  • Wind turbine generators: DFIGs or Rare Earth magnets?

    Wind turbine generators: DFIGs or Rare Earth magnets?

    Wind turbines can use doubly fed induction generators (DFIGs) or permanent magnet synchronous generators (PMSGs) based around Rare Earth metals. This data-file captures the trends in DFIGs vs PMSGs over time by tabulating 40 examples, as turbines have grown larger, and different wind turbine manufacturers have adopted different strategies.

  • 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…

  • Bloom Energy: solid oxide fuel cell technology?

    Bloom Energy: solid oxide fuel cell technology?

    This data-file reviews Bloom Energy’s solid oxide fuel cell technology. What surprised us most was a candid overview of degradation pathways of solid oxide fuel cells, a focus on improving the longevity of fuel cells, albeit this sometimes seems to be via heavy uses of Rare Earth metals, and increasing complexity. The patents do suggest…

  • Overview of lasers: by type, market size and efficiency?

    Overview of lasers: by type, market size and efficiency?

    The global laser market is worth $20bn pa, of which half comprises diode lasers mainly used for fiber-optic communications and around 30% is fiber lasers mainly used for cutting, welding and heat-treating materials. These two laser types dominate because of their high, 30-80% efficiencies. This data-file is a brief overview of lasers.
