Sunamp, Trina Solar sign deal to combine thermal batteries with heat pumps

Ben Welter - Monday, November 05, 2018

Sunamp Ltd. has signed an agreement with Trina Solar to develop an integrated solution combining Sunamp heat batteries now made in Scotland with heat pumps manufactured at Trina's new factory in Changzhou, China.

With more than 14,000 employees, Trina is one of the world's largest PV panel manufacturers. Sunamp, based in Edinburgh, Scotland, has about 30 employees. Sunamp's Uniq heat batteries, made at Sunamp's factory in East Lothian, use a salt-based phase change material to store excess energy generated by solar PV systems. The stored energy is released on demand to provide heat and hot water.

The two companies signed a memo of understanding Oct. 20 at the opening of Trina’s new heat pump factory.

Trina Solar VP John Ding, left, with Sunamp CEO Andrew BissellThe combined system will use Sunamp’s batteries in conjunction with solar panels and heat pumps to reduce energy costs and carbon emissions. According to Sunamp, the system will offer 23 to 35kWh of storage.

“Our unique heat battery technology extends and enhances the range of capabilities of heat pumps, and the combination of solar PV, heat pumps and heat batteries has exceptional potential to cut fuel costs, address climate change and improve air quality," said Sunamp CEO Andrew Bissell (right, with Trina Solar VP John Ding).

Sunamp’s heat batteries, which have been installed in thousands of homes across the UK, will be paired with Trina heat pumps as part of a trial of the integrated solution in 20 homes in northern China this winter. If the trial is successful, the integrated solution will be launched in China in the second half of 2019.

The collaboration with Trina is Sunamp's largest to date, in terms of manufacturing scale and potential revenue. He and Maurizio Zaglio‎, Sunamp's international business development manager, provided details on the agreement in phone and email interviews last week.

Q: How did Sunamp make the initial contact with Trina?

A: "Mr Eagle Su and Professor Feng visited our factory earlier in the year. Eagle is the general manager of Trina Energy Management Co. Ltd, which is the section charged with launching Trina into the heat pump market. Professor Feng heads up the Trina Institute of Strategic Studies in Beijing."

Q: The article mentions Trina's "expansion into the heat pump market." Is the new factory in Changzhou producing Trina's first heat pumps?

A: "Yes. We signed our memo of understanding at the launch event. We were one of only two non-Chinese Companies invited to the launch (the other was Danfoss). The launch was 'full on' with over 1,000 installers visiting the Trina Energy heat pump factory on the Friday and a large indoor event on the Saturday with over 350 attendees, including key management from all leading heat pump vendors in China, local and national government and institutions fully represented, and led in 'keynote style' by the CEO of Trina Solar, Jifan Gao."

Q: What stood out for you on your visit to the factory?

A: "It had very modern, state-of-the-art manufacturing equipment and we were struck by the very full lineup of products ranging from small room-scale to 150kW large commercial/industrial heat pumps. Trina are clearly VERY serious in entering the heat pump market."

Sunamp's UniQ heat batteriesQ: What are the key features of the latest version of the Uniq heat battery?

A: "They are even more compact and installable than our previous Gen 2 (SunampPV) products ... Very flexible on inputs (solar PV, thermal, grid electricity, heat pumps ... Two outputs at once (e.g. heating and hot water) ... No need for the usual extra plumbing needed with a hot water cylinder ... Highest thermal efficiency and A+ rated under Europe’s ErP (Energy-related Products) directive at all sizes UniQ 3, 6, 9 and 12 NB. No range of hot water cylinders is A+ rated across the range. Most can muster a B or A at the smallest size (like 70L, equivalent of the UniQ 3) but this drops off to B, C or D at larger sizes. Sunamp is A+ all the way ... They are ready for deep integration to heat pumps via refrigerant loop ... We warranty the storage for 10 years ... Extremely cost effective on all of lifetime, OpEx and CapEx measures ... They look good (much less clutter than water tanks)."

Q: Talk about the PCM used in the battery.

A: "It's our flagship material, SU58, with a melt point of 58 Celsius, sodium acetate trihydrate, with a couple of components that are there to ensure nucleation and ensure stability. And they do that. [In testing] we've reached 40,000 cycles now, which is, we think, pretty convincing at full heat battery scale. These are done on a 2.5 kWh heat battery, full cycle being 40 degrees to 80 degrees back to 40. It still has significantly more than 95 percent capacity at that point. To be honest, we stopped testing. That's a lifetime's use for any reasonable product ... about 50 years."

Q: Assuming the trial goes well, will you shift some production to China?

A: "More than likely. It doesn't make sense to ship things over a huge distance that can be made efficiently and effectively right next to where they can be integrated with the heat pump for the local market. Trina has a very large campus, with three PV factories and the heat pump factory. If they want us to be on that campus, there's more than enough space."

Q: The combined system is said offer between 23 and 35kWh of storage. Are those numbers based on tests of full-scale prototypes?

A: "We have fully trialled this kind of heat pump plus heat battery (plus solar PV) in a number of UK test homes. These sizes come from that trial base. A full trial is planned in China over this winter involving Sunamp and led by Trina."

Q: What excites you most about this opportunity?

A: "The scale of ambition shown by both the Chinese government and Trina in responding to it. 66 million homes in China still source their heat and hot water from coal. This has major impacts on both air quality and carbon emissions leading to climate change. We are really excited to be partnered with Trina in their strategy to address this. And also to be partnered on the wider level with such a leading company."

PCM briefing: Isomer can store energy for up to 18 years; concept combines pumped storage and heat storage using water as a medium

Ben Welter - Friday, November 02, 2018

• Researchers at Chalmers University of Technology and Universidad de La Rioja have created a system capable of storing solar energy for extended periods. The Molecular Solar Thermal Energy Storage system uses a molecular photo switch made from carbon, hydrogen and nitrogen. Sunlight turns the molecule into an energy-rich isomer. The isomer can be stored in a liquid form to be used for heating at night or in winter. “The energy in this isomer can now be stored for up to 18 years. And when we come to extract the energy and use it, we get a warmth increase which is greater than we dared hope for,” said Kasper Moth-Poulsen, professor at Chalmers.

Ice Cub is now available to California homeowners, builders

Ben Welter - Friday, October 12, 2018

The Ice Cub, Ice Energy's hybrid air-conditioning and thermal energy storage system, is now available for purchase by California homeowners and homebuilders.

The solar PV-compatible unit replaces a conventional 5-ton outdoor condensing unit and is designed to work seamlessly with home HVAC systems. The Ice Cub functions like a typical condensing unit, but it also makes ice to store up to four hours' worth of cooling.

"For homes with solar PV," Ice Energy says, "a full tank of ice can be made and stored during the day, using what would otherwise be surplus solar generation."

The Ice Cub retails for $15,000. But Ice Energy says two government incentives potentially reduce the cost of purchase and installation to below that of a conventional air conditioning system. The Ice Cub qualifies for California’s Self-Generation Incentive Program rebate and, for homes with solar PV, the federal Solar Investment Tax Credit. Ice Energy says the payback period for an Ice Cub installed in a California home with solar PV is less than one year.

The company, based in Southern California, says it is in the early stages of recruiting regional project partners such as homebuilders and HVAC installers.

“Conventional AC units in California have become increasingly expensive to operate as the state’s new time-of-use rates take effect,” said Joseph Draper, executive chairman of Ice Energy. “The Ice Cub, by contrast, reduces consumption of expensive electricity and can save homeowners as much as $1,500 a year on their utility bill. The smart, energy-efficient Ice Cub is a true consumer product with real potential to render conventional home AC units obsolete. We are very excited to make it available for immediate delivery to homeowners and builders here in California.”

10 BioPCM products added to USDA BioPreferred catalog

Ben Welter - Wednesday, September 26, 2018

Phase Change Energy Solutions has joined PureTemp and Croda International in the U.S. Department of Agriculture's BioPreferred catalog. The North Carolina manufacturer has registered 10 of its phase change materials in the program: BioPCM Q4, Q6, Q8, Q15, Q18, Q20, Q23, Q25, Q27 and Q29.

The USDA defines biobased products as finished or intermediate materials composed in whole or in significant part of agricultural, forestry or marine ingredients. The program’s purpose is to increase the purchase and use of biobased products. Products that meet the USDA BioPreferred program requirements carry a distinctive label for easier identification by the consumer.

Reyad Sawafta“BioPCM is now certified with 100% biobased content and listed among the USDA BioPreferred products, demonstrating our commitment to sustainability as we work to meaningfully reduce energy consumption," said Dr. Reyad Sawafta, chief scientific officer at Phase Change Energy Solutions.

Seven CrodaTherm products qualified for the program in 2016. PureTemp first qualified in 2014, and 23 PureTemp formulations are now designated as 100 percent biobased by the program.

Phase change material is not currently one of the 109 categories in the USDA's BioPreferred Program. Phase Change Energy Solutions, Croda and PureTemp became certified through a voluntary labeling initiative. The USDA published a proposal last week to add PCMs as a category of biobased products eligible for procurement preference by federal agencies and their contractors.

The BioPreferred Program was created by the Farm Security and Rural Investment Act of 2002 and expanded by the Food, Conservation, and Energy Act of 2008. Under the program, federal agencies are required, with some exceptions, to purchase biobased products within designated product categories when the purchase price of the product exceeds $10,000 or when the quantity of such products or functionally equivalent products purchased over the preceding fiscal year equaled $10,000 or more.
