  • Electric vehicle cost breakdown by component?

    Electric vehicle cost breakdown by component?

    This data-file disaggregates the $30k total cost of a typical new ICE and the c$45k total cost of a typical new EV, as a sum-of-the-parts, across 25 cost lines. Drivetrain costs are similar at $8-9k each. The key challenge for the EV is the battery. The electric vehicle cost breakdown shows promise for improving power…

  • Lithium ion batteries: energy density?

    Lithium ion batteries: energy density?

    Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy densities doubling to 500Wh/kg in the 2030s, trebling to 750 Wh/kg by the 2040s, and the best possible energy densities are around 1,250 Wh/kg. This…

  • Global vehicle fleet: vehicle sales and electrification by region?

    Global vehicle fleet: vehicle sales and electrification by region?

    We have modeled the global light vehicle fleet, light vehicle sales by region, and the world’s shift from internal combustion engines (ICEs) towards electric vehicles (EVs) through 2050. Our base case model sees almost 200M EV sales by 2050, and a c40% decline to around 1bn combustion vehicles in the world’s fleet by 2050.

  • Magnets and energy: fundamental attraction?

    Magnets and energy: fundamental attraction?

    Electric currents create magnetic fields. Moving magnets induce electric currents. These principles underpin 95% of global electricity, while 50% of wind turbines and 95% of electric vehicles use permanent magnets with Rare Earth metals. This 15-page overview of magnets explains key magnet concepts and controversies for the energy transition.

  • Energy of rotation: angular momentum, inertia and flywheels?

    Energy of rotation: angular momentum, inertia and flywheels?

    This data-file calculates the energy stored in rotating masses. This includes 50Wh – 100 kWh flywheels. In power grids, the angular momentum of large rotating generators is known as ‘inertia’ and can run from 30kWh to 30MWH per turbine. Inertia has historically been a crucial part of stabilizing grids. Hence how do the physics work?…

  • Electrical conductivity: energy transition materials?

    Electrical conductivity: energy transition materials?

    Electrical conductivity of energy transition materials is tabulated in this data-file. ‘The action’ takes place in the range of 10^-8 to 10^-3 Ohm-meters, including silver in solar cells, copper in renewables and EVs, aluminium transmission lines, batteries, and solar semiconductors.

  • Capacitor banks: the economics?

    Capacitor banks: the economics?

    This model captures the economics of power factor correction via installing capacitor banks upstream of inductive loads. A 10% IRR is derived from a system costing $30/kVAR, reducing real power losses by 0.5%, thus saving on 8c/kWh electricity prices (75% of savings), $3.5/kW demand charges (15%) and a $20/ton CO2 price (10%).
