5.22 - Sage Geosystems CEO Cindy Taff on Groundbreaking Geothermal Storage Technology That Makes Renewable Energy Cost-Effective

Geothermal systems are poised to make a huge impact on climate change, according to Tucker’s guest in this episode of Path to Zero podcast. Cindy Taff is the CEO of Sage Geosystems, a Houston-based geothermal and energy storage company.

Sage is building its first energy storage power plant this year and has successfully secured investments from companies traditionally involved in the oil and gas business. Taff and many on her team at Sage Geosystems bring years of experience with major oil and gas companies. Before joining Sage, Taff served as VP of Shell’s global Unconventional Wells operations and led a team of more than 350 Shell staff and 1200 contractors across five countries.
