The transition to the smart grid era is associated with the creation of a meshed network of data contributors that necessitates for the transformation of the traditional top-down business model, where power system optimization relied on centralized decisions based on data silos preserved by stakeholders, to a more horizontal one in which optimization decisions are based on interconnected data assets and collective intelligence. Consequently, the need for “end-to-end” coordination between the electricity stakeholders, not only in business terms but also in exchanging information is becoming a necessity to enable the enhancement of electricity networks’ stability and resilience, while satisfying individual business process optimization targets of all stakeholders involved in the value chain. SYNERGY introduces a novel reference big data architecture and platform that leverages data, primary or secondarily related to the electricity domain, coming from diverse sources (APIs, historical data, statistics, sensors/ IoT, weather, energy markets and various other open data sources) to help electricity stakeholders to simultaneously enhance their data reach, improve their internal intelligence on electricity-related optimization functions, while getting involved in novel data (intelligence) sharing/trading models, in order to shift individual decision-making at a collective intelligence level. To this end SYNERGY will develop a highly effective a Big Energy Data Platform and AI Analytics Marketplace, accompanied by big data-enabled applications for the totality of electricity value chain stakeholders (altogether integrated in the SYNERGY Big Data-driven EaaS Framework). SYNERGY will be validated in 5 large-scale demonstrators, in Greece, Spain, Austria, Finland and Croatia involving diverse actors and data sources, heterogeneous energy assets, varied voltage levels and network conditions and spanning different climatic, demographic and cultural characteristics.

HERCULES introduces a novel breakthrough approach towards thermal energy storage of surplus renewable energy via a hybrid thermochemical/sensible heat storage with the aid of porous media made of refractory redox metal oxides and electrically powered heating elements. The heating elements use surplus/cheap renewable electricity (e.g. from PVs, wind, or other sources) to charge the metal oxide-based storage block by heating it to the metal oxide reduction temperature (i.e. charging/energy storage step) and subsequently (i.e. upon demand) the fully charged system transfers its energy to a controlled airflow that passes through the porous oxide block which initiated the oxidation of the reduced metal oxide. It is an exothermic process thus a hot air stream is produced during this step which can be used to provide exploitable heat for industrial processes. The proposed research will be conducted by an interdisciplinary consortium constituting leading research centers, universities, innovative SMEs, and large enterprises including ancillary service providers and technology end-users.

This project aims to develop and validate (to reach TRL 4) a novel thermochemical technology that not only can store mid-temperature heat (250-400 deg C)This project aims to develop and validate (to reach TRL 4) a novel thermochemical technology that not only can store heat at competitive cost and very high efficiency but also may upgrade that to considerably higher temperatures. This way, the technology enables the upgrade of medium-temperature heat to drive high-temperature and more efficient power cycles, e.g. supercritical. The heat is stored in the form of chemical bonds making it suitable for a long-duration and seasonal storage solution for power and heating applications This novel and outstanding heat storage/upgrading concept offers some further important features that make it even more promising. These are its i) competitive cost-effectiveness compared to other technologies due to its expected long lifespan, and design/operation simplicity, ii) compatibility with a variety of heat sources (solar collectors, industrial waste heat, electricity, etc.), and power blocks, upon the right material selection, iii) capability of continuous discharging with periodic charging as a requirement for many power cycles upon proper sizing/design, iv) scalability up to several-hundred MWhs of capacity and storage duration from several days to even seasonal with minimal losses, v) no environmental impacts, toxicity, and human health issues, and vi) many more potential applications upon further and case-specific developments in the future. The consortium consists of 9 partners from all corners of the EU; including 3 universities, 1 research center, 2 SMEs, 2 large enterprises, and 1 NGO, ensuring that all required expertise exists for the successful accomplishment of the project and future exploitation, and also the partners optimally supplement each other. The technology will be demonstrated in different designs and integrations at 5 kW heat capacity at the DLR laboratory.

Fight against climate change has its main battlefield at the energy sector. Electricity and transport are the largest contributors to GHG emissions; the trend in transport toward electric vehicle will increase pressure on the electricity system and fundamentally change its dynamics. With producers focused on their legitimate business targets, and consumers focused on security of supply and low prices, the burden of decarbonizing electricity falls on policy makers as driving force, and on transport system operators (TSOs) as technical managers that ensure the safety and stability of supply. Grid stability is a delicate equilibrium, where some agents provide stability via ancillary services (regulating voltage and frequency) and others rely on that stability (consuming energy and/or disturbing the frequency due to embedded capacitors/impedances); power producers are usually stabilizers (synchronous turbines that provide inertia against sudden changes). Penetration of non-synchronous renewables such as Wind and PV threatens to disrupt the balance, especially in islands and poorly interconnected areas, as they provide power but rely on stability provided by others; this forces the system to have lots of synchronous generators idle just for stability, which is inefficient and costly. GRIDSOL wants to change the approach: we propose Smart Renewable Hubs, where a core of synchronous generators (CSP and biogas combined cycle HYSOL) is integrated with PV under a dynamic control system (DOME), self-regulating and providing ancillary grid services thanks to firm, flexible generation on a single output, tailored to a specific location, relieving pressure on the TSO. The project will research an advanced control (DOME) to ensure operation efficiency and grid stability with higher RES penetration, and a multi-tower concept for CSP cost reduction and efficiency improvement, to provide secure, clean and efficient electricity by getting the most of each renewable primary source.
