PCM briefing: Stanford energy hub wins AIA award; is that PCM atop a Japanese greenhouse?

Ben Welter - Friday, January 20, 2017

Stanford University's new Central Energy Facility, the heart of a campus-wide energy system, has won a 2017 Institute Honor Award, the American Institute of Architects' highest recognition for design excellence. A 2.5-million-gallon hot water tank in the courtyard showcases the energy plant’s mission.

Greenhouse in Yamaguchi Prefecture• A strawberry-cultivation system that stores excess solar heat in a tank filled with cobblestones reduced heating costs by 80 percent at a greenhouse in Japan's Yamaguchi Prefecture. "A mat-like heat-insulating material" – phase change material, perhaps? – atop the greenhouse, right, is rolled up during the day to let in sunlight.

A power plant under construction in Kiel, Germany, will be able to store more than 1,500 megawatt hours of heat in a 60-meter-high water tank, ensuring the supply of more than 70,000 district heating customers for up to eight hours. The gas-fired Stadtwerke Kiel will simultaneously generate electricity and heat through cogeneration.

PCM briefing: Siemens touts packed-bed thermal storage breakthrough; TSCA's impact on chemical importers

Ben Welter - Thursday, October 20, 2016

Siemens says its recently launched packed-bed thermal storage concept for wind power could deliver energy at well below 0.10 euros per kilowatt-hour. The system uses surplus electricity to blow air at 600 degrees Celsius across a packed bed of basalt rocks in an insulated container.

• The National Law Review takes a detailed look at the impact of the newly revised Toxic Substances Control Act on chemical importers, noting that "companies planning to ship chemical-based products to the United States should have a basic understanding of the TSCA." 

• Researchers from the Universidad Politécnica de Madrid have invented a new thermal energy storage system that uses molten silicon to store up to 10 times more energy than existing storage devices. "The proposed new thermal energy storage system," according to a report in New Atlas, "involves heating the silicon in a container using either concentrated sunlight on surplus electricity generated by renewable power. The molten silicon – which can reach temperatures of around 1,400° C (2,552° F) – can be isolated from its environment until energy is needed, at which point the heat is converted to electricity."  

SolarReserve has proposed building the world's largest solar power plant in Nevada. The 2-gigawatt Sandstone project would include up to 10 concentrated solar arrays, each equipped with a molten salt thermal storage system. 

SUNCNIM has raised 60 million euros to help finance construction of the world’s first commercial Fresnel concentrated solar power plant with energy storage. The plant in the French Pyrenees will have four hours of thermal storage capacity. The thermal energy will be converted into electricity by a steam generation process.

PCM briefing: Phase change material in concept motorcycle and automotive interiors

Ben Welter - Wednesday, August 10, 2016

Can-Am Spyder e-motorcycle• Bombardier Recreational Products of Canada has produced an electric version of its three-wheel Can-Am Spyder motorcycle. The concept vehicle is equipped with a 16 kWh battery and has a range of about 170 km (106 miles). Phase change material is used to cool the lithium-ion batteries. No word on whether a production model is planned.

Dr. Barbara Pause of Textile Testing & Innovation will be among the speakers at this year's Industrial Fabrics Association International Expo in Charlotte, N.C. The topic of her Oct. 18 presentation: "Taking the heat – thermal control of the automotive interior with phase change material."

CALMAC is applauding the Massachusetts Legislature for approving an "energy diversity" bill that promotes the use of renewable energy sources and energy storage technologies. The legislation, signed into law Monday by Gov. Charlie Baker, requires the state to seek long-term contracts for 1,600 megawatts of offshore wind power and 1,200 MW of hydropower. Its broad definition of energy storage includes distributed thermal energy storage such as CALMAC's IceBank system. "It is unrealistic to believe that renewable energy will align itself perfectly with the demand of the power grid and consumers without adding energy storage," said Mark McCracken, the company's CEO. "Massachusetts has taken great steps to create a more reliable, smarter grid to adapt to future needs.”

• Got a big tank to clean? You might want to contact CYC International of Singapore. The plant maintenance company has created a snake-like robot to clean tanks at oil refineries. CYC says use of the remote-controlled robot reduces the number of workers needed to clean a tank, lowering health and safety risks and improving productivity.

Ben Welter - Wednesday, April 13, 2016



NASA has partnered with the International Space Station to test the next generation of phase change material heat exchangers for use aboard the Orion spacecraft. The PCM HX helps maintain a comfortable environment by absorbing and ejecting excess heat. The test platform pumps a mix of propylene glycol and water through the PCM HX at temperatures between -10º and 30º Celsius. The wax PCM was developed by UTC Aerospace Systems.

ARPA-E is looking for input on the development of low-cost occupancy sensors to help minimize the energy used to heat and cool buildings.

• The world's renewable energy capacity grew by a record 152 gigawatts in 2015, or about 8.3 percent, according to the International Renewable Energy Agency. Solar capacity grew by 47 gigawatts, or 26 percent, as the cost of PV panels continued to fall.

• Appearing at last month's Solar Heating and Cooling Workshop in Melbourne, Frank Bruno, associate research professor at the University of South Australia, said phase change material thermal storage is cheaper than batteries for solar storage, costing around $200 (AUD) per kilowatt-hour of storage capacity, compared to $1,500/kWh for batteries.

Greentech Media notes that RAP gives one element — water — far more emphasis: "For the first time, managing water and wastewater pumping loads has been added as a strategy. Water heating and ice energy also have more prominent roles."

Thermal storage is in the mix for Texas utility seeking big increase in solar

Ben Welter - Tuesday, February 09, 2016

In an effort to reach a goal of deriving 55 percent of its energy from renewable sources by 2025, a Texas utility is adopting energy storage and software tools to accommodate a big increase in solar power. Utility Dive reports that Austin Energy is developing a plan for distribution-connected local storage of at least 10 MW complemented by as much as 20 MW of thermal storage. The test program is being implemented under a $4.3 million award from the Department of Energy’s SunShot Initiative.

Beyond shell and tube: POWER magazine's Aaron Larson takes a look at the latest innovations in heat exchanger technology. Expanded metal baffle designs, such as the one shown above from EMbaffle B.V., promise better heat transfer and eliminate flow-induced vibration.

Esquire magazine selected the Ember temperature-adjustable mug, powered in part by phase change material, as one of the top five gadgets among the thousands displayed at last month's Consumer Electronics Show in Las Vegas. 

German researchers are developing a PCM-based thermal energy storage using salt hydrates and hybrid double-shell concrete tanks. The goal is to convert excess electricity from renewable sources and store it as heat for use in a single building or shared in a smart grid of neighborhood buildings.

Plans for Dutch Windwheel include underground thermal energy storage

Ben Welter - Friday, January 22, 2016

Drawing of proposed Dutch Windwheel

A consortium behind plans to build the Dutch Windwheel, a 570-foot-tall 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."
