Anion exchange membrane company Versogen said it would jointly develop and commercialise stack and electrolyser solutions for India’s green hydrogen market with InSolare, after the Indian firm won subsidies for electrolyser making.

Under the deal, InSolare will license Versogen’s stack IP and know-how, while building up its own materials and design capabilities in India, with Versogen supplying its membrane technology and technical experience.

While the pair have not disclosed the deal’s value, InSolare plans to set up 250–300MW of manufacturing capacity, which could scale up to 1GW.

The company has been selected for Indian government subsidies covering 10MW of annual domestic electrolyser making, 19,000 tonnes of green hydrogen production, and 85,000 tonnes of green ammonia production.

InSolare founder and Director, Dr Hemanshu Bhatt, said the deal would help accelerate the adoption of green hydrogen while supporting India’s national hydrogen targets.

For Versogen, the agreement offers a low-capital route into an increasingly important market for electrolyser OEMs.

“India represents one of the most dynamic markets for green hydrogen,” said Dr Yushan Yan, CEO of Versogen. “Through this partnership with InSolare, we are bringing our patented PiperIon AEM technology to enable scalable, efficient, and affordable hydrogen production.”

The deal marks one of the company’s first major public partnerships since it scaled up its membrane manufacturing capacity to 1GW in 2023.

While AEM is seen as a promising electrolyser technology, it remains nascent compared to PEM and alkaline, with larger-scale commercial deployment limited.

Due to the lack of precious metals, there are still challenges related to the technology’s durability.
