India Green Hydrogen Assembly Opens in Greater Noida on 17 November

Two days in Greater Noida

The India Green Hydrogen Assembly, run alongside Hyvolution India, opens at the India Expo Mart in Greater Noida on 17 November and runs through 18 November. It is co organised by GH2 India and GL Events, with Apolto Events as the event host, and sits inside the wider Bharat Renewable Energy Summit calendar. The organisers' own listing names more than 150 exhibitors across over 14,000 square metres of floor, with sessions on electrolysers, green ammonia, hydrogen storage and fuel cell mobility. Confirmed speakers include officials from the Ministry of New and Renewable Energy and executives from NTPC Green Energy, L&T Energy GreenTech, ACME Group and AM Green, according to the event's own pages.

For a reader far from Delhi NCR, this is a trade show, not a public expo. Entry is by registration through the organiser's portal, with a Delegate Pass covering both days of sessions and lunch, and an Executive Delegate Pass adding the gala dinner and an executive breakfast. There is no word yet of a livestream for sessions.

What the mission's own numbers say

The timing matters more than the venue. Parliament got a fresh scorecard on the National Green Hydrogen Mission just three months before this show. In a written reply on 6 August 2026, Minister of State Shripad Yesso Naik told the Lok Sabha that the mission has spent ₹292 crore of its ₹19,744 crore outlay approved through FY2029-30.

Under the mission's SIGHT incentive scheme, the government has awarded 3,000 MW a year of electrolyser manufacturing capacity to 15 companies, and 756,100 tonnes a year of green hydrogen production capacity to 16 companies. That production number sits against the mission's own target of at least 5 million tonnes a year by 2030, a target the government itself has called a projection rather than a result.

A separate analysis of the same Parliament reply notes that as of July 2026 no electrolyser factory or hydrogen plant backed by SIGHT had been fully commissioned, which is why no incentive payment has actually gone out yet. Tranche I plants were due to start commissioning around August 2026, with Tranche II following by March 2027. That is the gap between the awards announced on stage in Greater Noida and hydrogen actually flowing.

The Bengaluru connection

India's electrolyser manufacturing base already has a Bengaluru address. Ohmium, which builds proton exchange membrane electrolyser stacks, runs a gigafactory at Doddaballapura on Bengaluru's outskirts, opened on 19 July 2024 with 2 GW of annual capacity and room to expand to 4 GW. It is exactly the kind of domestic manufacturing line the SIGHT scheme is designed to reward with per unit incentives once a plant is commissioned and verified. Whether Ohmium or any other Bengaluru supplier adds to the 15 companies already awarded electrolyser capacity is a number worth watching after this week's show, not before it.

Following it from India

There is no walk in entry. Anyone tracking this beat from outside Delhi NCR should watch the organiser's site and MNRE's own press page for outcomes from the two days, particularly any fresh SIGHT allocations or commissioning announcements timed to coincide with the show, since India's last official hydrogen numbers are now three months old.
