Tower Cold Chain AIBTower Cold Chain, Theale, England, has added PCM plates to its on-board catering containers, eliminating the need for dry ice. The passive Advanced Insulated Boxes are designed to store perishable food, beverages and ice on passenger planes and trains. The containers can sustain temperatures at 5°C and below 0°C for up to 24 hours. “Dry ice is considered a hazardous material when transported and therefore requires strict compliance and regulatory training,” said Suzanne Hagley, business development manager. “Tower’s passive, on-board catering containers eliminate the need for such complexities, enabling airlines and train operators to carry food without compromising safety standards or creating dedicated supply chain networks at each station.”

Sonnert, who graduates this year with a degree in mechanical engineering, will use her year-long grant at the Lucerne University of Applied Sciences and Arts in Switzerland. She will create new equipment to observe salt segregation to advance the understanding of salt hydrates as a phase change material for thermal energy storage. Before starting her Fulbright fellowship, she will conduct droplet sorting research at the Norwegian University of Science and Technology in Trondheim.

• Italian startup i-TES has completed a new 1.4 million euro funding round. The company, operating within the University of Turin’s 2i3T business incubator, is developing thermal storage batteries with phase change materials and thermochemical materials. The joint investment effort is led by EUREKA! Venture SGR.

University of Edinburgh spin-out Exergy3 has been awarded a grant by the Department for Energy Security and Net Zero for a trial at a whisky distillery. Exergy3 says its “decarbonisation machine” can replace up to 100% of the fossil fuels currently used in high-temperature industrial processes. The modular energy storage system takes excess renewable energy from the national grid and stores it at temperatures of up to 1200C. The £3.6 million grant will help pay for installation of the technology at the Annandale Distillery in Dumfries and Galloway.

Lang-Bissell and Bissel at palaceSunamp Ltd. founders Susan Lang-Bissell and Andrew Bissell visited Buckingham Palace in June to receive the King’s Award for Innovation from King Charles. In a LinkedIn post, Bissell wrote: “It was fun. Met a number of other amazing exporters and innovators. And HRH the King. Which was nice. On a serious note: the importance of the fight against #climatechange was clear and evident across all key conversations in the room.”

Sunamp Ltd. is partnering with Trianco, a U.K. heating and hot water equipment vendor, to introduce ActivAir Plus, a product that pairs Sunamp’s Thermino heat battery with Trianco’s ActivAir heat pump. “Thanks to the compact size of the heat battery and reduced number of components,” Sunamp says, “the ActivAir Plus package is easy to handle and arrives on one single pallet, significantly reducing packaging waste and simplifying logistics. It offers installers, landlords and homeowners a one-stop-shop and one delivery solution for transitioning to renewable heating systems.”

Registration is open for the 3rd edition of the Summer School on Latent Thermal Energy Storage. The program, to be held Sept. 4-8 at the University of Padova, Italy, will focus on the role of LTES on decarbonization. Jörg Worlitschek, Anastasia Stamatiou and Simone Mancin are coordinating the program, which is designed to provide young scientists in industry and academia an opportunity to learn from leading LTES experts. Professor Luiza Cabeza of the University of Lleida, Spain, will deliver a lecture on performance indicators for LTES. The registration fee is 790 euros for Ph.D. students, with higher fees for academic and industrial staff. The registration deadline is July 15.
