To protect the privacy and security of our attendees, we adhere to strict confidentiality policies. We do not share or sell our attendee list. Be aware of fraudulent companies claiming to sell or distribute the California Hydrogen Leadership Summit (CHLS) attendee list. Should anyone contact you about this, inform Show Management immediately at events@trccompanies.com.

Group discounts will be available after February 28. No code is required as the discount will automatically apply on the registration payment page in accordance with the highest number of registrants in the group. 

Group discounts cannot be applied retroactively to existing registrations, nor can individual registrations be combined to apply the group discount. Partial refunds cannot be issued should new attendees be added to the group after the initial group registration was submitted and processed for payment.

If you paid via credit card, you acknowledged and agreed that your 2025 California Hydrogen Leadership Summit (CHLS) registration charges will appear as TRC Environmental Corporation. If a dispute or denial of the charge occurs, and payment is not re-submitted, your registration(s) will be canceled, and registrant(s) will not be able to pick up their badge(s).

Registration refund requests must be submitted to registration@trccompanies.com. If your cancelation request is received by April 18, 2025, you will receive a refund, less a $100 processing fee for Industry/CHBC Member/Sponsor registrations and less $50 for Non-profit/Academic registrations. If approved, please allow up to four weeks for refund processing. After April 18, 2025, refunds will not be processed, however, substitutions are permitted until June 2, 2025. No substitutions will be allowed on-site. You will not be eligible for a refund if you are a “no-show.”

Badge sharing, splitting or duplicating made outside of the official CHLS registration system are strictly prohibited. Any registrant found in violation of this policy will have their badge confiscated, and they will be removed from CHLS immediately and forfeit attendance eligibility. All badge printing is done onsite in Sacramento. No badges are mailed to registrants prior to CHLS. All attendees must pick up their own badge; no one is permitted to pick up a badge on someone’s behalf. Attendees will be required to show a valid government-issued photo ID to pick up their badge.
