Lithium-sulfur (Li-S) batteries, given their light weight and theoretical high capacities, are a promising alternative to conventional lithium-ion (Li-ion) batteries for large-scale energy storage systems and electric vehicles. But Li-S batteries currently suffer from poor longevity.
Now, scientists from the Gwangju Institute of Science and Technology (GIST) in Korea have discovered a new catalyst material’s ability to significantly improve lithium-sulfur battery life, giving them great commercial potential.

On Sunday, Scotland produced 106% of its electricity needs -over a 24 hour period – via wind farms. Scotland joins a select group of countries that have had peak moments (or days/months/forever) when their electricity needs comes from non-polluting renewable energy. Iceland runs completely on hydroelectric and geothermal, Costa Rica ran for 75 straight days in 2015, Portugal ran for four days, Denmark generated 140% of their demand, Germany broke 95% for a few moments and there are many other countries with wonderful clean energy achievements. With places like Hawaii aiming for 100%, Rhode Island building its first off shore wind farm and the US Department of energy readying the mainland’s grid to be able to handle 100% – we will see reports like this proliferate in the future.

It looks like Tesla is about to change the battery game – this time by installing more energy storage capacity in 2016 with SolarCity alone than all of the USA installed in 2015. In a recent filing with the SEC, it was found that Tesla foresees an almost 10X increase in sales to SolarCity for behind the meter storage.
We recognized approximately $4.9 million in revenue from SolarCity during fiscal year 2015 for sales of energy storage products governed by this master supply agreement, and anticipate recognizing approximately $44.0 million in such revenues during fiscal year 2016.
According to an analysis by GTM’s Ravi Manghan this revenue projection means Tesla expects to install approximately 116 MWh of behind the meter storage. In all of 2015, the United States installed about 76 MWh of behind the meter. Starting from a very low base, SolarCity and Tesla Energy doubled their battery installation volume last year. These were small installations at test locations for special customers, but that wall of ‘start up’ is already starting to fall. expand full story

We’ll be covering the Tesla Battery announcement later tonight but Tesla just unleashed the livestream page. Check back soon. We’ll run down the highlights here. We’re expecting Tesla to announce home and industrial battery products that allow users to store solar and lower cost, high availability electricity for use at night or during higher cost/watt time periods. The battery will be a down payment and rental fee which should more than pay for itself in electric bill savings.
There has been further speculation that, with this announcement, Tesla Motors will change its name to Tesla, Inc or Telsa Energy to note that it is an energy storage company, not just a car company. We’ll find out more soon, stay tuned.

While Tesla’s stock price gained 6% this morning after a note from Deutsche Bank, short interest on Tesla’s stock increased to 21.3% of the outstanding shares. This is the highest level of short interest on Tesla in the past 13 months. Short interest contributed greatly to the previous few surges of Tesla’s stock price. In early 2013, short interest was over 30 million shares when Tesla reported a profit. Investors started covering their short position, which created a lot of demand for Tesla’s stock.
Tesla is holding an event Thursday to announce their home energy storage products. Historically, Tesla’s stock price increases prior to an announcement and then decreases after the event. This is commonly referred to as “buying on the rumor and selling on the news”. So far, this current event is not an exception with Tesla’s stock price gaining over 20% since Elon Musk tweeted about the upcoming event to be held at Tesla’s design studio in Hawthorne.
