Electric cargo ships Voltic is reducing greenhouse gas emissions in the shipping industry by retrofitting diesel ships to be electric. Electric cargo ships have the potential to eliminate 2.2% of global CO2 production, while simultaneously cutting shipping costs by 50-75% depending on route. We are making a boat that is both greener and cheaper. We've closed our first customer, who will pay us to ship containers for them. In addition to YC, we've also received funding from the Department of Energy and support from professors in MIT's Ocean Engineering Department.
