Abstract:

Climate change and the desire to improve breathing air quality in urban areas are the main factors that have led to legislative changes in the use of green energy sources, including in the field of individual transport. In Romania there are a number of legislative facilities designed to encourage the sale of electric propelled vehicles (EV & PHEV) by providing checks on the purchase of such a new car, or tax exemptions/reductions. One of the reasons why the number of EV&PHEV units sold in Romania is not higher is also due to the fact that the number of charging stations is not sufficient and without proper regional coverage.

The SMiLE-EV project proposes the deployment of fixed and mobile EV & PHEV charging stations to meet the mobility needs of tomorrow's society and to prepare active/potential industrial partners for knowledge/technology transfer at the component or system level in prepare launching new products. Thus, 4 Romanian research entities, 2 universities and 2 institutes (covering the three historical regions of the country), as well as 10 potential industrial partners benefiting from the resulting technologies/products, joined in this effort. Moreover, the SMiLE-EV project is an opportunity for (re)launching the research activities of the 4 partners in areas such as: fast EV&PHEV charging solutions, H2-based energy sources integrated into charging stations, energy management of the mobile station, the exploitation of the available energy in the public transport network, efficient propulsion solutions, the connection/adjustment of the Romanian energy/environment legislation to the new challenges posed by the use of EV&PHEV stations. Through the involvement of a young / mixed workforce, the SMiLE-EV project contributes to the formation of researchers oriented towards products with high marketing potential.

Abstract:

The HORESEC project supports intelligent specialization in the energy field through a holistic analysis of renewable energy sources impact on climate change and on each other, fulfilling the objectives of sustainable development as well as advanced and progressive knowledge. Accelerate integration of RES set a new world record regarding grid’s capacity to absorb intermittent energy, which is specific to renewable energy production, was driven by a fast reduction of related technologies expenses. Increased share of RES in energy production greatly complicates the operation of current systems requiring new long-term storage solutions, developed in the HORESEC project. It will be carried out on a pilot plant test solutions for dynamic adaptation of the system to increase RES share in the energy production, including long-term storage solutions. The objectives are: Establishing the main climatological and environmental parameters with impact on RES and reciprocally. By realizing the mathematical model of the analyzed factors evolution, will be identified the climatological, environmental and social indicators associated with the RES dynamics, which will be subsequently verified on the developed pilot installation; Efficiency of energy production through new technologies and algorithms to optimize the RES response by developing new methods and measurement models; By analyzing complex compounds of biofuels, will be defined a matrix of biofuels, which shall be tested on a pilot combustion plant and on a diesel engine with the aim of obtaining new patentable technologies. The use of biomass will take place in an integrated stream with the production and storage of hydrogen and methanisation and ultimately sustainable reduction of CO2 emissions; Finding innovative storage solutions for medium and long term; Demonstration of project feasibility through experimental determinations on a pilot plant, facilitating the acquisition of research results by the industrial environment.

Abstract:

The project assesses the redox flow batteries potential as a power source for hybrid electric vehicles. 6kWh-EV-BAT product purposed by the present project is a NEW and performant product for the Romanian and European market, which will be produced in Romania for the first time. The EV-BAT system is designed as a hybrid concept between Vanadium Redox Flow Battery and Hydrogen Fuel Cell, for energy management in an electric vehicle, with zero emission. The 6 kWh-EV-BAT system is designed to be installed on a light minibus, in order to be implemented on the Romanian and international market as battery with fast charging capacity as main source of energy in light electric minibus

The project is totally innovative and is built on few original approaches which are novel at both national and international level. The novelty and originality of the project is related to:

• Electrode concept and improved electrode design of the RFC, compared with VRB system (fuel cell derived electrodes, highly conductive, very thin and high surface area) (NEW approach at intervational level).

• Activated electrodes with oxygen functional groups (e.g. C-O; C=O and C-O-H) in order to enhance the electrochemical performance of RFCs, by increasing the catalitic activity of the electrode toward vanadium oxydation / reduction. Materials used and the method for activation are NEW approach at intervational level.

• Active EV-BAT unit with charge/discharge efficiency greater than 85%, improved physical characteristics (eg. size, weight) and reliable in exploitation, thereby providing a commercially viable electric power system for electric vehicles (NEW approaches at intervational level).

Technical and scientific barriers that will be lifted by carrying out the project

• Lifting technical limitations of classical storage systems based on lead-acid battery.

The primary advantage of the lead-acid batteries is their low capital cost and easy availability. The battery demonstrated the value of stored energy in the grid, but its limited cycling capability, along with high maintenance, made its life-cycle cost unacceptable. ► The present project offers an international competitive EV-BAT product for energy storage, reliable and no limitation in exploitation comparing with classical battery systems. The main characteristics of the EV-BAT system, as opposed to other electrochemical storage batteries are: (1) simplicity of the electrode reactions, (2) no cycle life limitations, (3) electrochemically reversible reactions, (4) high overall energy efficiency (>85%), (5) no problems in deep discharge of the system and (6) no inversion of polarity if one cell of the system fails.

• Lifting technical limitations in batteries performances for electric vehicles. One of the main demands of electric vehicles is to meet the proper battery which allows fast charging (less than 5 minutes) and high number of charge / discharge cycles. Li-ion may support up to 1000 charge / discharge cycles, while the time of charging last up to 8-12 hours. The project offer a solution which allow dual charging, by replacing the electrolyte (3-5 minute) or by grid connection (8-12 hours). Supplementary, the EV-BAT model has not limitation in charge / discharge number of cycles, supporting up to 15000 – 20000 cycles, The battery is environmental friendly, 98% recyclable.

Abstract:

Prezentul proiect se încadrează în obiectivele de cercetare şi dezvoltare Europeană pentru cercetare şi inovare, privind energie eficientă, curată şi sigură, şi în special la trecerea la un sistem energetic fiabil, durabil și competitiv, în contextul diminuării constante a resurselor, al creșterii nevoilor de energie și al schimbărilor climatice prin integrarea surselor regenerabile de energie. Pentru a putea face faţă problemelor care vor apărea în asigurarea adecvanţei sistemului energetic şi extinderii cotei SRE integrate pentru perioada 2020-2030 este necesar de elaborat soluţii tehnice inovative. Proiectul dat are ca scop stabilirea măsurilor necesare de realizat pentru asigurarea adecvanţei sistemului energetic, identificarea noilor oportunităţi de majorarea a cotei SRE integrate în sistemul energetic, şi majorarea capacităţii de absorbţie a unei cote sporite de energie generate din SRE. La baza realizărilor vor sta cercetările efectuate în această direcţie de echipă, prin schimbul de experiență și accesul la infrastructura de cercetare de scară medie și înaltă. Totodată, se vor analiza inovaţiile existente în acest domeniu şi posibilitatea de adaptare/modificare a acestora pentru cazul sistemului energetic moldovean cu considerarea planurilor viitoare de dezvoltare.
