51�Թ��� Professor Alexis Templeton will discuss hydrogen as a clean energy source and as an energy source for life in the Earth during her Nov. 20 Distinguished Research Lecture

As nations around the world work to decarbonize and bolster their energy security, many of them are turning to hydrogen gas as an alternative energy source.

At the 51�Թ���,��Alexis Templeton, a professor of��geological sciences, is developing projects around the world with academic, government and industry partners to harvest naturally occurring, low-carbon��hydrogen from beneath the Earth’s surface.

Alexis Templeton, a 51�Թ��� professor of geological sciences, studies how microbial life interacts with geology in extreme environments.��

“Hydrogen is one of the most powerful and versatile energy sources on Earth. It has long been used to power microbial life activity in dark, rocky parts of our planet where other forms of energy are scarce, and excitingly now humans are trying to harness this globally abundant energy source as well,” Templeton says.

Templeton’s research into the geochemistry of subsurface rocks—how they interact with water to produce hydrogen—offers the promise of clean energy innovation in the not-too-distant future. She will share details about that aspect of her research—as well as how hydrogen sustains microbial life in Earth’s deep subsurface environments—in the��126th Distinguished Research Lecture, “Hydrogen: Integrating the Searches for New Energy Sources and Novel Life Activity Within the Earth,” at 4 p.m. Thursday, Nov. 20, at the Chancellor’s Hall and Auditorium, Center for Academic Success and Engagement (CASE). A question-and-answer session and reception will follow the lecture.

“I’m deeply honored to be selected to deliver a Distinguished Research Lecture on the 51�Թ��� campus. I truly appreciate the support of my colleagues here at the University of Colorado and in the international geochemistry and geobiology community who supported this nomination and the work that will be shared,” Templeton says.

About Alexis Templeton

Templeton is a professor in the��Department of Geological Sciences and the��. Her��research spans the globe—from volcanoes in the Pacific to cold springs in the High Arctic to the mountains and deserts of the Arabian Peninsula—but it all centers on one goal: understanding how microbial life interacts with geology in extreme environments.

With funding from NASA, the U.S. Department of Energy and the Grantham, Packard and Simons Foundations, she has led several large multidisciplinary projects to investigate the subsurface biosphere on Earth and the potential for similar life forms to exist elsewhere in the solar system.

At 51�Թ���, Templeton��trains students and postdoctoral scholars in the realms of geochemistry, geomicrobiology and astrobiology and co-directs the Raman Chemical Imaging laboratory, a CU-51�Թ��� Core Facility.��She is an active member of the geobiology program, and she teaches several courses in geochemistry that blend classroom learning with field experiences in the mountains of Colorado.

Templeton received her bachelor’s and master’s degrees from Dartmouth College, her PhD from Stanford University and her postdoctoral training from Scripps Institution of Oceanography.

About the distinguished research lectureship

The��Distinguished Research Lectureship��is one the highest honors bestowed by CU��51�Թ��� faculty upon a colleague. Awarded annually by the Research and Innovation Office, it recognizes tenured faculty members, research professors (associate or full) or adjunct professors who have been with 51�Թ��� for at least five years for a distinguished body of academic or creative work, as well as contributions to the educational and service missions. Each recipient gives��a lecture in the fall or spring and receives a $2,000 honorarium.
