The SuperP2G project, led by Dr. Martin Pumpa of the Logical Institute gGmbH in Freiberg, ran from 1 November 2019 to 31 March 2023 and was financed under the European Union’s Horizon 2020 programme. Its core aim was to lower the barrier for validating and deploying Power‑to‑Gas (P2G) technologies for stakeholders in smart energy systems, sector coupling, and local and regional development. By linking five national initiatives across Europe, the consortium fostered an open exchange of knowledge and jointly addressed the specific challenges each partner faced.
On the technical side, the project produced three major tools that build on and extend existing software. The DBI‑MAT tool was created by converting the MATLAB code of the H₂‑Index II into Python and restructuring it for independent operation. It serves as a microgrid analysis platform that incorporates load‑dependent electrolyzer efficiency curves for both proton‑exchange‑membrane (PEM) and alkaline electrolyzers, enabling detailed optimisation of system parameters. The H₂‑Index III, a regional potential assessment tool, was developed to quantify renewable gas prospects across different European regions, providing stakeholders with data‑driven insights into market conditions and regulatory frameworks. Finally, the SuperP2G Toolbox was built as a public web‑based application that integrates the source code of OptiFlow and the newly developed H₂‑Index II. Its interface, styled after scientific poster formats, offers “focus pages” that guide users through the evaluation of P2G scenarios, from technology selection to economic assessment.
Performance evaluation of the tools demonstrated that the DBI‑MAT platform can simulate complex multi‑sector energy networks with high fidelity, while the H₂‑Index III delivers region‑specific renewable gas potentials that align with current EU market data. The SuperP2G Toolbox, now available online, has been tested in a case study for the Apulia region, showing that the combined use of the three tools can reduce the time required for feasibility studies by up to 40 % compared with traditional methods. These results confirm that the project’s objectives of improving existing tools, making them open access, and creating a new public tool were met.
Collaboration was central to the project’s success. The consortium comprised partners from Germany (DBI, ERIG), Denmark (DTU), Italy, and other European nations. DBI coordinated the knowledge‑exchange activities, organising workshops that brought together experts from all partners to discuss methodologies and share preliminary findings. DTU contributed advanced modelling capabilities, while ERIG supplied data on energy markets and stakeholder perspectives through surveys and policy analysis. The project also integrated with ERA‑Net, participating in discussion forums and joint document preparation to shape policy recommendations. Communication and dissemination were handled through workshops, webinars, and a dedicated website (https://superp2g.external.dbi‑gruppe.de/), ensuring that results reached a broad audience of policymakers, industry representatives, and researchers.
In summary, SuperP2G delivered a suite of validated, open‑source tools that enhance the planning and operation of P2G systems across Europe. By combining technical innovation with robust stakeholder engagement, the project has advanced the readiness of P2G technologies for real‑world deployment and provided a scalable framework for future research and policy development.
