The Sub-Marine Tunnel Beneath The English Channel Releases Energy Efficient Data


The biggest tunnel in the world stretching under the sea delivers on its biggest sustainable efforts of maintaining optimal ambient temperature with the reduction of environmental footprints.

Dailycsr.com – 25 June 2018 – On June 8, 2018, the Eurotunnel published its “official data” which demonstrates saving of energy consumption by 33%. This change has been noted following the “first season” of a “new cooling system” has been made operational in an attempt to maintain the “requisite temperatures in the landmark Channel Tunnel”.
According to reports, the Eurotunnel’s operators saved around “4.8 GWh” in 2017 which can run nearly “1,000 households” and approximately costs “€500,000”. The data released, post the new cooling system has been made operational, is a dramatic boost to the “sustainability efforts” of Eurotunnel. Till date the Eurotunnel has earned five consecutive recognition from the “UK’s Carbon Trust Standard” with a certificate for a further 9% reduction of its “carbon footprint in 2015-2016 compared to 2012-2013”.
Getlink is the owner of “Channel Tunnel”, whereby its deputy chief executive officer, François Gauthey stated:
“Eurotunnel’s commitment to environmental protection involves a number of initiatives. We saw the replacement of the Channel Tunnel cooling system as a chance to reduce our energy consumption and carbon footprint. This effort required installing a new cooling system—Europe’s largest—to maintain the Channel Tunnel at optimal ambient temperatures. Honeywell’s Solstice® zd refrigerant, with its ultra-low global warming potential (GWP), and Trane’s chillers, which are already being used to cool large buildings and infrastructure, provided the best combination of features to help us meet our energy and environmental goals.”
The sub-marine tunnel joins “Folkestone, Kent, in the United Kingdom with Coquelles, Pas-de-Calais, in northern France”. There needs to be a cooling system all “round-the-clock”, or else the high speed trains movements passing through the channel will raise the inner tunnel temperature to over “35°C”, a maximum temperature to maintain optimal running condition. However, the new cooling system installed in the tunnel beneath the English Channel keeps the “ambient temperatures” around “25°C”.
While, Trane Europe’s General Manager as well as the Vice-President, Jose La Loggia added:
“The Series E is part of our EcoWise portfolio of products designed to lower environmental impact with next-generation, low global-warming-potential refrigerants and high-efficiency operation – consistent with our company-wide commitment to introduce products that reduce greenhouse gas emissions. These chillers have been successfully used in various applications across Europe and have helped our customers to achieve operational savings while lowering their environmental footprint, without compromising safety, reliability and performance.”
Furthermore, the General Manager as well as the Vice-President of “Honeywell Fluorine Products” for “Europe, Middle East and Africa”, Julien Soulet said:
“Worldwide demand is growing for solutions like Solstice zd, which offer the best combination of features to help companies achieve their environmental goals. The use of our refrigerants to cool major structures like the Channel Tunnel in Europe demonstrates their easy adaptability to even the largest or most challenging cooling situations, all while providing energy savings, carbon reduction and regulatory compliance. We are committed to helping industries transition to and adopt next-generation, lower-GWP solutions.”
