Cars, Concrete, and Changes to the Grid

Transforming Energy: The NREL Podcast

In this episode, our hosts discuss:

• Carbon-Negative Concrete – Learn about the BUILD'EM project, which aims to replace traditional cement with a low-carbon alternative made from lignin and other innovative materials. This new concrete not only reduces emissions but also promises to be cost-competitive and environmentally friendly. Discover how these new pavers could significantly lower the carbon footprint of concrete and contribute to a more sustainable built environment.
• EV Charging Infrastructure – With electric vehicle sales surging, NREL researchers are focused on expanding the national charging network to ensure convenient, reliable access for all drivers. We’ll discuss the tools and models, like the EVI-X Modeling Suite and TEMPO, that are guiding the deployment of charging stations and the importance of equitable infrastructure.

Plus, understand the need for a modernized grid to accommodate the growing use of renewable energy sources. We’re developing medium-voltage converters that could replace traditional transformers. These new devices aim to enhance grid flexibility, reduce costs, and support the integration of solar and wind energy into the power system.
