NET Power’s Patented Thermodynamic Cycle:

The Allam-Fetvedt Cycle
Learn How It Works & How It Compares To Traditional Natural Gas Power Plants

La Porte, Texas

50MWth Demonstration Facility

 

Our La Porte plant plant proves that NET Power can provide clean energy with zero emissions.

Commercially sold CO2 drives lower-cost, carbon-sequestering enhanced oil recovery, sour gas clean up, production of concrete and plastics…while subsidizing cheaper, clean electricity.

We make existing power plants
economically and environmentally obsolete.

Zero
Emissions

No air pollutants.

Lower
Power Costs

Since the Allam-Fetvedt Cycle uses CO2 instead of steam to drive its turbine, the efficiency and life span is better than existing natural gas power plants.

Complements
Renewables

NET Power is the perfect zero emissions match for intermittent renewable energy thanks to its inherent energy storage capabilities and output flexibility.

Multiple
Revenue Streams

Rather than emitting greenhouse gases, industrially useful and valuable CO2 is captured and salable, along with other industrial gas byproducts (Argon and Nitrogen). Qualifies for 45Q carbon capture tax credit.

Made for
Anywhere

The NET Power technology solution is tailored to market needs: it complements current infrastructure, available in multiple size variations, compatible with low-grade fuels, capable of water-free production, a significantly smaller land footprint and universally permittable.

Our differentiation is unequalled.

NET Power vs the Traditional Fossil Fuel Power Plant

NET Power Plant

Traditional Fossil Fuel Power Plant

Fuel is burned with pure oxygen.

This creates CO2 that is sent through the rest of the cycle. New CO2 is captured and the remaining 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 over and over again, which helps efficiency and makes the cost of electricity lower.
The cycle doesn’t maintain custody of its CO2, and burns natural gas in the presence of atmospheric gases, which results in emissions.
Excess CO2 that’s created through the cycle is pipeline & commercially-ready to be sold to crucial industries (e.g. oil recovery, industrial and agricultural feedstock) – this enhances the value of the power plant.
The byproducts of this cycle are toxic to the environment and add to the globe’s rising temperatures. The only positive byproduct is electricity.

The 4 Steps To Cleaner Energy:
How The Allam-Fetvedt Cycle Works

 

The Allam-Fetvedt Cycle is pretty simple.

It burns natural gas with pure oxygen, and the resulting CO2 is sent through the combustor, turbine, heat exchanger, and compressor, altogether creating low-cost energy. Extra CO2 that’s produced is pipeline ready and sold to industries who need it, such as the medical, agricultural, and industrial sectors. It can also be cheaply sequestered.

Here’s a more thorough break-down of the process:

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 COmoves 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, and can be sold to industries who need it or simply sequestered.

This step increases Allam-Fetvedt Cycle Power Plant’s overall financial value by providing a valuable byproduct and eliminating any carbon-related liabilities.

Altogether, these 4 steps boast:

Low-cost energy
Low water use
Zero air emissions
