  • Weatherization of homes: what methods and costs?

    Weatherization of homes: what methods and costs?

    The weatherization of 2M American homes is part of Joe Biden’s proposed energy policy, in order to reduce heating costs and emissions. Hence, this data-file estimates the costs and payoffs of attic insulation, air sealing, window upgrades, window coverings and smart thermostats.

  • Thermodynamics of CO2 at different temperatures and pressures?

    Thermodynamics of CO2 at different temperatures and pressures?

    This data-file aggregates thermodynamic properties of CO2 at different temperatures and pressures. Specifically, how do different pressures and temperatures dictate CO2’s density, Cp, Cv, Heat Capacity Ratio (gamma), Entropy, and Compressibility. These variables matter for CO2 compression, CCS and sCO2 power cycles.

  • Gas turbines: operating parameters?

    Gas turbines: operating parameters?

    A typical simple-cycle gas turbine is sized at 200MW, and achieves 38% efficiency, as super-heated gases at 1,250ยบC temperature and 100-bar pressure expand and drive a turbine. Efficiency rises to 58% in a combined cycle. The purpose of this data-file is to tabulate typical operating parameters of gas turbines.

  • Thermal power plant: loss attribution?

    Thermal power plant: loss attribution?

    This data-file is a simple loss attribution for a thermal power plant. For example, a typical coal-fired power plant might achieve a primary efficiency of 38%, converting thermal energy in coal into electrical energy. Our loss attribution covers the other 62% using simple physics and industry average data-points.

  • Acetylene: production costs?

    Acetylene: production costs?

    Acetylene production costs are broken down in this data-file, estimated at $1,425/ton for a 10% IRR on a petrochemical facility that partially oxidizes the methane molecule. CO2 intensity is over 3 kg/kg. Up to 12MTpa of acetylene is produced globally for welding and as a petrochemical building block.

  • Energy Recovery Inc: pressure exchanger technology?

    Energy Recovery Inc: pressure exchanger technology?

    Pressure exchangers transfer energy from a high-pressure fluid stream to a low-pressure fluid stream, and can save up to 60% input energy. Energy Recovery Inc is a leading provider of pressure exchangers, especially for the desalination industry, and increasingly for refrigeration, air conditioners, heat pump and industrial applications. Our technology review finds a moat.

  • Density of gases: by pressure and temperature?

    Density of gases: by pressure and temperature?

    The density of gases matters in turbines, compressors, for energy transport and energy storage. Hence this data-file models the density of gases from first principles, using the Ideal Gas Equations and the Clausius-Clapeyron Equation. High energy density is shown for methane, less so for hydrogen and ammonia. CO2, nitrogen, argon and water are also captured.

  • Global energy demand by end use?

    Global energy demand by end use?

    This data-file is a breakdown of global energy demand by end use, drawing across our entire research library, to disaggregate the global energy system across almost 50 applications, across transportation, heat, electricity, materials and manufacturing. Numbers, calculations, efficiencies and heating temperatures are in the data-file.

  • Vehicle emissions of CO, NOx and HCs?

    Vehicle emissions of CO, NOx and HCs?

    There has been a remarkable reduction in the negative air quality impacts of combustion vehicles since 1970, as quantified in this data-file and over time. Vehicle emissions of CO, NOx and HCs have all fallen by 20-60x over the past 50-years, to 5 grams/mile, 0.2 grams/mile and 0.3 grams per mile, respectively. This data-file quantifies…
