Long-Term Supply Agreement between SGL Carbon and X-energy
Published : May 15, 2026
X-energy Reactor Company, LLC and SGL Carbon LLC have signed a 10-year framework agreement to provide graphite for the deployment of X-energy’s Xe-100 small modular reactor (“SMR”).
SGL has been awarded an initial three-year contract valued at around 100 mUSD to supply medium grain-graphite supply for X-energy’s first commercial project, a proposed four-unit Xe-100 plant in partnership with Dow, Inc. in Seadrift, Texas. Graphite production on graphite reactor components has started, and SGL will supply components within three years for a total value of around 100 mUSD.
X-energy and SGL have also signed an agreement to reserve capacity and develop production readiness for the Cascade Advanced Energy Facility with Energy Northwest in Washington state. Cascade is a planned 12-unit Xe-100 plant, and the first of several proposed Amazon and X-energy projects targeting at least five gigawatts of new nuclear energy by 2039. Graphite production is expected to begin in the second half of 2026.
