Swiss symposium on thermal energy storage draws 135 participants

Ben Welter - Tuesday, January 31, 2017

TES economics, microencapsulation and new materials were among the topics at this year's Swiss Symposium Thermal Energy Storage in Lucerne.

The symposium, held Jan. 20 at the Lucerne University of Applied Sciences and Arts, drew 135 participants. Prof. Dr. Jörg Worlitschek, who organized the gathering, described the feedback from participants as “really positive.”

The 5th Swiss Symposium Thermal Energy Storage will be held on Jan. 26, 2018. Here’s a brief look at a few of this year’s presentations:

Dr. Luisa CabezaThermal Energy Storage: Possibilities and Outlook: Luisa F. Cabeza, right, University of Lleida, Spain, provided an overview of the basic principals and benefits of TES and offered an up-to-date look at strategic research priorities for sensible TES, latent TES and thermochemical storage.

Development of Latent Heat Transportation Systems with Various PCM: Hiroshi Suzuki, Ruri Hidema and Yoshiyuki Komoda, Kobe University, Japan, examined the process of microencapsulating PCM in a silica hard shell. Their conclusion: The material shows great promise for a variety of applications.

Thermoplastic Heat Storage Materials for Diverse Applications: Stefan Reinemann, head of plastics research at TITK, Germany, described the development of a PCM compound in which liquid paraffin is bound in a polymeric network structure. These PCM polymer storage granules have a “large heat transfer area,” melting ranges from -4 to 82 degrees C and a heat capacity of up to 180 joules per gram. The granules can be used in textiles, household appliances, building materials and prosthetics.

A Simple Tool for the Economic Evaluation of Thermal Energy Storage: Christoph Rathgeber, ZAE Bayern, Center for Applied Energy Research, Germany, presented two formula-driven ways to make a rough estimate of the economic viability of an energy storage for a specific application: Top-down (following the assumption that the costs of energy supplied by the storage should not exceed the costs of energy from the market) and Bottom-up (focusing on the realized storage capacity costs of existing storages). Among “long-term storages for building applications,” the analysis found that seasonal thermal storage is only economical via large hot water systems. Among “short-term storage for industrial applications,” the analysis found that ice storage systems are cost effective, and other technologies (such as mobile storage using sodium acetate trihydrate) are getting close.

PCM briefing: Long-haul cyclists reach Myanmar; papers sought for symposium on waste heat

Ben Welter - Friday, January 27, 2017

Riccardo Rocchi and Chiara RicciardiRiccardo Rocchi and Chiara Ricciardi,  the Italian couple who began an 18,000-kilometer bike ride in June to raise awareness about diabetes, have reached Myanmar. Ricciardi has type 1 diabetes and needs a daily dose of insulin. She is using Pelican BioThermal's Credo ProMed pack to keep insulin at the right temperature. The pair topped the 10,000-kilometer mark this week. They've pedaled across 16 countries, averaging 44 km per day. "We just realized that maybe we forgot to make a postcard from Nepal," the pair said in a Facebook post from Myanmar. "We might consider to cycle back to do it." Their final destination is Singapore.

• Organizers of a one-day symposium at Brunei University on the efficient use of waste heat have issued a call for abstracts. The symposium, "Heat Recovery and Efficient Conversion and Utilisation of Waste Heat," will be held April 20, 2017. Abstracts must be submitted by Jan. 31.

Pelican BioThermal has completed a $1.65 million expansion of the manufacturing facilities at its U.S. headquarters in Plymouth, Minn. The company now has 70,000 square feet of manufacturing space in the Minneapolis suburb, up from 54,000 square feet.

• The EU-funded Heat4Cool research project is developing a novel retrofit planning tool to help retrofit companies, architects, manufacturers, building administrators and residents weigh the potential benefits of three main technologies: gas and solar thermally driven adsorption heat pumps; PV-assisted DC-powered heat pumps connected to advanced modular PCM heat and cold storage systems; and energy recovery from sewage water with high performance heat exchangers. You are invited to help in this effort by completing a five-minute survey online.

• A Florida startup is calling its PCM-infused TempPro fabric “a gamechanger for luxury lingerie.” Giapenta, which launched a Kickstarter campaign this week, uses the temperature-regulating fabric in its line of bras, panties and sleep masks. The campaign has already met its modest target of raising $25,000. I've contacted the company and hope to have technical details on TempPro in time for next week's newsletter..

PCM briefing: Axiom Exergy's fast pitch; Peli BioThermal's new bulk freight shipper

Ben Welter - Wednesday, January 11, 2017

• Six energy storage startups made speed pitches at last month's Energy Storage Summit in San Francisco. Greentech Media takes a look at three of the pitches, including one made by Axiom Exergy co-founder Amrit Robbins. Axiom's PCM-powered "refrigeration battery" is designed to cut energy costs at supermarkets. "They are scrambling to reduce costs by just a few basis points -- and energy is a huge opportunity," Robbins said. "Saving $30,000 on a utility bill is the same as selling an additional $1.5 million of groceries."   

Peli BioThermal has introduced its new CoolPall Vertos Advance, a single-use, passive bulk freight shipper that incorporates phase change materials and vacuum insulation panels. 

• Scientists in the United Kingdom are developing a way to turn pinene, a paper industry waste product, into plastic. "We're not talking about recycling old Christmas trees into plastics, but rather using a waste product from industry that would otherwise be thrown away, and turning it into something useful," Helena Quilter, a Ph.D. student at the University of Bath's Center for Sustainable Chemical Technologies.

• Researchers at MIT have created three-dimensional samples of graphene that are up to 10 times stronger than steel, with just 5 percent of the density.

Sonoco ThermoSafe will offer its daylong master class on temperature assurance packaging on Feb. 2 at the Temperature Controlled Logistics conference in London. Sonoco, Peli BioThermal, CrodaTherm, Pluss Advanced Technologies, Ecocool and Cryopack will be among the exhibitors at the conference.
