Revolutionizing Solar Energy: CSIR-NAL's Eco-Friendly Breakthrough

CSIR-National Aerospace Laboratories recently transferred its innovative solar absorber coating technology, NALSUN-NG, to Helix Solar Private Limited. This step advances self-reliance in solar thermal technologies, aligning with national initiatives. NALSUN-NG, a graphene oxide-based water-friendly coating, promises local manufacturing and reduced imports, enhancing sustainable solar solutions in India.

CSIR-National Aerospace Laboratories (CSIR-NAL) has announced the successful transfer of its groundbreaking solar absorber coating technology, known as NALSUN-NG, to Helix Solar Private Limited, a burgeoning clean-tech startup located in Mysuru.

The formal agreement marks a significant step towards advancing self-reliance in solar thermal technologies, aligning with India's national initiatives such as Make in India, Atmanirbhar Bharat, and the National Solar Mission. This cutting-edge technology supports domestic production of flat plate solar water heaters, potentially curbing the monthly import of evacuated tube collectors.

NALSUN-NG represents a breakthrough in eco-friendly, water-based solar selective coatings made entirely in-house by CSIR-NAL. It addresses the challenges posed by traditional coatings that use harmful Volatile Organic Compounds (VOCs) by utilizing non-toxic inorganic materials. This innovation requires minimal infrastructure investment and is ideal for local manufacturing and rural deployment, steering India towards sustainable energy solutions.
