ICEF 3rd Annual Meeting Summary: Concurrent Session - Energy Storage
Session background and objectives
Long-term Energy storage technologies can contribute to the stabilization of energy system through peak shaving, buffering seasonal variation and providing energy supply in the event of a disaster. To accelerate introduction of energy storage technologies, improvement of their economic viability is an important factor. In this session, current state and pending issues (both technological and policy) which faces energy storage technologies that are able to store energy over a long period of time will be discussed.

Energy storage systems integrated with renewable energy generation have the ability to provide resiliency, keeping critical electrical loads powered in a disaster situation, while also delivering valuable services to the electric grid during normal operation. To illustrate how these systems can be deployed and the economics opportunities they can be designed to address, two resilient solar photovoltaic and battery storage projects installed in the United States will be presented – a multi-megawatt utility-scale installation and a small building-level installation. Some of the current challenges to deploying renewable resilient power systems will also be discussed.

General Manager, Business Development Department, Energy System Division, Sumitomo Electric Industries, Ltd.
Sumitomo Electric Industries, Ltd. (SEI) has been the leading company in Flow Battery Systems development and manufacturing. SEI’s Flow Battery Systems offer long lifetime and unlimited charge/discharge cycle-life, due to negligible degradation of its electrolyte. The characteristic makes them suitable to bundle multiple energy service applications together, such as mitigation of short duration fluctuation of renewable sources and long duration energy shift, etc. Considering such advantages, flow battery is expected to be an important technology for stabilizing power grids. This presentation introduces the advantages of SEI’s Flow Battery Systems and recent projects including micro-grid applications.

Energy Storage Offers Value in Off-Grid Applications
Energy Storage Systems (ESS) have rapidly developed in 5 years. Today, the entire spectrum (Chemical, Thermal, Cryogenics, Ultra-Capacitors, PCMs, Flywheels, Power-to-Gas and Compressed Air) is commercially available. While the unit cost of ESS (in both power and energy terms) will remain higher than grid supply, its “usefulness and economic value” in “smaller unitized” off-grid applications is becoming more attractive. Increased efficient utilization, energy access/rural development policies, Renewable DERs and LVDC, allow for this ESS cost premium to be narrowed. The author will discuss this aspect in conjunction with the work being done in Cigre, IEEE, IEC, LVDC committees.

Toshiba has developed H20ne™，a Hydrogen-based autonomous energy supply system towards off-grid local facilities and remote communities. That can supply stable power and hot water corresponding to the demand all around year using only renewable energy without carbon emission despite weather, day and night, which was realized by hybrid energy system comprised of Hydrogen power storage and battery. The H20ne™ will be also applicable to shelter in which several hundred evacuees should stay for weeks. In the session, the system configuration, practical installation examples and case study towards small community will be signified.
