Periodic Reporting for period 2 - HYBRIS (Hybrid Battery energy stoRage system for advanced grid and beHInd-de-meter Segments)

Reporting period: 2022-07-01 to 2024-12-31

Summary of the context and overall objectives of the project

HYBRIS is an integrated, 4-year industrially driven action that brings together 15 partners from 6 European countries with the aim to develop a novel battery enabled hybrid storage system. The novel Hybrid Energy Storage System (HESS) developed by our project is based on the battery hybridization by twinning at system level of two of the best energy storage technologies available: Lithium Titanate (LiTO), a high power density component, and Aqueous Organic Redox Flow Batteries (AORFB), a high energy density component. These two technologies are coupled with the development of a breakthrough Battery Management System, Novel Power Electronics and an advanced Power Management System which is fully integrated with Energy Management Systems (EMS) and grid systems

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Here's an overview of the results and their exploitation and dissemination at the end of HYBRIS Project:
1. AORFB cell stack
The main idea is to commercialize alternative materials-based AORFB. According to further results it could change and patent and/or publication could be considered.
Further work will evaluate long term stability of selected materials in battery operating conditions

2. Advanced Battery Management System
At this stage, no commercial application on CEA side, but licences can be discussed. CEA could propose it for further research projects requiring such advanced BMS services (for diagnosis and prognosis) without needing to develop all from scratch. Exploitation of Hybris operation data is key to test and validate ABMS deployment, performances (including self-recalibration) and relevance for EMS.

3. Advanced Power Conversion System
AORFB and LTO assembled modules validated. Converter designed, mock-up built and validated. Proposal of new materials and devices that overcome the present technology.
Further combination of different energy storing systems can be exploited depending on its use and application. The developed converter architecture during this project to efficiently couple systems with different energy and power capabilities as well as different time responses can be further adapted for other hybrid configurations.

4. Energy Services for optimized HESS assets
The most interest currently is in the business parks that Quares manages, there is a lot of replication potential in Belgium. There are two possible business models. The first and simplest is to provide the HESS solution under Engineering, procurement, and construction contract (EPC). The second is to use an Energy as a service (EAAS) model which would require the involvement of a financing partner. and to demonstrate that the value provided by the HESS is greater than the recurring payments every year.

5. High-fidelity Virtual Demonstration Site Framework
TH plans to support the creation of similar virtual demonstration sites as part of its Energy Services offering to customers or as part of future research and development projects (in cases where new components or capabilities are necessary). Collaboration agreements with hardware and software solution providers for energy services (such as HESStec and ILECO) as part of a sales support tool development or a client focused tool are also considered.

6. Power conversion-architecture optimization tool
Develop the EDA tool into a stand-alone software application independent so it does not require the MATLAB software development tool for its execution.
Next steps are to increase the number of components in the software database so to broaden the available design space. Optimize the code to improve its execution time.

7. Simplified CFD FEM model.
This is a research activity concerning specific improvement of the cooling system of lithium batteries. There is the need to have a cost/benefit assessment about this innovation, before to move to a practical business model. We would like to continue the research on this field, trying to achieve more experimental results.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

Optimized LTO technology: A Battery Thermal Management System will be developed to maintain the battery in ideal conditions, while controlling temperature increase below 45°C, when 5C discharge current occurs. This progress allows to achieve a powerful battery (>20% of the current one) and reducing the investment cost by down size the battery system, with respect a certain reference application.

Optimized AORFB Technology with better environmental performance.

ABMS is a key innovation in order to optimize the operation and management of the HESS. ABMS is a solution for Battery Health Management, providing a full diagnostic/prognostic assessment, including early warnings, for each battery technology to enhance the maintenance and to provide updated models of each battery to allow an optimal management of the HESS with optimal dispatch of the power solicitations. This solution will also correct any information provided by the BMS on the SoH and the SoC.

Power electronics - an innovative Power converter: the novel power converter based on an interleaved configuration allowing power flow sharing and routing with the aim of optimizing components state-of-health (especially relevant for semiconductors which are one of the elements that fails the most on power converters) as well as increase on the efficiency (which is relevant for the round trip of the HESS) through the usage of novel semiconductor technology based on SiC; which is better suited for medium high power and medium-high voltage applications. In addition, such technology will help reducing the thermal losses (thus, reducing cooling requirements) which are positive for battery SOH.

Optimization and validation via HIL based Digital Twin: Given that about 80% of a issues with ESS controls are software based, the Digital Twin for HESS (DTH) technology makes it possible to lower the time necessary to size, develop, validate and pre-commission a HESS. Furthermore, a DTH enables owners
and operator to lower both CAPEX and OPEX by making the optimal decisions in different stages of the of system lifecycle, from choosing the best units and configuration of devices and sub-systems in the design phase, over virtualized interoperability testing in verification stages, to benchmarking various optimization algorithms.

Devoted method for battery-based HESS integration: A bottom-up approach which leverages the use of advanced modelling to achieve a fast apply of the technology with a high flexibility and customization capability. This is contrary to other solutions in the SoA, where a top-bottom approach, mainly focused in the high control layers, leads to weaker performance in terms of the “chemistry”.

Power Management System:
• High focus into the storage technologies, including advanced models with a continuous update during the project.
• Capability of the control system to integrate multiple chemistries in a single system with extended performance.
• Real-time performance, as most of the current EMS approaches are more focused into a schedule level or an operation in periods of minutes.
• Flexible integration of new assets, modularity and interoperability thanks to the virtualization provided by the State of Function.
