The main energy carriers that will lead the energy transition are electricity and decarbonised gases, in particular green hydrogen. In the energy system of the future, the decarbonisation of industrial cooling/heating processes, the central role of hydrogen, the activation of demand and the coordination of the different energy vectors and markets through efficient economic signals will be key aspects. This necessary transformation of the economy in general and the energy sector in particular poses innumerable challenges. In this context, it will be essential to have tools to evaluate strategies that allow the Spanish economy to be relevant in the European decarbonization process.

In order to provide solutions to the current challenges and constraints, the aim of the ONESYSTEM project is to research and develop tools for the integration of energy carriers that allow the exploitation of synergies between them to improve the efficiency of energy supply and minimise the cost of decarbonising the economy. These tools are of two types: modelling tools and regulatory tools. The former are based on the development of techno-economic analyses, which are essential in a context of unparalleled technological and economic uncertainty. The latter, crucial in a sector in which public-private coordination is essential, are focused on the design of the regulatory framework necessary for the appropriate development of new business models. This project aims to develop models for analysing possible future routes for the integration of energy systems, focusing on Spain and its interaction with the rest of Europe. As part of the project, it will also seek to ensure that the tools developed can be replicated in other European markets.

Layman's summary: The ONESYSTEM project develops regulatory and modelling tools to enable efficient integration of the energy carriers that will characterise the energy sector of the future (electricity and decarbonised gases, such as green hydrogen).
