Speech Title: Electricity from Renewable Energy Sources and Global Sustainability Goals
Abstract: A common misconception for the transition to renewables is that the amount of electric energy supplied from wind and solar sources may be increased without limit to achieve the goal of decarbonizing the electricity generation industry. However, the production of electricity from wind energy is intermittent, the production from solar irradiance is periodically variable and, oftentimes, the supply is not sufficient to satisfy the demand. The installation of large numbers of solar and wind units and the generation of a higher fraction of the total annual energy from renewables in a region meets a barrier during periods when the power generated by the renewable sources is high and exceeds the demand of the electricity grid. At present, this limit first appears when solar and wind units produce 25-30% of the annually consumed electric energy. Solutions to this problem for a higher penetration of renewables in the marketplace include large scale energy storage. This presentation examines the causes and effects of the U-shaped demand curve (the duck curve). The analysis is based on hourly data for the supply of electricity from PV cells and wind turbines and the regional demand for energy and power. The hourly energy demand is analyzed and balanced with the supply of energy. Energy storage systems ensure that sufficient energy is available to the consumers at all levels of the demand. Hourly data are presented for the demand, the supply, and the storage system capacity for the entire electricity grid of Texas (ERCOT). Results are presented on the hourly, daily, and seasonal storage requirements; on the energy production and consumption for the wider market penetration of wind and solar units within a region; and the effect of the substitution of fossil fuels with renewables on the price of electricity in a region; and the effect on the goals for a sustainable future.

Speech Title: Synergistic Enhancements of Performance for Non-Aqueous Redox Flow Batteries
Abstract: Compared with the conventional aqueous electrolyte, the non-aqueous Deep Eutectic Solvent (DES) has a wider electrochemical window, simple preparation process, low vapor pressure and low cost, hence it has been used as electrolyte for redox flow batteries. But the high viscosity of DES will cause inferior transport property, resulting in lower performance. To address this issue, external fields are applied to the DES-electrolyte redox flow battery. The changes on physical and electrochemical properties and impedance of DES electrolyte are comprehensively studied under the effect of temperature, magnetic field and supersonic field, respectively, and the underlying mechanisms are explored. The fields-synergy is analyzed and the optimized multi-fields are applied to a DES electrolyte redox flow battery, leading to a cell performance enhancement up to 77%.

Speech Title: Influence of coagulation behavior and floc properties on membrane fouling: The role of different Al species
Abstract: Al salt coagulant has the characteristics of easy availability, low price and well performance. It has been widely used in the coagulation-ultrafiltration hybrid (CUF) process to improve the removal efficiency of organic matters and alleviate membrane fouling. After the Al salt coagulant is put into water, a series of Al hydroxy complexes are formed by hydrolysis polymerization, including Ala (mononuclear species), Alb (medium polymer species), and Alc (higher polymers and colloidal species). In this study, the Al salt coagulant with Ala, Alb and Alc as the main forms was obtained by optimizing the synthesis parameters, and the coagulation mechanism of different water quality types was further studied. Meanwhile, the mechanism of membrane fouling was studied combined with the difference of floc characteristics, and the optimum Al species for the CUF process was clarified. The results show that the main coagulation mechanism of three Al species was significantly different as water quality and coagulation conditions changed. Under the raw water pH condition, the coagulation mechanism of Ala, Alb and Alc in HA simulated water was charge neutralization, adsorption bridging and sweep, respectively; which in actual water was hydrolytic precipitation, adsorption charge neutralization and bridging, sweep and charge neutralization, respectively. Moreover, Ala mainly relied on hydrolytic precipitation and charge neutralization in dye wastewater treatment, while Alb and Alc mostly combined with dye molecules through sweep and adsorption bridging. It was also found that under the raw water pH condition, the flocs generated by Ala with larger floc size and loose structure in HA simulated water treatment, resulting in loose cake layer to improve membrane fouling. Moreover, the floc size growth of Alb was obvious at the dosage of 6 mg L-1 in actual water, which reduced the entry of small particles into the membrane pores, leading to the smaller total membrane resistance. The membrane fouling mechanism was changed from pore plugging to cake layer as the dosage increased. The loose cake layer could effectively alleviate membrane fouling by reducing the amount of organic matter in membrane pores.

Speech Title: Is technology of flue gas CO2 fixation by microalgae a carbon-negative technology?
Abstract: The technology of flue gas CO2 fixation by microalgae is highly attractive in the era of CO2 neutrality. However, CO2 emission along the whole process has yet to be sufficiently evaluated. Here, a life-cycle assessment was performed to evaluate the energy conversion characteristics and environmental impacts of flue gas CO2 fixation from coal-fired power plant (case1) and coal chemical plant (case2) by microalgae. The results show that total energy consumption and CO2 gas emissions for case1 are 27.5-38.0 MJ/kg microalgae power (MP) and 5.7-7.7 kg CO2 equiv /kg MP, respectively, which are lower than that for case2 (122.5-181.3 MJ/kg MP and 32.7-48.6 kg CO2 equiv /kg MP). The CO2 gas aeration rate and microalgae growth rate are the two most sensitive parameters for the energy conversion and net CO2 emission. Therefore, increasing the CO2 aeration efficiency and microalgae growth rate are key to advance the technology of flue gas CO2 fixation by microalgae which will contribute to carbon naturality.

Speech Title: Performance analysis of a solar-assisted regenerative vacuum membrane desalination system
Abstract: According to the latest reports from the United Nations, only 74% of the global population has access to clean and safe-to-drink fresh water. Most of these communities are located in areas with favorable solar radiation levels. Considering the futuristic concerns about energy supply as well, it is essential to conceptualize reliable and cost-effective solar power-driven desalination systems for small and remote communities. Among the different water desalination technologies, vacuum membrane desalination (VMD) has favorable heat and mass transfer characteristics, as well as lower energy consumption. This presentation will cover a comprehensive techno-economic analysis of a solar-assisted VMD system with brine recirculation, operated on the Northern coast of Egypt, where freshwater resources are scarce and solar radiation levels are immense. The process of modeling the VMD system and dynamic simulation of its annual performance in TRNSYS will be discussed in detail. Our results for a 0.2 solar fraction system indicate an annual average gained output ratio (GOR) and specific thermal energy consumption (STEC) of 2.51 and 133.5 kWh/m3, with levelized cost of water (LCOW) and payback period (PBP) of 14.7 USD/m3 and 1.53 years, respectively. The presentation will also discuss the impact of the sizing of different system components on its solar fraction, GOR, STEC, PBP, and LCOW.

Speech Title: Machine Learning-Assisted Exploration for Carbon Neutrality Potential in Wastewater Treatment Plant
Abstract: In the context of advocating carbon neutrality, there are new requirements for sustainable management of municipal sludge (MS) in wastewater treatment plant. Hydrothermal carbonization (HTC) technology offers an efficient and economical solution by converting high-moisture MS into valuable products (i.e., hydrochar) at a relatively low temperature and autogenous saturation pressure without drying pretreatment. However, so far there is still a lack of overall assessment in terms of carbon neutrality potential of MS recycling via HTC. With the accumulation of experimental data on HTC reactions of MS, emerging methods of machine learn-ing (ML) are qualified to elaborate the multivariate relationships by building data-driven prediction models and uncover the correlations between factors and tar-gets. The study distinguished the properties of common types of MSs and con-structed the ML models for predicting hydrochar HHV, carbon recovery and en-ergy recovery, which was applied to further screen out which types of MS would be appropriate or inappropriate for using HTC treatment to maximize the hydro-char quality as well as carbon and energy recovery.

Speech Title: Fate of Organic Fertilizers in Aquatic Ecosystems: Influence of Oxygen and Sunlight
Abstract: Iron is an essential micronutrient for plants and a limiting factor in plant growth. Although iron is the most abundant nutrient in almost all soils, iron deficiencies frequently occur in crops as a result of their low solubility in soil and the high sensitivity of plants to iron chlorosis. However, the iron addition is not a good solution if its permanence in soluble form in soil is not ensured. This is achieved by applying organic fertilizers, which are highly stabile iron chelates, such as EDDHA, DTPA and EDTA.
Nevertheless, these organic fertilizers applied to agriculture may not be completely absorbed by plants and therefore arrive to surface or groundwater. So far, their reactivity in the aquatic environment has not been deeply studied. In the field of wastewater treatment, some iron chelates may potentially be used in photo-Fenton treatment to avoid the iron precipitation at neutral pH. In the literature related to this research area, there are evidences of the reactivity of iron chelates with UV radiation and oxygen, and how these processes could potentially lead to the generation of reactive oxygen species (ROS). These species could have significant environmental implications if they are also formed in aquatic ecosystems.
This study shows the reactivity of some widely used organic fertilizers in the aquatic environment and the mainly involved reaction mechanisms. This includes information about ROS formation because of the interactions between these agricultural products and both sunlight and dissolved oxygen in aquatic systems.
