R&D is a key focus area at Triveni Turbines, enabling us to consistently gain newer competencies and strengthen our competitive edge in a technically challenging field. We continue to develop new turbines for our traditional smaller range as well as for medium and larger ranges for complex applications like API, geothermal and other niche sectors. These growing capabilities provide us with greater visibility into a broader market.

We are witnessing a growing demand for equipment that offers higher efficiencies while ensuring sustainable power generation. Aligned with this, we have pursued various new technologies and newer product introduction R&D programmes. Some of the key R&D programmes include:
Invested in optimising steam blade paths for enhancing their efficiencies and reducing cost, making our turbines more powerful, affordable, and market-ready to cater wide applications.
Industries globally are under pressure to ensure low-emission operations and achieve energy efficiency. Aligned with this, we have invested in the field of expanders, that go beyond conventional steam turbines by using alternative working mediums such as CO2, air, and hydrocarbons. We are engineering systems that can expand these gases to recover waste heat and convert it into power.
This opens opportunities in low-grade heat recovery, energy storage, and green industrial solutions, particularly relevant for sectors like steel, power, and chemicals. While we have successfully developed technology for CO2 indigenously, for complex gases like hydrocarbons, strategic partnerships are being evaluated to accelerate time-to-market.
Developed capabilities for supercritical CO2 (sCO2) turbine/power block as a more efficient and compact replacement for the steam‑Rankine cycle.
Developed Transcritical CO2 cooling skids and heating pumps with low global warming potential and coefficient of performance up to 6.
Developed thermal battery solution with CO2 as a low-cost capex and better opex alternative for addressing intermittency challenges of renewable power.
In FY 25, we successfully won an order for developing the first-of-its-kind CO2-based long-duration energy storage system (LDESS) in collaboration with our technology partner, Energy Dome.
The greenfield project involves designing, engineering, fabrication, erection, commissioning and testing a 160 MWh LDESS at NTPC's Kudgi Supercritical Thermal Power Plant premises. The unique system will use CO2 as a working fuel, undergoing a thermodynamic transformation in a closed loop to efficiently store energy.
This system will enable the storage and despatch of variable renewable power to stabilise the grid. This development showcases our collaborative efforts to prioritise local innovation and manufacturing. The engineered-to-order sub-critical CO2 turbine that will be used to power this ESS is indigenously developed and manufactured by us. The other storage system components would be largely manufactured and sourced from India.
