Compressor costs: a simple overview?
This data-file aims to give a helpful, basic overview of the $40bn pa compressor market, between centrifugal, reciprocating and screw compressors. A typical industrial unit is 50kW and costs $850/kW on an installed basis. Companies and efficiency calculations are also given.

LNG plant compression: gas drives vs electric motors?
This data-file compares the costs of refrigerant compression at LNG plants, using gas turbines, electric motors powered by on-site CCGTs, or electric motors powered by renewable electricity. eLNG has higher capex costs, but higher efficiency, lower opex, and short payback times. Numbers in $/mcf and $/MTpa can be stress-tested in the data-file.

Gas turbines: operating parameters?
A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ºC temperature and 100-bar pressure expand and drive a turbine. Efficiency rises to 58% in a combined cycle. The purpose of this data-file is to tabulate typical operating parameters of gas turbines.

CO2 compression: stranger things?
CO2 is a strange gas. This matters as energy transition will require over 120 GW of compressors for 6GTpa of CCUS. This 13-page notes explains CO2’s strange properties, which helps to fine-tune appropriate risking factors for vanilla CCS, blue hydrogen, CO2-EOR, CO2 shipping, super-critical CO2 power cycles. There is also a wide moat around leading…

Density of gases: by pressure and temperature?
The density of gases matters in turbines, compressors, for energy transport and energy storage. Hence this data-file models the density of gases from first principles, using the Ideal Gas Equations and the Clausius-Clapeyron Equation. High energy density is shown for methane, less so for hydrogen and ammonia. CO2, nitrogen, argon and water are also captured.

LNG plant compressors: chilling goes electric?
Electric motors were selected, in lieu of industry-standard gas turbines, to power the main refrigeration compressors at three of the four new LNG projects that took FID in 2024. Hence is a major change underway in the LNG industry? This 13-page report covers the costs of e-LNG, advantages and challanges, and who benfits from shifting…

Pressure ratings: industrial and energy processes?
The purpose of this data-file is to chart the typical pressures of industrial processes and energy processes, as a useful reference. We are all used to 1 atmosphere of pressure, which is 1.0125 bar, 0.10125 MPa and 14.7 psi. But what pressures do industrial processes use?

US gas transmission: by company and by pipeline?
This data-file aggregates granular data into US gas transmission, by company and by pipeline, for 40 major US gas pipelines which transport 45TCF of gas per annum across 185,000 miles; and for 3,200 compressors at 640 related compressor stations.

LNG liquefaction technologies: an overview?
This data-file is an overview of different LNG liquefaction technologies: APCI, APX, Optimised Cascade, Fluid Cascade, DMR, SMR, PRICO and MMLS. A typical LNG liquefaction plant has energy intensity of 280kWh/ton, consuming 5% of the input gas entering the plant, with 20kg/boe of Scope 1&2 CO2 intensity. But efficient and electric-drive compression can lower these…

Gas pipelines, CO2 pipelines, hydrogen pipelines?
This model captures the energy economics of a pipeline carrying natural gas, CO2 or hydrogen. It computes the required throughput tariff (in $/mcf or $/kg) to earn a 10% IRR. Hydrogen tariffs must be 2x new gas pipelines and 10x pre-existing gas pipelines. CO2 disposal is more economic at scale.
