Reliance Industries Ltd is accelerating its clean energy ambitions with the rollout of a large-scale battery manufacturing plant by 2026, a massive solar energy project covering land three times the size of Singapore, and a goal of producing 3 million tonnes of green hydrogen annually by 2032. Speaking at the company’s annual general meeting for the first time, Anant Ambani, Executive Director and son of Chairman Mukesh Ambani, laid out the company’s vision to create one of the world’s most integrated renewable energy ecosystems — spanning solar modules, batteries, electrolysers, and green fuels like ammonia and methanol.
Reliance is investing in the entire clean energy value chain: from producing solar modules and energy storage systems to building electrolysers that use renewable electricity to generate hydrogen — seen as a key fuel for the future. The company also plans to produce sustainable aviation fuel and biofuels from organic waste for both domestic use and export.
“We are building platforms to deliver a comprehensive clean energy ecosystem — solar, battery storage, hydrogen — all at scale and under one umbrella,” said Anant Ambani. The products manufactured at these giga factories will support 24/7 renewable electricity supply and help produce green chemicals including green ammonia, e-methanol, and sustainable aviation fuels.
Jamnagar, already home to Reliance’s twin oil refineries — the world’s largest refining complex — is being transformed into the base for the company’s renewable energy ambitions. Construction of the Dhirubhai Ambani Giga Energy Complex is progressing rapidly and is expected to become the world’s largest clean energy hub in terms of scale and integration.
“Jamnagar will represent both the legacy of conventional energy and the future of new energy,” Mr Ambani said. Reliance has already begun producing solar photovoltaic modules at its Jamnagar facility. The company aims to scale up to a capacity of 20 GWp in the coming quarters, making it the largest single-site solar manufacturing facility in the world.
So far, it has successfully produced its first 200 MW of heterojunction (HJT) modules, which offer better performance and durability compared to conventional modules.
Alongside solar, the company is also building battery and electrolyser giga factories. The battery facility, scheduled to open in 2026, will start with an annual capacity of 40 GWh and expand to 100 GWh in phases. The electrolyser plant, also set to be operational by the end of 2026, will have the ability to scale up to 3 GW annually — supporting cost-effective hydrogen production on a global scale.
In Kutch, Gujarat, Reliance is developing one of the largest single-site solar projects in the world, covering 550,000 acres of arid land. At full pace, the site will deploy 55 MW of solar modules and 150 MWh of battery containers every day. Once complete, it could supply nearly 10% of India’s electricity demand within the next decade.
The company’s logistics and port infrastructure in Jamnagar and Kandla will support export operations for green hydrogen derivatives such as ammonia and methanol.
“India can become a global leader in affordable green hydrogen and its derivatives,” said Ambani, noting that the initial phase of production will serve the company’s own needs before scaling to 3 million tonnes per year by 2032.
Reliance is also focusing on bioenergy. It is building compressed biogas (CBG) plants with a target capacity of 0.5 million tonnes per year, aiming to scale to over 500 plants by 2030.
To support this, the company has set up the world’s largest Bioenergy Technology and R&D Centre in Jamnagar, where it is developing advanced technologies to increase biogas yields, including enzymes, microbes, and high-efficiency energy crops.
As part of its broader clean energy strategy, Reliance is also launching integrated energy hubs that combine smart farming, biogas and hydrogen production, agrivoltaics (dual land use for agriculture and solar power), and battery storage. These hubs aim to capture CO2 from CBG plants for green chemical production, targeting cost parity with fossil fuels.
This model creates threefold value for rural India: clean fuel, renewable power, and higher income for farmers. According to Mr Ambani, it has the potential to become a major growth engine for India’s renewable energy future.
