New Delhi : Ostara Advisors, India’s first and leading specialist investment bank for deep-tech and sustainability, today released its 2026-2027 India Climate Tech and Deep Tech Deal Report. The report highlights that India’s climate-tech market is becoming more selective, with capital increasingly following energy security, domestic manufacturing, critical technologies and specific infrastructure bottlenecks.
With the climate narrative undergoing a strategic shift, energy security, domestic manufacturing, critical minerals, and deep-tech capabilities are becoming increasingly intertwined with the energy transition. At the same time, public and private capital is becoming more targeted towards addressing the key bottlenecks that determine the pace and scale of technology deployment. The report talks about emerging opportunities across storage, carbon markets, green hydrogen, nuclear power and the infrastructure supporting India’s AI and data-centre build-out, particularly firm renewable power, energy storage, grid equipment, cooling and water infrastructure.
The report has identified four areas that are likely to shape the next phase of investment: deep tech, energy storage, green-asset financing and energy-efficient data-centre infrastructure. It notes that companies between Series A and Series B are likely to encounter a deeper domestic investor base over the next 12–18 months as new India-domiciled growth funds and government-backed deep-tech capital develop.
The findings also highlight that India’s energy transition is entering a critical phase, with key regulatory milestones across carbon markets, solar manufacturing, green gas and EV localisation set to shape industry growth and investment decisions through FY27–FY28.
Commenting on the outlook, Vasudha Madhavan, Founder, Ostara Advisors, said, “India’s deep-tech and climate-tech sectors are approaching an important inflection point. The next phase of growth will depend not only on the availability of capital, but also on our ability to channel patient growth capital towards technologies that can be commercialized at scale. As domestic investment pools deepen and policy support for research, development and innovation evolves, opportunities are emerging across deep-tech manufacturing, energy storage and the wider energy-transition ecosystem. The focus for investors will be to distinguish promising innovation from businesses that can build durable commercial models and deliver long-term value.”
The full report, “Ostara Advisors Climate Tech and Deep Tech Review: 2026 in deals, and what 2027 looks like,” provides a detailed view of India’s climate-tech and deep-tech funding landscape, policy developments, value chains and 2027 outlook. The report reinforces the importance of a long-term investment approach to deep-tech and climate-tech, where technology development cycles can be extended and commercial outcomes depend on a combination of patient capital, execution capability and supportive market infrastructure.
