Coal Gasification: Can India Turn Its Largest Fossil Fuel Reserve into an Industrial Advantage?

India has one of the largest coal reserves in the world, yet the country depends heavily on imported fuels. Around 82% of India’s crude oil and about 45% of its natural gas needs are met through imports, which makes the economy vulnerable to global price changes and supply disruptions.

Whenever global oil prices rise, India’s import bill increases sharply. This puts pressure on the country’s trade balance, currency, and inflation levels. Reducing this dependence has therefore become a key economic priority.

Coal gasification is now being explored as one possible solution. By converting coal into gas that can be used to produce fuels, fertilisers, and chemicals, the technology could help India use its domestic resources more effectively while lowering imports.

What is Coal Gasification?

Coal gasification is a thermochemical process in which coal reacts with oxygen and steam at high temperatures to produce synthetic gas (syngas). This gas typically consists of hydrogen, carbon monoxide, carbon dioxide, methane, and trace gases. Once produced, syngas becomes a versatile industrial feedstock that can be converted into a wide range of products, including:

• Methanol

• Ammonia and urea fertilisers

• Synthetic natural gas (SNG)

• Hydrogen

• Liquid fuels such as diesel and naphtha

The process effectively transforms coal from a traditional fuel used in power generation into a feedstock for chemical and industrial manufacturing. Synthetic natural gas produced from coal, for example, can substitute for imported LNG in certain industrial applications.

While gasification alone will not eliminate India’s energy imports, expanding this technology could help diversify the country’s energy sources and reduce exposure to global price fluctuations.

Methanol Production

One of the biggest opportunities linked to coal gasification is methanol production. Methanol is widely used in industries such as plastics, paints, chemicals, and fuels. Globally, methanol production capacity reached 161 million tonnes in 2021, with Asia being the largest producer and consumer. India currently consumes about 2.5 million tonnes of methanol every year, but nearly 90% of this demand is met through imports.

Coal gasification could significantly change this situation by enabling large-scale domestic methanol production. This would reduce imports while supporting the growth of manufacturing industries that depend on chemical feedstocks. According to policy estimates, blending 15% methanol in petrol could reduce India’s gasoline imports by around 1-5%, lowering the country’s crude oil import burden while also reducing emissions.

To support this shift, NITI Aayog’s Methanol Economy programme encourages the use of methanol as a transport fuel and industrial feedstock.

Policy Support and Industrial Participation

The Indian government has launched the National Coal Gasification Mission to promote this technology. The goal is to achieve 100 million tonnes of coal gasification capacity by 2030. Reaching this target will require investments of more than ₹4 trillion, making it one of the largest upcoming investments in India’s energy sector.

To encourage companies to participate, the government has introduced several incentives, including financial support and concessions on coal used for gasification projects. These measures are meant to attract private investment and accelerate the development of coal-to-chemical and coal-to-fuel projects.

Several major companies have begun exploring coal-to-chemicals and coal-to-gas projects.

Key participants include:

• Coal India Limited

• NTPC Limited

• Reliance Industries

• GAIL

• Adani

• BHEL

These projects aim to integrate coal resources with chemical and fuel production, potentially creating new industrial clusters centred on coal-based feedstocks.

Lessons from China

Several countries have already adopted coal gasification on a large scale, most notably China. Coal-to-chemicals technologies have enabled China to develop large domestic industries for methanol, ammonia, and petrochemicals. China now represents more than half of the world’s methanol production capacity, with a significant portion derived from coal gasification. Around 70% of China’s methanol production is coal-based, demonstrating the economic viability of the technology when implemented at scale.

This experience highlights the potential for coal gasification to support large industrial ecosystems while improving energy self-sufficiency.

Technology and Domestic Innovation

While coal gasification offers strong economic potential, one challenge lies in the nature of Indian coal. Much of India’s coal contains high ash content, upto 45%, which makes it harder to process using conventional technologies.

Indian research institutions and companies are therefore developing technologies suited to local coal characteristics. A collaboration between IIT Delhi and Thermax has already demonstrated the production of methanol from high-ash Indian coal in pilot trials. Public sector companies such as BHEL are also working on gasification systems designed for Indian conditions.

These developments suggest that India is gradually building domestic technological capability, which could reduce reliance on imported systems as the industry expands.

Market Implications for Investors

Coal gasification could influence several sectors of the Indian economy.

1. Coal producers may benefit from new demand beyond power generation, as coal becomes a feedstock for chemical production.

2. Fertiliser companies could gain from greater availability of hydrogen used in ammonia production, potentially lowering reliance on imported natural gas.

3. Petrochemical companies may also benefit if coal-based methanol production expands domestically.

4. Gasification could contribute to India’s emerging hydrogen sector, particularly through blue hydrogen production when combined with carbon capture technologies.

What It Means for the Economy

Coal gasification could create a new industrial value chain:

Coal → Gas → Chemicals → Fertilizers → Fuels → Manufacturing

Each stage supports industries that generate jobs, investment, and economic activity. Large gasification plants located near coal mines could also stimulate regional development by attracting supporting industries and infrastructure.

In an era of volatile energy markets and rising import bills, coal gasification may represent India’s attempt to convert its most abundant fossil resource into a strategic industrial advantage linking energy security with manufacturing growth and economic resilience.
