A net-zero emissions energy system in India by 2050: An exploration

This study examines whether adequate opportunities exist for full decarbonisation of the Indian energy sector and highlights where enough choices for full decarbonisation by 2050 do not exist. The study suggests transformative levels of electrification, energy efficiency improvements, and a switch towards decarbonised fuels (largely green hydrogen, decarbonised electricity, and bioenergy) as the three mainstays of India's decarbonisation strategy that could plausibly shift the energy sector towards a net-zero emissions future. The study also indicates that the heavy freight and industrial sectors face challenges in achieving full decarbonisation because of a lack of adequate technological solutions. Accordingly, residual emissions of about 1.3 gigatonnes in the system would require carbon sequestration options, including both technological and nature-based solutions, to achieve net-zero emissions. This study is expected to encourage further deliberations and deep dives into energy sub-sectors, which would benefit planners and policymakers in delineating India's sustainable energy transition strategy.

Automated summary

This study examines the opportunities for full decarbonisation in the Indian energy sector and identifies areas where achieving full decarbonisation by 2050 is not currently possible. The study suggests transformative levels of electrification, energy efficiency improvements, and a shift towards decarbonised fuels as key strategies for achieving net-zero emissions in India. However, challenges exist in the heavy freight and industrial sectors due to a lack of adequate technological solutions.
