Thermal power plant: loss attribution?
…a combined cycle gas turbine (chart below). Here is hoping that this simple model of gas turbine efficiency is useful. Intriguingly, we think that the energy penalties for gas-fired CCS…
US decarbonization: energy and CO2 emissions?
…Gas demand falls 25% from 90bcfd in 2022 to 66bcfd in 2050 (global gas model here). Switching coal to gas saves 50-60% of the CO2 for the same amount of…
Shell drives LNG in transport?
…run on LNG, which can reach $17-35M for the largest tankers. Gas Weathering is another challenge, less well-known, but crucially important. LNG is a mixture of hydrocarbon gases, all with…
The Ascent of LNG?
…of this coal power to gas by 2030. Converting it to decarbonised gas could save c1bn tons of CO2 emissions per annum. In turn, this could be achieved by 200GW…
The green hydrogen economy: a summary?
…hydrogen was produced globally. 95% of it was grey, meaning it was derived from steam-methane reforming of natural gas. The cost of this process is around $1.3/kg ($11.5/mcf-gas– equivalent) and…
LNG: top conclusions in the energy transition?
…disruptions. Meanwhile, Europe’s 15bcfd of Russian gas imports, volumetrically equivalent to 110MTpa of LNG, are shifting. The best note covering our gas outlook is linked here and our European gas…
Methane emissions from pneumatic devices: by operator, by basin?
…actuated by pressurized natural gas, widely used in the oil and gas industry, and numbering around 800,000 in the US in 2021, across 22Mboed of production that we are tracking,…
Decarbonize Heat?
…including heat pumps, renewables, biogas and hydrogen. The lowest cost and most practical solution is to double down on natural gas, alongside nature-based carbon offsets. Global gas demand for heating…
CO2 concentrations in industrial exhaust streams?
…gas boiler or burner will have 4% CO2 in its exhaust gas, rising to 8-12% with exhaust gas recirculation, and rising further, to 10-12% at a typical coal fired power…
Switching gears: the most potent GHG in the world?
…(below). https://thundersaidenergy.com/downloads/wind-and-solar-capacity-additions/ https://thundersaidenergy.com/2021/02/18/industrial-heat-the-myth-of-electrify-everything/ A read-across for gas? There are people out there who look at natural gas’s global warming potential — 80-100x CO2 on an instantaneous basis, 21-25x CO2 over…
