…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…
What degradation rate is expected for a green hydrogen electrolyser, if it is powered by volatile wind and solar inputs? This 15-page note reviews past projects and technical papers. 5-10%…
This 16-page note models the green hydrogen value chain: harnessing renewable energy, electrolysing water, storing the hydrogen, then generating usable power in a fuel cell. Today’s end costs are very…
This data-file derives some conclusions into the evolving landscape of green hydrogen electrolysers in Europe, based on a list of c240 distinct projects, looking project-by-project, country-by-country. The market is shifting…
The best opportunities for hydrogen in the energy transition will be to decarbonize gas at source via blue and turquoise hydrogen, displacing ‘black hydrogen’ that currently comes from coal, and…
Steel explains almost c10% of global CO2. Hence 2021 has seen the world’s first ‘green steel’ made using green hydrogen. Yet inflation worries us. At $7.5/kg H2, green steel would…
…hydrogen conversion and selectivity). Our estimates into hydrogen consumption of hydrogen peroxide production are tabulated in the data-file. The CO2 intensity of hydrogen peroxide production is 3 tons/ton, as our…
…https://thundersaidenergy.com/downloads/co2-emissions-from-batteries-when-do-evs-break-even/ Green hydrogen: what implications? The blending of RECs with green hydrogen could become a minefield of complexity. For example, imagine a hydrogen electrolyser that is powered by a wind…
…CO2 must be disposed of by the midstream industry? For green hydrogen, how much electricity will be used to produce green hydrogen, and other e-fuels, by region, and over time?…
…Use of green hydrogen in transport still remains very small, across several thousand vehicles (i.e., not several million). One thing that would improve our outlook on green hydrogen might be to see its…
