Speech Title: Self-powered 3D integrated microsystem and artificial intelligence

Abstract: Triboelectric nanogenerators (TENGs) is an emerging approach which can scavenge the mechanical energy from ambient environment based on the combination of contact electrification and electrostatic induction. It has been demonstrated to be a robust power source for self-powered microsystem, which can sense, process and respond to the environmental changes with no need for external power source. We will talk our research of self-powered 3D integrated microsystem based on TENG. In addition, the design issue can be combined with artificial intelligence for better efficiency.

Speech Title: Design and Fabrication of Electrocatalysts for Water Oxidization

Abstract: The sluggish oxygen evolution reaction (OER) is a pivotal process for renewable energy technologies, such as water splitting. The discovery of efficient, durable, and earth-abundant electrocatalysts for water oxidation is highly desirable. Here, a novel trimetallic nitride compound grown on nickel foam (CoVFeN @ NF) is demonstrated, which is an ultra-highly active OER electrocatalyst that outperforms the benchmark catalyst, RuO2, and most of the state-of-the-art 3D transition metals and their compounds. CoVFeN @ NF exhibits ultralow OER overpotentials of 212 and 264 mV at 10 and 100 mA cm−2 in 1 M KOH, respectively, together with a small Tafel slop of 34.8 mV dec−1. Structural characterization reveals that the excellent catalytic activity mainly originates from: 1) formation of oxyhydroxide species on the surface of the catalyst due to surface reconstruction and phase transition, 2) promoted oxygen evolution possibly activated by peroxo-like (O22−) species through a combined lattice-oxygen-oxidation and adsorbate escape mechanism, 3) an optimized electronic structure and local coordination environment owing to the synergistic effect of the multimetal system, and 4) greatly accelerated electron transfer as a result of nitridation. This study provides a simple approach to rationally design cost-efficient and highly catalytic multimetal compound systems as OER catalysts for electrochemical energy devices.

Speech Title:  Future Grid Optimisation Through Innovative Technologies

Abstract: Efficient and reliable transmission and distribution of electricity is a fundamental requirement for providing societies and economics with essential energy resources. The utilities in the industrialized countries are today in a period of change and agitation. Large parts of the power grid infrastructure are reaching their designed end of life time, since a large portion of the equipment was installed in the 1960s. On the other hand there is a strong political and regulatory push for more competition and lower energy prices, more energy efficiency and an increased use of renewable energy like solar, wind, biomasses and hydro. Ageing equipment, dispersed generation as well as load increase might lead to highly utilized equipment during peak load conditions. Although grid expansion will be necessary, minimising congestion on current infrastructure can make a significant contribution to the energy transition. While most grid expansion projects continue to rely on traditional technologies like constructing bigger and larger lines, the potential for proven smart grid technology to better transmission system operation has long been acknowledged. This talk will share some of the innovative technologies which are currently being investigated and implemented in order to meet future challenges and growing demand in an increasingly liberalized generation market for securing a sustainable, secure and competitive energy supply.

Speech Title:  Cost-Effective Integration of Second-Life EV Batteries with Solar PV Systems for Commercial Buildings

Abstract:  As a low cost and mature clean energy source, solar PV generation currently has a high penetration rate especially in sunshine-rich states like California. Battery energy storage systems (BESSs) are frequently incorporated with PV systems as a standard approach to buffer the volatile nature of the PV output. Household small PV and storage systems are popular products in the market. For commercial buildings, similar technology is also available, but normally featuring large centralized battery stacks and consequently high cost.

Electric vehicles (EVs) started to enjoy a booming market share since the last decade. The number of EVs on roads is enormous and keeps growing rapidly, and so is the quantity of EV batteries. It is estimated that the first huge wave of EV battery retirement in California will hit in 2025, and retired batteries will keep coming thereafter. EV batteries today, almost exclusively lithium-ion based, cost heavily in both production and recycling. Economically dealing with retired EV batteries is an important topic.

Retired EV batteries, though no longer roadworthy, still have considerable capacity for stationary applications where the requirement for energy and power density is not as stringent. As an abundant byproduct from the road, these second-life EV batteries cost much less than new products. Meanwhile, the high cost of (new) batteries in storage systems could be a major discouragement for potential clients, especially small/medium owners. Thus, developing proper technologies to bridge the supply and demand has great significance.

The aim of this research is to validate that using second-life EV batteries in BESS for PV and storage system for small/medium sized commercial buildings will reduce the overall cost over serviceable life compared to using new batteries. To achieve this, we are conducting thorough multi-scale analysis and modeling of the second-life EV battery aging process and building degradation models, accordingly developing optimized energy management strategy considering PV and load profiles, and building customized electrical and control systems for site pilot testing.
