PCM briefing: Sasol introduces Parafol 17; CIC Energigune seeks scientific director for energy storage group

Ben Welter - Tuesday, March 07, 2017

• In a LinkedIn post, the chemicals giant Sasol has announced the development of a new phase change material, Parafol 17. The product has a melting range of 20-22º Celsius. Potential applications include building/construction and the transportation of temperature-sensitive goods. The company says the new PCM is commercially available, but it is not yet listed on the company's websites.

CIC Energigune is seeking candidates for the position of scientific director in its energy storage group, which is focused on the research of systems that can store heat from medium to high temperatures.

Colorado's first certified passive house 'has gone well past expectations'

Ben Welter - Wednesday, January 04, 2017

Colorado's first certified International Passive House is nestled in the foothills of the Rocky Mountains north of Denver. The 1,200-square-foot MARTaK house, designed by architect and author Andrew Michler, is used primarily as an off-the-grid workspace. The structure has now been occupied continuously for six months. Has it met Michler's energy expectations?

MARTaK passive house photo by Andrew Michler"Yes," Michler says, "it's gone well past my expectations. ... We haven't turned on the heating system this year." 

A solar array shared with a neighboring home provides all electrical power and most of the heating, with a propane-powered hydronic system serving as backup. Passive House Planning Package software was used to find the most efficient mix of insulation, windows and shading. Natural, nontoxic and recycled materials are used throughout the house. 

Biobased phase change material with a melt point of 23º C is used to help even out temperature spikes. The PCM is contained in 500 square feet of ENRG Blankets made by Phase Change Energy Solutions. Most of the material is installed a south-facing interior wall. 

Is it possible to measure the PCM's impact on overall performance?

"That's the question that I haven't found anybody able to answer," Michler says. "It's more about experiential. It's hard to isolate the PCM performance. There's no good modeling software for this. ...

"Overheating has been the biggest issue with passive houses, and we're seeing some anecdotal success with PCMs. We had a really warm fall, and the PCM did seem to level out the interior temperature, leveling out at 78 degrees Fahrenheit."

Has Michler used PCM in other projects? "No, this is the first. I do have interest in trying it again."

2016 Presidential Green Chemistry Challenge Award winners named

Ben Welter - Thursday, June 23, 2016

Verdezyne of Carlsbad, Calif., which developed a greener way to make high-performance nylon, is among this year's Presidential Green Chemistry Challenge Award winners. Verdezyne's process uses a plant-based feedstock and does not employ high temperatures or concentrated nitric acid. The nylon is used in hairbrushes, toothbrushes, adhesives, coatings, fragrances and other products. It has qualified for the USDA Certified Biobased label.

The U.S. Environmental Protection Agency award recognizes innovative technologies "that turn climate risk and other environmental problems into business opportunities, spurring innovation and economic development." The awards were present last week at the annual Green Chemistry & Engineering Conference in Portland, Ore. This year's other winners:

• Professor Paul Chirik of Princeton University discovered a new class of catalysts to produce silicones without the use of platinum.

Newlight Technologies of Costa Mesa, Calif., developed a plastic made from methane-based greenhouse gas. 

• Texas-based CB&I and Albemarle Corp. of Baton Rouge, La., developed and commercialized a safer technology to produce alkylate, a clean gasoline component.

Dow AgroSciences of Indianapolis developed and commercialized Instinct, an additive that reduces the leaching of fertilizer nitrate into ground and surface waters. 

Dr. William R. Sutterlin, Entropy Solutions' chief science officer, was a member of a University of Missouri team that won the academic award in 2006 for developing an inexpensive method to convert waste glycerin, a byproduct of biodiesel fuel production, into propylene glycol.

• The Global Cold Chain Forum is accepting nominations for the 2016 Cold Chain Excellence Awards. The four categories are Best Temperature Controlled Logistics Project; Most Innovative New Cold Chain Technology of the Year; Most Sustainable Temperature-Controlled Project; and Most Effective Risk Assessment, Evaluation & Mitigation for Transportation. Nominations are due by July 29, 2016.

Nike is teaming up with MIT's Climate CoLab to speed the development of innovative materials and shrink the company's supply-chain footprint.

Ice Energy's new Ice Bear residential cooling system was among the technologies highlighted at a White House summit on renewable energy and storage last week. 

• Puma's new PCM-infused jerseys made the wrong kind of impression at the European Championships this week. Four jerseys worn by Swiss players in a match against France tore apart when tugged on by opponents. Puma later apologized, blaming the problem on a bad batch of material damaged during production. It does not appear that the problem involved the phase change material used in strategically placed tape inside the jersey.

Pluss Advanced Technologies' Celsure cold chain shipper won the innovation of the year award at the Cold Chain Strategy Summit in Mumbai last week.

PCM briefing; China tightens vaccine-handling rules; Pelican BioThermal has new partners in Chile, Brazil

Ben Welter - Monday, May 09, 2016

China has strengthened cold chain regulations in the wake of a scandal involving the illegal sale of expired and improperly handled vaccines. County health officials are now required to get vaccines directly from manufacturers before sending them to hospitals, instead of going through wholesalers. Hospitals, clinics and government authorities must also keep better records of purchases and inventory, with regular monitoring of vaccine temperatures.

Pelican BioThermal, the temperature-controlled packaging specialist, recently announced partnerships with BioThermal Solutions of Chile and NatBio of Brazil.

Ice Energy is a founding member of the recently launched Community Storage Initiative, an industry group that includes utility trade associations, environmental groups, manufacturers and more than a dozen utilities. The Glendale, Calif., company makes the Ice Bear thermal energy storage system. "Community storage" refers to utility-sponsored programs that aggregate distributed energy storage resources such as water heaters, electric vehicles and interconnected storage batteries to deliver electricity to consumers more efficiently.

The global market for green chemistry, estimated at $11 billion in 2015, will explode to about $100 billion by 2020,  the American Sustainable Business Council and the Green Chemistry and Commerce Council report.
