Z Ships International proposes a solution to reduce ship emissions and fuel costs to zero through the use of renewable energy technologies including wave energy conversion, solar panels, wind turbines, and magnetic generators. Their prototype retrofit system could save fishing vessels 40-50% in fuel costs and reduce emissions, with a return on investment period of 6 years. A 6-year business plan forecasts positive cash flows and a net present value of $56 million Canadian dollars from retrofitting and producing new ships.
