GH2 AHES — Joint Venture

GH2 Solar and AHES have established GH2 AHES, a strategic joint venture operating as a green hydrogen electrolyser OEM for the Indian market. This collaboration merges South Korean technical brilliance with our local expertise as a green energy EPC contractor in India to drive industrial decarbonisation.

Sustainable Hydrogen Technology

We use alkaline electrolyser units featuring durable, non-precious metal catalysts, which help us drastically cut down on total production costs.

Electrolyzer Manufacturing Facility in India

Our team is developing a state-of-the-art hub intended to power domestic green hydrogen production and reinforce the national supply chain.

Skill Development and Employment

This venture creates specialised jobs that directly fuel India’s transition toward stationary fuel cell power systems and clean, local manufacturing hubs.

Driving the Green Hydrogen Ecosystem

By working with global technology partners like AHES, GH2 Solar is building the infrastructure for a green hydrogen developer ecosystem that actually scales. We combine international fuel cell technology with our expertise as solar EPC contractors to accelerate innovation and the shift toward a sustainable hydrogen power plant in India.
