Description of programme
"Horizon Europe - Cluster 5 - Destination 3: Sustainable, secure and competitive energy supply"

This Destination includes activities targeting a sustainable, secure and competitive energy supply. In line with the scope of cluster 5, this includes activities in the areas of renewable energy; energy system, grids and storage; as well as Carbon Capture, Utilization and Storage (CCUS).

The transition of the energy system will rely on reducing the overall energy demand and making the energy supply side climate neutral. R&I actions will help to make the energy supply side cleaner, more secure, and competitive by boosting cost performance and reliability of a broad portfolio of renewable energy solutions, in line with societal needs and preferences. Furthermore, R&I activities will underpin the modernisation of the energy networks to support energy system integration, including the progressive electrification of demand side sectors (buildings, mobility, industry) and integration of other climate neutral, renewable energy carriers, such as clean hydrogen. Innovative energy storage solutions (including chemical, mechanical, electrical and thermal storage) are a key element of such energy system and R&I actions will advance their technological readiness for industrial-scale and domestic applications. Carbon Capture, Utilisation and Storage (CCUS) is a CO2 emission abatement option that holds great potential and R&I actions will accelerate the development of CCUS in electricity generation and industry applications.

This Destination contributes to the following Strategic Plan’s Key Strategic Orientations (KSO):

  • C: Making Europe the first digitally enabled circular, climate-neutral and sustainable economy through the transformation of its mobility, energy, construction and production systems;
  • A: Promoting an open strategic autonomy[[‘Open strategic autonomy’ refers to the term ‘strategic autonomy while preserving an open economy’, as reflected in the conclusions of the European Council 1 – 2 October 2020.]] by leading the development of key digital, enabling and emerging technologies, sectors and value chains to accelerate and steer the digital and green transitions through human-centred technologies and innovations;

It covers the following impact areas:

  • Industrial leadership in key and emerging technologies that work for people;
  • Affordable and clean energy.

The expected impact, in line with the Strategic Plan, is to contribute to “More efficient, clean, sustainable, secure and competitive energy supply through new solutions for smart grids and energy systems based on more performant renewable energy solutions”, notably through

  1. Fostering European global leadership in affordable, secure and sustainable renewable energy technologies and services by improving their competitiveness in global value chains and their position in growth markets, notably through the diversification of the renewable services and technology portfolio (more detailed information below).
  2. Ensuring cost-effective uninterrupted and affordable supply of energy to households and industries in a scenario of high penetration of variable renewables and other new low carbon energy supply. This includes more efficient approaches to managing smart and cyber-secure energy grids and optimisation the interaction between producers, consumers, networks, infrastructures and vectors (more detailed information below).
  3. Accelerating the development of Carbon Capture, Use and Storage (CCUS) as a CO2 emission mitigation option in electricity generation and industry applications (including also conversion of CO2 to products) (more detailed information below).

Fostering the European global leadership in affordable, secure and sustainable renewable energy technologies

Renewable energy technologies provide major opportunities to replace or substitute carbon from fossil origin in the power sector and in other economic sectors such as heating/cooling, transportation, agriculture and industry. Their large scale and decentralised deployment is expected to create more jobs than the fossil fuel equivalent. Renewable energy technologies are the baseline on which to build a sustainable European and global climate-neutral future. A strong global European leadership in renewable energy technologies, coupled with circularity and sustainability, will pave the way to increase energy security and reliability.

It is imperative to enhance affordability, security, sustainability and efficiency for more established renewable energy technologies (such as wind energy, photovoltaics or bioenergy), and to further diversify the technology portfolio. Furthermore, advanced renewable fuels, including synthetic and sustainable advanced biofuels, are also needed to provide long-term carbon-neutral solutions for the transport and energy-intensive industrial sectors, in particular for applications where direct electrification is not a technically and cost efficient option.

Synergies with activities in cluster 4 are possible for integrating renewable energy technologies and solutions in energy consuming industries. Complementarities with cluster 6 concern mainly biomass-related activities.

In line with the “do not harm” principle for the environment, actions for all renewable energy technologies aim to also improve the environmental sustainability of the technologies, delivering products with reduced greenhouse gas emissions and improved environmental performance regarding water use, circularity, pollution and ecosystems. In particular, for biofuels and bioenergy improving the environmental sustainability is associated to the biomass conversion part of the value chain and the quality of the product, while air pollution associated to combustion in engines falls in the scope of other parts of the WP.

The main impacts to be generated by topics targeting the renewable energy technologies and solutions under this Destination are:

  1. Availability of disruptive renewable energy and renewable fuel technologies and systems in 2050 in order to accelerate the replacement of fossil-based energy technologies.
  2. Reduced cost and improved efficiency of renewable energy and renewable fuel technologies and their value chains.
  3. De-risking of renewable energy and fuel technologies with a view to their commercial exploitation and net zero greenhouse gas emissions by 2050.
  4. Better integration of renewable energy and renewable fuel-based solutions in energy consuming sectors.
  5. Reinforced European scientific basis and European export potential for renewable energy technologies through international collaboration (notably with Africa in renewable energy technologies and renewable fuels and enhanced collaboration with Mission Innovation countries).
  6. Enhanced sustainability of renewable energy and renewable fuels value chains, taking fully into account social, economic and environmental aspects in line with the European Green Deal priorities.
  7. More effective market uptake of renewable energy and fuel technologies.

Energy systems, grids and storage

Efficient and effective network management is the key to the integration of renewables in an efficient way that ensures cost-effectiveness and affordability, security of supply and grid stability. Real time monitoring and optimisation are necessary to increase the flexibility, through solutions such as storage, demand response or flexible generation among others, to integrate higher shares of variable renewable energy. Exploiting synergies between electricity, heating and cooling networks, gas networks, transport infrastructure and digital infrastructure will be crucial for enabling the smart, integrated, flexible, green and sustainable operation of the relevant infrastructures. Besides hydrogen and batteries (addressed elsewhere), R&I in other storage technologies, in particular thermal storage but also electrochemical, chemical, mechanical and electrical storage solutions is necessary to create a set of flexibility options.

Activities on energy systems, grids and storage under this Destination will primarily focus on the systemic aspects to enhance the flexibility and resilience of the system, in particular: integrated energy system planning and operation, engaging consumers and providing new services, electricity system reliability and resilience, storage development and integration and green digitalisation of the energy system.

Moreover, the role of citizens and communities is key when it comes to making the flexibility at appliance level available for the grid. Related to this, the inclusion of social sciences and humanities (SSH) where relevant is essential to build the social acceptance of new energy technologies and increase participation of consumers in energy markets.

All projects will contribute to an increased capacity of the system to integrate renewable energy sources and less curtailment at transmission and distribution level. The main expected impacts are:

  1. Increased resilience of the energy system based on improved and/or new technologies to control the system and maintain system stability under difficult circumstances.
  2. Increased flexibility and resilience of the energy system, based on technologies and tools to plan and operate different networks for different energy carriers simultaneously in a coordinated manner that will also contribute to climate neutrality of hard-to-electrify sectors.
  3. Enhance consumer satisfaction and increased system flexibility thanks to enabling consumers to benefit from data-driven energy services and facilitating their investment and engagement in the energy transition, through self-consumption, demand response or joint investments in renewables (either individually or through energy communities or micro-grids).
  4. Improved energy storage technologies, in particular heat storage but also others such as electrochemical, chemical, mechanical and electrical.
  5. Foster the European market for new energy services and business models as well as tested standardised and open interfaces of energy devices through a higher degree of interoperability, increased data availability and easier data exchange among energy companies as well as companies using energy system data.
  6. More effective and efficient solutions for transporting off-shore energy thanks to new electricity transmission technologies, in particular using superconducting technologies, power electronics and hybrid Alternate Current – Direct Current grid solutions as well as MT HVDC (Multi Terminal High Voltage Direct Current) solutions.

Carbon capture, utilisation and storage (CCUS)

CCUS will play a crucial role in the EU Green Deal for the transition of energy-intensive industries and the power sector towards climate neutrality. Supporting R&I for CCUS will be particularly important in those industries where other alternatives do not yet exist like the cement industry. This will be highly relevant towards 2050, when most electricity will be coming from renewables, but the need to tackle the process emissions from industry will continue. If CCUS is combined with sustainable biomass, it could create negative emissions.

Low carbon hydrogen from natural gas with CCUS could also play a significant role in industrial climate neutrality, in the transition towards full use of hydrogen from renewable sources, in particular in industries such as steel making, chemicals, or refining where large quantities of hydrogen are needed. CCUS would enable early, clean hydrogen at scale. The hydrogen infrastructure built for clean hydrogen with CCUS could be also shared by hydrogen from renewable sources. It is thus important to develop CCUS for industrial clusters, including aspects of system planning, shared infrastructure solutions such as buffer storage, shared CO2 and hydrogen transportation and infrastructure optimisation for CCS and CCU.

Demonstration of the full CCUS chain is needed in the EU, with special emphasis on the reduction of the energy penalty and cost of capture and on ascertaining safe storage. Under the EU Strategic Energy Technology Plan (SET Plan) ambitious R&I targets have been set in agreement with the sectorial stakeholders. The focus is on CO2 storage appraisal, cost-reductions, new technologies and proliferation of pilots and demonstrators.

Synergies with cluster 4 exist on the use of CO2.

The main impacts to be generated by topics targeting the renewable energy technologies and solutions under this Destination are:

  1. Accelerated rollout of infrastructure for CCUS hubs and clusters.
  2. Updated authoritative body of knowledge on connecting industrial CO2 sources with potential ‘bankable storage sites, providing greater confidence for decision makers and investors.
  3. Proven feasibility of integrating CO2 capture, CO2 storage and CO2 use in industrial facilities. Demonstrating these technologies at industrial scale shall pave the way for subsequent first-of-a-kind industrial projects.
  4. Reduced cost of the CCUS value chain, with CO2 capture being still the most relevant stumbling block for a wider application of CCUS.
  5. Adequate frameworks for Measurement, Monitoring and Verification (MMV) for storage projects, to document safe storage and for public acceptance of the technology.

Description of call
"Energy system modelling, optimisation and planning tools"

Expected Outcome

  • Provide regional, national and European public authorities and network operators, with customisable open source models of the components of the energy system, as well as tools to assemble these component models into a model of the energy system integrating the infrastructure related to all energy carriers in a given geographical area, with static and dynamic modelling capabilities.
  • Provide regional, national and European public authorities and network operators, with an open source tool to allow them to better plan and optimise the development of renewable and low emission energy sources and the enhancement of infrastructure (including storage) to meet the future energy needs in a geographical area, while minimising the total investment and operation cost, hence satisfying the future final uses of energy (sometimes used as a feedstock) by consumers, at lowest cost and with better quality of service.


Advanced modelling tools to perform regional / cross-border and cross-energy vector system planning and optimisation on a long time horizon, where cross-sectoral disruptive innovations in industry, mobility and building sector can be included

Building on existing open source models or on the opening of currently proprietary models, as far as they are available, the project should develop and validate open source models of the components of the energy system and provide tools to integrate these component models into a system model to satisfy the (future) needs in a geographical area, thereby providing a planning tool for cost and emissions optimisation of the enhanced energy system at pan-European level. The aim is to better plan and optimise the expansion of the energy generation and transmission and storage systems to meet the (future) energy needs aggregated at a granularity level finer or equal to the NUTS2 level; the distribution layer to individual energy users is not to be considered.

The open source modelling tool should be composed of the most relevant of the following modules:

The multi-physics component models is expected to model the cost (CAPEX, fixed and variable OPEX, economic lifetime) and technical performances (including GHG emissions) of the components, they should be parametrised to take into account the local climate and socio-economic characteristics of the geographical area where they will be located, as well as the time-dimension, such as the season and time of day. The component models should be capable of dynamic modelling with appropriate time steps (e.g. quarterly or hourly power profile of sources for intraday balance assessment; weekly or monthly profile for seasonal balance). The component models need to be described with standard modelling languages and be modular, so that each one can be updated without impact on the others and can be assembled with other models. They should cover most of the components in the following list, at the very least one component in each of the 9 categories below:

  • Renewable energy sources: energy production units of several typical sizes, covering technologies, such as for example photovoltaic, concentrated solar power, solar thermal, geothermal, onshore wind, offshore wind, hydroelectric, tidal, wave, biogas, biomass … Modelling of their cost, GHG emissions, typical (average) production performance of the sources, taking into account (where applicable): the season (month of the year), time (hour of the day), geo-location (at NUTS-2 level), and other parameters that can affect cost/performance. Where applicable, the statistic variability of their performance should be given and power profiles should be generated, for running dynamic simulations when the component modules will be integrated into system modules. A large-scale source should have its own model, small-scale sources (such for example wind turbines or household PV) should be aggregated (e.g. households PV aggregated at the level of a city).
  • Non-renewable primary energy sources (natural gas, coal, oil, uranium …): extraction, import; modelling of the cost, capacity, GHG emissions and geolocation.
  • Non-renewable energy conversion: refineries producing fuels or hydrogen; modelling the cost and performance (including GHG emissions) of the conversion from the primary energy carrier to secondary energy carriers, including CCS where applicable.
  • Non-renewable electricity production (coal, natural gas, oil, nuclear …): cost and performance of existing or new power plants, including CCS where applicable; modelling the transformation from the primary energy carrier to electricity (including GHG emissions).
  • Renewable energy conversion: production of hydrogen and other renewable or low-emissions gaseous or liquid fuels; modelling of their cost and performances (power, efficiency …); modelling the conversion from the primary energy carrier to secondary energy carrier and by-products (O2, CO2, including GHG emissions …).
  • Energy storage models: stationary batteries (large scale and house), electric vehicle batteries, hydropower storage, thermal storage, methane storage, hydrogen storage … ; modelling of their cost and performances: power, efficiency, capacity, life expectancy, state-of-charge (for dynamic modelling), life cycle GHG emissions.
  • Transport pipelines (including recompression stations): cost (per km) and performance (capacity, efficiency, GHG emissions) of existing and new natural gas, hydrogen, CO2 pipelines, district heating/cooling pipelines or of upgrading pipelines to admixtures of renewable gasses or to pure hydrogen or to CO2; as well as other infrastructure (e.g. LNG terminals) or logistics (e.g. transport by ship).
  • Transmission power lines: cost (per km) and performance (capacity, efficiency), of existing or new power lines, or for upgrading existing power lines to higher voltage/capacity.
  • Energy consumers: modelling of the energy use profile of typical consumers (industry, buildings, households, local heat networks, mobility and transport) for the different types of energy carriers, taking into account (where applicable): the season (month of the year, and associated average temperature), time (hour of the day), geo-location (at NUTS-2 level), and other parameters that can affect their energy use. Where applicable, the statistic variability of their performance should be given and power profiles should be generated, for running dynamic simulations when the component modules will be integrated into system modules. Where applicable, their capability to shift their consumption in time (demand response) and to store energy should be modelled, including the cost of this flexibility service. A large-scale user should have its own model; small-scale users, such for example household or eVehicle and (bi-directional) charging or refuelling stations, should be aggregated at the level of a city or NUTS2 region.
    New methods to take into accounts new types of assets connected to the grids (Electric Vehicles (EV), microgrids, storage, small scale production, non-synchronous generators, etc.) and considering the cost-effective coupling with other energy networks.

System modelling, planning and optimisation tool:

  • A system modelling tool should be developed to integrate the models of the components located in a geographical area into a system model. The models will use available data on the future needs of industry and other end-user sectors. The system modelling tool should allow both static and dynamic simulations, to assess the intraday, weekly and seasonal balances and associated grids stability. The modelling tool has to be modular and open to ensure coupling with other models, for example models including the exchange of resources and materials (enabling industrial-urban symbiosis and circularity), as well as socio-economic and market models.
  • Based on the system model, an optimisation and medium-long term grid planning tool should be developed to optimise the development pathways for renewable energy and other low emissions sources, storage and the enhancement of infrastructure, to meet the future energy needs in a geographical area, while minimising the total investment and operation cost, hence satisfying the future final uses of energy vectors of consumers, at lowest cost and climate impact.
  • Visualisation tools should be developed to support the system modelling, the optimisation process and their results, notably in the format of dynamic energy heat maps. The compatibility of the results format with the JRC visualisation tools should be ensured.

Validation of the models and tools:

  • Methodologies and procedures should be developed for the certification of the components models and, if possible, system models.
  • The component models, system modelling and optimisation tools need to be validated by using them in support of the planning of the energy transition of two real-life geographical areas: one macro-region (e.g. several small or large countries) and one large (possibly cross-border) industrial cluster. The validations should cover the range of models and tools developed, and should therefore include in particular the dynamic modelling of relevant energy sources (intermittent and dispatchable), different existing or new energy networks, conversion between different energy vectors, energy storage and energy consumers capable of demand response.

The component models and the system modelling/optimisation tools need to be a properly documented and open source development allowing the EC, the Member States and Associated Countries and other public authorities or private organisations to use the tools for their planning needs, or to develop additional add on modules. The models and tools, as well as the relevant documentation and user guides, should be published under an appropriate open license and made available to the modelling community on the Energy Modelling Platform for Europe. The results of the project have to be disseminated, notably at the EMP-E annual conference. Upon completion of the projects presently supporting the EMP-E platform and conference, the selected project should take over supporting the platform and organising the annual conference.

The research should entail interviews with relevant grid operators and public administrations in all EU Member States/ Associated Countries, so as to collect their views on how the tools could best meet their needs. At least 2 interviews per MS/AC should be foreseen.

The development of the models, simulation, optimisation and visualisation tools will be closely coordinated with Commission services (including the Joint Research Centre).

The selected projects are expected to contribute to relevant BRIDGE activities.
