In Europe, it currently takes an average of 171 km for food to travel from farm to kitchen, and global food logistics account for a staggering 26% of global carbon dioxide emissions. Despite this, large quantities of food are wasted daily. The FoodMAPP project seeks to address these challenges in line with the European Strategic Plan for reducing the impact of climate change. This plan involves strong and influential changes in the food industry, including reducing food waste and changing the fragile and complex delivery chains of industrial producers to create a new, fair, and sustainable food industry.
The FoodMAPP project aims to optimize food supply chains by reducing waste and promoting local food production. It is funded by the Horizon Europe Marie Sklodowska-Curie program for researcher exchange, together with additional funding from the United Kingdom Research and Innovation (UKRI) program for research and innovation. The project aims to support the transformation of food delivery chains by enabling and promoting transparent local supply from local production, including family farmers and processors, directly to customers. Over four years, extensive market intelligence will be gathered from all stakeholders involved to understand market needs and preferences, with the goal of achieving a transparent localized food supply chain. This knowledge will be applied in the form of precise information to all stakeholders, laying the foundation for a new phase of a dynamic geoinformation search platform for local producers to supply and sell directly to consumers.
The project will support an interdisciplinary consortium of European partners, which includes FER as the Croatian representative, as well as technical, business, food, and social academic partners from England, Spain, Belgium, and Hungary, and industrial partners from France and Austria. The project coordinator is Assoc. Prof. Dr. Vinko Lešić from the Laboratory for Renewable Energy Systems - LARES at the University of Zagreb Faculty of Electrical Engineering and Computing, and partners include Ghent University (Belgium), Eötvös Loránd University (Hungary), CREDA (Center for Research and Development of Agri-food, Spain), and Bournemouth University (United Kingdom). Food industry partners are the Institute Paul Bocuse (France) and Ronge & Partner (Austria).
The project began on March 1, 2023, and a kick-off meeting was held on March 6-7 at FER, which hosted world-renowned academic and industrial representatives.

The final workshop of the DanuP-2-Gas project entitled: "Possibilities and potentials of using power-to-gas technology" was held in the hall of the Croatian Chamber of Commerce on 24th of November 2022. Project results and developed tools intended for different stakeholders in the Danube region were presented at the workshop by the Croatian project partners.
The event was enriched by interesting guests. Mr. Vjekoslav Jukić from Ministry of Economy and Sustainable Development gave a presentation on the Croatian legislative framework related to hydrogen and potential financial tools and reported on the progress of the North Adriatic Hydrogen Valley established.
Danica Maljković, PhD, (Indeloop d.o.o.), Tonći Panza, M.Sc. (Adria Wind Power d.o.o), Krešimir Ižakovic, M.Sc. (Dilj d.o.o.), Dinko Đurdevic, MBA (Hydrogen Europe) and Ante Sjauš, M.Ll (Zadar County) participated in an interesting panel discussion „Croatia's potential in hydrogen value chains“ moderated by Ivona Hulenić, M.Sc. (EIHP).
Within the DanuP2Gas project, in which FER with LARES participates as a project partner, two new tools for different stakeholders in the Danube region were developed.
The aim of the tools is to stimulate interest in possible investment projects in power-to-gas hubs, as well as to reveal potential obstacles in their realization.
The transnational atlas of renewable energy is an online tool in the form of a web geo-information system (GIS), shows various existing infrastructure elements for the planning of P2G hubs in Germany, the Czech Republic, Slovakia, Austria, Slovenia, Hungary, Croatia, Serbia, Romania and Bulgaria.
The DanuP-2-Gas Optimization Tool is an off-line tool that provides an economically optimal unified proposal for structuring the conversion and storage processes in the hub and for their year-round operation profiles, for the selected point and infrastructure elements in the transnational atlas. Subsequent manual correction of all data downloaded from the atlas is possible, and it is also possible to enter data completely manually without using the atlas. Along with the optimal result, it provides an accompanying economic and technical analysis: the time and amount of consumption of input resources, the products of P2G hubs that are handed over to consumption chains, and the associated emissions. The Optimization Tool can be downloaded for free and the Atlas reached at the Danube Energy Platform.
The DanuP-2-Gas Optimization Tool was developed by LARES members Filip Rukavina M.Sc., Antonio Karneluti M.Sc., and Marijo Šundrica PhD, mentored by DanuP-2-Gas local project leader and LARES head Prof. Mario Vašak.

For those working in the sector of energy efficiency, we present the Optimal sizing calculator developed by LARES team within the project Store4HUC, financed trough the Interreg Central Europe programme. It is an in-depth tool for the advanced users like energy experts and others working in that field. Optimal parameterisation of photovaltaic and battery energy storage systems are supporting the customers to save costs and be more environmental friendly at the same time!
Photovoltaic (PV) systems are widespread renewable energy sources that can be installed at a variety of locations. Because of their sun dependence, they provide more than enough energy during the day, but no energy during the night. Since the prices of selling electrical energy to the utility grid are considerably lower than the prices of buying the energy, having a battery energy storage system (BESS) can ensure that the excess of energy is stored and used later. Not only does a PV system in a combination with a BESS reduce monthly electricity bill for a consumer, it equally contributes to the environmental protection in terms of reduced CO2 emissions.
To maximize the contributions while minimizing the price of the installations, the calculator finds the optimal sizes of a PV and a BESS for a site. Those sizes are peak power of the PV system, energy capacity and power converter rated power of the BESS. The calculator uses typical yearly consumption profiles of a variety of consumers, but if you have your own consumption profile recorded you can use it to calculate your optimal parameters more accurately.
You can download this valuable tool for free here and soon find out your optimal kWp-kW-kWh combination!
In this short video our researcher Filip Rukavina is explaining how to download the Optimal Sizing calculator, install it and get it started.
If you have problems with the tool, feel free to contact us under:
PC 2021 – 23rd International Conference on Process Control took place on 1st - 4th June 2021 in Štrbské Pleso, Slovakia. Our LARES research team presented three papers:

Within the framework of the project Store4HUC, co-funded by the European Union through the Interreg Central Europe programme, where LARES is involved, a public building in the municipality of Lendava was converted from fossil fuels to renewable energy. Symbolically, on World Earth Day, 22 April 2021, the Mayor of the Municipality of Lendava, Mr. Janez Magyar, handed over the pilot project in the field of renewable energy and its storage. At the handover of the modernized boiler room in the Lendava Library building, which will henceforth be heated by geothermal energy, the Mayor of Lendava highlighted the municipality's efforts to become recognizable as a green tourism destination: "With small steps, but persistently, we contribute to the carbon-free society, as we are aware of the importance of preserving nature and natural resources, so we decide to make the most of renewable energy sources." The pilot infrastructure is a latent heat storage system combined with geothermal energy. This will reduce energy costs, which will also have a positive impact on greenhouse gas emissions. The Municipality of Lendava is aware of its role and supports projects that have a positive impact on the environment. The project can also be a good example and encouragement both locally and in the wider environment.
The latent heat storage based on phase-change materials represents a challenge for energy management as its model is highly nonlinear. LARES contributes here with development of an energy management procedure based on mixed-logical-dynamical systems and predictive control that unlocks the full potential of such a storage system such that the operators of the plant can be advised how to improve the system performance for the one-day-ahead operation horizon. Careful planning almost fully eliminates the need for engagement of the oil-based backup system and thus enables a completely carbon-free heat supply of the library in Lendava.
The project "Development of a System for Predictive Control and Autonomous Trading of Energy in Buildings - PC-ATE Buildings'', co-financed by the European Regional Development Fund, deals with the problem of predictive control of energy consumption at the building level under comfort constraints and with autonomous trading of energy between buildings, in cooperation with our partners, Klimaoprema d.d.

New online tool calculates savings through urban electric storage solutions developed in the course of the EU financed project Store4HUC, in whose project team LARES is involved
Up to 80% of total energy consumption in the EU is attributed to urban areas, including historical urban centres. At the same time, low carbon energy supplies in the form of energy storages, especially in historical urban centres, is a rarity in central Europe. This is mainly because of strict architectural protection constraints, higher implementation costs and often also conflicts with town planning policies. The Store4HUC project now offers the Autarky Rate Tool to address such conflicts. This easy-to-use online tool is available for everyone who considers installing electrical storage solutions in combination with renewable energy sources. With only a few numbers and clicks, you can get an evaluation of the technical, economic and ecological effects of a chosen combination. It is now possible for everyone who plans to change to renewable energy use and needs electrical storage to learn how self-sufficient the planned change will make them. The tool is freely accessible and available to all those interested in the installation of electrical storage in combination with renewable energy sources. The aim is to motivate the users to deal with the topic in more detail and subsequently to contribute to an increased and intelligent use of electric storage solutions and contribute to the reduction of carbon-based energy sources. The tool is available online via https://www.interreg-central.eu/Content.Node/news/2.html

Ths is done through coupling the electric power, gas and biomass sectors. Within the project LARES focusses on the optimization tool for parametrization and operations planning of sectors coupling hubs that will aid in decision making when it comes to investing in such hubs and operating them in different parts of the Danube Region.
FER/LARES participates in the project as partner and the lead partner for the project is Technology Centre Energy -- University of Applied Sciences Landshut from Germany. The project is funded from European Regional Development Fund and IPA funds via Interreg Danube Transnational Programme.
More details about the project are provided in the detailed news content.
This September saw the launch of the European project Resilient Water Innovation for Smart Economy - REWAISE, within the Horizon 2020 research and innovation programme. The aim of REWAISE is to create a new “smart water ecosystem”, to result in a carbon free, sustainable hydrological cycle, in line with the concept of a resilient circular economy, recovering energy, nutrients and materials from water.
To embrace this concept and emphasize the true value of water, the project develops an intelligent digital platform for decentralized solutions and decision making, involving all relevant stakeholders within Living Labs to share best practices and facilitate co-creation.
University of Zagreb Faculty of Electrical Engineering and Computing is through its Laboratory for Renewable Energy Systems heavily involved in REWAISE developments during 5 years of its run. FER/LARES will develop optimal control procedures for plants and systems in the water cycle -- freshwater preparation plants, water distribution systems, sewage collection system and wastewater treatment plants -- to ensure they operate at their socio-economical optimum. It will then also develop procedures for coordination between independent plants and systems in the water cycle based on supply-demand economical mechanisms to further reduce its overall socio-economical cost and environmental footprint. The developed optimal control and coordination procedures will be implemented and tested in water cycles of Mediterranean, Atlantic and Continental hubs of REWAISE living labs.
Together with many research positions with regards to a considerable number of new research projects grants, we also have different non-research, administrative staff positions.
Currently open positions can be found in our Open positions tab.
