20-16 Consider the situation where all 250,000,000 gasoline-powered vehicles in the United States, each of which is driven an average of 20,000 km per year and requires an average of 0.55 MJ/km from the batteries, would be replaced with PEM-fuel cell vehicles that use hydrogen produced by electrolysis using electricity generated by 1-GWe nuclear power plants (operating at a 70% capacity factor). How many new nuclear power plants would need to be constructed to accommodate this increase in electricity demand?
An engineer was tasked with evaluating a heat and power generation unit for an aluminium smelting plant. The management intends to expand the production facilities to meet growing demand for aluminium. The plan involves increasing the energy intensive smelting line from the present single line to three lines by end of 2022. To support the expansion plan, the company plans to install a self-sufficient power generation unit. Details of the energy requirement and the proposed power generation unit is given the following Table. Item Power requirement per smelting processing line 0.6 MW Proposed power generation unit: Supplier • System Description Mitsubishi Heavy Industries Ltd Steam power plant (Carnot heat engines principles) 35% • Overall thermal efficiency Prepare a mini technical power evaluation report for the above project.
