Hyundai Motor has revealed a rendered image of its new concept hydrogen-powered fuel cell electric truck. The HDC-6 NEPTUNE concept will be debuted at the North American Commercial Vehicle Show in Atlanta. During the show, Hyundai will also debut a concept refrigerated trailer titled, HT Nitro ThermoTech. The company has a goal of zero carbon emissions and has named this new concept truck after the Roman god of seas, a massive source of hydrogen on Earth.
