Pumped hydro key to meeting storage demand
Pumped hydro energy storage can be readily scaled to any required storage capacity at a known and affordable cost.
Lithium discovery big win for India, but concerns remain over mining and refining
India has struck gold by discovering 5.9 million tonnes of lithium resources in Jammu & Kashmir. The nation now needs to work towards building the capacity to extract lithium in a sustainable and eco-friendly way.
India needs over $4 billion to create 50 GWh of lithium battery capacity under PLI Scheme: CEEW
A new study by CEEW deconstructs the lithium-ion battery cell manufacturing process, calculates the material and finance requirements, and offers a blueprint for the domestic strategy.
Renewable energy auctions not in tandem with government targets
India tendered only about 28 GW of variable renewable energy capacity in 2022, as against 40 GW in 2019. The nation needs to add 30-35 GW of new VRE capacity annually to reach its climate targets by 2030 and that requires more than 35 GW of annual tendering.
Replacing MPPT with direct PV-battery coupling
Researchers in Germany have assessed direct coupling and integration between PV and batteries at the scale of a single PV module. They say their solution could be cheaper and provide superior performance than maximum power point tracking (MPPT) in optimizing PV system performance.
Guidelines for pumped storage projects in India
The draft guidelines released by the power ministry include concessional climate finance and utilization of exhausted coal mines as sites for pumped storage projects.
Australian scientists unveil method to produce hydrogen straight from ocean
University of Adelaide researchers and their international partners have successfully used seawater with no pre-treatment to produce green hydrogen. They did this by introducing an acid layer over the catalysts in situ.
Budget 2023-24 reaffirms government’s focus on domestic solar and battery manufacturing, green hydrogen
The budget signifies the government’s intent to drive domestic manufacturing of lithium battery cells as it waives customs duty on the import of machinery required for manufacturing these cells. It also continues with nil customs duty on critical inputs for solar manufacturing. The budget also aims to support large-scale battery storage projects through viability gap funding.
Retired coal sites to host multi-day iron-air batteries
Form Energy will install two 10 MW / 1,000 MWh batteries on the sites of Xcel Energy’s former coal-fired plants.
THDC, RRECL form JV to build 10 GW of renewable energy projects in Rajasthan
State-run hydropower producer THDC has formed a 74:26 joint venture with Rajasthan Renewable Energy Corp. Ltd to develop 10 GW of renewable energy projects in Rajasthan. The JV partners also plan floating solar and pumped hydro storage projects in the state.
