Energy Catalyst is Gold Open Access. There is an article processing charge of £150, raised only after acceptance and waived in full for WSSET members and for papers we invited, and no other charge at any stage.
This table lists every charge Energy Catalyst can make. There is no other fee, at any stage, under any circumstance.
Only after a paper has been accepted. Nothing is payable to submit, and nothing is payable if a paper is declined or withdrawn.
The editor who accepted your paper has no visibility of whether a charge was raised, waived or paid. Ability to pay plays no part in an editorial decision.
Every other cost of publishing, including editorial management, peer review, production, online hosting and long-term preservation, is met by Caravel Press.
Article processing charges are waived in full for members of the World Society of Sustainable Energy Technologies (WSSET), and for any paper we invited. The membership waiver has two steps.
A paper we invited carries no charge at all. Nothing has to be claimed: the invitation is on the record from the moment the paper is submitted, and the office applies the waiver.

Tell us when you submit
The submission form asks about fee status. Tick that one of the authors is a WSSET member, and give that author's name and the email address their membership is under. Nothing has to be uploaded or emailed. The editorial office confirms the membership with WSSET.
Authors who are not WSSET members, and whose paper we did not invite, may still ask for a waiver. Write to the editorial office at the journal's own address, when you submit or at any point before acceptance, and say briefly why.
Every request is considered individually by the editorial office and settled before review begins. It is decided independently of the assessment of the paper, and it has no bearing on whether a paper is accepted.
This policy applies to every journal we publish. Last revised 28 August 2026.
