This week’s “Top 5” includes 75MW of energy storage contracts by PG&E under the CPUC mandate, a new Sodium-ion battery developed by a French team, the likely reconduction of the German subsidy for residential storage, a new fund led by Bill Gates which will invest in storage, and the improvement of ViZn’s battery capabilities.

Top 5

  1. « Pacific Gas and Electric Company (PG&E) this week expanded its commitment to clean energy by presenting its first 75MW of energy storage contracts to the California Public Utilities Commission for review and approval. The seven projects selected include four Lithium Ion Battery projects, two Zinc/Air Battery storage facilities and one Flywheel project, a first for PG&E. The first projects are due to come online in May of 2017.»
  1. A team from CEA and CNRS has developed a Sodium-ion battery with performances similar to that of Lithium-ion batteries in the “18650 cell” format. Due to the much higher availability of Sodium in the Earth’s crust, Sodium-ion batteries could potentially be produced at a lower cost than Lithium-ion. (in French)
  1. Germany is looking increasingly likely to extend its incentive programme for domestic energy storage systems, according to a prominent member of the country’s Green Party
  1. « Bill Gates announced his latest endeavor, the Breakthrough Energy Coalition, at the climate change summit in Paris. The new Gates fund will be fed by a group that spans more than two dozen public and private entities and will invest broadly and focus on five key areas: electricity generation and storage, transportation, industrial uses, agriculture and projects that make energy systems more efficient. »
  1. ViZn Energy Systems announced that it has enhanced the capabilities, reliability and lifetime of all its next generation MW-level flow battery systems.
