 The Brazilian energy grid is considered one of the cleanest in the world due to its high percentage of renewable energy sources. To evaluate the feasibility of producing hydrogen using alkaline electrolysis powered by the Brazilian energy grid, a project was analyzed for a 20-year lifetime. The project's capacity, production volume, hydrogen sale price, and marginal revenue rate were varied. At a hydrogen sale price of, per kilogram, all project sizes are economically viable. Under these conditions, the project has a payback period of less than four years, an internal rate of return of over 31%, a break even point between 56% to 68% of the production volume, and a return on investment of over 400%. Additionally, the sensitivity analysis revealed that the best economic condition was achieved when the project produced 35.56 kilograms of hydrogen per hour, generating a net present value of 0.4 million. Furthermore, the cost of hydrogen ranged from 0.26-0.64 per kilogram, while the levelized cost of hydrogen was estimated to be 7.
