Battery energy storage system

 

Battery energy storage system

Context: The Indian government has approved viability gap funding (VGF) to cover up to 40% of the total capital cost for the establishment of a 4,000 MWh battery energy storage system (BESS) in the country.

What It Is?

  A battery energy storage system is a type of energy storage system that uses batteries to store and distribute energy as electricity.

  BESSs are often used to enable energy from renewable sources, like solar and wind, to be stored and released.

Components

  Batteries (lithium-ion, lead-acid, etc.).

  Inverters for converting DC to AC power.

  BMS (Battery Management System) for monitoring and managing battery health and performance.

Applications

  Grid stabilization and frequency regulation.

  Energy shifting to optimize energy consumption.

  Backup power during outages.

  Integration of renewable energy sources.

Benefits

  Smoothing out intermittent renewable energy generation

  Reducing peak demand and associated costs

  Enhancing grid reliability

  Supporting renewable energy adoption.

Types

  Residential BESS for homes

  Commercial BESS for businesses

  Utility-scale BESS for large-scale energy storage.

Environmental Impact

  BESS can reduce greenhouse gas emissions by improving energy efficiency and integrating renewable energy sources.

Challenges

  High initial costs

  Battery degradation over time

  Recycling and disposal of batteries

  Regulatory and grid integration issues.

Quantum Nonlocality

  Quantum Nonlocality: §   While classical physics assumes locality, the principle of nonlocality is a feature of many interpretations of quantum mechanics. §   Nonlocality describes the apparent ability of objects to instantaneously know about each other’s state, even when separated by large distances (potentially even billions of light years), almost as if the universe at large instantaneously arranges its particles in anticipation of future events. §   This is in direct contravention of the "principle of locality" (or what Einstein called the "principle of local action"), the idea that distant objects cannot have direct influence on one another, and that an object is directly influenced only by its immediate surroundings, an idea on which almost all of physics is predicated. §   Non locality occurs due to the phenomenon of entanglement, whereby particles that interact with each other become permanently correlated, or dependent on each other’s states a...
