Since one litre of diesel produces more than 2.5 kg of CO₂, the combined carbon emissions from global fishing operations are huge. Built in 2015, Karoline was the first hybrid fishing vessel equipped with two battery packs of 195kWh as well as a 500-litre diesel engine, which together power the vessel for a full day. Running on diesel to and from the fishing grounds, Karoline switches to electricity for fishing, loading and unloading. It runs electric-only for almost three hours every day, and the batteries are fully recharged in port overnight. The boat’s electrical supply has proven faultless after years of operation.
