Which energy option can be stored and transported to cover periods when renewables are not generating power?

• A. Hydrogen
• B. Coal
• C. Oil
• D. Natural gas

Answer: (A)

The concept here is storing and delivering energy to bridge gaps when renewables aren’t producing power. Hydrogen fits best because it can be produced from excess renewable electricity (green hydrogen), stored for long periods, and transported to where it’s needed. It can be kept as a gas or liquid, stored in tanks or underground caverns, and shipped or piped to power plants or other users. When demand rises or wind and sun aren’t enough, hydrogen can be converted back to electricity in fuel cells or turbines, providing a flexible, low-emission backup. Fossil fuels can be stored and moved as well, but they’re used by burning the fuel, and they don’t offer the same clean, flexible storage role that hydrogen provides for supporting intermittent renewables.
