Bharat Heavy Electricals Limited has signed a Strategic Collaboration Agreement with Hystar AS, a Norwegian company, for Proton Exchange Membrane (PEM) electrolyser systems. The agreement, disclosed in a filing with stock exchanges on August 13, 2026, is designed to advance the company's green hydrogen initiatives by enabling phased indigenization and local manufacturing of these systems in India.
Agreement highlights
The key details of the strategic agreement are as follows:
| Parameter: | Details |
|---|---|
| Partner company: | Hystar AS |
| Partner country: | Norway |
| Technology: | PEM electrolyser systems |
| Purpose: | Green hydrogen projects |
| Nature: | International strategic tie-up |
PEM electrolysers are a critical technology in the production of green hydrogen, using electricity to split water into hydrogen and oxygen through a proton exchange membrane. This collaboration positions Bharat Heavy Electricals to access advanced electrolyser technology from Hystar AS, a specialist in this domain.
Strategic significance
The agreement underscores Bharat Heavy Electricals' focus on clean energy solutions, with green hydrogen emerging as a key area of interest in India's energy transition. By partnering with Hystar AS, Bharat Heavy Electricals aims to strengthen its capabilities in the green hydrogen value chain through the deployment of PEM electrolyser systems.
Notably, this deal complements a separate strategic tie-up Bharat Heavy Electricals entered into with thyssenkrupp nucera India Private Limited in July 2026 for alkaline electrolyser systems. This dual approach strengthens the company's position as one of the few Indian players capable of offering both alkaline and PEM electrolyser solutions to serve the country's emerging green hydrogen market.
The collaboration is expected to enhance Bharat Heavy Electricals' project execution capabilities for green hydrogen projects in India. It also aims to contribute to the National Green Hydrogen Mission and support the Government of India's Make in India initiative.
