MAN Energy Solutions tester metan-rensning i Frederikshavn

Den tyske motorfabrikant er i gang med at udvikle et system, der skal reducere metanudslippet fra firetakts-motorer med op til 70 pct. Testen af systemet finder sted på MAN Energy Solutions fabrik i Frederikshavn.

Motorproducenterne har travlt med at investere i løsninger til reduktion af metanudslip fra skibsmotorer, der drives af naturgas, fordi udslippene er inkluderet i livscyklusvurderinger af forbruget i EU´s regler for skibes miljø- og klimabelastninger.

MAN Energy Solutions annoncerede således mandag, at de lancerer IMOKAT II-projektet for at udvikle en efterbehandlingsteknologi til at reducere metanslip fra dets firetaktsmotorer.

Projektet skal undersøge driftserfaringerne med en såkaldt pre-turbo oxidationskatalysator, der er udviklet på MAN Energy Solutions hovedkvarter i Tyskland, men nu testes på virksomhedens anlæg i Frederikshavn.

I modsætning til et tidligere projekt, der var afhængig af meget dyre materialer, bygger det nye projekt på en teknik, der vil gøre den færdige løsning billigere.

“Da der endnu ikke findes nogen kommercielt tilgængelig teknologi på markedet, vil felttesten være første gang nogensinde, at et fartøj sejler med en metankatalysator,” siger Hans-Philipp Walther, der er chef for Exhaust Gas Aftertreatment i MAN Energy Solutions.

En test på et skib i den virkelige verden er planlagt til 1. kvartal næste år, oplyser selskabet.
