Franz Geiger at Northwestern U @northwesternu quantified the excess energy cost with flipping water before splitting it - #electrolysis.
Hematite #OER electrodes were studied; maybe conventional iridium in the future?

Unfortunately, LOHC in general, and Ayrton specifically, are not the magic answer for hydrogen storage & transport.
1)Their 55g/L 𝗴𝗿𝗼𝘀𝘀↙️ gravimetric H2 storage capacity is not much better than alane's 𝗻𝗲𝘁 capacity↘️ in this 2012 @argonne figure, which also accounts for tankage & BOP.
2) Ayrton's WIPO app ↘️ ↘️ WO2024119281A1 includes NO data, NO LOHC composition, and is pretty useless.

And here's some info on underground #hydrogen storage history & R&D:
🌟Underground hydrogen storage has/is operating in salt domes AND aquifers AND depleted gas reservoirs (pores). https://bit.ly/3EMaK2u
🌟Vallourec has metal tubes for 1-100T #H2.
🌟#HYBRIT is testing lined rock caverns for hydrogen.
#Hydrogen101
Fun fact #1: Underground hydrogen #H2 storage is just as safe & easy to use as underground natural gas storage, & uses the same tech
Fun fact #2: Underground natgas provides 144x the combined output from all currently-existing battery & pumped hydro energy storage facilities in the USA
↙️ Michael Faust/Velocity Strategies need to keep up with the hydrogen ecosystem.
Sierra Northern didn't test the FIRST 4-axle hydrogen fuel cell electric switching locomotive. Just first in California.

@bair 2021 berichtete bereits Cicero (Ja ,die…) Aber das Thema stoffliche Abkehr von fossilen Molekülen ist ein risieges Problem . Ganz ohne Düngemittel wird es schwer mit einer kompletten Umstellung der Landwirtschaft. Wir benötigen eine klimaneutrale Kohlenstoffquelle , Energie alleine ist leider kein Ersatz. Deshalb setze ich mich immer wieder für #Biogas als brückenbaustein für die notwendigen Prozesse ein. Biogas liefert Moleküle , guter Speicher vielfältiger nutzbar als Wasserstoff. #h2 #solar #wind #ee #pv

Estonia’s @Elcogen_EU claims reversible solid oxide fuel cell #SOFC - electrolyzer #SOEC hydrogen tech
IMO Elcogen's EU-backed systems aren't practical, as 333 of their tiny 3.3kW stacks are needed for a 1 MW-scale #fuelcell pilot.
Think of the multiple failure points!
Think of maintaining all those blowers and other moving parts!

Hey #NYSERDA,↙️ you say nothing (beyond batteries) about other important zero emission land vehicles #ZEV: hydrogen fuel cell electric cars #FCEV, buses #FCEB, and trucks #FCET!
And this presser totally ignores last week's NY State Hydrogen Assessment↘️, which also covered air, marine & rail transport!

Die Firma, die den Leuten für min. 60.000 € saisonale Wasserstoffgeräte mit Brennstoffzelle in den Keller gestellt hat, ist pleite.
Die Geräte müssen auch vom Hersteller gewartet werden um im Betrieb zu bleiben.
Japan gets closer to making pink hydrogen with a 30MWth high-temperature gas-cooled nuclear test reactor #HTGR feeding 950C heat to thermochemical sulfur-iodine #hydrogen cycle.
After making carbon-free hydrogen, remaining heat will be used in a bottoming cycle for electricity production, water desalination, and district heating.

#NYSERDA 2025Apr22 Report: New York State Hydrogen Assessment.
⭐#hydrogen demand could reach 1.1MM tonne/yr by 2050, 11.4% of the State’s total energy market
⭐#H2 costs:🥇production,🥈storage,🥉distribution
COMMENT 1
Small modular reactor #SMR is used throughout the Report, then the Conclusions rename them "modalized nuclear plants"
COMMENT 2
Puts alkaline exchange membrane #AEM in the same class as liquid alkaline electrolyzers #LAE
⚡💧🏝️ How can #H2 help build a 100 % renewable #energy supply on #islands in South East #asia? Our experts from the Green-H2Islands project are investigating on the Thai island of Koh Jik how the integration of hydrogen technologies into an existing renewable energy system can make the island a model for the region.🌏
The German-Thai Chamber of Commerce has now published a summary of the project launch in its magazine:
MIT ChemEng first author Shaylin Cetegen with Barton/MIT & Gundersen/NTNU:
Liquid air energy storage #LAES levelized cost of storage #LCOS for long-duration energy storage: ⅓ cost of lithium-ion batteries & ½ pumped hydro.
#LDES of 1day/1wk/1month, but not seasonal storage.
IMO looks like hydrogen still wins for seasonal storage.
