As electricity demand surges—driven in part by the growth of data centers—this year’s most innovative companies in energy are finding new ways to meet that demand without driving up power bills or emissions. Others are tackling different pieces of the energy transition, from materials to electric mobility.

For using AI to discover hidden geothermal power
By combining advanced AI with modern drilling techniques and computational geoscience, Zanskar identifies hidden or underutilized sites for geothermal power plants that conventional exploration methods have failed to detect. In December 2025, the company announced that it had discovered a site in Nevada capable of supporting a new geothermal power plant that would deliver clean, always-on energy to the grid. The site had no prior history of geothermal exploration and showed no surface-level indicators of geothermal potential, making it the first “blind” geothermal system in the United States to be discovered with clear commercial potential in more than 30 years.

For making lithium production faster and greener
Lilac Solutions has developed a faster, more sustainable method for extracting lithium—the critical raw material used in batteries that power electric vehicles and the electric grid—which could soon face a supply shortage. The company, which has raised $318 million to date, designed tiny, reusable ceramic beads that capture lithium from brine and then safely return the brine to the environment without depleting water levels. In a seven-month-long pilot at Utah’s Great Salt Lake in 2025, Lilac validated its technology, showing that it can recover lithium efficiently while protecting the lake’s ecosystem.
