About Danielle Lemmon

Dr. Lemmon is a technical expert with a PhD in climate science and experience spanning academic research, the U.S. Department of Energy and private-sector consulting. This multidisciplinary perspective has made Dr. Lemmon a trusted source for both clients and media partners seeking insights into energy, climate and policy challenges. Her work has been featured and quoted in outlets like The New York Times, The Washington Post, The Hill, POLITICO and Forbes, and she has co-authored publications in leading scientific journals Nature and Science. She has a strong social media presence on Instagram, TikTok and LinkedIn and has made more than 10 radio and podcast appearances. She is known for her ability to simplify complex information and speak candidly on sensitive topics.

Dr. Lemmon has served as a climate and energy consultant at Ramboll since 2024. She develops business strategies for high-growth sectors such as energy, critical minerals and data center infrastructure. She supports clients as they navigate policy changes, funding programs and shifting energy markets. Her responsibilities include shaping government engagement strategies, securing funding pathways and positioning projects for success within complex regulatory frameworks.

In addition, Dr. Lemmon supports business development and client engagement. She provides in-person support at government meetings and industry events and represents Ramboll across Washington, D.C.

Before joining Ramboll, Dr. Lemmon served as a climate technology portfolio advisor for the U.S. Department of Energy's Office of Clean Energy Demonstrations from 2022 to 2024. She helped build the office during its early stages and supported federal investments in hydrogen, industrial decarbonization, energy storage and carbon capture. One of her most meaningful achievements was developing a portfolio strategy for long-duration energy storage. She combined technology data from national laboratories with demographic data from communities to identify areas that most frequently experience power outages – helping direct federal investments to place grid resilience technologies in communities that needed them the most.

From 2020 to 2022, Dr. Lemmon served as a postdoctoral research fellow at the IBS Center for Climate Physics in South Korea. There, she studied how long-term climate change influenced human evolution and migration over the past 2 million years. Earlier, she served as a graduate teacher program lead at the University of Colorado Boulder and earned a National Science Foundation Graduate Research Fellowship in climate science. She also taught laboratory courses, teaching over 750 students during her time as a college teacher. Prior to graduate school, she also worked as a nuclear fusion research assistant at Woodruff Scientific, programming code and working with the manufacturing team to develop the technology readiness of nuclear fusion.

Dr. Lemmon earned a Bachelor of Science in physics with a minor in atmospheric sciences from the University of Washington and a Doctor of Philosophy in atmospheric and oceanic sciences from the University of Colorado-Boulder. Her doctoral research examined how climate change affects El Niño Southern Oscillation, and the impacts on global food and water security. She holds graduate certificates in college teaching and in science and technology policy.

Alongside her consulting work, Dr. Lemmon closely follows trends shaping the energy sector. These include the effects of federal regulation and differing state policies, the growing power demand from artificial intelligence and data centers, and the impact of geopolitical conflict on energy markets. She tracks how rising material costs affect investor confidence and long-term infrastructure planning.

Making an Impact

Dr. Lemmon leads by building trust and encouraging collaboration. She values openness, feedback and humility. She believes strong teams form when people feel heard and supported, and she works to create environments where shared purpose guides progress.
