Coal Gasification and India’s Energy Strategy

The ongoing West Asian conflict in 2026 has triggered a global energy crisis. India faces shortages in domestic LPG supplies due to disruptions in Persian Gulf imports. This situation echoes the 1973 Oil Shock when OPEC cut oil exports, prompting India to explore alternative fuels. Coal gasification, a technique revived from earlier decades, is gaining renewed attention as a solution to energy security and climate goals.

Historical Background of Coal Gasification in India

Coal gasification was first proposed in India in 1955 by Syed Husain Zaheer, director of the Regional Research Laboratory Hyderabad. He envisioned producing fuel gas by gasifying indigenous coal types like lignite and bituminous coal. Zaheer’s plan included a national gas grid to supply fuel gas to cities and industries. Despite initial enthusiasm from Prime Minister Nehru, the project faced resistance from government bodies citing transport and economic concerns. Political and financial hurdles delayed pilot plants until the 1970s, when the 1973 Oil Shock revived interest.

Technology and Early Developments

The coal gasification process involves converting coal into fuel gas using high-pressure oxygen. Sulphur compounds are removed to produce clean gas. Early uses of coal gasification globally were for town gas lighting. India’s first pilot plant was delayed by wars and funding issues. By the 1980s, integrated gasification combined cycle (IGCC) technology was developed, combining coal gasification with electricity generation. Bharat Heavy Electricals Limited (BHEL) commissioned India’s first IGCC plant in 1985, using syngas to power turbines efficiently.

Recent Renewed Focus and Policy Initiatives

India launched the National Coal Gasification Mission in 2021 to gasify 100 million tonnes of coal by 2030. The mission aims to reduce dependence on imported natural gas and chemicals like methanol and ammonia. Investments of ₹85,000 crore have been committed. In 2024, Coal India Limited and BHEL formed Bharat Coal Gasification & Chemicals Limited to advance clean coal technologies. This marks a strategic shift towards utilising abundant coal reserves sustainably amid climate action pressures.

Challenges and Future Prospects

Despite technological progress, coal gasification faces challenges such as high capital costs and environmental concerns. Efficient removal of pollutants and integration with renewable energy are critical. The success of India’s coal gasification depends on strong policy support, industrial partnerships, and innovation. It offers a pathway to energy security while balancing climate commitments.
