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.

Adiabatic flame temperature: hydrogen, methane and oil products?
At an idealized, 100% stoichiometric ratio, the adiabatic flame temperature for natural gas is 1,960ºC, hydrogen burns 300ºC hotter at 2,250ºC and oil products burn somewhere in between, at around 2,150ºC. The calculations show why hydrogen cannot always be dropped into an existing turbine or heat engine.

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.

European gas and power model: natural gas supply-demand?
European gas and power markets will look better-supplied than they truly are in 2023-24. A dozen key input variables can be stress-tested in the data-file. Overall, we think Europe will need to source over 15bcfd of LNG through 2030, especially US LNG.

Industrial cooling: chillers and evaporators?
This data-file captures the costs of industrial cooling, especially liquid cooling using commercial HVAC equipment, across heat-exchangers, cooling tower evaporators and chillers. Our base case is that removing 100MW-th of heat has capex costs of $1,000/ton, equivalent to c$300/kW-th, expending 0.12 kWh-e of electricity per kWh-th, with a total cost of 7 c/ton-hour.

District heating: the economics?
District heating can lower CO2 intensity, by piping waste heat from power generation or industry to consumers. Costs can vary by a factor of 10x. But our base case estimates a 10% IRR at 10c/kWh retail heating price. Please download the model to flex gas prices, household consumption rates or costs.

LNG liquefaction technologies: an overview?
This data-file is an overview of different LNG liquefaction technologies: APCI, APX, Optimised Cascade, Fluid Cascade, DMR, SMR, PRICO and MMLS. A typical LNG liquefaction plant has energy intensity of 280kWh/ton, consuming 5% of the input gas entering the plant, with 20kg/boe of Scope 1&2 CO2 intensity. But efficient and electric-drive compression can lower these…

Combined heat and power: the economics?
This data-file models the energy economics of a combined heat and power installation, to provide electricity and heating behind the meter, in lieu of purchasing electricity from the grid. Economics are strong, especially for larger units. CO2 emissions can also be reduced by 5-30% due to high efficiency.

Harmonic filters: leading companies?
This data-file screens 20 leading companies in harmonic filters, tabulating their size, geography, ownership details, patent filings and a description of their offering. Active harmonic filters reduce total harmonic distortion below 5%, with 97% efficiency, within 5 ms. Half a dozen companies stood out in our screen, including one large, listed Western capital goods company.
