Located in Marseille<a href=\"https:\/\/www.engie.com\/en\/journalistes\/communiques-de-presse\/thassalia\">, Thassalia \/ Engie Cofely<\/a>, work began on the new installation in September 2014, and the plan was that it would&nbsp;be used to run the air-conditioning inside the buildings (housing, hotels, and offices), making up the planned Euromed Centre, located behind the Silo d&rsquo;Arenc.&nbsp;The marine geothermal technology uses the difference in temperature between hot surface water and cold water from the seabed. Pipelines pump the water, and heat exchangers and heat pumps create hot or cold water as needed. The water is then sent to buildings for heating or cooling purposes. Until 2020, the power plant had supplied 500,000 m&sup2; of offices and, in 2021, was also applied to the 63,000 m&sup2; of Les Terrasses du Port shopping centre. Implementing the power station also helped create 60 direct and indirect jobs, reduced noise and the need for cooling towers on buildings, and helped save 70% of CO2 emissions,&nbsp;minimise energy use by 40%, and water consumption by 65%.<\/p>\n<p dir=\"ltr\">Another renewable energy network was implemented in Marseille in 2017.&nbsp;&ldquo;<a href=\"https:\/\/www.massileo.fr\/node\/136\">Massileo<\/a>&rdquo; is part of&nbsp;the&nbsp;Smartseille project in the new EcoCit&eacute; Eurom&eacute;diterran&eacute;e district.&nbsp;It is a thalassothermic network that&nbsp;uses marine energy.&nbsp;The <a href=\"https:\/\/www.eiffageconstruction.com\/realisations\/marseille-ecoquartier-smartseille\">Smartseille project<\/a> is part of the Eurom&eacute;diterran&eacute;e development and reconversion effort, focused on creating a sustainable city in line with the regional and geographical specificities. The Massileo network connects the calorie recovery plant in the port to the heat pumps installed in the basement of buildings via a tempered water loop. The idea is to extend the supply to all the&nbsp;heating or air conditioning&nbsp;of&nbsp;the offices, shops and dwellings present on the 2,7 hectares of this eco-district.&nbsp;The system also allows buildings to exchange waste energy from heat pumps as both consumers and producers of energy. The network helped reduce 80% of the CO2 emissions and uses 75% of renewable energy.<\/p>\n<p dir=\"ltr\"><span style=\"text-decoration: underline;\">Additional information<\/span><\/p>\n<p>&nbsp;<\/p>\n<p dir=\"ltr\" role=\"presentation\"><a href=\"https:\/\/www.engie.com\/en\/journalistes\/communiques-de-presse\/thassalia\">https:\/\/www.engie.com\/en\/journalistes\/communiques-de-presse\/thassalia<\/a>&nbsp;<\/p>\n<p dir=\"ltr\" role=\"presentation\"><a href=\"https:\/\/www.construction21.org\/infrastructure\/fr\/thassalia-france-s-first-marine-geothermal-power-plant.html\">https:\/\/www.construction21.org\/infrastructure\/fr\/thassalia-france-s-first-marine-geothermal-power-plant.html<\/a><\/p>\n<p dir=\"ltr\" role=\"presentation\"><a href=\"https:\/\/www.massileo.fr\/node\/136\">https:\/\/www.massileo.fr\/node\/136<\/a><\/p>\n<p dir=\"ltr\" role=\"presentation\"><a href=\"https:\/\/www.construction21.org\/infrastructure\/fr\/massileo-the-smart-renewable-energy-network.html\">https:\/\/www.construction21.org\/infrastructure\/fr\/massileo-the-smart-renewable-energy-network.html<\/a>&nbsp;<\/p>\n<p dir=\"ltr\" role=\"presentation\"><a href=\"https:\/\/www.eiffageconstruction.com\/realisations\/marseille-ecoquartier-smartseille\">Smartseille : reconversion d&#8217;une friche industrielle en d&eacute;monstrateur industriel pour la ville durable<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In 2016, France inaugurated its first marine geothermal power station.
