Of course, it&amp;#x27;s all situational so there&amp;#x27;s a place and purpose for these things as well.</text><parent_chain><item><author>Iv</author><text>As much as I love what Tesla is doing there, I&amp;#x27;d like to point out that they are not the only or even the biggest player ine the field:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Battery_storage_power_station#Largest_grid_batteries&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Battery_storage_power_station#...&lt;/a&gt;&lt;p&gt;There are other tech than lithium ion (namely, Sodium-sulphur) that seem more appropriate for applications where weight is not an issue.</text></item></parent_chain></comment><story><title>Megapack: Utility-Scale Energy Storage</title><url>https://www.tesla.com/blog/introducing-megapack-utility-scale-energy-storage</url></story>
