The 4 Steps To Advanced Clean Energy
How NET Power Technology Works
NET Power technology is pretty simple.
It burns natural gas with pure oxygen.
The resulting CO2 is recycled through the combustor, turbine, heat exchanger, and compressor,
creating lower-cost power with zero emissions.
Captured CO2 is pipeline ready and can either be cheaply sequestered
or sold to industries such as the medical, agricultural, and industrial sectors.
Step 1
The Burn
Oxy-combustion is the process of burning natural gas with pure oxygen (instead of air).
When air is used as the primary oxidant, nitrogen oxides (NOX) are released into the atmosphere. This isn’t only bad for the environment – it’s also less efficient.
When pure oxygen is the primary oxidant, fuel consumption is reduced, and flame temperatures are increased, adding efficiency.
Step 2
The Expansion & Cooldown
Any water is removed, and the remaining CO2 is compressed and pumped back into high-pressure.
Step 3
Reuse & Recycle
Step 4
Piping
The excess CO2 that comes from step 2 is pipeline ready. It’s inherently captured, not released into the atmosphere.
This step increases NET Power technology’s overall value by providing a valuable byproduct and eliminating any carbon-related liabilities.

NET Power vs. Conventional Natural Gas Power Plant
NET Power Plant:
NET Power Technology
Conventional Natural Gas Power Plant
Combined Cycle Gas Turbine
Natural gas is burned with pure oxygen
This creates CO2 that is sent through the rest of the cycle
New CO2 is captured and the remainder is recycled –nothing is released into the atmosphere
Fuel is burned in air
This creates NOX emissions, and the resulting CO2 is sent into the atmosphere unless it is cleaned by expensive post-combustion carbon capture
Excess industrial gases created through cycle are pipeline and commercially-ready to be sold to crucial industries (e.g. industrial and agricultural feedstock), enhancing the value of the power plant

New CO2 is captured and the remainder is recycled –nothing is released into the atmosphere
The cycle reuses CO2 which drives efficiency and reduces the cost of electricity

Land usage of <13 acres (>40% less than similar output natural gas plant)
Conventional Natural Gas Power Plant
Combined Cycle Gas Turbine
Fuel is burned in air
This creates NOX emissions, and the resulting CO2 is sent into the atmosphere unless it is cleaned by expensive post-combustion carbon capture
The cycle does not maintain custody of its CO2 and creates other emissions by burning natural gas in the presence of atmospheric gases
The byproducts of this cycle are toxic to the environment and contribute to the globe’s rising temperatures; the only positive byproduct is electricity
Average land usage of 20–25 acres
