Zero Emissions Power from Natural Gas

NET Power’s semi-closed loop technology leverages oxy-combustion to produce emissions-free power.

NET Power technology 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.

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
The high-pressure CO2 moves along into the turbine, where it expands and goes into the heat exchanger.

Any water is removed, and the remaining CO2 is compressed and pumped back into high-pressure.

Step 3
Reuse & Recycle
Most of the high-pressure CO2 is reheated in the heat exchanger and returned to the combustor, where the whole cycle begins again.
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 Plant:
NET Power Technology
Notice anything different?
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

The cycle reuses CO2 which drives efficiency and reduces the cost of electricity
The cycle does not maintain custody of its CO2 and creates other emissions by burning natural gas in the presence of atmospheric gases

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

The byproducts of this cycle are toxic to the environment and contribute to the globe’s rising temperatures; the only positive byproduct is electricity
Land usage of <13 acres (>40% less than similar output natural gas plant)
Average land usage of 20–25 acres
