Title: EV Charging : Challenges and Solutions
Abstract: Electric vehicles (EVs) reduce air pollution, and are ideal for sustainable living. However, the high uptake of EVs also poses some technical challenges. These include the demand for increased levels of EV charging infrastructure, issues associated with charging infrastructure planning and offering charging services, and the grid impacts due to large-scale charging demands that compromise the stable and economic operation of the power grid. To address these technical challenges, it is crucial to deploy charging infrastructure strategically and operate charging services properly. This seminar discusses these challenges, highlighting the technical problems, and presents the solutions that have been proposed. The seminar concludes with new research directions in this area to promote further research.

Title: The Role of Building Integrated Photovoltaics in RES Energy Transition at the Global Environment
Abstract: To implement Paris agreement and keep the mean temperature increase lower than 1.5°C compared to preindustrial levels, deep decarbonization is required with the utilization of renewable energy sources. The integration of renewables in buildings is a key component in the proposed actions of WGIII and a step forward to distributed energy systems with high contribution from buildings, becoming prosumers. Since the building structure is the interface between humans and their natural environment, sustainable development requires a rethinking of the photovoltaics integration in harmony to local environmental and bioclimatic conditions. We have recently shown that the necessity of climate crisis mitigation points requires steps beyond the self-sufficient and self-consumption concepts into positive energy sharing within local communities. In this context, the SERAS concept (sufficiency, efficiency, renewables and sharing) in BIPV deployment will be presented and discussed with prioritized integration and emerging material upgrades towards carbon neutral cities.

Title: Biomass Catalytic Conversion for the Production of Liquid Bio-Fuels
Abstract: Fossil fuel is still the main source for liquid fuel production. Lignin derived from renewable biomass has the potential to replace fossil fuel. The abundance of aromatic units in lignin makes it potential to produce high-value liquid fuel. Our groups have carried out an extensive study that has been devoted to the catalytic depolymerisation and hydrodeoxygenation (HDO) of lignin for the production of hydrocarbon liquid fuels. Compared to fossil fuel components, the native molecular structure of lignin is approximate C800-900, which is far higher than the carbon chain lengths required for fuel applications (~C6-20). In this regard, lignin must be depolymerized into small molecule fragments firstly. Generally, lignin contains a high amount of ether linkages, including β-O-4, α-O-4, 4-O-5 and others. The interruption of these ether linkages is the key to decrease the molecular weight. A series of methods have been proposed to achieve this goal, such as hydrolysis, solvolysis, pyrolysis, oxidative depolymerization, reductive depolymerization and so on. Reductive depolymerization approaches are preferred to use for the production of hydrocarbon fuel precursors, for their goodness at stabilizing the intermediate products and cutting down the ratio of O/C. Wherein, selective hydrogenolysis of lignin can increase the hydrogen content and decrease the oxygen content, meanwhile lowering molecular weight by reductive cleavage of C-O-C bonds and producing a high amount of phenolic compounds. We have carried out a series of woks on hydrogenolysis of different lignin species by using Pd/C coupled with CrCl3 catalyst and acid modified Ru/C catalysts, in which the yield of phenolic monomers can be 30-42 wt%. Lignin depolymerisation products formed by reductive depolymerization still have a substantially higher oxygen content than petroleum and refinery streams, so that extensive deoxygenation and hydroprocessing are required to yield hydrocarbon fuels. Catalytic HDO is a promising approach to upgrade the lignin-derived phenolic compounds performing in a heterogeneous system. After treatment, the upgraded products achieve more hydrogen and less oxygen, rendering them with a higher heating value and better chemical stability to become hydrocarbon liquid fuels. In this field, we have proposed a series of efficient HDO catalysts, including high dispersed Ru/TiO2, Ru/SiO2-ZrO2, bimetallic catalysts and Ru/C coupled with H3BO4 catalysts etc. A high yield of hydrocarbon products from the HDO of lignin depolymerisation products enables to obtain at the temperature below 260oC.
