One of the main problems that electric vehicles (EVs) face is that lack of support infrastructure. You wouldn’t want to drive interstate only to find that there isn’t a charging station for your EV in the area. Honda’s vision for a solar-powered home-based hydrogen production station is an effort to ease the transition from fossil to alternative fuels. The company has since revealed plans to trial a solar-powered public EV charging station. The program will be tested over in Japan and the ultimate goal of it is to achieve what Honda calls Total Energy Management, which is a system that supplies households and communities with energy for personal use, while supporting a comfortable low-carbon lifestyle.
