Hydroelectric Power: — Water potential energy. High efficiency 80-90%.
Large Hydro: — >25 MW, now classified as renewable. Tehri Dam (India).
Small Hydro: — <25 MW, run-of-the-river.
Pumped Storage Hydro (PSH): — Energy storage, grid balancing. High efficiency 70-85%.
Geothermal Energy: — Earth's internal heat. Puga Valley (Ladakh) potential.
Biomass: — Organic matter for heat/electricity/biofuels. Carbon-neutral if sustainable.
National Policy on Biofuels 2018: — Promotes ethanol blending.
Ethanol Blending Target: — 20% by 2025 (E20).
SATAT Initiative: — For Compressed Biogas (CBG).
Nuclear Fission: — Splitting atoms for energy. Zero operational emissions.
India's 3-Stage Programme: — Aims to use Thorium-232 for long-term fuel security.
Kudankulam NPP: — India's largest nuclear power plant.
Green Hydrogen: — Electrolysis of water using renewable electricity. Zero emissions.
National Green Hydrogen Mission (2023): — India aims for 5 MMTPA by 2030.
Fuel Cells: — Convert hydrogen to electricity, water as byproduct.
Ocean Energy: — Tidal, Wave, OTEC. High potential but nascent, high cost.
Gulf of Kutch: — High tidal energy potential.
Energy Storage: — Batteries (Li-ion), PSH, CAES, TES. Crucial for RE integration.
Li-ion Batteries: — Dominant, 85-95% round-trip efficiency.
Smart Grids: — Digital tech for optimized electricity flow, RE integration, two-way communication.
Clean Energy Trilemma: — Balancing Affordability, Reliability, Sustainability.
India's NDCs: — 50% non-fossil capacity by 2030, 45% emissions intensity reduction by 2030.
PLI Scheme: — For Advanced Chemistry Cell (ACC) battery manufacturing.
RPO: — Renewable Purchase Obligations for DISCOMs.
Grid Parity: — RE cost equals conventional grid cost.
Capacity Factor: — Actual output / Max possible output.
LCOE: — Lifetime cost of energy generation.
Carbon Capture, Utilization, and Storage (CCUS): — For reducing emissions from fossil fuels.
Vyyuha SHINE Mnemonic: — Solar, Hydro, Integration (storage/grid), Nuclear, Emerging (hydrogen/ocean).
