Quick Revision: The Scheme for Promotion of Surface Coal/Lignite Gasification Projects, with a ₹37,500 Crore outlay, aims to convert coal into syngas for cleaner energy and chemical production, aligning with India’s target of 100 MT coal gasification by 2030.

Why is this in the news?

The second round of the ₹37,500 Crore Scheme for Promotion of Surface Coal/Lignite Gasification Projects has concluded, receiving two applications from NTPC Limited. Concurrently, the third round of the scheme has been initiated, indicating a continued governmental impetus towards fostering cleaner coal technologies and diversifying India’s energy matrix through indigenous resources.

Background

• Coal gasification is a process that converts coal into a gaseous mixture known as syngas, which can be used to produce various chemicals, fertilizers, and power, offering a cleaner alternative to direct coal combustion.
• India possesses significant coal reserves, making coal gasification a strategic pathway to leverage domestic resources while mitigating environmental impacts associated with traditional coal usage.
• The government has set a target for 100 million tonnes (MT) of coal gasification by 2030, aiming to reduce reliance on imported natural gas and crude oil for various industrial applications.
• The Ministry of Coal has been actively promoting coal gasification projects through various initiatives, including financial incentives and policy support, to attract private sector investment and technological advancements.
• The scheme provides financial assistance for setting up surface coal/lignite gasification projects, thereby encouraging the adoption of advanced technologies and enhancing domestic production capabilities.
• NTPC Limited, a public sector undertaking, is a major power generation company in India and its participation underscores the commitment of state-owned enterprises to sustainable energy initiatives.

What is Coal/Lignite Gasification?

• Coal/Lignite gasification is a thermochemical process that converts coal or lignite into a gaseous mixture primarily composed of carbon monoxide (CO), hydrogen (H₂), and carbon dioxide (CO₂), along with trace amounts of other gases.
• This gaseous mixture, known as syngas (synthesis gas), is a versatile feedstock that can be used for a wide range of applications, including power generation, production of chemicals (e.g., methanol, ammonia), fertilizers (urea), and synthetic fuels.
• The process involves reacting coal/lignite with oxygen, steam, or air under high temperatures and pressures, breaking down the complex organic molecules into simpler gaseous components.
• Compared to conventional coal combustion, gasification offers several environmental advantages, such as lower emissions of sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and particulate matter, especially when combined with carbon capture and utilisation (CCU) technologies.
• It enables the efficient utilisation of low-grade coal and lignite, which might otherwise be difficult or uneconomical to use directly in power plants.
• The syngas produced can be cleaned and processed to remove impurities before further use, leading to cleaner end products and reduced environmental footprint.
• The scheme aims to incentivise the establishment of commercial-scale gasification plants, fostering technological innovation and creating a robust ecosystem for coal gasification in India.
• This initiative aligns with India’s broader energy transition goals, promoting a cleaner and more diversified energy mix while enhancing energy security through indigenous resource utilisation.
