Should tech companies be required to use greener power sources for their data centers?
American Supercritical emerged from stealth on September 23, 2026, with $8 million in funding to develop supercritical carbon dioxide technology for data centers. The firm intends to retrofit gas turbines to capture heat that would otherwise be lost.
Why it matters
Data centers face immense pressure to improve power efficiency as artificial intelligence operations drive energy demand higher. This technology seeks to address the massive emissions profile of current power plants, which can reach 33 million tons of greenhouse gases annually.
The firm targets a 50 percent increase in turbine efficiency, which currently sits at 35 percent for simple-cycle turbines versus 60 to 65 percent for combined-cycle plants. The system uses a closed-loop, supercritical carbon dioxide process to absorb exhaust heat and generate electricity without steam.
The players
American Supercritical
A startup focused on energy-efficient data center power systems using supercritical carbon dioxide.
The details
The technology works by routing pressurized carbon dioxide through compact heat exchangers to recover energy from turbine exhaust. Unlike traditional systems, this closed-loop method avoids the use of steam to drive power generation, improving energy extraction from gas-fired infrastructure. The startup plans to begin with a 10-megawatt unit before eventually expanding its application beyond gas turbines.
Timeline
2026: China commenced operations at the world's first supercritical carbon dioxide geothermal plant.
September 23, 2026: American Supercritical officially emerged from stealth.
2030: Projected global investment in data centers is expected to reach $7 trillion.
The Tech Race
The startup joins a small group of entities testing supercritical carbon dioxide as a high-efficiency alternative to conventional steam cycles. The project follows a development trajectory set by the Chinese geothermal plant, which demonstrated the viability of using supercritical CO2 for energy cycles earlier this year.
The technology aims to help data center operators manage energy scaling and emissions without shifting existing power infrastructure. Operators can expect to monitor the performance of the initial 10-megawatt units as a benchmark for potential large-scale deployment.
The takeaway
This technology represents a shift toward closed-loop thermal recovery as a primary method for curbing data center emissions. Observers should watch for the deployment schedule of the startup's first 10-megawatt unit as a key indicator of industrial scalability.
