Global gas: catch methane if you can?
…gas. If 3.5% of methane is leaked, then natural gas is, debatably, no greener than coal. Pages 5-8 quantify methane emissions and leaks across the global gas industry, including a…
Fast-charge the electric vehicles with gas?
…is spared the strain of sudden demand surges. Is upside suggested for gas? Utilisation of the fast-charging infrastructure is much more important to the overall economics than the gas price….
Gas-to-Power Project Economics
This data-file models the economics of constructing a new gas-to-power project, using simple or combined cycle gas turbines, based on technical papers and past projects around the industry. A dozen…
Gas industry CO2 per barrel?
…gas processing, LNG liquefaction, LNG tanker distances and pipeline distances. Energy return on energy invested is c20x across piped gas resources and c10x across LNG resources, compared with c7-10x for…
Methane Leaks from Downstream Gas Distribution
This data-file tabulates the methane emissions from downstream gas distribution across 160 US gas networks, which cover 1.1M miles of mains, 61M metered customers and >90% of the country’s retail…
Is gas a competitive truck-fuel?
…logistical. Based on real-world data, we think maintenance costs will be 20-100% higher for gas trucks (below). Gas-fired spark plugs need replacing every 60,000 miles. Re-fuelling LNG trucks requires extra…
Gas Gathering: how much CO2 and Methane?
Gas gathering and gas processing are 50% less CO2 intensive than oil refining. Nevertheless, these processes emitted 18kg of CO2e per boe in 2018, hence the gas industry must strive…
Methane emissions detract from natural gas?
This short model calculates the impact of methane emissions on the CO2/boe of burning natural gas, compared against coal. With methane emissions fully controlled, burning gas is c60% lower-CO2 than…
The World’s Great Gas Fields and Their CO2
The CO2 content of gas fields is going to matter increasingly, for future gas development decisions: CO2 must be lowered to 50ppm before gas can be liquefied, adding cost. Moreover,…
Production profiles: renewables vs oil and gas?
Wind, solar, oil and gas are all capable of supplying comparable energy at comparable prices: 5c/kWh wind and solar is economically competitive with c$50 oil and $6/mcf gas, over a…
