  • Compressor costs: a simple overview?

    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.

  • Gas turbines: operating parameters?

    Gas turbines: operating parameters?

    A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ยบC 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.

  • US gas transmission: by company and by pipeline?

    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.

  • Compressed air energy storage: costs and economics?

    Compressed air energy storage: costs and economics?

    Our base case estimates for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year. Our numbers are based on top-down project data and bottom up calculations, both for CAES capex (in $/kW) and…

  • LNG liquefaction technologies: an overview?

    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…

  • CO2-EOR in Shale: the economics

    CO2-EOR in Shale: the economics

    We model the economics for CO2-EOR in shales, after interest in this topic spiked 2.3x YoY in the 2019 technical literature. We see 15% IRRs in our base case, creating $1.6M of incremental value per well, uplifting type curves by 1.75x. Greater upside is readily possible. Most exciting is the prospect for Permian EOR to…

  • Gas power: levelized costs of combined cycle gas turbines?

    Gas power: levelized costs of combined cycle gas turbines?

    Levelized costs of combined cycle gas turbines are built up in this data-file. Our base case costs of gas-fired power generation are 8c/kWh, at a combined cycle turbine converting 55% of the thermal energy of natural gas into electrical energy, for a total CO2 intensity of 0.35 kg/kWh.

  • Fugitive methane: what components are leaking?

    Fugitive methane: what components are leaking?

    This data-file looks through 35 technical papers to tabulate methane leaks from different components around the oil and gas industry. The largest are losses of well control (up to 1MTpa), then mid-downstream facilities (up to 10kTpa), compressors (up to 100T), pneumatic devices, wellheads and liquid unloading (up to 10T).

  • Leading Companies in Pipeline Gas Technology?

    Leading Companies in Pipeline Gas Technology?

    This data-file tracks 800 patents innovating pipeline transportation of natural gas, to screen for exciting technologies and companies. 6 publicly listed firms and 6 venture-stage start-ups stood out from the analysis, commercialising next-generation materials, monitoring methods and optimizing gas distribution.

  • Gas pipelines, CO2 pipelines, hydrogen pipelines?

    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.
