One Thermal Storage System, On the Rocks

By getting their ice after hours – like the rest of us – Google will be saving money and decreasing pressure on Taiwan’s electrical grid. Can you say the same?

Late last week, Data Center Knowledge reported on (and Grist picked up on) Google’s latest energy-savvy move: cooling their soon-to-open data center in Taiwan with a thermal storage system, which will run air conditioning systems at night – when the power rates are cheaper – to chill or freeze large batches of liquid coolant or ice that can then be used to cool the buildings during the day – when typically high demand on the electricity grid bumps up prices.

“I’m […] happy to be able to confirm that this will be one of the most efficient and environmentally friendly data centers in Asia,” says Google Taiwan’s managing director, according to Data Center Knowledge.

Google isn’t the only one wanting to jump on the thermal storage boat. A quick search (thermal energy storage) on Knowledge Mosaic’s Laws, Rules and Agency Materials page brings up a variety of materials touching on the topic:

  • A legislative bill (H.R. 4096) referred to House committee that would provide an energy investment credit for energy storage property (such as thermal energy storage systems) connected to the grid
  • A GAO report examining the DOE’s Advanced Research Projects Agency – Energy (ARPA-E), who awarded funding to several advanced thermal storage projects last year
  • An SEC administrative proceeding revoking the registration of Thermal Energy Storage, Inc’s securities
  • A section of the U.S. Code (42 USC Sec. 17171) calling for the Secretary of Energy to establish a program of R&D “to provide lower cost and more viable thermal energy storage technologies to enable the shifting of electric power loads on demand and extend the operating time of concentrating solar power electric generating plants”
  • A USPTO press release announcing National Inventors Hall of Fame 2012 Inductees, including Mária Telkes (1900-1995) for her work on solar thermal storage systems
