India's Green Energy Transition

The Central Electricity Authority (CEA) has recently released guideli­nes on medium- and long-term demand forecasting, aiming to address the non-uniformity in forecasting app­roa­ches used by various states and utilities. While these guidelines offer clarity on major aspects, some issues need to be resolved for effective implementation.

In India, emissions from one truck are equivalent to those from 25 cabs. With the expected increase in economic activity and consumerism, the share of trucks in transportation emissions is bound to increase. Thus, freight decarbonisation is crucial to meet India’s net-zero and energy independence targets.

India's commitment to the EV30@30 initiative that targets at least30% of vehicle sales to be electric by 2030 translates into adding24 million two-wheelers, 2.9 million three-wheelers, and 5.4 million four-wheelers to its EV fleet by 2035. To meet this demand and reduce its reliance on global EV-component markets, India requires around 3,400-4,100 GWh of lithium-ion batteries (LIBs) by2035, estimates the International Council on Clean Transportation.

In early September, India's peak daytime electricity demand stood at 241 GW, a record high. The solar market in India plays a crucial role in meeting this ever-increasing demand, especially the rooftop photovoltaic sector which has enormous untapped potential. The Government of India aims to have 40 GW of rooftop photovoltaics (RTPV) installed capacity by March 2026.

So far in this series, we discussed different aspects of India’s solar PV sector, including taxation, policies, and the journey towards sustainability. In this concluding piece, we focus on popular technologies, innovations, challenges, and opportunities.

India’s solar photovoltaics (PV) market is rapidly growing. However, to reach the ambitious goal of 500 GW of renewable energy by 2030, there is a pressing need to increase installed capacity and generation targets. With only around 62 GW of installed solar capacity achieved by the end of 2022, India fell short of its 100 GW target for the year. Favourable policies, financial support, technological advancements, and a competitive market are essential for further advancing the growth of India’s solar PV sector.

In the previous article, we discussed the gaps in key areas that hamper the sustained growth of India’s solar PV market. In this article, we shift our focus to two critical aspects that are influencing the sector - ALMM and BCD.

In 2021, Hanson — a subsidiary of Heidelberg Cement in the United Kingdom — substituted 100% of thermal energy with energy from alternative fuels in one of its cement kilns by using a mixture of hydrogen (39%), glycerine (49%), and meat and bone meal (MBM; 12%) instead of coal. This is the world’s first usage of 100% climate-neutral fuel and one of the first demonstrations of hydrogen-based technology in the cement kiln. Such adaptations, comprising a climate-neutral fuel blend, in the Indian cement industry remain elusive, even in 5% of the plants.

India’s wind capacity target for 2030 is 140 GW, and the current wind installation achieved until April 2023 is 42.8 GW. To achieve the remaining 98 GW, considerable growth rate and comprehensive efforts are needed in the coming years. India has a total wind energy potential of 695GW at 120 metres (National Institute of Wind Energy), which is on par with the solar energy potential of 748GW (National Institute of Solar Energy).

India generates an enormous amount of waste, including municipal solid waste (MSW), industrial waste, hazardous waste, and biological waste. According to the State of India's Environment 2023 report, MSW generation in India is estimated to be around 150,000 tonne per day (TPD). To harness the energy potential of this waste and reduce reliance on landfills, waste-to-energy (WTE) processes are being explored across India.
