The transition to clean energy is becoming more visible with the increasing adoption of electric vehicles (EVs). In the United States, sales of light-duty EVs have significantly risen, highlighting the need for a national network of reliable and affordable charging stations to support long-term buy-in from drivers. Publicly accessible charging stations along highways and near homes, as well as private charging ports at residential properties and workplaces, are essential to encourage consumers to switch to EVs as their primary mode of transportation.
Researchers at the National Renewable Energy Laboratory (NREL) are developing innovative tools and conducting research to study zero-emission vehicles and their integration into the energy system. The laboratory’s EVI-X Modeling Suite and TEMPO model are instrumental in guiding the deployment of charging infrastructure and exploring pathways for achieving long-term climate goals. Factors such as interest in reducing greenhouse gas emissions, EV performance, and lower operating costs are driving consumers towards embracing EVs, particularly in states with regulations and incentives supporting zero-emission vehicles.
While EV adoption varies across different regions, there is a growing need for more reliable and accessible charging stations to meet the increasing demand. Collaboration between NREL researchers and the Joint Office of Energy and Transportation aims to improve charging station reliability and availability to instill confidence in EV owners. Efforts are underway to address infrastructure challenges, including the slow deployment of charging stations, especially in rural areas that often require longer driving distances and face additional challenges in electrifying transportation.
To accelerate the deployment of charging stations, NREL researchers have developed tools such as EVI-LOCATE to estimate the cost of installing charging stations at specific locations. Addressing soft costs beyond hardware and installation expenses, such as permitting delays and coordination with utilities, is crucial in streamlining the process. By focusing on equity in EV infrastructure deployment, researchers are aiming to ensure that charging stations are accessible to all communities, including low-income and rural areas that may be currently underserved.
Ultimately, the goal is to make EV charging seamless and convenient for drivers, regardless of their living situation or location. By addressing infrastructure challenges, increasing the availability of charging stations, and promoting the benefits of EVs, NREL and other research institutions are paving the way for a cleaner and more sustainable transportation future. Through ongoing research and collaboration, the transition to electric vehicles is becoming more feasible and accessible for a broader range of consumers.
