Since 2019, the American Chemical Society (ACS) has published an annual series, titled "Women Scientists at the Forefront of Energy Research," to celebrate the accomplishments of women in the energy science field.

Over the years, ACS has asked over 80 women—including eight National Renewable Energy Laboratory (NREL) scientists—to share their personal stories of what inspires and motivates them, what has led to their success, and what wisdom they would like to share with the next generation of researchers. The latest edition of the series was published last month.

"It is great to see our NREL energy scientists featured by ACS and sharing their passions, motivations, and wisdom," said Nancy Haegel, center director of NREL's Materials Science Center. "There is a common theme in their advice about being open—open to new ideas, people, and opportunities, and to risk, particularly the risk of letting your creativity and passions take you where they lead."

"I'm pleased, though not surprised, to see so many NREL staff featured in the series," Nancy continued. "I think that reflects the visibility of their work and the fact NREL has a mission that fosters creativity and impact.  We couldn't have better ambassadors."

Excerpts of their contributions are included below.

Annie Greenaway, Materials Chemistry Researcher

Annie Greenaway joined NREL full time in 2018 as a director's postdoctoral research fellow, after having completed two summer internships at NREL as an undergraduate. She is now a staff scientist in the Materials Physics group, where she works on solar fuels generation and the discovery and development of novel semiconductors.

In her contribution to the ACS Energy series, Annie recalls that when she first began to consider a career as a scientist, she struggled to find a way to combine science with her passion for public service. "I was not sure how to make a difference in people's lives as a scientist," she said.

That changed when Annie joined NREL as a summer intern and discovered the vast array of possibilities for making an impact through science. Her message to young scientists is an encouraging one. "If there is a scientific problem that you feel needs to be answered, do not be afraid to dig into it—we need all the help we can get finding new sources of energy and methods for storage and improving energy efficiency."

Laura Schelhas joined NREL in 2020 as the group manager for hybrid and nanoscale chemistry. Her research focuses on materials characterization and photovoltaic reliability. Prior to joining the laboratory, she held a position in the Applied Energy Division at SLAC National Accelerator Laboratory.

In her contribution, Laura reflects on a pivotal shift in her approach to her research. "At some point I realized if I was understanding how to make things, it was also important to understand how they break," she said. "My research allows me to ask not only 'why do things break?' but also 'what's the best way to break them?' These concepts and themes have been what's driven me to where I am today."

She also offers a reflection on what it means to pursue a successful career in science. "Some days, I wish I had a great epic story of how I ended up here at NREL researching renewable energy, but my path to this point has had one clear theme: 'Does my work make me smile?'" Laura said.
