Most of the work of the IHFC is performed by its working groups. These are organized by one or a group of speakers. Members and speakers of these working groups need not necessarily be members of the IHFC. Please do not hesitate to contact the speakers in case of questions or suggestions.
The current working groups and their speakers are:

- Workshop on heat flow in Africa, South America and South Atlantic Ocean (2 days, July 2023)
- New quality scheme published (July 2023)
- Database release 2023 (January 2023)
- Workshop on in-depth evaluation, development and discussion of criteria for determination, documentation, data-banking, and quality assessment of heat-ﬂow data during the Cermak7 (7th International Meeting on Heat Flow and the Geothermal Field Potsdam), Germany, 20.06.-22.06.2022
- Collaborative development of a new quality scheme for the global heat flow database database.

The working group « Marine heat flow »is new since 2023. The primary focus is to identify the scientific problems that can be addressed by the acquisition of shallow sub-seafloor thermal gradients and thermal conductivity data, collectively used to quantify conductive heat flow. However, the group will address the full scope of problems and techniques in data acquisition as well as the nuances in understanding the processes that involve the quantification of energy and fluid fluxes, again requiring knowledge of the thermal state deduced from observations that include heat flow, sub-bottom temperature, and thermophysical rock and fluid properties. The renaissance of interest in marine heat flow mirrors the shift to multidisciplinary approaches to science problems in the wider community, such as the recent focus on using heat transport as a tracer of other processes. We identified three major questions the marine working group should focus on:
- What are the fundamental science questions to be addressed using marine heat flow data (among other information and methods) in the next decades?
- Which technical capabilities will be required to address these questions, and how can these capabilities be developed and sustained to assure access to critical instrumentation at reasonable cost?
- Can Heat Flow become an ocean variable in the short term? How important is heat flow as one of the ocean variables crucial for understanding and monitoring various aspects of the Earth's climate system, weather patterns, marine ecosystems, and natural resource management?
The working group aims to encourage discussion and strengthen communication in the marine heat flow community sub group. This includes Identifying all actors of the marine heat flow community (scientists, engineers, companies) and motivating an active participation in the IHFC activities (meetings, summer schools, data review).

The Applied Geothermics working group delivers guidelines, recommendations and training for the application of heat flow concepts and practices to the exploration, characterization, and production of earth resources. It serves as a point of contact and communication between the IHFC and individuals and groups from various resource sectors.
Speaker: Florian Neumann
The working group "Education and Dissemination" is developing heatflow.X, a program framework to create and bundle a number of IHFC science and outreach activities related to heat-flow research. The program aims at developing organizational structures, specific methods, and tools to effectively support the heat-flow community with transferable knowledge.
