It may actually happen a year or two earlier, at least for the industry leaders, with everyone else following soon after.&lt;p&gt;Personally, with the rise of all-electric vehicles and solar roofs&amp;#x2F;home battery systems (for which Li-Ion is much more convenient), I&amp;#x27;m quite skeptical that other technologies will be able to beat Li-Ion in being used by power companies. The ecosystem and economies of scale will greatly favor Li-Ion, for now, and whatever new tech the battery makers decide to adopt later on (like solid state batteries).</text><parent_chain></parent_chain></comment><story><title>Canada Battery Maker Says Flow Storage Costs to Tumble by Half</title><url>https://www.bloomberg.com/news/articles/2018-12-24/canada-battery-maker-says-flow-storage-costs-to-tumble-by-half</url></story>
