Parallax Raises $117M for AI Data Center Power

The insatiable demand for artificial intelligence computing power is encountering a critical bottleneck: electricity. As data centers scale rapidly, the ability to secure sufficient grid capacity has become a significant constraint, with projections indicating a potential shortfall of over 65 gigawatts by the end of the decade. Addressing this urgent need, Parallax, a startup focused on innovative gas turbine technology, has emerged from stealth having secured $117 million in funding.

The company's substantial backing includes a $42 million seed round co-led by Eclipse and Lux Capital, with participation from Founders Fund and Valor. Following this, Greylock Partners and General Catalyst spearheaded a $75 million Series A investment, with Diffusion also contributing. This capital infusion is earmarked for the development and deployment of Parallax's novel energy generation systems.

Parallax is engineering a new generation of compact, approximately 10-megawatt gas turbines specifically designed for data center applications. Unlike traditional manufacturers who rely on specialized, supply-constrained materials like single-crystal blades and rhenium superalloys, Parallax is adopting a different approach. By optimizing for cooler operating temperatures, the company aims to eliminate reliance on these chokepoints and simplify manufacturing through advanced techniques like 3D printing, drastically reducing the number of components required.

Founder Carl Schoeller, a Stanford-trained mechanical engineer with prior experience developing complex components for companies like Tesla and Apple, stated the company's focus is solely on the unique demands of data centers, free from the constraints of utility or aerospace design. Parallax plans to have a prototype operational by year-end, with testing slated for next year and initial customer deliveries targeted for 2028. This timeline positions them to address the immediate power gap facing the AI sector.

The challenge of powering AI is spurring a wave of innovation across the energy infrastructure sector. Beyond Parallax's ground-up turbine design, other companies are exploring various strategies. These include repurposing existing engine technology, such as GE Vernova's aeroderivative turbines and ProEnergy's use of retired jet engine cores. Major players like Caterpillar, Cummins, and Generac are also redirecting their generator businesses towards AI data centers, with Generac securing a significant deal with Amazon valued up to $8 billion.

Furthermore, the market is seeing a rise in on-site power plant development, bypassing traditional grid infrastructure. VoltaGrid is deploying natural gas microgrids for Oracle, while Joulent is partnering with Chevron on a substantial natural gas plant for Microsoft. The long-term energy horizon also includes significant investments in small modular nuclear reactors (SMRs) by tech giants like Google, Amazon, and Meta, though commercial deployment is not anticipated before 2030, potentially lagging behind the immediate needs Parallax aims to meet.
