  • 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%).

  • Variable frequency drives: leading companies?

    Variable frequency drives: leading companies?

    This data-file outlines the top twenty companies producing variable frequency drives to precisely control electric motors. The top three companies are European capital goods players. High-quality VFDs may protect against growing competition from China.

  • Variable frequency drives: the economics?

    Variable frequency drives: the economics?

    Variable frequency drives optimize the operating speeds of electric motors. Average energy saving are 34% and average costs are $250/kW. Hence our modelling calculates >15% IRRs installing a VFD at a typical industrial motor. This data-file captures the economics.

  • Energy economics: an overview?

    Energy economics: an overview?

    This data-file provides an overview of energy economics, across 175 different economic models constructed by Thunder Said Energy, in order to put numbers in context. This helps to compare marginal costs, capex costs, energy intensity, interest rate sensitivity, and other key parameters that matter in the energy transition.
