Major industrial users of compressed air include chemicals, metals, petroleum, transportation equipment, mining, construction, and various other manufacturing sectors.  Additionally, compressed air systems are also widely used in medical applications, power generation, wastewater treatment, and agriculture.



Cost Reduction

Compressed air systems consume approximately 10% of US industrial electricity. With an approximate 10% conversion of energy input into useful output, compressed air systems are extremely inefficient, resulting in high energy costs for their users, and high greenhouse gas emissions.  According to CAGI, greater than 1,000 metric tons of greenhouse gas emissions are created for each 1,000HP compressor system in operation.


  • Based on data from the US DOE, US industrial compressed air systems consume approximately 80,000 – 90,000 Gigawatt hours of electricity annually in the US, which translates into annual electricity costs in excess of $5 billion.
  • Air and Gas Compressors are estimated to consume 175,000 Gigawatt hours of electricity in the EU, which translates into annual energy costs of over $14 billion.


Compression systems are an integral component in Oil & Gas infrastructure.  Multiple applications for Carnot’s technology exist in wellhead/drilling, pipeline infrastructure, compressed natural gas, and liquefied natural gas applications.



  • Making marginal wells economically viable.
  • Extending the life of declining wells.
  • Flare recovery.
  • Cleaning “dirty” gas as it enters the pipeline infrastructure.
  • Lower operating costs and fewer greenhouse gas emissions versus existing compression applications.



  • Approximately 5% of US Natural Gas production is consumed by gas compressors from the wellhead through the delivery system
  • Over 1 Trillion cubic feet of natural gas is used to power natural gas compression systems
  • This translates into lost sales for producers of over $5 billion annually
  • Gas compressors emit ~68 million metric tons of CO2
  • Carnot’s system will dramatically lower energy utilization for gas compression, leading to greater profits for producers and less emissions
  • No dewatering process is needed, as Carnot’s process naturally dries the gas.
  • Carnot’s process separates contaminants out of the natural gas as it enters a compression station, reducing the need for scrubbers and filters.
  • Isothermal compression eliminates the need for cooling prior to returning gas to a pipeline.



At current natural gas prices Compressed Natural Gas “CNG” is cheaper than either diesel or gasoline on a fuel equivalent basis.  Despite this cost advantage, CNG utilization for transportation applications is relatively limited in the US, with an undeveloped fueling infrastructure serving as an impediment to greater adoption.  Carnot’s technology could lower the infrastructure costs for CNG fueling, potentially driving enhanced investment in retail and fleet fueling stations and making home fueling stations economically viable for individuals.



Carnot’s technology can be applied to Liquefied Natural Gas “LNG” as well.  LNG demand is increasing worldwide.  In its 2014 Energy Outlook, Exxon Mobil states that LNG output is expected to triple through 2040, and will comprise approximately 15% of global gas demand in 2040.   The US is expected to be a net exporter of natural gas by 2020, driving demand for LNG export facilities.  Stricter environmental regulations for shippers are also a demand driver, with many large shipping companies considering investments in LNG as a transportation fuel.  Canot’s system would enable liquefaction with fewer compression stages, at significantly lower energy cost.


Compressed air systems are ubiquitous tools for civil construction crews.  With Carnot’s higher efficiency, crews can operate higher output compressors with prime movers that meet ever-increasing emissions standards for mobile units, such as California’s CARB regulations.


Approximately 1/3 of the electrical energy consumed each year in the United States is used by HVACR systems. Compressors are estimated to make up a majority of energy usage in these systems. Carnot’s superior energy efficiency positions it for applications across the spectrum of HVACR applications..


Multiple dynamics are driving market growth in energy storage, including: Increased renewable energy generating capacity, deferral of transmission & distribution  investments, substitution of energy storage for generating capacity investments, and grid stability and effectiveness. Carnot’s technolgy is well positioned to address this market.
