April 2
By 2030, utility-scale solar installations could cover almost 2 million acres of land in the United States. Traditional solar development would monopolize this land for just one use: energy production. Low-impact solar development, on the other hand, might also improve soil health, retain water, nurture native species, produce food, and provide even lower-cost energy to local communities. The Innovative Site Preparation and Impact Reductions on the Environment (InSPIRE) project brings together researchers to better understand the benefits of—and barriers to—low-impact solar development.

August 14
A far-reaching vision for the future of the electric grid is emerging at NREL. In the past few years, this vision has grown from a theory on whiteboards to real-power experiments on lab hardware. It's called "Autonomous Energy Grids" (AEG), an effort to ensure the grid of the future can manage a growing base of intelligent energy devices, variable renewable energy, and advanced controls. The AEG effort envisions a self-driving power system—a very "aware" network of technologies and distributed controls that work together to efficiently match bi-directional energy supply to energy demand. This is a hard pivot from today’s system, in which centralized control is used to manage one-way electricity flows to consumers along power lines that spoke out from central generators.

12. Exploring Tomorrow’s Energy Solutions, Together

August 22
NREL’s 2019 Partner Forum brought together energy industry leaders across multiple sectors to discuss today’s energy challenges and explore tomorrow’s potential solutions. While their backgrounds were diverse, the entities represented at the third annual forum had one thing in common: They all face very real energy-related challenges in the years and decades ahead—challenges greater than any one company or organization can solve alone. The goal is to inform future laboratory research and cultivate the partnerships that will develop and commercialize new technologies to advance the U.S. energy market.

13. NREL Marks Partner Forum with Dedication of Bioreactor

August 22
Installed outside NREL’s Energy Systems Integration Facility, a new hydrogen-to-methane bioreactor is the first of its kind in the United States. It uses a selectively evolved microorganism that feeds on renewable hydrogen produced at NREL and a diet of carbon dioxide to produce pipeline-quality methane. The microorganism, known as Methanothermobacter thermautotrophicus, is a thermophile, meaning it thrives in hot environments. The temperature inside the bioreactor is about 150°F.

14. NREL Appoints Three Scientists as Senior Research Fellows

October 23
Many people looking for a new house have considered metrics like “walk score” or “transit score,” and even “bike score.” But what most don’t know is that these metrics, while useful, aren’t designed to capture the whole story of an area’s transportation options. The Mobility Energy Productivity (MEP) metric comprehensively quantifies the efficiency of transportation systems while taking time, affordability, and energy use into consideration. The MEP metric measures the existing and potential impact of all mobility options in a given area. And it does so in a way that assesses both existing and future mobility options.

19. R&D 100 Awards Honor Two NREL Innovations
