Grid reliability is the greatest concern resulting from the current challenges facing electric utilities. The argument is that battery storage will play a significant role in improving the operating capabilities of the grid, lowering cost and ensuring high reliability, as well as deferring and reducing infrastructure investments. Utility-scale storage can be instrumental for emergency preparedness because of its ability to provide backup power, as well as grid stabilization services.

Battery Energy Storage Systems (BESSs) show promise to help renewable energy sources integration onto the grid. These systems are expected to last for a decade or more, but the actual battery degradation under different real-world conditions is still largely unknown. In this work we analyzed different types of usage for batteries similar to the ones in deployed 1MW and 2MW BESS in the Hawaiian archipelago.

With increasing mandates requiring the expansion of renewable energy on the grid, such as wind and solar, in an effort to reduce greenhouse gas emissions, there is an increasing need to manufacture and install energy storage systems, or batteries. This presentation will focus on a lifecycle assessment-based evaluation of the potential for environmental and human health impact due to the manufacturing and production of various flow battery technologies.   

Zinc and manganese dioxide are key components of primary alkaline batteries which have dominated the market for decades. They have been demonstrated as promising  energy storage materials due to the high energy-density, low cost, and outstanding safety characteristics. Transforming this non-rechargeable technology into a rechargeable system would enable it as a revolutionary low-cost solution for grid-scale energy storage. In this presentation,the development and commercialization of these systems will be presented 

Energy storage is capable of providing a number of grid benefits. This presentation focuses on the value of energy storage in CAISO when paired with solar considering the day ahead and HASP energy markets. An analysis was performed using historical solar irradiance data and historical market prices for a notional 1 MW, 4 MWh storage system combined with a 1 MW PV system considering 2200 potential locations in CAISO.

The decision to use a certain type of energy storage system for a stationary application depends largely on its economic performance. In this presentation, I will talk about the development of data-intensive bottom-up techno-economic models for large-scale energy storage system for various stationary applications. Different performance indicators, such as total investment cost, levelized cost of storage, and scale factor were developed for a wide rage of capacities. 

In this contribution we will take a closer look at battery usage in emerging fields of application such as energy arbitrage marketing, grid support on transmission and distribution level (e.g., “Grid Booster”, “Battery Assisted Fast Charging Stations”) as well as at serving combined use cases (“multi-use”). 

Lithium-ion batteries are steadily becoming a more prominent member of the modern power systems. However, they still comprise a significant cost factor despite their rapidly declining prices and improving capabilities. This talk discusses the impact of utilising more advanced, physics-based degradation models, in the context of energy trading optimisation to reduce operational cost.

System integrators, utilities, and regulatory agencies have put considerable effort into developing safety standards and recommended designs for battery energy storage systems (BESSs). However, current guidelines emphasize factory testing, commissioning, and emergency response rather than guidance for operation and maintenance. This presentation describes how the energy storage industry can shift to a predictive-monitoring and maintenance process as the next step in improving BESS operations and safety.

This talk will introduce a potential strategy to directly recycle and regenerate spent lithium-ion battery for grid applications using a “non-destructive” approach, which will lead to new electrode materials that can show the same level of performance as the native materials. Such a strategy combines fundamental understanding and process optimization for remanufacturing of energy materials. Therefore, it can potentially offer a sustainable solution for future energy storage.

End-of-life automotive batteries could be repurposed as second-life batteries (SLBs) since their 70-80% residual capacity can be adequate for stationary applications. However, it is unknown whether SLBs will be better than new batteries and whether SLBs will reduce stationary applications’ cost and carbon emissions. This talk presents the levelized cost of electricity and life-cycle carbon emissions of using SLBs and new LIBs in the US for residential and utility-level applications.
