Hydrogen: overview and conclusions?
We think the best opportunities in hydrogen will be to decarbonize gas at source via blue and turquoise hydrogen, displacing ‘black hydrogen’ that currently comes from coal, and to produce small-scale feedstock on site via electrolysis for select industries. Others see green hydrogen as a cornerstone of the future energy system. We think there may…

Costs of hydrogen from coal gasification?
What are the costs of hydrogen from coal gasification? This model looks line-by-line, across different plant configurations, aggregating data from technical papers. Black hydrogen costs $1-2/kg. But CO2 intensity is very high, as much as 25 tons/ton. It can possibly be decarbonized resulting in semi-clean hydrogen costing c$2.5/kg.

Pressure ratings: industrial and energy processes?
The purpose of this data-file is to chart the typical pressures of industrial processes and energy processes, as a useful reference. We are all used to 1 atmosphere of pressure, which is 1.0125 bar, 0.10125 MPa and 14.7 psi. But what pressures do industrial processes use?

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.

Fuel costs and CO2 intensities?
We have produced a cross-plot of the costs and CO2 intensities of different fuels, in $/boe and kg of CO2 per boe, to compre the relative attractiveness of decarbonization options. Favored decarbonization options are nature based solutions, CO2-EOR, blue hydrogen and coal-to-gas switching.

Plastic products: energy and CO2 intensity of plastics?
The energy intensity of plastic products and the CO2 intensity of plastics are built up from first principles in this data-file. Virgin plastic typically embeds 3-4 kg/kg of CO2e. But compared against glass, PET bottles embed 60% less energy and 80% less CO2. Compared against virgin PET, recycled PET embeds 70% less energy and 45%…

Renewable diesel: the economics?
Our base case is that a US renewable diesel facility must achieve $4.6/gallon sales revenues (which is c$200/bbl) as it commercializes a product with up to 75% lower embedded emissions than conventional diesel. Similarly, a bio-diesel facility must achieve $3.6/gallon sales on a product with 60% lower embedded emissions.

Organic Rankine Cycles: the energy economics?
This data-file captures the energy economics of an Organic Rankine Cycle to recover low-grade waste heat (at 70-200C) from an industrial facility, or in the geothermal industry. A CO2 price of $50-75/ton could greatly accelerate adoption and improve the efficiency of industrial facilities.
