Hi all ! While I am finishing the article on PEM technology, please find another (shorter) article describing 3 key challenges related to the operation of electrolyzers in "offgrid mode", that is to say when the electrolyzer is powered by a dedicated with farm without complementary supply from the electric grid. - The operating range of the electrolyser (and why it is important for safety) - The frequency of electrolyzer set point change vs. REN supply variation - The cold/hot stand-by management strategy https://lnkd.in/ePgfB3iE Careful _ this list is not exhaustive as other challenges specific to offgrid projects exist, including on other blocks of the PtoX projects (Wind farm, derivative plant ...) As always, glad to have your feedback, comments, corrections ... Enjoy the reading ! #greenhydrogen #decarbonisation #renewables #offgrid #offgridsolar #hydrogen #runwayfbu #decarbonization #energytransition #hydrogene #offgrid

The Cost of Decarbonization (1/2) A short article jointly written with the friendly Aleix Marcó, summarizing where it makes sense to use green hydrogen in the energy transition. Green hydrogen makes sense in at least 3 very different scenarios: + When switching from a “carbon-based fuel” to electricity requires massive investments (e.g for batteries) + When the hydrogen molecule itself is needed as feedstock, e.g. for oil desulphurization in refineries or chemicals production (historical hydrogen application) + When electrification significantly increases the complexity of asset management https://lnkd.in/dcTewTA3 #decarbonization #greenhydrogen #heavyindustry #lcoh #lcoe

💡 Methanol is a promising low-cost hydrogen carrier given its high energy density, ease of transportation, and lower risk compared to ammonia. M2X Energy Inc. is dedicated in minimizing the cost and carbon intensity of the integrated process from crude methanol production, transporting methanol as low-cost carrier for hydrogen, then reforming methanol to hydrogen at point of use. One question that we are particularly interested in is if the energy intensive upgrading step can be bypassed for an electrochemical route to reform M2X's low-carbon methanol to hydrogen. To answer the question Chen Hsiang-Sheng (Johnson) is working towards understanding the associated energy penalties when crude methanol is used 'as-is' in electrolysis. This project is supported by FSEC® and M2X Energy Inc.. Read more here https://lnkd.in/esakUFGb #Hydrogen #Methanol #Sustainability #Innovation

First-ever industrial-scale AEM electrolysis stack demonstration successfully completed | Power to Hydrogen (P2H2) has partnered with global utility leaders American Electric Power (AEP), EDP, E.ON, and Electricity Supply Board (ESB) to demonstrate the first-ever industrial scale Anion Exchange Membrane (AEM)-based #electrolysis #stack for low-cost #greenhydrogen production. The pilot project focused on demonstrating a fully integrated system based on P2H2’s patented hybrid liquid alkaline/AEM stack design. During the successful Phase I of the project, the demonstrated pilot system used an AEM-based stack that was four times larger than has ever been installed with a customer to date. Phase II will demonstrate full-scale modules in a commercial setting. More specifically, the pilot project focused on demonstration of key performance criteria necessary for integrating the electrolysis system directly with #renewableenergy. The system demonstrated the ability to react quickly to load changes and produce #hydrogen more efficiently than any #renewable load-following product on the market. The system was operated under simulated renewable energy load cycles for over 1,000 hours of operation, with degradation rates matching conventional #alkaline and #PEM electrolysis systems. Renewable load following enables direct connection of the #electrolyzer to low-cost #electricity ‘behind the meter’ and will make the technology eligible for U.S. and European green hydrogen tax incentives. The demonstrated cost reductions with respect to electricity input and equipment cost are critical to reaching a <$2/kg hydrogen cost target, which can put clean hydrogen at a competitive level with fossil fuels, even without government incentives. The utility pilot took place at American Electric Power’s facility in Columbus, Ohio. With the successful completion of this pilot, the groups intend to test an even larger industrial-scale version of the technology by the end of 2024. Details of the next phase will be publicly announced in the near future. These pilots are focused on enabling a 10MW+ commercial-scale system that can make a significant impact on industrial and energy storage #decarbonization.

Systèmes de production d'énergies renouvelables et hydrogène vert
8moThanks, Loïc, for sharing this insightful article! It sparked my curiosity about the correlation between stack degradation and the frequency of start-ups, shut-downs, and setpoint changes in electrolysis systems. Exploring the intricate relationship between operational variables and stack health is fascinating. Any thoughts from the community on this?
