Opening
Recently, countries have shifted focus on energy storage technology for providing round the clock availability of energy. They can be instrumental in providing efficient energy supply.
(A) Battery Energy Storage system (BESS)
Body · points and prose
)
- Decarbonising world via realisation of Net-zero (eg: India by 2070)
- Renewable energy to be explored in off-shore sectors (eg: floating solar plant)
They can be instrumental in providing efficient energy supply.
(A) Battery Energy Storage system (BESS) → This involves utilising surplus energy to charge and store as chemical energy.

| 1) Provides supply when source is gone | 1) Provides DC current, thus lowered efficiency |
| 2) Affordability | 2) Issue in integrating with main supply |
(B) Pumped hydro-storage system This is used to pump water to a higher level and then utilise the flow during decreased natural flow of water.

|---|---|
| 1) Provides stability to power supply | 1) Huge initial cost of installation |
| 2) Enhances accessibility to renewable energy | 2) Research & innovation required for better integration |
The renewable energy sector now constitute about 50% of India's installed power capacity. Energy storage can provide secure, scalable and sustainable power supply.
