Data for: "International database of hot sedimentary aquifer geothermal projects: De-risking future projects by identifying key success and failure criteria"

Background:
Hot sedimentary aquifers (HSAs) have huge potential for low-carbon energy supply but remain a relatively untapped resource. The main technical barriers to HSA deployment are subsurface risks, associated well design and completion requirements, and financial constraints.

Aim:
This study aims to identify key gaps and parameters responsible for the failure of HSAs projects, and provide recommendations to geothermal stakeholders.

Data collection methodology:
Data were collated using a systematic literature review approach following the PRISMA standards.

Dataset structure:
57 components of HSAs projects in Australia, Croatia, Denmark, France, Germany, Poland, the Netherlands, and the UK were extracted. Collated data especially include technical information on the project and the boreholes, geology and hydrogeology parameters, and the risks associated with each project.
