Chapter 4 Sodium-Based Battery Technologies 3.1. Sodium-Sulfur Battery Deployments At present, NGK appears to be the only significant manufacturer of the NaS technology. As of early 2020, NGK reports 560 MW/4,000 MWh of storage in more than 200 locations around the world, with some of these installations operating successfully for over a decade [3]. The applications using this technology vary significantly, addressing industrial, commercial, and residential storage needs. Specific areas of current utility include renewable stabilization, investment deferral and ancillary services, and powering microgrid and remote or island communities. As examples of the NaS deployments, large installations support the integration of renewable wind and solar assets in Japan. A 34 MW/245 MWh system supports a 51 MW wind farm in Rokkasho, Aomori, Japan and a 50 MW/300 MWh system supports a large solar array in Fukuoka, Kyusyu, Japan (Figure 4). The Fukuoka solar installation is the largest NaS system in the world and it helps balance intermittent solar energy supply and variable energy demand. While the Fukuoka installation is relatively new (2016), the Rokkasho NaS system has been a flagship project operating to balance supply and demand from intermittent wind generation successfully since 2008.

(https://www.ngk- insulators.com/en/product/nas/solutions/ancillary/index.html) For islands and microgrid applications, NGK’s NaS batteries are not only used to integrate and stabilize energy from local renewable resources (e.g, in Reunion Islands, France) but they have additionally demonstrated support for microgrid operation on Catalina Island, CA, United States. This 1 MW system provides alternative power in support of a diesel-powered energy grid when demand pushes diesel generation outside allowable operational ranges (80-100% capacity). In Italy, NGK is working with the transmission system operator Terna S.p.A. as part of an effort to integrate renewable wind energy. NaS batteries, capable of deep cycling, have been able to facilitate long-distance electricity transmission by providing a storage buffer during periods of transmission congestion (Figure 5). 8PDF Image | SODIUM-BASED BATTERY TECHNOLOGIES

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
