What NET Power Inc. told the SEC could break it.
NET Power is a pre-revenue company whose core technology hasn't yet caught on: a third-quarter 2025 market analysis found slower-than-expected acceptance and deployment of its Oxy-Combustion Cycle, with costs above prior expectations, triggering a long-lived-asset impairment and a pivot toward gas turbines with licensed point-capture. Its demand thesis rests on a hard hurdle — to justify the cost of carbon capture, customers must be willing to pay a premium for clean power over unabated natural-gas power, a willingness that softens as agencies like the DOE and EPA de-emphasize clean-energy and greenhouse-gas priorities. And its project economics lean on policy: the 45Q carbon-capture tax credit (up to $85/ton), where the EPA's proposed removal of the greenhouse-gas reporting program could challenge the ability to claim 45Q for non-EOR sequestration.
3 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Other disclosures
- demand depends on customers paying a premium for clean power vs unabated gasmedium
To justify carbon-capture costs, NET Power's customers must be willing to pay a premium for clean power over unabated natural-gas power — a demand hurdle worsened as agencies like the DOE and EPA de-emphasize clean-energy/GHG priorities.
“In order to justify the cost of including carbon capture technology in our projects, our customers must be willing to pay a premium for clean power as compared to the prevailing price of unabated natural gas-fueled power in the same market.”
SEC filing →As of 2026 - pre-commercial technology; slow Oxy-Combustion Cycle adoption (impairment triggered)medium
NET Power is pre-revenue; in Q3 2025 its market analysis found slower-than-expected acceptance and deployment of its core Oxy-Combustion Cycle (with costs above prior expectations), triggering a long-lived-asset impairment and a pivot toward gas turbines + licensed PCC.
“During the third quarter of 2025, the Company completed a market analysis of the Oxy-Combustion Cycle, identifying slower than anticipated acceptance and deployment of the technology from previous expectations coupled with costs not cu”

Regulatory & policy
- dependence on 45Q carbon-capture tax credits and GHGRP/subpart RR reportingmedium
NET Power's economics rely on the 45Q carbon-capture tax credit (up to $85/ton); the EPA's proposed removal of the GHGRP threatens the ability to claim 45Q for saline (non-EOR) sequestration, creating regulatory uncertainty for project value.
“Removal of the GHGRP without further legislative or regulatory action may challenge the long-term ability to claim 45Q, though projects sequestering CO2 via EOR have a clear legal pathway even under the current uncertainty.”
