PCM briefing: A call for presentations on renewable heating and cooling; EnergyNest, Tata team up on demo project

Ben Welter - Friday, April 07, 2017

Frank Bruno, leader of the Thermal Energy Storage Group at the University of South Australia, talks about the advantages of thermal storage in an interview with the Guardian newspaper.

Robert Riebolge, chief network analyst of the Adelaide-based energy storage company 1414 Degrees, tells Ecogeneration magazine that storage is “quite clearly” the solution to the intermittency problem of wind and solar. But, he says, the way in which the Australian market is constructed and the regulatory system is set up doesn’t allow for its easy introduction.

PCM briefing: India startup wins Energy Transition award; new market research on thermal energy storage

Ben Welter - Monday, March 27, 2017

Thermal Energy Service Solutions, maker of a PCM-based "plug-and-chill" refrigeration system, was one of six startup companies honored at Tech Festival 2017 in Berlin last week. The Indian company's cooling technology is designed to reduce the use of fossil fuels in storing and transporting food. The Startup Energy Transition Awards competition, sponsored by the German Energy Agency, drew more than 500 applications from 66 countries.

Machine learning tools can help researchers analyze sustainable products and chemicals more easily, but as with all computing, data quality is important, writes Christina Valimaki, senior director of chemicals at Elsevier's R&D Solutions.

PCM briefing: Pluss VP honored as 'Innovator under 35'; BASF partners with Hewlett Packard Enterprise on new supercomputer

Ben Welter - Tuesday, March 21, 2017

Ankit Jhanwar, VP for corporate planning and strategy at Pluss Advanced Technologies, was honored as one of 10 "Innovators under 35" at EmTech India 2017.

Sunamp Ltd., maker of PCM-based heat batteries, is one of eight finalists for an Ashden UK Award. Winners will be announced at a ceremony in London on June 15. The competition recognizes excellence in the field of green energy.

Hewlett Packard Enterprise will work with BASF to develop a supercomputer that will sharply reduce the time it takes to run simulations and modeling in chemical research. "The new supercomputer will promote the application and development of complex modeling and simulation approaches, opening up completely new avenues for our research at BASF,” said Dr. Martin Brudermueller, chief technology officer at BASF.

McKinsey & Co. analysts say a slowdown in the chemical industry's financial performance over the past five years reflects important changes in the industry’s fundamentals. One of their recommendations: "Incumbent specialty-chemical players must prepare for further encroachment of commoditization and erosion of their historical advantages when attackers from developing markets gain more experience and become increasingly technologically savvy."

California lawmakers have introduced legislation to encourage more clean energy resources to address peak load. The bills would require utilities to deploy clean energy during peak demand in order to meet the state's aggressive greenhouse gas and renewable energy goals.
