VALUE ADDED STEAM TECHNOLOGIES

The VAST
Power Cycle

A patented rethinking of the gas turbine — wet combustion designed to deliver more power, lower emissions, and unmatched fuel flexibility from a smaller footprint.

VAST's gas turbine technology is conceptual and pre-commercial — validated through national-lab research and simulation, with no product yet available for purchase.
HOW IT WORKS

Clean combustion.
Explained simply.

The VASThermogenerator burns fuels in a fundamentally different way. Instead of letting combustion run hot and dirty, it injects water and steam directly into the combustion zone to cool it — preventing the formation of NOx before it ever starts.

The result is VASTgas: a working fluid of nitrogen, CO₂, and steam. As water flashes to steam, it recaptures latent heat through the patented Wet Combustion Cycle, keeping the burning zone below 2,300°F while extracting maximum energy from every molecule of fuel.

The exhaust is so clean you can breathe it — under 1 ppm NOx and CO, without expensive after-treatment systems.

FOUR PILLARS

Core technologies

Patented innovations that work together to outperform conventional Brayton cycles in every metric that matters.

Wet Combustion

Water and steam injected directly into the combustion zone — radically cooling the flame front while recapturing latent heat for higher efficiency.

  • Omega ratio >10:1
  • Stable combustion below 700°C
  • <1 ppm NOx and CO
  • Multi-fuel capable

Fluid Mixing

Precision multi-fluid mixing ensures uniform combustion across the entire flame zone — the key to stability and ultra-low emissions.

  • Multi-fluid mixing architecture
  • Enhanced combustion stability
  • Lower emissions across load range

Wet Compression

Stage water injection during compression reduces the air mass required, enabling higher pressure ratios from a smaller physical footprint.

  • Stage water injection
  • Less air required per MW
  • Smaller plant footprint
  • Higher pressure ratios

Power Cycles

Integrated water recovery and recycling closes the thermodynamic loop — increasing net power output while driving emissions even lower.

  • Water recovery and recycling
  • Increased net power output
  • Lower overall emissions
  • Excellent peaker plant economics
BEYOND POWER GENERATION

Hydrocarbon Extraction
& EOR

The VAST cycle doesn't just generate electricity — it produces a high-value exhaust stream that can be put directly to work in enhanced oil recovery and hydrocarbon extraction operations.

VAST delivers exhaust heat, steam, and CO₂ downhole — turning what conventional turbines waste into a revenue-generating resource for oil and gas operators pursuing carbon-aware production.

Exhaust Heat

High-temperature thermal energy for downhole processes and facility heating.

Steam

On-demand steam injection for thermal EOR and reservoir stimulation.

CO₂

Concentrated CO₂ stream for carbon flooding and sequestration applications.

One platform — power generation and hydrocarbon extraction — eliminating the need for separate heat, steam, and CO₂ supply systems.
