Work continues on effort to add PCM products to California energy code

Ben Welter - Friday, March 16, 2018

At its meeting earlier this month, the RAL Quality Association PCM discussed an update on an initiative to include phase change material in the Building Efficiency Standards contained in the California Code of Regulations.

The update, provided by Jeremiah Crossett, chief technology officer of NRGsim Inc., outlined the initiative’s timeline and cost projections.

Crossett is developing a database of PCM products and performing a detailed modeling study on a variety of PCM products in all California climate zones. The goal is to build a persuasive case for including PCMs in the next version of the standards, to be published in 2019.

Manufacturers of PCM building products are invited to submit products to Crossett for inclusion in the database. One or two products can be submitted for $2,000; an unlimited number can be submitted for $5,000. For Crossett’s modeling study, $2,000 covers one or two products; $5,000 covers an unlimited number.

Crossett hopes to complete work on the initiative by next winter. He said Insolcorp, which installs PCM building products in California, Nevada and other states, has been covering the costs. He asked if any members of the RAL Quality Association PCM would be interested in co-funding the initiative. Members suggested that the new PCM Industry Association of North America would be a better audience for that question. Companies interested in participating can contact Crossett at jcrossett@nrgsim.com.

Value of TES 'not always fully recognized by policymakers'

Ben Welter - Wednesday, September 13, 2017

Heating and cooling in buildings and industry accounts for half of Europe's energy consumption, and yet the potential “immense value” of thermal energy storage has barely been explored, the head of an energy storage trade group says. 

Patrick Clerens“Despite its immense value to the energy system, the role of thermal energy storage concepts is not always fully recognized by policymakers,” Patrick Clerens, secretary-general of the European Association for Storage of Energy, said in an interview with Energy Storage News. 

“For example, the ongoing discussions about the energy storage definition in the European Parliament would appear to exclude thermal energy storage and Power-to-Gas, or Power-to-Liquids. A broader energy storage definition, such as the European Commission’s initial proposal, is needed to allow all energy storage technologies to be considered.”

In a position paper published in July, the trade group called for economic incentives such as accelerated depreciation, better regulatory framework to “ensure non-discriminatory access to energy grids” and improved support from European Union research agencies.

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."

• For the first time, scientists have recorded water freezing into a structure called Ice VII under extreme, controlled conditions in the lab, Science Alert reports. "These experiments with water are the first of their kind, allowing us to witness a fundamental disorder-to-order transition in one of the most abundant molecules in the Universe," says geophysicist Arianna Gleason of the Los Alamos National Laboratory in New Mexico.

• The Hohenstein Institute for Textile Innovation has developed a new method for measuring the cooling effect of intelligent textiles, a heat release tester called WATson. The institute's thermophysiological evaluation system "will compare the results of the WATson heat loss tester to data from experiments on subjects in a climate chamber under a range of ambient conditions," Advanced Textiles Source reports.   

• A team at the National Institute of Standards and Technology has submitted a precise new calculation of a key formula to redefine the kilogram based on a fundamental universal constant. 

• California startup Axiom Exergy, maker of behind-the-meter thermal energy storage systems, has an opening for a computational thermal systems engineer.
