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.

Heavy truck costs: diesel, gas, electric or hydrogen?
Heavy truck costs are estimated at $0.14 per ton-kilometer, for a truck typically carrying 15 tons of load and traversing over 150,000 miles per annum. Today these trucks consume 10Mbpd of diesel and their costs absorb 4% of post-tax incomes. Electric trucks would be 20-50% most costly, and hydrogen trucks would be 45-75% more, which…

Maintenance costs for gas-powered trucks?
Maintenance costs are tabulated by category, for a fleet of compressed natural gas (CNG) trucks, travelling 16M miles across the United States.

Costs of an LNG fuelling station
We have tabulated the costs of constructing an LNG-fuelling station across 55 cost lines, totalling €1M/site. c$10/mcf may be added to the cost of gas as a fuel.

Flaring reduction: screen of service and equipment companies?
This data-file is a screen of companies that can reduce routine flaring and reduce the ESG impacts of unavoidable residual flaring. The landscape is broad, ranging from large, listed and diversified oil service companies with $30bn market cap to small private analytics companies with
