The LNG-fuelled fleet continues to grow
According to the maritime classification and consultancy company DNV, orders for LNG-fuelled ships remained high in 2022, close to the record figure of 2021. The use of LNG as a...
Ultra-low temperature systems ready for COVID-19 vaccine storage
Mirai Intex, corporate member of the IIR, is positioning its ultra-low-temperature (ULT) systems to serve as the refrigeration technology for the storage of COVID-19 vaccines and the freeze-drying of the...
Reducing the environmental impact of ultra-low temperature refrigeration systems
Ultra-low temperature (ULT) refrigeration systems often use very high-GWP HFCs. Yet, ULT systems are excluded from the scope of the regulations aimed at phasing-down HFCs. An IJR paper reviews the most promising...
Australia to set up a carbon price for HFCs
In September 2011, the Australian Government introduced to the Parliament a set of Bills that aim to cut emissions of greenhouse gases by 159 million tonnes CO2 eq. a year. Included are bills that will introduce a carbon charge on imports of...
