PCM briefing: Siemens touts packed-bed thermal storage breakthrough; TSCA's impact on chemical importers

Ben Welter - Thursday, October 20, 2016

Siemens says its recently launched packed-bed thermal storage concept for wind power could deliver energy at well below 0.10 euros per kilowatt-hour. The system uses surplus electricity to blow air at 600 degrees Celsius across a packed bed of basalt rocks in an insulated container.

• The National Law Review takes a detailed look at the impact of the newly revised Toxic Substances Control Act on chemical importers, noting that "companies planning to ship chemical-based products to the United States should have a basic understanding of the TSCA." 

• Researchers from the Universidad Politécnica de Madrid have invented a new thermal energy storage system that uses molten silicon to store up to 10 times more energy than existing storage devices. "The proposed new thermal energy storage system," according to a report in New Atlas, "involves heating the silicon in a container using either concentrated sunlight on surplus electricity generated by renewable power. The molten silicon – which can reach temperatures of around 1,400° C (2,552° F) – can be isolated from its environment until energy is needed, at which point the heat is converted to electricity."  

SolarReserve has proposed building the world's largest solar power plant in Nevada. The 2-gigawatt Sandstone project would include up to 10 concentrated solar arrays, each equipped with a molten salt thermal storage system. 

SUNCNIM has raised 60 million euros to help finance construction of the world’s first commercial Fresnel concentrated solar power plant with energy storage. The plant in the French Pyrenees will have four hours of thermal storage capacity. The thermal energy will be converted into electricity by a steam generation process.

Ministry, whose high-tech clothing line includes dress shirts infused with phase change material, has opened a store in downtown Chicago

• The American Society of Interior Designers has opened a Material ConneXion library at the society's new corporate headquarters in Washington, D.C. The Materials ConneXion database lists more than 7,500 "unique, innovative and sustainable materials." PureTemp's biobased phase change materials were added to database last year.

Ember Technologies, which raised more than $350,000 on IndieGoGo last year to develop a temperature-adjustable mug, sent backers another update this week: "We are happy to announce that shipping will begin the first week of November for our pre-order customers." Delivery was initially set for April 2016. The $150 mug uses bio-based phase change material and a microprocessor-controlled heating system to maintain hot beverages at temperatures set by the user.

• New from Market Research Engine: "Global Microencapsulation Market Research Report - Industry Analysis, Size, Share, Growth, Trends and Forecast, 2014 - 2021." The report projects the market will reach $8.5 billion by 2021, a compound annual growth rate of 8 percent.
