The shift in the energy industry has begun to gain momentum in the transportation sector, too. When vehicles are fueled by electricity from renewable sources, e-mobility is more than just the clean and sustainable mobility solution of the future. Electric vehicles are becoming increasingly appealing for car fleet operators, companies and private individuals. The coming years will see hundreds of thousands of new electric vehicles on the roads and millions more charging stations installed, and half of these will be financed by private investors alone. Electric vehicles could make up around a third of all newly registered vehicles worldwide as soon as 2030.
When it comes to e-mobility, the combination with PV is of particular interest because private households and companies alike are already increasingly producing, consuming and storing power themselves as prosumers. There is a growing trend for charging electric vehicles using solar power generated on the owner’s own roof and, as a next step, integrating these vehicles’ batteries into the grid to help with stability and load shifting. Alternatively, prosumers can also share power with others over certain platforms, market it via aggregators or feed it back into the public grid. Consequently, the previously separate sectors of electricity, heating, cooling and mobility are becoming more and more interconnected, for example through heat pumps, cogeneration systems or e-mobility. Sector coupling is helping to enable rational, climate-friendly utilization of excess wind and solar power.
