Gas dehydration: costs and economics?
Gas dehydration costs might run to $0.02/mcf, with an energy penalty of 0.03%, to remove around 90% of the water from a wellhead gas stream using a TEG absorption unit, and satisfy downstream requirements for 4-7lb/mmcf maximum water content. This data-file captures the economics of gas dehydration, to earn a 10% IRR off $25,000/mmcfd capex.

Japan gas and power: supply-demand model?
Japan’s gas and power markets are broken down by end use, traced back to 1990, and forecast forwards to 2030 in this model. Japan’s electricity demand now grows at 0.3% pa. Ramping renewables, nuclear and gas back-ups could halve Japan’s total grid CO2 intensity to below 0.25 kg/kWh by 2030.

Load bearing: will solar+gas be cheaper than gas alone?
The costs to power a real-world load – e.g., a data center – with solar+gas will very often be more expensive than via a standalone gas CCGT in the US today. But not internationally? Or in the future? This 9-page note shows how solar deflation and load shifting can boost solar to >40% of future…

The World’s Great Gas Fields and Their CO2
This data-file tabulates 30 major gas resources around the world, their volumes, their CO2 content and how the CO2 is handled. This matters because higher CO2 gas fields are more costly to develop into LNG, while CO2 venting is no longer acceptable without CCS. Permian & Marcellus LNG are best positioned.

Gas power generation across five-minute intervals?
Power generation data are aggregated for ten of the largest CCGTs and gas peaker plants in Australia, across five-minute intervals, May-2024 and May-2014. This makes for a fascinating case study into how gas turbines are used to stabilize power grids, backstop renewables, and how this has changed over time.

Reciprocating gas engines: levelized costs?
The economics costs of reciprocating gas engines are captured in this data-file. As a rule of thumb, a 5MW recip that costs $1,500/kW, runs with 60% utilization, and 40% efficiency, requires a 8-10c/kWh power price (or levelized cost) to generate a 10% IRR, depending on the CO2 price. Capex costs are derived from prior case…

Leading Companies in Pipeline Gas Technology?
This data-file tracks 800 patents innovating pipeline transportation of natural gas, to screen for exciting technologies and companies. 6 publicly listed firms and 6 venture-stage start-ups stood out from the analysis, commercialising next-generation materials, monitoring methods and optimizing gas distribution.

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.

Gas power: does low utilization entail spare capacity?
The US has >400GW of large gas-fired power plants running at 40% average annual utilization. Could they help power new loads, e.g., 60GW of AI data-centers by 2030? This 5-page note shows why low utilization does not entail spare capacity, and in turn, estimates the true spare capacity for loads such as data-centers.

Gas peaker plants: the economics?
Gas peaker plants run at low utilizations of 2-20%, during times of peak demand in power grids. A typical peaker costing $950/kW and running at 10% utilization has a levelized cost of electricity around 20c/kWh, to generate a 10% IRR with 0.5 kg/kWh of CO2 intensity. This data-file shows the economic sensitivities to volatility and…
