DST develops durable battery for remote sub-zero conditions

Scientists from the Department of Science and Technology (DST) have developed an efficient, durable Zn-air battery for remote sub-zero conditions, ideal for areas like the Himalayas where conventional batteries fail. This device combines an effective cathode catalyst and anti-freeze electrolyte. With rising energy demand, efficient storage systems are crucial. Traditional lithium-ion (Li-ion) batteries have limited energy density due to heavy cathode materials. Metal-air batteries, using metals like lithium, sodium, potassium, magnesium, aluminum, zinc, and iron,…

Deep-sea mining: balancing renewable energy gains with environmental risks

Extracting cobalt, nickel, rare earth elements, and other metals from the ocean depths could accelerate the world’s shift to renewable energy. These minerals, scarce on land and hazardous to mine, are abundant just above the ocean floor. However, the seabed’s unique ecosystems, filled with unexplored life forms, present significant challenges. The Metals Company, a Canadian firm, is exploring the mineral-rich Clarion-Clipperton Zone between Mexico and Hawaii. Their research has revealed not only strange life forms…

CEA recommends addition of 80 GW of coal-based capacity by 2031-32

The Central Electricity Authority (CEA) has recommended a coal and lignite-based installed capacity of 283 GW, up from the current 217.5 GW. Consequently, the Ministry of Power (MoP) is planning to establish an additional minimum of 80 GW of coal-based capacity by 2031-32. This expansion is expected to entail an expenditure of at least Rs. 6,672 billion by 2031-32. According to Intended Nationally Determined Contributions (INDCs), the country is committed to achieving approximately 50 per…

Steps taken to boost production capacity from 2014-15 to 2023-24

The Ministry of Power (MoP) detailed steps taken to increase the production capacity between 2014-15 to 2023-24 in a recent press release. Between 2014-15 and 2023-24, India increased its power production capacity significantly. The installed capacity rose from 248,554 MW in March 2014 to 446,190 MW in June 2024, with coal-based power growing from 139,663 MW to 210,969 MW, and renewable energy from 75,519 MW to 195,013 MW. The country added 195,181 ckm of transmission…

Decommissioning Coal-Based Plants in India

The proportion of installed capacity from coal/lignite has decreased from 55 per cent in 1947 to 50 per cent in 2024, but it still dominates, accounting for 50 per cent of installed capacity and 73 per cent of generation as of March 2024. Central Electricity Authority (CEA) projects coal/lignite will still comprise 32 per cent of installed capacity by 2030. Coal-based plant installations surged between 2007 and 2017, driven by high spot prices in power…

Hydropower: Achieving Global Renewable Energy Targets

At the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Dubai, global governments pledged to triple renewable generation capacity from 3.8 TW in 2022 to 11.2 TW by 2030. This increase in variable renewables poses grid security and flexibility challenges. Hydropower, among low-carbon options, is the most versatile and cost-effective solution for grid stability. Its key strengths are flexibility and resilience, complementing variable renewables with services ranging…
