ReNew Power, one of India’s largest renewable-energy developers by installed capacity, has proposed a 2GW green hydrogen and ammonia project in the southwestern state of Kerala, according to reporting by Indian business newspaper The Economic Times.

The plant will reportedly be built in three phases with a combined production capacity of 1.1 million tonnes of ammonia (NH3), or 220,000 tonnes of H2, per year. The first phase will produce 100,000 tonnes of NH3 a year, with the following two phases 500,000 tonnes of annual capacity each.

Given each phase could take at least three years to build, the plant would start producing its first volumes of ammonia in 2027 at the earliest if a final investment decision is taken this year.

The full project, excluding the 5-6GW of renewables needed to power the 2GW electrolyser, is reportedly set to cost 264 billion rupees ($3.18bn).

The facility is set to be sited near the state-owned Vizhinjam deepwater port in the state capital Thiruvananthapuram, which is scheduled to complete construction on its first phase in May after years of delay.

The Economic Times had previously reported in July that an unnamed developer had proposed a green ammonia project near the port to export one million tonnes of NH3 to Germany a year.

However, this plant was set to produce 200,000 tonnes of H2 per year, powered by 1.2GW of solar backed up by 1.5GW of pumped hydro energy storage.

Hydrogen Insight has reached out to ReNew Power to confirm whether it has redesigned the plant since its initial proposal, or if reports from the summer refer to a different project of the same scale.

Last February, Kerala’s state government had allocated two billion rupees ($24m) in its budget to support the development of two hydrogen hubs in Thiruvananthapuram and Kochi.

The Indian federal government announced this month that it would hold an auction to subsidise 550,000 tonnes of green ammonia production a year.

ReNew had applied for subsidies in India's first national green hydrogen auction, alongside its joint venture partners Indian Oil and Larsen & Toubro, but failed to secure any funds when the winners were announced a few weeks ago.
