  • Load profiles in power grids?

    Load profiles in power grids?

    Load profiles depict how the power running through a particular cross-section of the grid varies over time, ranging from individual homes, through giant GVA-scale transmission lines. Load profile data are unfortunately not widely available, however, we have aggregated a dozen case studies from technical papers, in this data-file, to help decision-makers with grid-modeling.

  • US energy consumption by State and by source?

    US energy consumption by State and by source?

    Total useful energy consumption in the US runs at 12,500 TWH pa, or 37 MWH pp pa. But this data-file disaggregates useful US energy consumption by State and by energy source, from 2000 to 2024. The US energy system is not a monolith, but full of amazing regional variation.

  • Wildfire suppression companies?

    Wildfire suppression companies?

    1-2bn acres of land burns globally each year, which could increase by over 35% due to climate change. Hence this data-file screens emerging companies in wildfire suppression, which are focused on preventing, detecting and containing wildfires. The most commonly used methods are drones and AI. Thus adapting to climate change requires more energy not less?

  • 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…

  • 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.

  • Residential energy prices: reasons for optimism?

    Residential energy prices: reasons for optimism?

    Residential energy prices tend to run 4x higher than underlying wholesale energy prices. This is a very wide margin, as by contrast, typical commoditized products in supermarkets are usually only marked up by about 2x, compared to their wholesale prices. Today’s data-file compares retail prices vs wholesale prices across a dozen different categories. A remarkable…

  • Hydrofluoric acid: the economics?

    Hydrofluoric acid: the economics?

    Hydrogen fluoride is a crucial commodity chemical. This model captures its production from acid-grade fluorspar and sulfuric acid. We think marginal costs are around $1,850/ton, in order to earn a 10% IRR on a production facility costing $4,000/Tpa, while the fully loaded CO2 intensity is around 0.75 tons/ton.

  • Power grids: hell is a hot, still summer’s day?

    Power grids: hell is a hot, still summer’s day?

    Ramping renewables to 50% of power grids is a growing aspiration in the energy transition. But in some markets, it may result in devastating blackouts during summer heatwaves, as power demand doubles exactly when wind, solar, gas, transmission losses and disruptions all deteriorate. This 15-page note assesses the implications.

  • Windy physics: how is power of a wind turbine calculated?

    Windy physics: how is power of a wind turbine calculated?

    This data-file is an overview of wind power physics. Specifically, how is the power of a wind turbine calculated, in MW, as a function of wind speed, blade length, blade number, rotational speed (in RPM) and other efficiency factors (lambda). A large, modern offshore wind turbine will have 100m blades and surpass 10MW power outputs.

  • Power plants: average capacity?

    Power plants: average capacity?

    This data-file aggregates granular data into the average capacity of different types of power plants: wind, solar, nuclear, gas, hydro, coal, biomass, landfill gas and geothermal. Energy transition is going to increase the number of inter-connections to the grid by 10-100x.
