New project will use AEM electrolysis in the production of zero-emission acetone

Curious what pathway they’re pairing with AEM here: green H2 to IPA then dehydrogenation, or a CO2-to-acetone route, and whether they plan to recover the O2 and stack waste heat to boost overall efficiency. Also, what H2 purity are they targeting (e.g., NH3/amine carryover control) and what’s the guaranteed stack life under intermittent loads, since downstream catalysts can be unforgiving.

At 0.5 MW you’re talking roughly 10 - 11 kg H2 per hour; how are they buffering that against renewable swings to keep a steady acetone spec, and is the O2 byproduct being used or just vented? More curious about AEM durability in the real world: CO2/carbonate management, chloride tolerance with non-18 MΩ-cm water, and expected stack replacement intervals.

AEM is attractive on capex, but how are you mitigating carbonate poisoning if the H2 feeds a CO2-to-acetone route - closed, CO2-scrubbed DI water and degassing on the loop, or something else? What’s the plan for load-following and buffer: can the 0.5 MW stack cycle daily without chewing membranes, and do you have enough H2 storage to keep the reactor from hunting? And please interlock H2/O2 dP, dew point, and LEL around the acetone area - well, there’s your problem if you don’t.
