Gold hydrogen: the economics?
…at the surface. The best white hydrogen resources could cost $0.4/kg with a CO2 intensity below 0.4 kg/kg. This is materially better than today’s grey hydrogen from steam methane reforming….
Gas distribution: loss rates, leakage, unaccounted gas?
…of the natural gas that flows into downstream gas distribution networks may fail to be metered and monetized. This matters not just for avoiding methane leaks, but also should ideally…
Global energy market model for the energy transition?
…energy transition. Natural gas is the lowest carbon fossil fuel, with 54% of its combustion energy coming from hydrogen in the methane molecule (CH4). Hence gas ramps by 2.2x to…
Decarbonize shipping: alternative fuel costs?
…a gas-fired marine engine suffers from methane slip. Blue methanol, blue ammonia and renewable diesel are next most economical, but add 0.4 – 0.7% to the final costs of shipped…
Energy transition: distorted by politics?
…is despite many OPEC countries – Iraq, Nigeria, Venezuela – having much higher levels of flaring, methane leaks and CO2 emissions than US producers (data below). https://thundersaidenergy.com/downloads/oil-industry-co2-per-barrel/ (3) Another of…
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…
Deep blue: cracking the code of carbon capture?
…12. Different blue hydrogen reactor designs are discussed, and their economics are modelled on pages 13-15. Autothermal reforming should take precedence over steam methane reforming as part of the energy…
US gas transmission: by company and by pipeline?
…reported compressor stations to each pipeline (80% of the energy use and CO2e come from compressors), to plot the total CO2 intensity and methane leakage rate, line by line (see…
Bio-engineer plants to absorb more CO2?
…developed a strain of rice that emits less methane, as it contains a gene from barley, reducing the carbon that the plant moves underground, which in turn reduces the carbon…
Energy economics: energy content of combustion fuels?
…of which c54% derives from hydrogen in CH4 forming water vapor, and c46% derives from the carbon in CH4 forming CO2. Thus methane has an energy content of 304kWh/mcf and…
