The compound annual growth rate for the biobased phase change material market in the Americas is projected to be 28.9 percent between 2013 and 2018, according to MicroMarket Monitor's latest report on the topic. That's an increase of nearly 2 percentage points over rate projected in MicroMarket's October report.
A team led by Syracuse University has been awarded a $3.2 million grant by the Advanced Research Projects Agency-Energy to develop a "micro environmental control system" for office buildings. The team, which also includes Air Innovations, Cornell University, United Technologies Research Center and Bush Technical LLC, is working on a micro vapor compression system that has an evaporator embedded in phase change material.
The cooling produced by the micro vapor will be stored in the PCM at night and released during the day. The unit, about the size of a desktop computer, will maintain comfortable micro climates and allow thermostats for bigger spaces to be set 4º F higher or lower than is now typical. The team's goal is to achieve at least a 15 percent reduction in heating and cooling costs.
"It is a complex approach," he explained. "One the one hand, we have to calculate how much primary energy can we save; on the other, how much it costs. Technologies have to be easy to install and maintain and [incur] a limited investment cost. If they are expensive, we have to understand whether it makes sense to install them. And this analysis has to take into account the energy concept of a specific building replaced in its own environmental context."
Frigesco Ltd. has been invited to present an update on its flash frost technology at CleanEquity Monaco 2015 in March. The annual conference, hosted by the investment bank Innovator Capital, brings together industry experts, government officials, policymakers and investors to discuss "next generation" clean technology.
The British company's technology harnesses waste heat to defrost refrigeration systems more efficiently, reducing supermarket cooling costs by up to 20 percent. Phase change material is used to store the waste heat.
NBC News' John Roach reports that falling costs and industry-friendly policy incentives for thermal energy storage could help make wind- and solar-generated electricity a multibillion-dollar industry in the next decade.
