What is the total amount of US Department of Energy funding committed to X-Energy’s Seadrift nuclear project, and how is it structured?

The US Department of Energy has committed a total of $2.115 billion in cost-share funding to X-Energy’s Seadrift nuclear project under the Advanced Reactor Demonstration Program (ARDP). This includes the newly announced $1 billion increment, which—like the original award—is subject to a 50-50 cost-share requirement between DOE and the project partners. The funding supports the design of X-Energy’s Xe-100 reactor, the design, construction, and licensing of its first fuel plant (TX-1), and the cost of the first full-scale deployment at Dow’s Seadrift, Texas facility.

When is Dow expecting the Seadrift nuclear facility to become operational, and what will it supply?

Dow aims to have the Seadrift nuclear facility online and supplying carbon emissions-free steam and electricity to its Seadrift, Texas facility by the early 2030s.
