From oil to green power: Reliance bets on the world’s largest clean energy hub


Reliance Industries Ltd is accelerating its pivot away from fossil fuels with a sweeping clean energy strategy. The company plans to launch a mega battery manufacturing plant by 2026, build a solar power project larger than Singapore, and achieve 3 million tonnes of green hydrogen capacity by 2032.

Making his first appearance at Reliance’s Annual General Meeting, Anant Ambani — the youngest son of chairman Mukesh Ambani and executive director of the company — outlined a vision to create the world’s most integrated new energy ecosystem, spanning “from sand to electrons to green molecules.”

Fully Integrated Green Energy Platform

Reliance is investing in every link of the clean energy chain:

  • Solar modules to generate electricity from sunlight.
  • Advanced batteries to store renewable power.
  • Electrolysers to produce green hydrogen by splitting water molecules.
  • Giga factories to manufacture hydrogen and its derivatives, including green ammonia, green methanol, and sustainable aviation fuel.
  • Biofuels derived from organic waste.

According to Anant Ambani, these facilities will enable round-the-clock renewable energy supply and support both domestic use and exports of clean fuels.

The centrepiece of this transformation is the Dhirubhai Ambani Giga Energy Complex in Jamnagar, already home to Reliance’s massive oil refining operations. Once complete, it will be the world’s largest integrated clean energy hub, producing solar modules, batteries, and hydrogen derivatives at unparalleled scale.

Reliance has already started scaling its solar PV manufacturing line at Jamnagar to 20 GWp capacity, which would make it the largest single-site solar facility in the world. The company has rolled out its first 200 MW of high-efficiency HJT modules, which offer higher energy yields and lower degradation compared to conventional panels.

In parallel, construction of battery and electrolyser giga factories is underway. The battery plant, set to start production in 2026, will begin with 40 GWh annual capacity and eventually expand to 100 GWh. The electrolyser facility, also targeted for 2026, will scale up to 3 GW per year and enable globally competitive hydrogen production.

Mega projects in Gujarat

Reliance’s clean energy ambitions are concentrated in Gujarat. In Kutch, the company is developing one of the world’s largest single-site solar projects, covering 550,000 acres — nearly three times Singapore’s land area. At peak installation, Reliance expects to deploy 55 MW of solar modules and 150 MWh of battery containers per day. Within a decade, this single project could meet nearly 10% of India’s electricity demand.

The Jamnagar and Kandla ports will provide the critical infrastructure backbone, enabling Reliance to export green ammonia, e-methanol, and sustainable aviation fuel. By 2032, the group aims to produce the equivalent of 3 million tonnes of green hydrogen annually, establishing India as a hub for affordable clean fuels.

Beyond solar and hydrogen, Reliance is scaling its compressed biogas (CBG) operations. The company has set an ambitious target of over 500 CBG plants by 2030, with a combined capacity of 0.5 million tonnes per year. At its Bioenergy Technology and R&D Centre in Jamnagar, Reliance is developing next-generation enzymes, microbial solutions, and high-yield crops to enhance biogas productivity.

Anant Ambani also highlighted the company’s agrivoltaics model, which integrates solar and biogas production on the same land. By capturing carbon dioxide from CBG plants, these hubs will become centers for producing green chemicals. The approach, he noted, delivers a “triple value” — generating renewable gas, electricity, and boosting rural incomes for farmers.
