  • LNG plant compression: gas drives vs electric motors?

    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.

  • Axial flux motors: leading companies and products?

    Axial flux motors: leading companies and products?

    This data-file profiles leading companies and products in the space of axial flux motors, with an average power density of almost 8kW/kg, which is 10x higher than a typical AC induction motor in heavy industry. Leading companies are profiled, based on reviewing over 1,200 patents.

  • Energy efficiency of motors and power generators?

    Energy efficiency of motors and power generators?

    This data-file estimates the efficiency of electric motors and power generators, using specific examples and data-points. This matters as there are around 50bn motors in the world, consuming c45% of global electricity. Efficiency ratings are generally high, above 90%, although lagging and non-optimized motors can be in the 70-80% range.

  • Electric vehicles: motors and magnets?

    Electric vehicles: motors and magnets?

    This data-file assesses electric vehicle magnets, permanent magnets and the use of Rare Earth materials such as neodymium (NdFeB). 80-90% of recent EVs have used Rare Earth permanent magnets, averaging 1.5 kg per vehicle, or 7.5g/kW of drive-train power, across the data-file. But the numbers vary vastly. From 0-4 kg per vehicle. 20 vehicles from…

  • Electric motors: state of flux?

    Electric motors: state of flux?

    This 15-page note explores whether axial flux motors could come to dominate in the future of transportation. They promise 2-3x higher power densities, even versus Teslaโ€™s world-leading PMSRMs; and 10-15x higher than clunky industrial AC induction units; while also surpassing c96% efficiencies.

  • Electric motors: variable star?

    Electric motors: variable star?

    Variable frequency drives precisely control motors. Amazingly they could reduce global electricity demand by c10%. We expect a sharp acceleration due to sustained energy shortages, increasingly renewable-heavy grids and excellent 20-50% IRRs. Hence this 14-page note reviews the opportunity and who benefits.ย

  • Power grids: opportunities in the energy transition?

    Power grids: opportunities in the energy transition?

    Power grids move electricity from the point of generation to the point of use, while aiming to maximize the power quality, minimize costs and minimize losses. Broadly defined, global power grids and power electronics investment must step up 5x in the energy transition, from a $750bn pa market to over $3.5trn pa. But this theme…

  • 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…
