Long-term modelling of energy systems with integration of demand response and power-to-X technologies - The INTERENERGY project: use of H2RES

The final conference of the project "Investigating energy transition pathways – interrelation between power-to-X, demand response and market coupling"– INTERENERGY , funded by the Croatian Science Foundation under the project number IP-2019-04 9482, will take place, as a side event of the SDEWES 2023 Conference, at 13:30, on Tuesday, September 26th 2023 in the ROOM A. The special event chair and project leader is prof. Neven Duić from the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture.

The INTERENERGY project deals with interrelation between different power-to-x and demand response technologies and market coupling in the energy transition. Role of these technologies is investigated from the context of market coupling, which is already underway in the European Union. The key research question is how to achieve the balanced integration of different power-to-X and demand response technologies, determine their optimal mix and avoid unnecessary technological lock-ins. In order to achieve this, new H2RES energy planning tool is being developed to model the behaviour of power-to-X and demand response technologies. On this event, participants will have the opportunity to get detailed information about the new, open source long-term energy planning model, which is developed with particular emphasis on the technologies that can enable energy transition towards 100% RES-based energy systems.

Also, a round table featuring the most prominent researchers in the field of energy planning will take place, with the hot topic of advances in energy system modelling, including the modelling of various e-fuels, energy conversions needed for balancing of the smart 100% RES-based systems and their management.

Smart Islands – Leading the energy transition: Experiences from H2020 INSULAE project

In the EU, 15 million people live on 2,400 inhabited islands, whose energy systems are usually small and isolated ecosystems. Some of the main challenges that these islands face are:

  • 3 to 4 times more expensive energy cost in islands than in the mainland
  • 2 to 3 times higher average carbon intensity than mainland
  • up to 10 times higher energy losses than the EU-28 average
  • on external supply, over 50% of power generation relied on fossil fuel import, which accounts for more than 10% of the islands’ GDP.

Scaling up renewables, energy efficiency, energy storage and clean transport are the key challenges that can lead to a more stable supply of clean and sustainable energy, as well as to an island energy self-sufficiency and security supply, while contributing to the fight against climate change.

INSULAE project fosters the deployment of innovative solutions for the EU islands decarbonization by developing and demonstrating at 3 Lighthouse Islands (located in Croatia, Denmark and Portugal) a set of interventions linked to 7 replicable Use Cases. INSULAE contributes to the Clean Energy for EU Islands Initiative by providing Action Plans for the islands to generate their own sustainable, low-cost energy.

The project team is carefully balanced along all the value chain counting five public authorities, six energy and water utilities, four technology providers, two energy software developers, six RTOs, one environment NGO, one business models expert, one engineering company and one entity for social aspects and replication.

 The Special Session „Smart Islands – Leading the energy transition“ at the 18th SDEWES Conference will bring together contributors of the INSULAE project disseminating the action plans and main outcomes. The results will be available for a wide replication plan and decarbonisation of EU islands.


Low-carbon society: an enhanced modelling tool for the transition to sustainability – hands on demonstration of the Wiliam model – LOCOMOTION project

With funding from the EU’s Horizon 2020 programme, the ‘Low-carbon society: an enhanced modelling tool for the transition to sustainability’ (LOCOMOTION) aims to design a new IAM (Integrated Assessment Model) to provide policymakers and relevant stakeholders with a reliable and practical modelling system to assess the feasibility, effectiveness, costs and ramifications of different sustainability policy options. By doing so, LOCOMOTION will help them to identify the most effective transition pathways towards a low-carbon society.

Building on existing IAMs developed by the EU-funded MEDEAS project, and including knowledge from other relevant models (World6, TIMES, LEAP, GCAM, C-Roads, etc.), a number of substantive improvements are planned with respect to the state-of-the-art in energy- economy-environment modelling. Drawing on research teams from different European countries, the improved IAM (Wiliam model) is the product of interdisciplinary work in data management, policy and scenario assessment, as well as the system dynamic modelling of relevant environmental, economic, social, technological and biophysical variables.

Development of an integrated solution for strategic long-term climate and energy policy planning and creation of joint climate and energy plans (KK. - Workshop on security of supply and vulnerability of the energy system

Trends in energy policy indicate the necessary changes in the system of planning and drafting of strategic documents and long-term energy and climate plans. Therefore, this project includes research and development of an integrated solution that consists of different modules, such as a module for optimizing energy generation and consumption, a module for energy system planning and monitoring its security and vulnerability, as well as models for simulating changes in energy production and consumption, for comprehensive drafting of long-term strategic energy and climate plans.
