Flow Batteries


플로우 배터리

플로우 배터리는 kW/kWh에서 MW/MWh의 범위에서 에너지를 저장, 공급하는 것이 가능한 다용도의 매력적인 솔루션으로서 큰 가능성을 가지고 있으며, 중규모에서 대규모 전력계통에 대응하는 에너지 저장 시스템에 최적입니다. 그러나 지난 수십년간의 연구에도 불구하고 전력계통용 에너지 저장 기술이 널리 보급되는 상황으로는 발전하지 않고 있습니다. 이에 따라 한층 더 큰 효율화를 목표로 하는 전력사업자가 이용 가능한 시스템의 실현을 위해 성능 향상과 비용 절감 양측에 중점을 둔 연구개발이 현재도 계속되고 있습니다.

9:00 FEATURED PRESENTATION: Organic Aqueous Flow Batteries for Massive Electrical Energy Storage

Michael_AzizMichael J. Aziz, Ph.D., Gene and Tracy Sykes Professor of Materials and Energy Technologies, John A. Paulson School of Engineering and Applied Sciences, Harvard University

We have developed an approach to flow battery electrolytes using the aqueous redox chemistry of small, highly soluble, inexpensive organic molecules such as quinones and aza-aromatics. This new approach may enable massive electrical energy storage at greatly reduced cost.

9:40 Advancing Long Duration Flow Battery Capabilities with Coordination Chemistry

Thomas_JarviThomas D. Jarvi, Ph.D., General Manager, Energy Storage, Lockheed Martin Energy

Flow battery system architecture separates system power and energy capabilities. This separation can enable low cost and reasonable system performance if the active materials are properly designed. However, the chemistries used most commonly do not adequately take advantage of this architecture. The flow battery under development at Lockheed Martin Energy and how it overcomes several traditional flow battery shortcomings will be described.

10:10 Low-Cost and Safe Aqueous Redox Flow Batteries

Bin_LiBin Li, Ph.D., Staff Scientist, Energy & Environmental Directorate, Pacific Northwest National Laboratory (PNNL)

Redox flow batteries have attracted wide attention for long-duration, large-scale energy storage applications. We focus on current and future directions to address two of the most significant challenges in energy storage: cost and safety. A high priority is aqueous systems with low-cost and highly soluble redox chemistries. In particular, we introduce the development of aqueous inorganic and organic redox flow batteries at PNNL in the recent years.

11:15 Flow Batteries Based on Redox Targeting Reactions for High-Density Large-Scale Energy Storage

Qing_WangQing Wang, Ph.D., Associate Professor, Department of Materials Science & Engineering, National University of Singapore

In conventional batteries, active materials are coated on current collectors to form electrode sheets. On the basis of redox targeting reactions between battery materials and redox mediators, the above electrode configuration could be converted into a decoupled structure with the active materials stored in separate tanks while their charging/discharging are carried out by the redox mediators. This leads to a disruptively novel energy storage device - Redox Targeting Flow Battery.

11:45 Duration without Degradation: Delivering Multi-Hours over Multi-Decades

GJ_Ia_OGJ la O', Ph.D., Director, Electrochemical Engineering, Primus Power

Primus Power's proprietary EnergyPod® flow battery system employs only one tank of electrolyte solution and one pump (vs. two for others), a patented bromine electrode and zinc electrode and no separator (which typically need to be replaced in 5-10 years for other flow batteries) - together these lower footprint, increase lifetime and reduce cost. An overview of this innovative zinc-bromide flow battery platform will be presented.

1:35 FEATURED PRESENTATION: Composite Structures for Vanadium Redox Flow Batteries (VRFB)

Dai Gil Lee, Ph.D., Director and Professor, EEWS and Mechanical Engineering, Korea Advanced Institute of Science and Technology (KAIST)

Although vanadium redox flow batteries (VRFB) have been considered future energy conveniences, they have not been widely employed because their structures such as bipolar plates (BP), endplate (EP) or flow frames (FF) are made of either brittle graphite, weak polymers or ceramic coated stainless steel to meet the requirements of high electrical conductivity under strong acid environment such as the target values of Department of Energy (DOE), USA. To circumvent the weak characteristics and difficulty of manufacturing these structures, the carbon composite BP and the hybrid composite EP made of carbon and glass composites and the glass composite FF have been developed.

2:05 Safety Advances in Flow Batteries for Enhanced Safety and Reliability

Paul Siblerud, Vice President, Product Management, Engineering, ViZn Energy Systems, Inc.

Using advanced flow batteries provides an even greater mix of capacity, power, and long life to maximize significant cost savings. The added life benefit of flow batteries with the ability to support deep discharges multiple times per day, while simultaneously seeing 100s or 1,000s of rapid, short duration charge/discharge cycles at partial states of charge, increases the cost savings and substantial return on investment.

2:35 High-Energy Density Multiple Redox Semi-Solid Liquid Flow Battery: Redox Processes and Design Strategies

Yi-Chun_LuYi-Chun Lu, Ph.D., Assistant Professor, Electrochemical Energy and Interfaces Laboratory, Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong

We discuss design strategies to increase the energy density of redox flow batteries by going beyond the solubility limit and involving multiple active-redox, forming multiple redox semi-solid liquid flow batteries. This concept takes advantage of both highly soluble active materials in the liquid phase and high-capacity active materials in the solid phase. Using LiI electrolyte and solid S/C composite as an example, we discuss the electrochemical characteristics and the synergistic interactions of the biphase high-energy density redox flow battery.

3:05 Refreshment Break in the Exhibit Hall with Poster Viewing

3:30 The Solar Flow Battery - Opportunities for Base-Load Solar Electricity

James_McKoneJames R. McKone, Ph.D., Assistant Professor, Chemical Engineering, Department of Chemical and Petroleum Engineering, Swanson School of Engineering, University of Pittsburgh

Redox flow batteries and photovoltaics are a natural combination for providing flexible renewable power, but both suffer from high capital costs associated with manufacturing, installation, and integration. We are using the tools of photo-electrochemistry to develop a new technological approach that we call the "solar flow battery" (SFB), which converts and stores solar energy in a single monolithic device. Ongoing work using technologically relevant semiconductors and aqueous electrolytes has demonstrated the feasibility of the SFB approach and has further indicated that high roundtrip energy conversion efficiencies can be obtained from remarkably simple device architectures.

4:00 Optimizing Flow Batteries and PV for Managing Building Loads

Paul_BrookerPaul Brooker, Ph.D., Assistant Research Professor, Florida Solar Energy Center, University of Central Florida

Due to its variable nature, solar energy requires energy storage in order to maximize its utilization, particularly at high penetration levels. Flow batteries represent an ideal technology to meet these needs due to their excellent cycle lifetimes and tolerance to deep discharges. Optimizing the capacity and power of flow batteries with the amount of PV installed at the site requires balancing the building load profile with the electricity grid's needs.
