Accelerate #111 is a Special Issue with a focus on how food retailers around the world are leveraging future-proof natural refrigerant solutions. In 26 case studies encompassing 46 stores, the issue gives best-practice examples of transcritical CO₂, hydrocarbon and ammonia/CO₂ installations. Some of the retailers profiled have taken transcritical CO₂ to the next level of sustainability by incorporating them in integrated systems that also include heating and air conditioning. Other stores have made transcritical CO₂ part of a strategy to reach net-zero carbon emissions. And one store shows how a transcritical CO₂ system can be leased instead of bought.

Accelerate #110 is a Special Issue with a focus on Clean Cooling, a new approach to HVAC&R. As defined by Professor Toby Peters of the University of Birmingham, U.K., Clean Cooling is “resilient cooling for all who need it, without environmental damage and climate impact and with the optimal use of natural and thermal resources throughout the lifespan of the cooling system.”

Also in Accelerate #110 are regional articles on: a Canadian ice rink that is leveraging heat reclaim from its CO₂ refrigeration system; a net-zero Lidl store in the Netherlands powered only by solar power and a thermal underground reservoir; an Australian entertainment center using propane-based air conditioning; and a Japanese fish processor that rebuilt a natural refrigerant-based facility following a devastating earthquake. Other articles include: cooling as a service in South Africa, and a new way to cool vaccines off the grid.

The April-May 2020 issue of Accelerate Magazine covers the latest research from Project Drawdown, which says that refrigerant management and alternative refrigerants are projected to reduce more than 100Gt of CO₂e emissions by 2050 – almost twice what all nations generated in 2018.

Also in the April-May 2020 issue are regional articles on: a North America study of ammonia accidents; a pioneering ammonia heat pump that taps heat from the London underground; a produce warehouse in Australia using a low-charge ammonia package; and a Tokyo department store that installed a CO₂ water-loop system.

The manufacturers point to the growth of CO₂ and propane systems in a range of store formats, improving energy efficiency, and greater adoption of integrated systems.

Also in the February 2020 issue, regional articles on: a custom transcritical CO₂ system in hot, muggy Florida, U.S.; Polish retailer Biedronka, the king of the retrofits; a Kenyan fish processing facility upgrading to ammonia; a Woolworths store in Australia meeting the “Living Building Challenge”; and Japanese retailer Lawson opening its first NatRef store in China. Global trend articles include: CO₂ refrigeration in space, 3D printing for HVAC&R, IoT for supermarkets, and a Thought Leader Q&A with Indonesian consultant Herlin Herlianika.

This 2020 Special Corporate edition of Accelerate Magazine is all about future-proofing refrigeration installations around the world by using natural refrigerants such as CO₂.

Accelerate Corporate captures the efforts of market leaders in advancing the use of natural refrigerants across different applications, industry sectors and continents. Each issue of the magazine is prepared in partnership with an influential corporation, organization or group of entities striving to accelerate the uptake of climate-friendly, natural refrigerant-based technologies.

Accelerate Corporate seeks to showcase end users’ experiences working with natural refrigerants and to highlight the underlying market, policy and technology trends driving their uptake. From the U.S. to Australia, we look at CO₂ end user stories around the world.

This edition was made possible with the support of South African CO₂ pioneers – Sphere.

The January 2020 issue of Accelerate Magazine celebrates the women working around the world in the natural refrigerants industry. These 29 profiles reveal the extraordinary impact women are having in a male-dominated industry.
