Ethane cracking: the economics?
This data-file captures the economics of ethane-cracking to produce ethylene. A typical US Gulf Coast facility could generate 15% IRRs at typical capex cost of $1,135/Tpa. CO2 intensity can be as high as 1.7T of CO2 per ton of ethylene, or potentially much lower depending on the facility’s energy efficiency.

Air conditioning: energy demand sensitivity?
This data-file quantifies air conditioning energy demand. In the US each 100 variation in CDDs adds 26 TWH of electricity (0.6%) demand and 200bcf of gas (0.6%). Air conditioning already consumes 7% of all global electricity and could treble by 2050.

Crop production: what CO2 intensity?
The CO2 intensity of producing corn averages 0.23 tons/ton, or 75kg/boe. 50% is from N2O emissions, a powerful greenhouse gas, from the breakdown of nitrogen fertilizer. Producing 1 kWh of food energy requires 9 kWh of fossil energy.

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.

CCS: amine degradation rates?
In post-combustion CCS facilities, amines react with CO2, which can later be re-released via steam-treating, and sent for sequestration. However, CCS plants have amine make-up rates, to replace amines that degrade (chemically, thermally) and evaporate off. This data-file quantifies make-up rates of amines in kg/ton.

Selective catalytic reduction: costs of NOx removal?
This data-file captures selective catalytic reduction costs to remove NOx from the exhaust gas of combustion boilers and burners. Our base case estimate is 0.25 c/kWh at a combined cycle gas plant, which equates to $4,000/ton of NOx removed. Capex costs, operating costs, coal plants and marine fuels can be stress-tested in the model.

Metals and materials: strength and temperature resistance?
This data-file aggregates information into the strength, temperature resistance, rigidity, costs and CO2 intensities of important metals and materials. These are used in gas turbines, wind turbines, pipelines, CCS, power transmission.

CO2 intensity of materials: an overview?
This data-file tabulates the energy intensity and CO2 intensity of materials, in tons/ton of CO2, kWh/ton of electricity and kWh/ton of total energy use per ton of material. The build-ups are based on 160 economic models that we have constructed to date, and simply intended as a helpful summary reference. Our key conclusions on CO2…

Energy needed to produce steam: enthalpy and entropy data?
This data-file quantifies the energy needed to produce steam, for industrial heat, chemicals, CCS plants and hydrogen reforming? As rules of thumb, low pressure saturated steam at 100◦C requires 2.6 GJ/ton (720kWh/ton), medium pressure dry steam at 6-bar and 300◦C requires 3 GJ/ton (830kWh/ton) and super-critical steam at 250-bar and 600◦C requires 4 GJ/ton (1,150kWh/ton).

Boltzmann energy overview?
The Boltzmann constant, denoted as kB, or 1.381 x 10^-23 J/K, is the most important number in thermodynamics. It denotes the rate at which a single particle will gain thermal energy (in Joules) as its absolute temperature rises (in Kelvin). It underpins the Boltzmann distribution and the Maxwell-Boltzmann distributions, which matter in modelling gases, energy…
