Model prilagodbe naftne i plinske infrastrukture sukladno niskougljičnom razvoju energetskog sektora (MINES)
Funding source: Next Generation NPOO project, funded by the European Union
Duration of the project: 01.10.2025 - 30.09.2029
Project leader: Prof. dr. sc. Daria Karasalihović Sedlar
Total amount of project funding: EUR 35.965,98
Project summary:
The project envisages the development of a model for the adaptation of the existing oil and gas infrastructure through three main research segments. The first segment includes the evaluation of risk parameters in the techno-economic assessment of geothermal potential using data from existing oil and gas wells. The second segment refers to the exploitation of the existing gas infrastructure and the development of a regulatory framework with the aim of increasing the share of biomethane in the energy sector. The third segment includes the development of guidelines for the integration of hydrogen into existing natural gas systems and the harmonization of legislation in the Republic of Croatia with European guidelines. The development of guidelines for the exploitation of the existing infrastructure specified in the project contributes to the transition to a circular economy, climate change mitigation and pollution prevention and control.
Project objective
Energy transition is a key feature of the modern energy sector with a special emphasis on sustainability. Although the term sustainability in the energy context is most often associated with environmental aspects, energy transition requires a broader understanding of sustainability. In addition to environmental sustainability, the goal of energy transition is to achieve technical sustainability through the use and development of efficient technology, social sustainability in terms of fair access to resources, and economic sustainability through efficient management of costs and investments. The synergy of all the above forms of sustainability, driven by the energy transition, represents the conceptual framework of this project. In accordance with the above, the idea of this project is based on the assumption that the existing oil and gas infrastructure, given its wide distribution and technological maturity, can be effectively and cost-effectively repurposed for the integration of renewable energy sources. Given the already existing facilities and resources, the repurposing process reduces the need for new investments in the construction of completely new energy systems, thereby reducing the costs and timeframe for the implementation of new forms of energy. Such an approach contributes to reducing the negative impact on the environment, as it reduces the amount of waste and emissions associated with the construction of new, but also the dismantling of old infrastructure. By integrating technical, economic and environmental sustainability, the project aims to create a model of a sustainable energy system that combines the positive and beneficial aspects of fossil and renewable energy, thus creating a long-term sustainable solution that meets the environmental goals of reducing emissions, as well as the economic requirements of sustainability and profitability. The main objective of the project is to develop guidelines for adapting the existing oil and gas infrastructure to integrate renewable energy sources and renewable gases and promote a sustainable energy system. The project supports the strengthening of the circular economy through two main aspects:
- Reducing energy losses - energy storage
- Sustainability of resources - revitalization of existing infrastructure
The model for adapting the existing fossil fuel infrastructure will focus on geothermal energy, biomethane and hydrogen for the purpose of mitigating climate change. An additional objective of the project is to establish guidelines for the further development of a strategic and regulatory framework for the implementation of renewable energy sources in the existing energy system.
Project methodology:
- In the initial phase, all data relevant to the project will be collected. In the analytical phase, graduate students will be involved in the project, primarily for the purpose of data collection and market analysis. The emphasis of this part will be on:
- Analysis of regulatory frameworks for gas networks - standard quality of natural gas.
- Market analysis and identification of potential infrastructure for hydrogen and biomethane and technical requirements for their transport and storage.
- Analysis of techno-economic aspects of geothermal projects:
- Analysis of risk parameters for techno-economic risks of geothermal projects.
- After the initial analytical phase, a technical evaluation will be carried out. As part of the technical evaluation, doctoral students will also be involved in the projects. The following is planned:
- As for renewable gases, the composition of biomethane and natural gas will be compared, with the aim of identifying problematic components and potential obstacles to transport and storage in the existing gas system according to the European gas quality guidelines.
- After analysing the market potential of hydrogen and the regulatory requirements for its implementation through blending.
- Proposal for a regulatory framework
- Proposal for a regulatory framework for biomethane and hydrogen in view of the European gas quality guidelines.
Expected project results:
- Evaluation of risk parameters in the techno-economic assessment of geothermal potential.
- Identification of critical parameters of biomethane composition for the underground gas storage system.
- Determination of the impact of hydrogen blending on individual parts of the gas system.
- Development of guidelines for the integration of biomethane into existing natural gas systems and harmonization of legislation in the Republic of Croatia with European guidelines.
- Development of guidelines for the integration of hydrogen into existing natural gas systems and harmonization of legislation in the Republic of Croatia with European guidelines.
