Buyer beware

The ONLY official housing company for ACP CLEANPOWER 2021 is Orchid.Events. There may be other companies misrepresenting themselves as the official housing company for the show.

ACP does not sell its attendee list to third parties.  If you receive an email solicitation regarding the CLEANPOWER list, please do not respond as it may be a phishing exercise and is an inaccurate representation by the third party.


The Call for Proposals is now closed for both podium and poster presentations, but if you’d like to learn more about speaking at CLEANPOWER 2021, contact Satsuki Sokol.
