Willkie recently represented energy storage business Caliche Development Partners in its acquisition by Sixth Street, a leading global investment firm, announced on August 20.

Caliche is a Houston-based energy company focused on the underground storage of natural gas, industrial gases like hydrogen and helium, and carbon sequestration.

Sixth Street's investment includes the company's Golden Triangle Storage (GTS) facilities and carbon sequestration development project in Beaumont, TX, and its Central Valley Gas Storage facilities in Princeton, CA. The investment provides Caliche with additional resources to pursue new opportunities and to expand the GTS complex.

Following the close of the transaction, Caliche's leadership will continue to oversee day-to-day operations and will remain investors in the company. Sixth Street's investment is subject to certain regulatory approvals.

The Willkie deal team was led by partner Archie Fallon and included partners Kris Agarwal, Ryan Giggs, counsel Emerson Girardeau, and associate Zoe Sellman.
