Title:

Development of a closed loop regenerative high temperature pem fuel cell system

The use of fuel cells in aerospace applications is, up to date, very limited, future missions, however, will see more involvement of fuel cells in space, and this will include European Space Agency (ESA) activities as well. Reversible or Regenerative Fuel Cells (RFCS) have already been considered as potential energy storage devices for several space mission scenarios, even for Earth satellite missions. Two fields of application have been identified as suitable for the potential use of RFCS: the field of telecommunication for the replacement of batteries, and planetary exploration where RFCS would fill the gap between batteries and nuclear power sources. Current RFCS technology separates the electrolyzer cell and the fuel cell. A complete, closed-loop system based on regenerative fuel cells combined, for instance, with solar panels, would provide autonomous electrical power supply on-demand, which is of great interest and importance for space applications. Such systems are stand-alone systems, where the renewable energy source powers the system.
The objective of this activity is the development of a Regenerative High Temperature PEM Fuel Cell Stack combined with a High Pressure PEM Water Electrolysis System for space applications.
The objectives of the activity are:

  • Evaluation and testing of materials for both High Temperature PEM Fuel Cell, (HTPEMFC), and High Pressure PEM Electrolyser, (HPPEMELY), with emphasis on long life stability and performance.
  • Design both a minimum 1 kW HTPEMFC and HPPEMELY stacks for use with hydrogen and oxygen intended for closed loop operation.
  • Design a closed loop Regenerative -PEMFC system.
  • Manufacture a compact closed loop Regenerative-PEMFC system elegant breadboard.
  • The compact closed loop 1 kW Regenerative-PEMFC system shall be life tested according to a profile given by the European Space Agency.
  • Construction of a 3 kW HTPEMFC and a 1.5 kW HPPEMELY stacks. A 3 kW system will allow accurate estimation of system weight and thermal / water management strongly influencing the efficiency of the system.
  • Evaluation of a performance and efficiency of a system downscaled to 300W.

Title:

Regenerative Fuel Cells For Mars Exploraion

This activity focuses on a regenerative solid oxide fuel cell system, (RSOFCS), that use carbon dioxide (CO2) as main medium. CO2 is available directly in the Martian atmosphere. These cells when charging absorb electric energy and electrolyse CO2 into carbon monoxide, (CO), and oxygen (O2). These two reactant gasses are then stored. When the cells discharge, CO and O2 are recombined back into CO2 with production of electric energy. These cells, which operate at high temperature, are fully reversible (i.e. the cell works both as electrolyser and as fuel cell) unlike low temperature cells that have, for reasons of catalysis and efficiency, a dedicated electrolyser and a dedicated fuel cell stack.
The objectives of the activity are to:

  • Design, develop and test a small scale demonstrator of reactant generation (pre-pressurization and electrolysis) and storage system.
  • Design and develop a complete 500 W RSOFC system breadboard with a storage capacity of 10 kWh for use on Mars landers, operated solely from CO2.
  • Test the RSOFC system breadboard according to the test specification given by ESA. The test plan aims not only at verifying the compliance with requirements established early in the activity, but also at characterizing the performance and operational aspects of the cells.

Title:

Production of Energy Carriers from Biomass By-Products

The Glycerol2Energy project intends to investigate several possible ways for the exploitation of crude glycerol, aiming at the development of efficient and commercially viable process for the production of renewable energy carriers such as hydrogen, hydrocarbons and higher alcohols. The primary objective of the Glycerol2Energy project is to develop and evaluate in a bench scale innovative process for the production of renewable energy carriers, using a raw material crude glycerol originating from biodiesel industries. Researching the most active, selective and stable catalytic materials for glycerol reforming under various reaction conditions and reactor types, studying the fundamental catalytic phenomena and investigating the optimal catalyst/reactor configurations will be a major part of the project. Exploring the use of syngas produced from glycerol produced from glycerol reforming for the synthesis of higher alcohols is the other important part of the project.

Title:

High Specific Energy Lithium Cells for Space Exploration

Li-ion batteries are one of the most successful stories in modern electrochemistry. These batteries, which became a commercial reality about 2 decades ago, are dominating the markets with increasingly wider applications, including space applications. Present challenges are to extend their use to high power and large size applications (e.g. propulsion, EV) and, specifically for space applications, to increase their specific energy density (Wh/kg) and improve their low temperature performance in order to meet the demanding requirements of space missions and man-portable applications. This project focuses on the development of a high energy density Lithium-ion cell capable of operating under low temperature conditions (as low as -40oC) which may be encountered in future exploration missions which do not consider the use of Radioisotope Heater Units. The purpose of this activity is therefore to develop, manufacture and evaluate Lithium-ion prototype cells with a target specific energy of 200Wh/Kg or more, capable of operating under low temperature conditions.
The main objectives of this project are:

  • Review of the existing state-of-the-art electrochemical systems and cells technologies and selection of the most promising electrochemical couple(s) and electrolytes
  • Development of advanced anode materials and testing of three-electrode cells based on the most promising materials
  • Development of prototype cells and evaluation under cycling tests

Title:

HyPEMRef Development of an innovative, energy efficient and environmentally friendly Power System, operating with hydrogen and fuel cell, for stand-alone refrigeration applications

The primary objective of the project is to design, construct, optimize and field-test a highly innovative, energy efficient and environmentally friendly power production system for stand-alone, out-of-grid refrigeration applications. The device will be able to convert the fuel (propane, LPG) into electrical power with intermediate production of hydrogen, by means of a high-temperature PEM fuel cell, and will supply with the demanded power a refrigerator (Ice Cold Merchandiser), resulting in an autonomous refrigeration unit. The system will be based on novel materials, devices, processes and technologies that have been recently developed by the participating bodies. The integrated unit will be specifically designed to be used mainly in remote, out-of-grid locations, where power production is very highly priced. The proposed process for LPG-to-power conversion presents electrical efficiency greater than 30%, which is more than double compared to that of conventional diesel/gasoline generators that are mainly used in similar applications. Furthermore, the proposed process is characterized by nearly zero emissions of atmospheric pollutants, such as SOx and NOx and by significantly reduced emissions of CO2, and thus of total carbon footprint. The integrated system comprises the following parts:

  • Fuel processor, where the fuel is reformed to a hydrogen-rich gas stream
  • Fuel Cell stack, where the demanded power is produced, via the electrochemical reaction of the on-site produced hydrogen with atmospheric oxygen
  • Power electronics, which store and convert the produced energy to the desired form (230 VAC)
  • Control system, which drives all the sub-units and controls the entire power system
  • Refrigeration unit

After construction of the above system, its optimization with respect to several parameters will take place. A number of 3-5 optimized prototypes will be constructed and installed in selected areas, where field testing under realistic conditions will take place.

Title:

T-CELL - Innovative SPFC Architecture based on Triode Operation

The development of Solid Oxide Fuel Cells (SOFCs) operating on hydrocarbon fuels (natural gas, biofuel, LPG) is the key to their short to medium term broad commercialization. The development of direct HC SOFCs still meets lot of challenges and problems arising from the fact that the anode materials operate under severe conditions leading to low activity towards reforming and oxidation reactions, fast deactivation due to carbon formation and instability due to the presence of sulphur compounds. Although research on these issues is intensive, no major technological breakthroughs have been realized so far with respect to robust operation, sufficient lifetime and competitive cost. T-CELL proposes a novel electrochemical approach aiming at tackling these problems by a comprehensive effort to define, explore, characterize, develop and realize a radically new triode approach to SOFC technology together with a novel, advanced architecture for cell and stack design. This advance will be accomplished by means of an integrated approach based both on materials development and on the deployment of an innovative cell design that permits the effective control of electrocatalytic activity under steam or dry reforming conditions. The novelty of the proposed work lies in the pioneering effort to apply Ni-modified materials electrodes of proven advanced tolerance, as anodic electrodes in SOFCs and in the exploitation of the novel triode SOFC concept which introduces a new controllable variable into fuel cell operation. In order to provide a proof-of-concept of the stackability of triode cells, a prototype triode SOFC stack consisting of at least 4 repeating units will be developed and its performance will be evaluated under methane and steam co-feed, in presence of small concentration of sulphur compound. Success of the overall ambitious objectives of this project will result in major progress beyond the current state-of-the-art and will open entirely new perspectives in cell and stack design.

Title:

ASYSTENI - Ammonia Synthesis from Steam and Nitrogen at Atmospheric Pressure: The Electrochemical Approach (2012-2015, NSRF)

Brief description :

Ammonia synthesis from its elements is considered one of the most important scientific achievements of the 20th century. Ten years ago, an electrochemical alternative to the classical high pressure process, developed in our Laboratory, was reported. In the present proposal, the requirement of ultra high purity Η2 is eliminated: ammonia will be synthesized from steam and nitrogen. The reaction will be studied in proton (H+) and oxygen ion (O2-) conducting solid electrolyte cells at 400-700°C and at atmospheric pressure. In the H+ cell, steam will be electrolyzed at the anode to produce protons and oxygen: H2O > 2 H+ + ½ O2 + 2 e-. Protons will be then transported through the solid electrolyte to the cathode where they will react with nitrogen to produce ammonia: 3 H+ + ½ N2 + 3 e- > NH3. In the O2- cell, H2O and N2 will be fed in together at the cathode, where H2O will be electrolyzed: H2O + 2 e- > O2- + H2 . The produced Η2 will then react with N2 to produce ΝΗ3. Hence, in both cells, the overall reaction can be written as: N2 + 3 Η2O <==> 2 ΝΗ3 + 3/2 O2. The feasibility of these processes has been tested successfully in our Laboratory. Nevertheless, a number of problems that need to be solved in order to scale-up, have been identified. The goal of the present proposal is to propose and explore means to overcome these hurdles and bring this new method into industrial practice.

Title:

H2S PROTON - Hydrogen production from H2S decomposition in high temperature proton conducting solid oxide membrane reactors (2012-2015, BLACK SEA "2007 - 2013")

Brief description :

The proposed research addresses the priority “Hydrogen production from H2S rich Black Sea Water”. The main scope is to develop a micro-structured proton conducting electrochemical membrane reactor/fuel cell that will enable the efficient exploitation of Black Sea’s hydrogen rich energy potential (>1.3 million tons). Such an innovative approach will result to the partial compensation of regional countries energy demand, rendering them as key players in the forthcoming hydrogen economy era. Hydrogen production from H2S in Black Sea consists of the following stages: a) pumping of sea water at ~1000m depth, b) extraction of concentrated H2S/H2O mixture, c) decomposition of H2S to H2 and S. The present proposal will delve in every aspect the decomposition step to form H2 in the most efficient way. The development of H+ conducting ceramic membranes is widely recognized as an important step to broad the application of protonic devices; electrochemical reactors and fuel cells. To this end, a H+ conducting cell is planned to be fabricated and operate in the co-generative mode. The anode electrode will be exposed to the concentrated H2S/H2O extraction and catalyze the decomposition of H2S and H2O to H+, S and O2. In the following, H+ will be transferred through the membrane to cathode where they will be converted either to hydrogen (reactor mode) or to H2O generating at the same time electrical energy (fuel cell mode). Simultaneously, on the anode chamber the generated S will react with O2 and excess H2O to SOX and H2SO4. This advantageous poly-generation approach will enable: i) pure H2 production at cathode from both H2S and H2O, ii) S management with H2SO4 co-generation at anode, iii) high efficiencies towards H2 due to the shift of the equilibrium and the application of the electrochemical promotion concept and iv) flexible operation for the simultaneous production and separation of hydrogen or its direct use for power generation under fuel cell operation.

Title:

CoMETHy - Compact Multifuel-Energy To Hydrogen converter (2011-2014, FP7 CP)

Brief description :

CoMETHy aims at developing a compact steam reformer to convert reformable fuels (methane, bioethanol, glycerol, etc.) to pure hydrogen, adaptable to several heat sources (solar, biomass, fossil, refuse derived fuels, etc.) depending on the locally available energy mix. The following systems and components will be developed:

  • a structured open-celled catalyst for the low-temperature (< 550°C) steam reforming processes.
  • a membrane reactor to separate hydrogen from the gas mixture.
  • the use of an intermediate low-cost and environmentally friendly liquid heat transfer fluid (molten nitrates) to supply process heat from a multi fuel system. Reducing reforming temperatures below 550°C by itself will significantly reduce material costs. The process involves heat collection from several energy sources and its storage as sensible heat of a molten salts mixture at 550°C. This molten salt stream provides the process heat to the steam reformer, steam generator, and other units.

The choice of molten salts as heat transfer fluid allows:

    • improved compactness of the reformer;
    • rapid and frequent start-up operations with minor material ageing concerns;
    • improved heat recovery capability from different external sources;
    • coupling with intermittent renewable sources like solar in the medium-long term, using efficient heat storage to provide the renewable heat when required. Methane, either from desulfurized natural gas or biogas, will be considered as a reference feed material to be converted to hydrogen.

Title:

SustainDiesel - Sustainability Improvement Of Diesel Production Technology (2011-2014, NSRF)

Brief description :

As diesel covers the 1/3 of the transportation energy in Greece, any effort to improve its sustainability is significantly important. Mixing diesel with biodiesel (produced from Fatty Acid Methyl Esters – FAME) was the first attempt to improve diesel sustainability, which however raised numerous considerations as the production of FAME-biodiesel in Greece is not sustainable.
The main premise of this R&D project is broadening of the use of RES for the improvement of diesel sustainability, by promoting the production of a hybrid 2nd generation biodiesel using Renewable Energy Sources. The producing process investigated is based on the co-hydroprocessing of petroleum fractions with waste lipids (cooking oils) and more specifically on the hydrodesulphurization of mixtures of petroleum fractions and waste cooking oil. The sustainability of diesel is further improved by using hydrogen produced from solar energy within the hydroprocessing step. Besides exploring the technological feasibility of the proposed technology, the new hybrid diesel is be evaluated in terms of quality specifications and effectiveness/applicability in conventional diesel engines. Finally, this project is also evaluating the environmental benefits, i.e. Green House Gas (GHG) emissions reduction by incorporating RES for diesel production via the investigated pathway.

Title:

ECHOCO2 - Electrochemically promoted CO2 hydrogenation for the production of clean fuels

Carbon dioxide is one of the main pollutant greenhouse gases and its high atmospheric concentration affects significantly the climatic changes globally. Therefore, control of CO2 emissions is among most important areas of greenhouse gas control according to the Kyoto protocol and the need for development of new, renewable energy sources and also for optimization of the current energy units is urgent. Towards this direction, several solutions and ideas have been proposed for the capture and storage of CO2 even at large scale, like the recently developed techniques of geological storage. The high cost of these techniques and the loss of reliability prevent them from being widely used. Another attractive approach gaining attention is the effective CO2 utilization via chemical fixation into useful chemical products; however, fixation by chemical methods is still a problem to be solved. Catalytic technologies can offer cost-effective solutions, although their potential application has not often been analyzed in detail. It is necessary to find specific solutions able to reintroduce CO2 into the chemical and energy cycles. A challenge for an energy-saving approach is the catalytic hydrogenation of carbon dioxide to obtain transportation fuels or valuable chemical feedstock such as light olefins and liquid hydrocarbons. Among the various strategies currently investigated for the utilization of CO2, the hydrogenation of CO2 to transportation fuels is the most attractive and desirable and thus constitutes one of the major and currently pressing technological challenges in heterogeneous catalysis and electrochemistry. Although CO2 hydrogenation to methanol is a well-established industrial process, no catalytic process exists for CO2 conversion to hydrocarbons suitable as transportation fuels.
The objective of this project is the development of novel chemically and electrochemically promoted processes for catalytic hydrogenations with emphasis to the hydrogenation of CO2 to useful fuels and chemicals. Electrochemical promotion of catalysis (EPOC), also known as NEMCA effect (non-Faradaic Electrochemical Modification of Catalytic Activity), is a phenomenon which allows for in situ enhancement and control of catalytic activity and selectivity via the controlled migration of promoting species from or to the catalytic metal/gas interface.

CAPSOL - Design Technologies for Multi-scale Innovation and Integration in Post-Combustion CO2 Capture: From Molecules to Unit Operations and Integrated Plants. (2011-2014, FP7 CP)

Brief description :

This project adopts a holistic approach to delivering innovation in post-combustion CO2 capture by researching and developing multi-scale computer aided methods and tools that:

      • Support intra-scale innovation within multiple levels, ranging from molecules to integrated plants (i.e. thermodynamic models of solvent-CO2 mixtures, CAMD solvent design tools, conceptual to first-principles tools for simulation, optimization, automatic control and integration).
      • Facilitate efficient inter-scale integration and result in validated and applicable solutions (i.e. advanced decision-making tools to systematically deliver novel solvent and process design options using economic, sustainability and controllability measures from unit operations to plant-wide scales).

The proposed developments are expected to identify optimum solvent-process schemes that bring the costs down to at least €15/tCO2 captured or less. The radically new approach adopted for the design of solvents and process schemes for post-combustion CO2 capture presents significant advantages compared with previous EU funded projects (e.g. CESAR).

Title:

HT-PEM-ELE - Nano-structured electrodes for water electrolysis in high temperature Polymer Electrolyte Membrane electrolyzers

A PEM (Polymer Exchange Membrane) electrolyser is literally a PEM fuel cell operating in reverse mode. When water is introduced to the PEM electrolyzer cell, hydrogen ions (protons) are drawn into and through the membrane, where they recombine with electrons to form hydrogen molecules. Oxygen gas remains behind in the water. As this water is recirculated, oxygen accumulates in a separation tank and can then be removed from the system. Hydrogen gas is separately channeled from the cell stack and captured. Nowadays, there are a plenty of commercial available PEM fuel cell units but a limited number of PEM electrolysers. In the case of PEM electrolysers, although they present advantages over the conventional alkaline electrolysers, further development is still needed in order to achieve higher efficiencies and durability while minimizing production cost. The major disadvantage of PEM electrolysers compared to alkaline is the relatively high anodic overpotential for the oxygen evolution reaction (OER). Over the last 15 years, the highest efficiency that has been reported in the literature for PEM electrolyzers operating at Tmax=90oC, was obtained either with the use of Ir or Ru oxides or with bimetallic oxides such as Pt-Ir, Ir-Ru and Ir-Ta showing a remarkable electrocatalytic activity and stability for the oxygen evolution reaction. However issues concerning the minimization of the catalyst loading and the maximization of the useful lifetime of a PEM electrolyser are still open challenges attracting the attention of research worldwide.
Besides the development of new electrodes, usually metal oxides, with markedly improved performance, in terms of efficiency, over the conventional PEM electrolyser systems, the major hindrance in all cases remains the maximum operating temperature, which is solely determined by the operating temperature range of the polymer electrolyte membrane (Nafion®) for which the upper limit of this range is 90-1000C. Another crucial factor that limits the tolerance, stability and mostly the lifetime of conventional PEM electrolyzer systems is the tolerance and stability of anode electrodes on carbon supports (carbon paper, carbon cloth) operating in the high potential region. It is known that when a PEM unit operates at high anodic potentials oxidation of the carbon support takes place. This project tackles both subjects through a coherent research plan under the objective of the development of novel PEM electrolysis systems operating at high temperatures up to 1800C.

Title:

BIOFUELS-2G - Demonstration of a sustainable and effective 2nd generation biofuels application in an urban enviroment

Brief description :

The core aim of the project is to study, develop and implement at pilot level advanced 2nd generation biofuels production schemes driven by local/regional public private partnerships between a Municipality, a research organization and a university, with a major mobilization of local enterprises which will provide the raw material for the fuel production.

The project will shape an integrated approach towards the implementation of a production scheme for 2nd generation biofuels, with increased sustainability (use of renewable energy sources), covering the whole production chain, from the logistics of recovery to the production of the end product. This approach will be tailored to the characteristics of the region of Thessaloniki, but easily transferable to other major urban centers in Greece, and Europe in general. The pilots will prepare the ground for large-scale implementation, which will be operated by Public-Private Partnerships. Overall the project is expected to catalyze collaboration between public and private entities in the field of waste (used oils) management and use for the production of 2nd generation biofuels.

The project can drastically improve the potential of producing 2nd generation biofuels by:

      • Adopting, integrating and implementing new policy instruments, that is the partnership between a critical mass of stakeholders.
      • Shaping innovative strategies and schemes for production which will be practically demonstrated in an urban environment.
      • Taking advantage of new opportunities and increased maturity at the institutional and entrepreneurial environment.

All the above will be integrated customized and implemented as pilots in the region of Thessaloniki in North Greece. Conditions in the region are now mature, both at policy as well as a technological level, to introduce an innovative scheme for biofuels production, in which the raw material will be provided by used food oils.

The coordinating beneficiary for this project is PSDI/CERTH, while associated beneficiaries are the laboratory of applied thermodynamics of the Aristotle University of Thessaloniki, the municipality of Thessaloniki, and the Association of restaurant owners of Thessaloniki .
