Solarium Green Energy Ltd enters into Licensing Agreement for Transfer of Technology

Solarium Green Energy Limited ("SGEL" or "the Company") has entered into a Licensing Agreement for Transfer of Technology (LAToT) on September 02, 2025, with Armament Research & Development Establishment (ARDE), Pune Defence Institute of High Altitude Research (DIHAR), Leh, through its center Defence Research & Development Organisation (DRDO), Ministry of Defence, Government of India. The agreement pertains to the Transfer of Technology (ToT) of Solar Thermal Technology-based System for Space Heating of Shelters in Cold Conditions. The details and significance of this agreement are provided below.

Background and Significance of the Agreement

The severe cold conditions in high-altitude regions such as Ladakh, Uttarakhand, North-east region of India make indoor space heating essential for ensuring human comfort. At present, most heating requirements are met through conventional energy sources, which are finite and rapidly depleting. Moreover, the continued reliance on fossil fuels not only accelerates resource exhaustion but also contributes to atmospheric pollution and ecological imbalance. Rising CO₂ levels have already increased the earth's average temperature by about 1.5°C, and this trend continues upward. In Ladakh, space heating accounts for a substantial share of energy consumption in both residential and commercial buildings. Therefore, the adoption of a reliable, clean, energy-efficient, and cost-effective heating solution is of critical importance.

Defence Institute of High-Altitude Research (DIHAR), a lab of DRDO based in Leh, Ladakh has proposed a novel solar thermal energy based indoor space heating technology designed for indoor heating of shelters. The technology has proven successful in Ladakh because of the abundant sunshine available for over 310 days per year. This technology holds significant potential for defence shelters situated in high-altitude cold regions, where heating is typically reliant on kerosene or diesel boiler based indoor heating units. The newly developed system offers a sustainable alternative, with the capability to replace conventional methods.

DIHAR has already installed two such systems in Leh, which were tested extensively over three consecutive winters (2022, 2023, and 2024). Results demonstrate that the system performed effectively even during peak winter conditions, successfully replacing a diesel boiler-based heating setup that previously consumed 18 litres of diesel per hour to heat an office shelter.

The system is based on evacuated tube solar thermal collectors that harness solar energy, which is stored and delivered for space heating through thermic fluids and phase-change materials. For reliability, a heat pump unit is integrated as a backup source during cloudy or overcast days.

Following successful trials, DIHAR has proposed transfer of technology transfer (ToT) of this solar thermal heating system to industrial partners for wider commercialization. Solarium has submitted a bid for the ToT license and has been technically qualified to obtain the license for commercialization of this innovative technology.

Accordingly, Solarium has become one of the license holders for using such technology for manufacturing in India and sell in domestic market. This license has been granted for 10 years against the payment of INR 59,32,203 + Applicable GST for sales with end use of Indian Armed forces/other government agencies (Both Central & State/UT) only.

We have already received couple of projects and are also expected to receive more orders within the next couple of months in the region of Ladakh for installation in various locations of the Indian Army. with only Solarium and couple of other companies receiving this technology transfer, Solarium holds a unique, competitive advantage in a specialized, high-value market and are confident to scale up this business as separate segment over the next 2-3 years.

For doing such technical research & execution, Solarium hired Dr. Anshul Sachdeva who is Ph.D. holder from National Institute of Technology, Kurukshetra, India. Dr. Sachdeva brings extensive expertise in the fields of Solar Space Heating, Solar Cooling, Solar Cooking, and Phase Change Materials. He brings over 7 years of hands-on R&D experience in solar energy applications. His work includes collaborative projects with esteemed institutions such as DRDO, NISE, and ANRFDST, contributing to advancements in sustainable technologies. Dr. Sachdeva has been granted three patents for solar energy-based products by the Indian Patent Office. He has authored and presented 12 research articles in reputed international journals and conferences. In recognition of his work, he received the Best Research Paper Award at a National Conference in 2020. Dr. Sachdeva was awarded the prestigious Research Fellowship by the Science and Engineering Research Board (SERB)-now the Anusandhan National Research Foundation (ANRF) under the Department of Science and Technology (DST), Government of India. He has completed a DST-sponsored research project titled "Design and Development of Solar Assisted Solid Desiccant Air Conditioning System for India" at NIT Kurukshetra.
