Michael E. Webber (professor of energy resources at Austin University, Texas) says on page 30 in the April 2021 edition of Scientific American that “Because of hydrogen’s low density it takes a lot of energy to move it through a pipe compared to denser gasses like methane... After several hundred kilometres the inefficiency makes moving hydrogen more expensive than the value of the energy it carries.” Is that right? Nobody in the presentations here actually had a graph of energy-in versus energy-out in terms of pipeline length. We had the comparison of speeds of energy transmission, but not transmission cost. Is the professor right, and if so where are the distance limits after which it becomes uneconomic? I'm not a professional, just an interested spectator.
Hi, How do you mitigate the long-term effect of hydrogen brittleness and corrosion on existing Steel Natural Gas pipes? ıf you can share some Research or mitigation efforts it would be a game changer. In Turkey there's trials of %5 to %15 mixture of H2 to NG but I doubt it will be a very expensive experiment when the whole country's interconnected pipeline starts to leak in the near future.
On the 8 of June we will host a webinar on materials and hydrogen: forcetechnology.com/en/events/2021/webinar-materials-compability-in-hydrogen-environments
I have seen glass coating and water help preventing hydrogen brittleness and corrosion. Why can't we store solar energy into gravity first, and then use the gravity to get electricity for electrolysis?!! Please don't forget that Water are themselves the Hydrogen rich carriers already; of course, there are CH4 and NH3 carriers as well, so we should stop being blinded by the CCP-infiltrated global-govt, OK !!!
@@bindiberry6280 You don't need gravity storage it will waste energy during conversion. Excess solar energy can be directly send to electrolysis. Eventually all excess energy will topple to short term batterry storage and when they top up, will spill over to hydrogen generation. Just wait until renewable capacity to catch up the demand. 2032 max.
Hi Keith. We have tested the Danish grid: forcetechnology.com/en/cases/hydrogen-transport-danish-gas-pipelines-ideal and have made a report: www.dgc.dk/sites/default/files/filer/publikationer/R1003_hydrogen_gas_grid.pdf
Hi Tahir. It is not a course but you are most welcome to watch the webinar and if interested join the LinkedIn group: www.linkedin.com/groups/12493589/
It was an interesting sessions, thanks to all speakers and the coordinator.
Very Excllent presentation gaidance information Thank.

Congratulation madam.
Thank you for sharing.

Has HDPE been tested for low pressure hydrogen transportation?
Hi Keith. We have tested the Danish grid: forcetechnology.com/en/cases/hydrogen-transport-danish-gas-pipelines-ideal and have made a report: www.dgc.dk/sites/default/files/filer/publikationer/R1003_hydrogen_gas_grid.pdf
57:30 pipeline engineering discussion starts
Thanks
Very informative
I m from India and I m interested in course, Can I get educational Visa ?
Hi Tahir. It is not a course but you are most welcome to watch the webinar and if interested join the LinkedIn group: www.linkedin.com/groups/12493589/
What LinkedIn page and speaker email ?
