A consortium behind plans to build the Dutch Windwheel, a 570-foot-high apartment and hotel complex in Rotterdam, has agreed to begin development and testing of a self-supporting energy system and other innovative technologies.
Underground thermal energy storage is among the components being studied for the "next-generation" windmill.
"Phase change materials, aquifer thermal energy storage and surface water thermal energy are a few of multiple options for managing the smart HVAC system in a sustainable way," said Gerard Blom, freshwater systems manager at the research institute Deltares, a member of the consortium. "Possibilities will be researched for local energy production (including the electrostatic wind energy convertor technology, solar and residual heat, and heat exchange), the water system, the development of a smart grid, the use of materials as well as technologies to enhance the experience and attraction value of the Dutch Windwheel and its environment."
London-based startup Open Energi is working with partner Tarmac to harness the thermal energy of hot asphalt. Open Energi plans to install its demand response system at 70 Tarmac plants in the United Kingdom, using 200-some asphalt tanks as fast-acting batteries for the electric grid. Thanks to "thermal inertia," the tanks stay close to the optimum 150° Celsius for long periods without electricity. Greentech Media's Jeff St. John explains:
"Each [tank] can be turned on and off, based on Open Energi’s moment-by-moment analysis of what grid operator National Grid needs to keep its system at a stable frequency of 50 hertz.
"This service, known as frequency regulation in the United States, is technically challenging, requiring large-scale resources to ramp up and down within seconds. This is a much more challenging set of tasks, compared to those required from traditional demand response programs in the U.S., or the U.K.’s Short-Term Operating Reserve (STOR) program, or its new capacity markets."
PureTemp phase change material, selected in October for display at Material ConneXion's flagship library in New York City, has now been chosen as one of the top 15 materials added to the library and online database in the past three months.
As part of the quarterly program, samples of PureTemp will be included in the library's Active Matter innovation box, which will be distributed to 100 corporate decision-makers around the world in the interior design, architecture, industrial design, product design, fashion, retail and electronics industries.
Material ConneXion is the world’s largest membership-based library, with more than 7,500 "unique, innovative and sustainable materials" and seven locations worldwide. Each month, an independent jury selects 42 new materials and processes for inclusion in the library.

U.S. patent application 20160016246 (applicant Orbital ATK Inc., Dulles, Va.):
"A two-phase heat transfer system includes an evaporator unit configured to receive heat from a source, a liquid line fluidly connected to the evaporator unit, a vapor line fluidly connected to the evaporator unit, and a condenser. The condensing unit includes a thermal capacitance device and a condenser integrated with the thermal capacitance device. Methods of forming a thermal storage unit include preparing a honeycomb core to receive a phase change material, metallurgically bonding end pieces to the core, to thermally link the end pieces to the core, and bonding the end pieces together to form a seal for holding the phase change material within the core."

More than 550 of your peers are members of a LinkedIn group devoted to the discussion of phase change material and thermal energy storage. The Phase Change Matters group is an interactive complement to the award-winning blog and newsletter of the same name.
You are invited to join the group and connect with PCM and TES experts from around the world. New members this week include Jean-Luc Battaglia, professor of thermal materials at the University of Bordeaux, France; Michael Corridan, co-founder of SolarThermiX Inc., Phoenix, Arizona; and Richard Sohn, vice president at Korea Energy Works Inc. Another new member writes:
"Hi, I am Cecilia Wolluschek, Physics PhD with thermal engineering and fluid mechanics specialization (heat transfer through two immiscibles fluids). Some years ago, I collaborated in different scientific project related with the PCM. Nowadays, I am Thermodynamics Professor in the Public University of Navarre, Spain and CEO at CW Consulting, a scientific and technical team of industrial consultants. I really interested in explore industrial applications of the PCM and in knowing the results of the recent research about them."
