GHGT-18 Call for Abstracts

The call for abstracts for GHGT-18 is now open.

The GHGT-18 Call for Abstracts will close in

Conference organisers invite submissions of abstracts for consideration for both oral and e-poster presentations. All abstracts should align with the technical themes of the conference and include detailed information to facilitate fair assessment. Abstracts must clearly and accurately represent the content of the paper proposed to be presented at GHGT-18 and must have the permission of all co-authors or parties before submitting.

Special attention will be given to the presentation of results and new developments in CCS, CCUS, and other clean energy technologies and opportunities.

By submitting an abstract, if accepted, at least one author is expected to register, attend, and participate in person at GHGT-18. All presenters will be required to pay the registration fee. To ensure their work can be presented they or a co-author(s) must complete their registration for GHGT-18 ideally by June 2026 (before early-bird registrations end) when the online agenda will be published.

All presented work (oral and e-poster) will be expected to produce a paper to be submitted to SSRN following the conference proceedings.

Abstract Format & Submission Process

Abstracts should be between 500 and 1000 words, on the conference template, in English, and contain the paper title, author(s) name(s) and organisation(s). Abstracts submitted below or above this word limit may not be accepted for review.

When submitting work it is important to remember that, if selected, the online agenda will always show the submitting author as the presenter of the work, so if you are planning to submit multiple abstracts, and intend that a different co-authors will present, then those abstracts should be submitted by the intended presenter, otherwise your name will show as presenter against all the work you submit.

It is also important to ensure you select both the main theme and the sub-theme, if you are unsure your work fits under one of the sub-themes listed you should choose ‘other / no sub theme’ from the list to ensure it is seen by the correct reviewer.

Deadline

Abstract submission will open in September 2025. Abstracts must be submitted through the abstract portal by January 19, 2026. Abstracts must use the template and no further abstracts will be accepted after this deadline.

Presentations

When submitting you will see two options of either Oral or E-poster, you can select your preference but be aware that the TPC will make the final decisions on which abstracts would fit best in the oral technical sessions and which would be better suited to an e-poster presentations.

Oral Presentations

An oral presentation is given in person (not virtual) in PPT format using your own organisations template and is set at 20 minutes, 5 minutes of which will be a Q&A facilitated by the session chair. The PPT is not published by the conference and not shared with anyone other than the audience in the room for that session. A full paper of the work is required so that this can be published as part of the conference proceedings after the conference has taken place as we only publish presented work.

Key benefits:
• Work credited and included in online and printed programme
• Oral presentation in a parallel technical session
• Paper published via SSRN following the conference (paid for by the conference)

E-Poster Presentations

The E-posters are multimedia quick-fire presentations and improve upon the previous e-poster sessions from GHGT-16 & 17 based on feedback received. A multimedia quick-fire presentation is a short, fast-paced talk, typically 3-5 minutes, that uses various media elements like text, images, graphics, audio, and video to provide a concise overview of a topic. All work is presented in person (not virtual) and will be managed by specialist provider Kubify. All training, support and tools are provided by Kubify before, during and post conference. Kubify will also create a mini version of the work, featuring a QR code that delegates can scan to access the full presentation, helping them plan their schedules and engage during the assigned e-poster session. Conference delegates can also access the presentations at any time, via the Kubify showcase website, to explore the interactive content and engage with the authors and other delegates. This can include posting comments and questions in the chat area.

Key benefits:
• Multiple opportunities to share your work (before, during and post conference)
• A captive audience at your e-poster enabling you to easily follow up and connect after
• Work referenced in the conference proceedings
• Paper published via SSRN following the conference (paid for by the conference)
• Content available via the Kubify website for at least 6 months post conference
