Energy storage levels

Electric utilities can anticipate peak demands and be prepared to meet them. On the other hand, there arc short-term fluctuations in the power levels that a utility cannot anticipate but must handle quickly. Superconducting magnetic energy storage (SMES) is a technology that has potential for meeting both anticipated peak demands and those requiring quick response. 

Abstract. Newly established residential area in Vastra Hamnen (West Harbour) in the city of Malmo uses Aquifer Thermal Energy Storage (ATES) as part of the district heating and cooling system. ATES system has 5 warm and 5 cold wells that are 70-80 m deep. Cold from the nearby sea (Oresund) and water cold from heat pump is stored from winter to summer. The purpose of the system is to deliver free cooling to district cooling system at a temperature level below +6-8 °C. Operational experiences and economic aspects are discussed. 

An RFC can provide seasonal energy storage and there is near-zero self discharge. It provides high levels of storage at a reasonable cost and has the ability to store energy from multiple energy sources. 

As described earlier in this book, the dendritic architecture is perhaps one of the most pervasive topologies observed at the macro and micro-dimensional length scales (i.e. jum-m). At the nanoscale (molecular) level there are relatively few natural examples of this architecture. Most notable are probably the glycogen and amylopectin hyperbranched structures that Nature uses for energy storage.
