Is there an Alternative ? “With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom, so that the first car driven by a child born today could be powered by hydrogen, and pollutionfree. ” President George W. Bush 2003 State of the Union Address 9/17/2020 5

Problem Statement n n Ø Ø Ø Design a renewable energy based hydrogen generation station. Client Requirements: Use existing renewable energy sources to produce hydrogen gas.
