An electrolyser can be charged with an efficiency of 35 %. It is charged from a wind mill at 40 €/MWh. A Li-Ion battery can be charged with an efficiency of 92%. A nuclear plant is charging the batteries at a cost of 150 €/MWh. Which system is cheaper to charge ? a. Electrolyser b. Li-Ion battery

Texts: Question 1: A wind energy project that will cost $3,000,000 to build and will generate an average of 500,000 kWh per year for 20 years. The project has an estimated capacity factor of 40%, which means it will generate power 40% of the time. The estimated O&M costs for the project are $50,000 per year, and the cost of capital is 6%. A natural gas generator that will cost $500,000 to purchase and will generate an average of 100,000 kWh per year for 10 years. The fuel cost for the generator is estimated to be $0.10 per kWh, and the maintenance costs are estimated to be $5,000 per year. The cost of capital is 6%. A- If the above projects are proposed, which of them should be selected based on LCOE ($/kWh). B- If the gas generator electricity has a lower LCOE, how much carbon tax ($/Ton of CO2) needs to be added so that the renewable energy project is more feasible (lower LCOE)? Natural gas produces 0.185 kg CO2 per kWh.
