Ethane cracking: the economics?
…intensity of ethylene production? Gas use (in mcf/ton) and electricity use (in kWh/ton) are captured in the model, and built up across pyrolysis, compression and separation. At $3/mcf gas and…
Is the world investing enough in energy?
Global energy investment in 2020-21 has been running 10% below the level needed on our roadmap to net zero. Under-investment is steepest for solar, wind and gas. Under-appreciated is that…
Global energy: supply-demand model?
…2030. (4) Pragmatic gas? Another means of re-balancing the global energy system is if global gas production rises at 2.5% per year, which is the number required, and that is…
Air conditioning: energy demand sensitivity?
…rule of thumb is that each 100 Fahrenheit variation will add 26 TWh of electricity demand, which equates to 200bcf of gas demand, or 0.6% upside in total US gas…
North Field: sharing the weight of the world?
…Our global energy balances, gas balances, and the ‘hole’ left by possible Russian gas supply disruptions are quantified on pages 2-4. Thus the Qatari North Field is now the most…
Crop production: what CO2 intensity?
…is N2O emissions, as c0.3-3.0% of all nitrogen fertilizers break down into N2O (per the IPCC). N2O is a greenhouse gas with 298x higher global warming potential than CO2, which…
How does CO2 increase global temperature?
…in the infra-red range. They span from 600 – 20,000 nm. But how much of that energy actually escapes into space? (2) Greenhouse Gases: CO2, CH4, N2O, et al. CO2…
Thermodynamics of CO2 at different temperatures and pressures?
…gas varies as a function of its temperature, compressibility, heat capacity ratio (Cp/Cv) and its molar mass. Our overview of thermodynamics explains how the efficiency of a gas-fired power cycle…
Flaring reduction: fire extinguishers?
…monetizing gas that is more than 20km from any existing infrastructure (page 8) and the other half of the challenge is in capturing small and hard-to-capture gas streams (page 9)….
CCS: amine degradation rates?
…precipitation and wet gas scrubbing. On the other hand, coal plants will burn off more oxygen, so there are lower oxygen concentrations in the flue gas, and less oxidative degradation….
