Stellaria Targets 2035 Low-Carbon Energy Solution for Equinix Data Centers

According to a recent LinkedIn post from Stellaria, the company is working with Equinix on an energy solution for future data centers based on its Stellarium renewable-fuel reactor concept, with deployment targeted from 2035. The post indicates that Equinix has secured an initial reservation of energy capacity, positioning it as an early offtaker for this technology.

The LinkedIn post highlights several intended attributes of the reactor, including near-total on-site energy autonomy over a data center’s lifetime and the ability to support long-term, stable power purchase agreements for 24/7 electricity. It also suggests operational flexibility through a liquid-core design that can adjust output to match varying data center loads.

Stellaria’s post further points to safety and environmental claims, referencing design choices informed by six decades of nuclear operating experience and emphasizing a fully renewable on-site fuel cycle with significantly reduced long-lived high-level waste. If realized at scale, these features could appeal to hyperscale and colocation operators seeking firm, low-carbon power and may enhance Stellaria’s positioning in the emerging market for decarbonized, resilient data-center energy infrastructure.

For Equinix, early access to such a solution could support long-term energy cost visibility and carbon-reduction objectives, although the 2035 deployment horizon and technology execution risks suggest a long-dated impact on financials. The involvement of partners such as Schneider Electric, referenced in the post, indicates an ecosystem approach that could help de-risk integration but also underscores that regulatory, technical, and financing milestones remain key determinants of future commercial relevance for investors.
