Clean Energy Infrastructure MCQ — 84 Practice Questions with Answers

Q1. Consider the following statements: 1. Lithium-ion batteries store and release energy through the movement of lithium ions between electrodes. 2. Megawatt-hour is a unit of battery voltage, not of stored energy. 3. A battery with a 60 MW power rating can provide at most 60 MW instantaneously, though the duration depends on its energy capacity. Which of the statements given above are correct?

Q2. Consider the following statements: 1. Green hydrogen can be produced by using electricity to split water into hydrogen and oxygen in an electrolyzer. 2. An electrolyzer in a green-hydrogen plant is a wind turbine used to convert wind energy into mechanical energy. 3. Renewable electricity that might otherwise be curtailed can be used to produce hydrogen through electrolysis. Which of the statements given above are correct?

Q3. Consider the following statements: 1. In the grid-connected rooftop solar programme, central financial assistance or subsidy is provided to residential electricity consumers under Component-A. 2. The same rooftop solar programme provides incentives to distribution companies under Component-B. 3. Under the national-portal mechanism, applicable financial assistance is transferred directly to the empanelled vendor before installation and verification. 4. A residential consumer can apply either through the National Portal for Rooftop Solar or through the State distribution-company portal. Which of the statements given above are correct?

Q4. Consider the following statements about green corridors and renewable evacuation: 1. Scattered solar projects can require separate transmission lines to the nearest substation. 2. Green Energy Corridor planning emerged because power evacuation and nearby transmission infrastructure at potential renewable sites were found inadequate. 3. Green Energy Corridor infrastructure is meant only for rooftop solar systems, not large-scale solar and wind plants. 4. State transmission plans under the Green Energy Corridor process were submitted to the Central Electricity Authority for appraisal. Which of the statements given above are correct?

Q5. Consider the following statements about green hydrogen: 1. Green hydrogen can be produced through electrolysis using electricity from renewable sources such as solar, wind or hydropower. 2. Electrolysis splits water into hydrogen and oxygen. 3. MNRE describes coal gasification as the only clean and sustainable method for green hydrogen production. 4. Biomass gasification is also mentioned as a method of producing green hydrogen. Which of the statements given above are correct?
