Key Takeaways
- Solaris Energy Infrastructure (NYSE: SEI) has made an equity investment in Deployable Energy and agreed to help commercialize the startup’s deployable microreactor technology.
- The companies announced the agreement on August 10, 2026; Houston-based Deployable Energy develops transportable small modular reactor (SMR) systems.
- The technology targets defense, industrial, and digital infrastructure customers that need resilient power delivered on short timelines.
- Solaris pointed to Deployable Energy’s speed to first criticality and a design approach built to avoid supply chain constraints.
- The collaboration pairs Deployable Energy’s reactor engineering with Solaris’ experience operating distributed power infrastructure.
Solaris Backs Deployable Energy’s Reactor Program
Deployable Energy said on August 10, 2026 that Solaris Energy Infrastructure, Inc. (NYSE: SEI) has taken an equity stake in the company and joined as a commercialization partner for its deployable microreactor technology. The Houston company designs transportable nuclear power systems for critical energy infrastructure, and the agreement gives it both capital and a path toward the market.
The startup’s reactors are built to be moved and set up quickly, a format the company is aiming at defense, industrial, and digital infrastructure users. Solaris, which supplies power equipment for demanding sites, will work with the startup to bring those systems into commercial service.
Inside the Deployable Energy Collaboration
The arrangement combines Deployable Energy’s engineering with Solaris’ record of deploying and maintaining distributed energy infrastructure for mission-critical applications.
“We’re excited to welcome Solaris as both an investor and strategic collaborator. Solaris has established itself as a leader in delivering reliable power infrastructure for demanding applications,” said Bobby Gallagher, CEO and Co-Founder of Deployable Energy.
Why Solaris Sees a Fit
Solaris tied its decision to the pace of the startup’s technical progress and its plan for avoiding the supply bottlenecks that have slowed other nuclear developers.
“The speed they’ve shown getting to first criticality, their differentiated design and approach to avoiding supply chain constraints, gives us confidence that the Deployable Energy team can turn next-generation nuclear products into reality in the relatively near term,” said Bill Zartler, Founder and Co-CEO of Solaris Energy Infrastructure.
Neither company disclosed the size of the investment. Deployable Energy has said its systems are designed for rapid transport and setup, which it presents as a way to add firm power where grid connections are limited or slow to build.
