Why green hydrogen, why India, why now

India has moved from targets to signed contracts

Green hydrogen is no longer a policy aspiration in India. Production capacity has been awarded, electrolyser manufacturing is incentivised, and the components inside those electrolysers are still largely imported.

Three shifts

Why the window is open now

Localisation pays

SIGHT rewards domestic value addition in electrolyser stacks, and domestic value addition in alkaline diaphragms is close to zero today. An Indian separator is the fastest way for makers to raise it.

China+1 is real

China holds around 60% of global electrolyser manufacturing capacity. Buyers in India, Europe, the Gulf and the US are diversifying their supply chains and specifying on performance.

Suppliers are being chosen

The global market is consolidating. The winners will be the suppliers qualified into stacks over the next one to two years.

The separator is about 1% of an electrolyser's cost, but it sets the efficiency of the other 99%.

The build-out

A decade of electrolyser demand

Every megawatt of alkaline electrolysis needs roughly 150 m² of separator, plus replacements every 7–10 years.

Beyond India

Built in India, for the world

India's trade agreements with the UAE, EFTA, the UK and the EU lower barriers for Indian components, and international stack makers are looking for higher-performance components.

Middle East

Gulf

Hydrogen giga-projects and industrial parks building electrolyser capacity.

EU & EFTA

Europe

Stack makers specifying higher-performance, well-documented components, with EU FTA duty cuts from 2027.

Partners

Rest of world

Stack makers and projects served through partners and licensing.
