Presentation title: Development Status of Green Ammonia Co-firing technology and Demonstrations Strategy in Korea Abstract: The international community has announced Nationally Determined Contributions (NDC) with the aim of achieving carbon neutrality and actively engaging 137 countries in response to the climate change crisis. The South Korean government also unveiled its NDC in 2021, targeting a 40% reduction of CO2 emission compared to 2018 levels. Accordingly, the recent 10th Basic Plan for Electricity Supply and Demand (‘23.1) outlines a gradual reduction in the proportion of coal-fired and LNG power generation within domestic electricity production, with a projected share of 14.4% for coal and 9.3% for LNG by 2036. To replace these reductions, the government has set a goal to increase the production of hydrogen (H2)/ammonia (NH3)-based power generation to 7.1% by 2036. Incorporating ammonia co-firing into existing coal-fired power plants is considered a key element in achieving carbon-neutrality, low-carbon power generation. In pursuit of this goal, the South Korean government is focusing on the development of ammonia co-firing technology and aims to achieve a 20% co-firing demonstration in four plants (Pulverized coal: 2 units, Fluidized bed: 2 units) by 2027. To achieve this target, technological development and infrastructure construction are needed to address various technical aspects (combustion, performance, system, and environmental) associated with ammonia co-firing in existing boilers. Additionally, policy improvements related to laws and regulations for ammonia, the development of commercialization models, and the strategies for overseas market entry are necessary. After the successful ammonia 20% co-firing demonstration, the South Korean government has plans to expand ammonia 20% co-firing to more power plants and is considering the application of high-concentration (50%) ammonia co-firing. Accomplishing the ammonia co-firing demonstration is crucial for the future of South Korea, and it requires collaboration among various institutions to realize the carbon neutrality goals of both South Korea and the global community.

Presentation title: Development of a 2 MWe Supercritical Oxy Combustion CFBC for Biomass.
Abstract: The part of the future energy plant project performed in 2015 – 2021, this team developed a 2MWe CFBC with oxy combustion. The design includes the water circuit to attain 235bara and 450℃ condition, the combustor condition to handle biomass and solid recycled fuel. The plant was repowered from the old 2MWe 45bara 450℃ boiler, thus utilization of existing 45bara steam generator was essential. In order to produce 45arar steam for the existing generator the final fluid from the super heater circuit was de pressurized and the convection pass was re-designed to re-heat the final steam. The design was in house and fabrication of the boiler and the construction were by the local contractors. The key issue of the project was how to down scale the supercritical boiler to 2MWe. This design minimized parts and accessories of the conventional supercritical CFBCs.
The operation of the boiler included multiple fuel combustion, those were bituminous coal, solid recycled fuel and biomass. Combustion efficiency of biomass was over 99%. Also the oxy combustion condition was tested by mixing pure oxygen with recycled flue gas. The duration of the operation was over 200 hours. During oxy combustion over 90% of CO2 in flue gas was attained.

Presentation title: Defect electrocatalysis
Abstract: It is of great importance to construct active site with high intrinsic activity for a certain reaction. Followed by achieving high dense of such active sites into a catalyst, the overall activity can be significantly promoted. Defects on carbons can not only serve as active sites, especially by a series of modification for electronic and molecular structures, with high intrinsic activity, but also can provide a large number of sites for trapping various atomic metal species, achieving high density of active sites. In 2015, we firstly initiated the concept of defect mechanism for ORR, then expanded it to hydrogen evolution (HER) and oxygen evolution reactions (OER), gradually establishing the new research field of defect electrocatalysis in the following years. The defect can provide enormous advantages for trapping atomic metals such as Ni, Co, Fe as examples with different coordination, e.g. defective materials, to activate chemical reactions such as oxygen reduction, hydrogen and oxygen evolution reactions. The numbers of the active sites can be controlled by the precisely control of defect synthesis. This new strategy provides opportunities to develop catalysts with high activity and high stability. Accordingly, it should be a future research focus for next generation catalysts that the design of active site with high intrinsic activity and assembly of the active sites with precisely controllable numbers into a catalyst.

Presentation title: Biomass to Syngas and Chemicals by Electric Induction Heating
Abstract: Converting biomass to syngas (or hydrogen) and chemicals is promising for carbon neutrality especially when the whole process is heated by green electricity. Among various electric heating methods, electromagnetic induction heating (IH) is of high efficiency and has been used in a few industries, such as the metallurgical industry, and in household, in the form of induction cookers, but has not been used notably in biomass conversion to syngas (or hydrogen) and chemicals. This talk presents our recent studies on biomass conversion based on IH, including (1) pyrolyzing biomass to syngas in a two-stage under inert and steam atmospheres [1] and (2) reacting pyrolysis-derived biochar with calcium oxide (CaO) for calcium carbide (CaC2) via the newly observed char self-heating by high frequency induction [2,3].
For the biomass conversion, it is found that (1) the heat generation rate in the two-stage reactor by the induction is very high, reaching to ³1000 °C in less than 1 min; (2) more than 94.8% tar can be converted to coke and gas in the second stage in 0.5 s; (3) steam can greatly reduce the tar, bio-char and coke yields and increase gas yield to 0.86 L/g-CS H2 and 0.71 L/g-CS CO. These observations warrant stable operation at larger scales and can be extended to a new route for green H2 production.
For the CaC2 production from bio-char, it is found that (1) coal chars and bio-chars, such as walnut shell-chars (WS-char), prepared from pyrolysis at temperatures ³800 °C can be heated by induction of 400 kHz; (2) the IH behavior of chars is determined by their electrical conductivity that is further related to the structure parameters characterized by XRD and Raman; (3) pellets prepared from WS-char and CaO can also be heated by induction to produce CaC2 through high temperature solid-state reaction.

Presentation title: Nanoporous carbon materials for adsorptive CO2 capture
Abstract: Decarbonization is the process of reducing or eliminating carbon dioxide (CO2) emissions from various sources, which is of importance for a sustainable future. Adsorptive separation is one of the attractive technologies, which shows easy regeneration and high cycle stability, and thus reduced energy penalties and cost.[1,2] In this talk, the recent progress regarding the innovation of porous carbon adsorbents to the case study for CO2 separation practices will be included. In the adsorbent aspects, the key intrinsic properties such as pore structure, surface chemistry, preferable adsorption sites, and other structural features that would affect CO2 capture capacity, selectivity, and recyclability will be first discussed. Then, their performances from case to case will be studied and compared, including uptake and selectivity under dry and humid CO2 streams with different concentrations. Finally, a brief outlook on remaining challenges and potential directions for future low-concentration CO2 removal will be given. We hope that this report could inspire interdisciplinary activities between the design and modification of adsorbents and the practical CO2 separation or removal technologies.

Presentation title: Operando Characterization of Energy Materials Based on Electron Spin
Abstract: A deep understanding of energy materials’ evolution during operation plays a crucial role in optimizing their structures for improved performance. In almost all the electrochemical processes for energy storage and conversion, electron transfer is the essential step via which the spin of electrons will provide valuable information for an insight into the fundamental mechanism. In this regard, two types of operando characterization techniques, namely magnetometry and electron spin resonance, are developed based on electron spin. By using these techniques, the traditionally-believed inactive transition metals have been revealed to store charges at the interface with the solid electrolyte interface and the strong interaction between hard carbon and sodium ions has been confirmed. The operando characterizations developed here may be of paramount importance for developing better materials for energy storage.

Presentation title: Gas and Energy Storage Using Metal-Organic Frameworks
Abstract: Metal-organic frameworks (MOFs) are an emerging field with a rapid growth of the number of publications over the past 10 years. MOFs have drawn special attention because of their potential in many areas including separation, catalysis, and gas storage and energy storage. In this workshop, I will present advancements in gas and energy storage using MOFs. Isostructural [M2(DOBDC)(EG)2] (M=Mg, Co, Ni) frameworks are first synthesized by controlling the pH* in the reaction medium. Coordinated ethylene glycols form a hexagonal OH cluster, which works as a template to grow single-crystals with high crystallinity. After the liberation of solvated molecules, [M2(DOBDC)] shows notably higher surface areas than the reported values and completely different CO2 and CO separation properties depending on the kinds of unsaturated metal. To reveal the role of unsaturated metal sites, CO2 and CO adsorption sites are unequivocally determined by single-crystal X-ray diffraction analysis. This observation provides new insight into the synthesis of novel functional materials with high CO2/CO separation performance. Our exploration extends beyond gas storage; we have ventured into leveraging MOFs as electrode materials. Through laser pyrolysis of [Ni2(DOBDC)(EG)2], we rapidly engineer precisely controlled Ni nanoparticles/carbon. The quenching rate significantly impacts the structural disorder, size, and homogeneity of these nanoparticles. Remarkably, Ni (5.5nm)@carbon demonstrates an exceptional specific capacitance of 925 F/g, coupled with unparalleled cyclic stability, attributed to the formation of redox-active α-Ni(OH)2. We believe that the laser-based electrode synthesis have a great deal of potential as energy storage electrodes.

Presentation title: New strategies to improve performance for sodium metal batteries
Abstract: Sodium–metal batteries (SMBs) are a sustainable, appealing, low–cost alternative to lithium metal batteries due to the high theoretical capacity (1,165 mA h g−1) and abundance of sodium. However, the low compatibility of the electrolyte with the anode and cathode leads to unstable electrode–electrolyte interphases. Here we introduce the concept of using salt as a diluent, which enables the use of a single non–flammable solvent (trimethyl phosphate). By adding sodium nitrate (NaNO3) as a model diluent, we design a 1.1 M NaFSI–NaNO3–trimethyl phosphate (TMP) electrolyte that construct a stable interface with SMBs anode. The carbonate–based electrolyte reacts incessantly with Na(Ni0.3Fe0.4Mn0.3)O2 (NFM) and Na metal due to the existence of free solvent molecules. This leads to severe NFM uncontrollable dendritic sodium development and cracking. This renders them unapplicable for long–stability of SMBs. In the TMP–based localized high–concentration electrolyte (LHCE), like the NaFSI salt, the eutectic NaNO3 diluent molecule strongly interacts with TMP. It subtly substitutions the TMP site in the Na+ primary solvation shell. This solvation structure facilities the formation of a compact SEI on both the cathode and anode derived from the decomposition of electrolyte salts. Such an electrolyte design would therefore enable long–life SMBs. In addition, the use of a single non–flammable solvent such as TMP can improves the safety of the cells. The work demonstrates a promising approach the development of safe, sustainable, high–performance, low–cost SMBs.
Ambient–temperature sodium−sulfur (Na–S) batteries are a sustainable, appealing, and low–cost alternative to lithium–ion batteries due to their high energy of 1274 W h kg−1 and material abundance. However, their practical application is hampered by Na loss due to side reactions with the electrolyte, Na polysulfide (NaPS) shuttling, and dendrite growth. Here, we present effective solutions in terms of both electrolytes and materials. Frist, we demonstrate that a solid–electrolyte interphase rich in inorganic components can be realized at both the sulfur cathode and the Na anode by tweaking the solvation structure of the electrolyte. This transforms the sulfur redox process from conventional dissolution−precipitation chemistry into a quasi–solid–state reaction, which eliminates NaPS shuttling and facilitates dendrite–free Na–metal plating and stripping. Second, we report an intercalation–conversion hybrid positive electrode material by coupling the intercalation–type catalyst, MoTe2, with the conversion–type active material, sulfur. In addition, MoTe2 nanosheets vertically–grown on graphene offer abundant active catalytic sites, further boosting the catalytic activity for sulfur redox.

Presentation title: Synthesizing High-Performance Porous Hard Carbon Anodes for Potassium-Ion Batteries Directly from Black Liquor and Deinking Sludge
Abstract: Porous hard carbon anodes, with large interlayer space and high adsorption ability, can offer much better cycle stability and higher discharge capacity for potassium-ion batteries compared to commercial graphite anodes. However, most commercial hard carbon is synthesized from relatively expensive high-molecular polymer. In this study, papermaking wastes were utilized as precursors for producing hard carbons and pore-enlarging agent, respectively. Specifically, after thorough mixing through ball milling, black liquor solids and pore-enlarging agent were utilized to produce the porous hard carbon anode via the co-pyrolysis method. The pore-enlarging agent consists of chlorides derived from deinking sludge. The results show that direct pyrolysis of black liquor can produce hard carbons efficiently, eliminating the need to extract lignin from black liquor. Moreover, it is shown that pore-enlarging agent derived from deinking sludge is able to enlarge much portion of pores on hard carbons, resulting in abundant mesopores. Electrochemical tests demonstrate that the synthesized porous hard carbon anodes can achieve highest specific capacity of 303.5 mAh g-1 at 100 mA g-1 using a 1.0 M potassium hexafluorophosphate electrolyte in a mixture of diethyl carbonate and ethylene carbonate. Additionally, the synthesized porous hard carbon anodes exhibit low average capacity decay per cycle of 0.06% at 100 mA g-1 when tested with a 1.0 M potassium bis(fluorosulfonyl)imide electrolyte in the same solvent mixture after 500 cycles. Therefore, recycling black liquor and deinking sludge to produce porous hard carbon anodes for potassium-ion batteries is a promising approach for environmental and energy sustainability.

Presentation title: The mechanism of on-line electrochemical upgrading of biomass pyrolysis based on proton ceramic membrane
Abstract: Electrochemical hydrogenation can effectively improve the physicochemical properties and storage stability of bio-oil, it has the advantages of mild reaction conditions and no need of external hydrogenation source. In view of the problem that traditional low temperature liquid phase electrochemical hydrogenation can only deal with raw bio-oil water phase components, and the product needs to be separated from liquid electrolyte, so it is difficult to run continuously. A new idea of in situ medium-temperature gas-solid phase biomass fast pyrolysis connected with electrochemical hydrogenation based on intermediate temperature proton ceramic membrane electrolyzer cell (IT-PCMEC) is proposed. In this work, aiming at two key problems as “the ceramic membrane electrolysis pool proton transport coupling in situ biomass pyrolysis gas electrochemical reaction mechanism” and “the collaborative optimization of biomass fast pyrolysis and in situ electrochemical upgrading under multi-field conditions”, the diffusion and hydrogenation mechanisms of biomass pyrolysis gas at the cathode interface was investigated. Revealing the internal proton transport mechanism of the ceramic membrane electrolysis cell. Explaining the synergistic mechanism of heat-mass transfer during the electrochemical hydrogenation of biomass pyrolysis gas under multifactorial influences. Ultimately, an optimized coupling mechanism for rapid pyrolysis of biomass and electrochemical hydrogenation of protic ceramic membranes was developed.

Presentation title: Dry auto-thermal reforming of CH4 for syngas production directly from flue gas with low CO2
Abstract: The climate change crisis has been warned by carious institutions, and today, disasters caused by such climate change are occurring around the world. Therefore, countries around the world are making various efforts to solve this climate change crisis, and ways to reduce greenhouse gases are recognized as one of them. CCU technology is a technology that converts carbon dioxide and is receiving high attention as a key technology for reducing greenhouse gases. However, conventional dry reforming of methane (DRM) utilizes CO2 at high concentrations, so a CO2 capture process is included, resulting in additional CO2 emissions. In addition, since DRM involves a strong endothermic reaction, the temperature of the catalyst is lowered during the reaction, causing problems such as coke generation, catalyst deactivation and reactor clogging. In order to solve the problem of DRM with CO2 capture, this study developed a dry auto-thermal reforming of methane (DARM) that produces syngas by directly reacting CH4 and CO2 gas with low oxygen concentration and without a carbon capture device.

Presentation title: Engineering approaches to co-combustion of carbon-free fuels to coal power generation systems – Experimental & process simulation studies
Abstract: The co-combustion of low-carbon or carbon-free fuels such as biomass, ammonia, and hydrogen in existing thermal power generation plants is one of the most efficient and economical ways to reduce carbon emissions. This paper introduces engineering approaches to the co-combustion of these fuels for coal power generation plants, which are categorized into three parts: (1) Co-combustion methods for the boiler, (2) Evaluation of thermal performance for various co-firing ratios, and (3) Combustion optimization through pilot-scale experiments. Part (1) introduces various methods applicable to existing plants and discusses their pros and cons. Part (2) includes process simulation studies for these methods and various co-firing ratios aimed at understanding the effects of partially replacing the fuel on the thermal performance of the plants.

Presentation title: Machine Learning-based Guided Synthesis of Engineered Biochar for High-performance CO2 Capture
Abstract: Biomass waste-derived engineered biochar for CO2 capture presents a viable route for climate change mitigation and sustainable waste management. However, traditional synthesis approaches for developing engineered biochar materials with high-performance CO2 capture performance are both time- and labor-intensive, and the underlying mechanism for CO2 adsorption is still challenging to design textural properties and functional groups of engineered biochar. Therefore, we first applied machine learning to systematically map CO2 adsorption as a function of the textural and compositional properties of engineered biochar materials and adsorption parameters, and then devised an active learning strategy to guide and expedite their synthesis with improved CO2 adsorption capacities. Finally, we demonstrated a data-driven workflow to accelerate the development of high-performance engineered biochar with enhanced CO2 uptake and broader applications as functional materials.

Presentation title: Production and Utilization of Green Ammonia for Decarbonization
Abstract: Green ammonia, recognized as a carbon-free chemical, is drawing substantial interest as both a hydrogen carrier and a carbon-neutral fuel. It boasts a hydrogen content of 17.6 wt% and a volumetric energy density of 3.2 kWh/L at a mere 8 bar pressure. Remarkably, it remains liquid at ambient temperature under 10 bar or at -33°C at atmospheric pressure, enabling it to store 1.7 times more hydrogen than the equivalent volume of liquid hydrogen at -253°C. Globally, the annual production of ammonia surpasses 180 million tons, with over 20 million tons transported by sea. This underscores the well-established land and maritime infrastructure for ammonia transport, highlighting its pivotal role in facilitating the trade of green hydrogen and fostering a carbon-neutral society. Its advantageous volumetric hydrogen content and energy density, when compared to liquid hydrogen, further emphasize its importance. Additionally, the requisite infrastructure for ammonia’s storage and transport is already in place. To seamlessly integrate green ammonia into the current energy frameworks, it is imperative to focus on the development of technologies that allow for its cost-effective production, decomposition, and utilization. This presentation will delineate the Korea Institute of Energy Research (KIER)’s ongoing achievements and forward-looking views on devising economical methods for the production and application of green ammonia.

Presentation title: Interface Engineering and Structure Design of High-capacity Electrode Materials for High Energy Density Lithium Ion Batteries
Abstract: Lithium-ion batteries (LIBs) have been widely used as grid-level energy storage systems to power electric vehicles, hybrid electric vehicles, and portable electronic devices. However, it is a big challenge to develop high-capacity electrode materials with large energy storage and ultrafast charging capability simultaneously due to the sluggish charge carrier transport in bulk materials and fragments of active materials. To address this issue, composite electrodes of SnO2 nanodots and Sn nanoclusters embedded in hollow porous carbon nanofibers (denoted as SnO2@HPCNFs and Sn@HPCNFs) were respectively constructed programmatically for customized LIBs. Highly interconnected carbon nanofiber networks served as fast electron transport pathways. Additionally, the hierarchical hollow and porous structure facilitated rapid Li-ion diffusion and alleviated the volume expansion of Sn and SnO2. SnO2@HPCNFs delivered a remarkably high capacity of 899.3 mA h g-1 at 0.1 A g-1 due to enhanced Li adsorption and high ionic diffusivity. Meanwhile, Sn@HPCNFs displayed fast charging capability and superior high rate performance of 238.8 mA h g-1 at 5 A g-1 (∼10 C) due to the synergetic effect of enhanced Li-ion storage in the bulk pores of Sn and improved electronic conductivity. a mechanically reinforced localized structure is designed for carbon-coated Si nanoparticles (C@Si) via elongated TiO2 nanotubes networks toward stabilizing Si electrode via alleviating mechanical strain and stabilizing the SEI layer. Benefited from the rational localized structure design, the carbon-coated Si nanoparticles/TiO2 nanotubes composited electrode (C@Si/TiNT) exhibits an ideal electrode thickness swelling, which is lower than 1% after the first cycle and increases to about 6.6% even after 1600 cycles. While for traditional C@Si/carbon nanotube composited electrode, the initial swelling ratio is about 16.7% and reaches ≈190% after 1600 cycles. As a result, the C@Si/TiNT electrode exhibits an outstanding capacity of 1510 mAh g-1 at 0.1 A g-1 with high rate capability and long-time cycling performance with 95% capacity retention after 1600 cycles. The rational design on mechanically reinforced localized structure for silicon electrode will provide a versatile platform to solve the current bottlenecks for other alloyed-type electrode materials with large volume expansion toward practical applications.

Title: Upgrading of bio-oil: From biofuel to biocarbon
Abstract: Bio-oil is a condensable liquid from pyrolysis of biomass, which is regarded as the feedstock for the production of chemicals and biofuels. Bio-oil itself is a mixture of organic compounds, which can be converted into value-added chemicals and biofuels via the process such as distillation, acid-catalysis and/or hydrogenation. In addition, bio-oil could also be converted into biofuels via hydrotreatment. In these processes, a common issue is the formation of coke from the polymerization or cracking of the organics in bio-oil, which is a bottle-neck issue in the utilization of bio-oil. Based on our previous work on the understanding of the mechanism for the polymerization of the main organic components in bio-oil, we propose that bio-oil can also be a feedstock for the production of carbon materials. A process for the polymerization of the organics in bio-oil on the surface of biochar with the aid of the polymerization agent such as furfural is proposed, via which a high yield of carbon material could be produced. This approach expands the application of bio-oil as the feedstock for the production of not only chemicals and biofuels, but also carbon materials.
