India continues to depend heavily on coal for energy security amidst rising electricity demands and international pressure to cut carbon emissions. While experts advocate for a shift towards cleaner coal technologies and greater efficiency in thermal plants, significant challenges remain in achieving this transition.

India's Coal Conundrum: Balancing Energy Security and Environmental Responsibility
As India's demand for energy surges, reliance on coal raises pressing questions about decarbonization and the future of cleaner energy solutions.
India's reliance on coal remains a critical component of its energy strategy, with the country asserting its necessity for energy security and developmental goals. Despite international climate agreements advocating the phasing out of coal, energy experts and environmental advocates suggest a focus on decarbonizing coal-fired power plants. Ashok Lavasa, a former government secretary, encapsulated this dilemma, questioning if coal can be a "benevolent king" in India's energy landscape.
The context for India's steadfast commitment to coal lies in the escalating electricity demands fueled by rapid economic growth. Predictions indicate that electricity consumption may double by 2030, with coal-fired plants continuing to supply over 70% of the nation's total electricity needs. This reliance results in a staggering contribution of more than 40% to India's annual carbon emissions, predominantly from coal.
Progress has been made in renewable energy, which now constitutes 46% of India's installed capacity. However, the intermittent nature of renewable sources like solar and wind poses challenges for consistent energy supply. Without significant advancements in energy storage capability, thermal energy remains an essential foundation for India’s power grid stability.
Grid India’s Rajiv Porwal highlighted that misalignments between electricity demand and supply could expose the grid to risks, including power cuts akin to recent episodes witnessed in Spain. Therefore, India's approach appears to focus on reducing emissions from existing coal power plants rather than pursuing an outright coal exit. A report from the Centre for Science and Environment (CSE) suggested that emission reductions from coal could decrease greenhouse gases by 30%, aligning with India's commitment to reduce emissions intensity by 45% by 2030.
Yet, challenges persist, particularly regarding coal plant operations which must maintain a minimum capacity regardless of renewable outputs. Achieving greater efficiency in thermal plants is crucial, prompting calls for technological advancements that might capture carbon emissions—a process currently limited in effectiveness.
Other proposals include substituting coal with agricultural waste in certain regions, which has reportedly decreased coal usage in the Delhi area. However, widespread adoption of this approach has been sluggish in other parts of the nation.
Ultimately, the transition towards cleaner coal technologies and greater efficiency will require extensive systemic changes, which come with substantial financial implications. The specifics of these costs, who will absorb them, and the timeline for achieving reductions in emissions remain significant barriers to progress in India's energy landscape.
