PCM briefing: A baby manikin that sweats; a salt and antifreeze TES system

Ben Welter - Thursday, August 03, 2017

Alphabet Inc.'s secretive development lab is developing a system for storing renewable energy in tanks filled with salt and antifreeze. "The system takes in energy in the form of electricity and turns it into separate streams of hot and cold air," Bloomberg reports. "The hot air heats up the salt, while the cold air cools the antifreeze, a bit like a refrigerator. ... Flip a switch and the process reverses. Hot and cold air rush toward each other, creating powerful gusts that spin a turbine and spit out electricity when the grid needs it. Salt maintains its temperature well, so the system can store energy for many hours, and even days, depending on how much you insulate the tanks."

Thermetrics baby manikinThermetrics LLC has introduced an 11-zone thermal baby manikin that features a thermally conductive carbon-epoxy shell, a “sweating skin system” and internal heater elements and temperature sensors.

PCM briefing: 'New paradigm' in pharma cold chain; opening for sales manager at Sonoco ThermoSafe

Ben Welter - Monday, July 24, 2017

GoSun solar stove• The makers of the GoSun portable stove, which uses solar energy to bake, roast or steam food at temperatures up to 290° C, have raised nearly $400,000 from investors on seedinvest.com. The stove initially used high-temperature phase change material to store the sun's energy. "We abandoned the PCM a couple years ago after we started doing testing with it," said GoSun's Matt Gillespie. He said the material did not match the performance promised by the PCM maker, degrading "significantly" after just a few cycles. The current design uses compound parabolic reflectors and a horizontal vacuum tube to convert nearly 80 percent of sunlight into usable heat. The Cincinnati company has sold 10,000 stoves online and in retail outlets such as Home Depot, REI and Cabela's. GoSun plans to use the SeedInvest funds to support continued growth.

PCM briefing: Energy storage rebate falters in California Assembly; at Los Alamos lab, it's ice ice ice ice ice ice ice baby

Ben Welter - Tuesday, July 18, 2017

• The California Assembly has essentially killed a bill to create a long-term energy storage rebate. The bill, known as SB 700, had earlier cleared the state Senate. Last week's unexpected move pushes consideration of the rebate, which would have applied to a wide range of technologies, including thermal energy storage, into next year. 

"Ice Energy and others interested in energy storage for the residential market have closely followed and supported SB 700," said Ice Energy CEO Mike Hopkins. "The Duck Curve problem is serious and storage is the solution. SB 700 would have significantly accelerated the solution so the delay is disappointing to anyone who cares about replacing fossil fuels with renewables, lowering the cost of power, and improving grid reliability. In the meantime, Ice Energy will continue to work with utilities and utilize SGIP to deliver cost effective and reliable energy storage to the residential market."
