…endure supercriticality. https://thundersaidenergy.com/2023/02/09/co2-compression-stranger-things/ Energy density of hydrogen lags other fuels? The Density of Hydrogen is 0.08 kg/m3 at 20ºC and 1-bar of pressure, which is very low, mainly because of…
…sulphur compounds are easily treated. The process uses a hydrogen partial pressure of 10-30kg/cm2, 180-370C temperatures, and liquid:catalyst ratio up to 4:1. The catalyst contains Cobalt, Nickel and/or Molybdenum on…
This data-file models the costs of converting green hydrogen into ammonia, transporting the ammonia in an LPG tanker, then converting the ammonia back into hydrogen through ammonia cracking. $799.00 – Purchase Checkout…
Methanol is becoming more exciting than hydrogen as a clean fuel to help decarbonize transport. Specifically, blue methanol and bio-methanol are 65-75% less CO2-intensive than oil products, while they can…
…and CO, formed by reforming natural gas. But the higher the share of hydrogen, the lower the CO2, and thus there is opportunity to add merchant hydrogen to DRIs. Existing…
…electrolysers and fuel cells, underlying catalyst materials, membranes and their manufacturing. One patent seems like a breakthrough. Other patents candidly presented challenges for scaling up green hydrogen and raised questions…
…out as major hydrogen producers, each generating 250-300kTpa of H2. Which refiners make their own hydrogen versus purchasing merchant hydrogen How has the CO2 intensity of US refineries changed over…
This model captures the energy economics of gas pipelines, CO2 pipelines and hydrogen pipelines. Specifically, we have modelled energy requirements using simple fluid mechanics, and modelled capex costs using past…
…for green hydrogen, in order to ensure the hydrogen has minimal embedded CO2, and under new requirements from the US Inflation Reduction Act (page 4). Degradation of electrical equipment under…
…electrolyser, alkaline OH- ions diffuse. In a PEM electrolyser, protons, H+ ions, diffuse. Ten fundamental differences follow. The lowest cost green hydrogen will come from alkaline electrolysers run at high…
