  • 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…

  • Thermodynamics of CO2 at different temperatures and pressures?

    Thermodynamics of CO2 at different temperatures and pressures?

    This data-file aggregates thermodynamic properties of CO2 at different temperatures and pressures. Specifically, how do different pressures and temperatures dictate CO2’s density, Cp, Cv, Heat Capacity Ratio (gamma), Entropy, and Compressibility. These variables matter for CO2 compression, CCS and sCO2 power cycles.

  • Mainspring Energy: linear generator breakthrough?

    Mainspring Energy: linear generator breakthrough?

    Linear generator technology can convert any gaseous fuel into electricity, with c45% electrical efficiency, and >80% efficiency in CHP mode. This data-file reviews Mainspring Energy’s patents. We conclude that the company has locked up the IP for piston-seal assemblies in a linear generator with air bearings, but longevity/maintenance could be a key challenge to explore.

  • NEL: green hydrogen technology review?

    NEL: green hydrogen technology review?

    NEL is a green hydrogen technology company, headquartered in Oslo, listed on the Oslo Bรธrs since 2014, and employing 575 people. It has manufactured 3,500 electrolyser units, going back to 1927, historically weighted to alkaline electrolysers, and increasingly focused on PEMs and hydrogen fuelling stations. This NEL technology review explores its patents.

  • Hot potassium carbonate CCS: energy economics?

    Hot potassium carbonate CCS: energy economics?

    Hot potassium carbonate is a post-combustion CCS technology that bypasses the degradation issues of amines, and can help to decarbonize power, BECCS and cement plants. We think costs are around $100/ton and energy penalties are 30-50%. Potassium carbonate CCS can be stress-tested in this data-file, across 50 inputs.

  • Pressure swing adsorption: energy economics?

    Pressure swing adsorption: energy economics?

    Pressure swing adsorption purifies gases according to their differing tendencies to adsorb onto adsorbents under pressure. Pressure swing adsorption costs $0.1/kg when separating pure hydrogen from reformers, and $2-3/mcf when separating bio-methane from biogas. Our cost breakdowns include capex, opex, maintenance, zeolite replacement, compression power and CO2 costs.

  • 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).
