesia.

🧠 Food for thought

1️⃣ India’s industrial decarbonization represents a $15+ billion market opportunity

Industrial thermal energy remains heavily dependent on fossil fuels in India, creating both an environmental challenge and business opportunity for solutions like Promethean’s heat pumps.

India ranks as the third-largest global carbon emitter, with industrial sectors contributing approximately 10% of national emissions according to the original article.

The country’s ambitious target to achieve net-zero emissions by 2070, alongside a 45% reduction in GDP emission intensity by 2030, is driving policy support for clean energy technologies 1.

This regulatory push combines with market forces to create substantial growth projections, with the broader industrial energy efficiency market expected to expand from $27.28 billion in 2025 to $48.6 billion by 2032 at an 8.6% CAGR 2.

Promethean’s focus on replacing fossil fuel-based heating with electric alternatives directly addresses one of the most difficult-to-decarbonize aspects of industry, positioning them in a high-growth segment.

The company’s claim of payback periods twice as fast as global alternatives highlights how locally-adapted solutions can accelerate adoption in price-sensitive industrial markets.

2️⃣ The rise of specialized climate tech funding in India signals ecosystem maturity

Promethean’s funding round, led by Transition VC, reflects the emergence of specialized investors focused exclusively on energy transition technologies in India.
