Antwerp Terminal Services (ATS), a joint venture between MSC PSA Europe Terminal (MPET) and PSA Antwerp (PSAA), today officially launched the world’s first H2 dual fuel straddle carrier in the Port of Antwerp during a brief ceremony. Using state-of-the-art H2 dual fuel combustion engine technology, developed by cleantech company CMB.TECH and integrated into a straddle carrier with the support of ATS, the machine runs on a mix of hydrogen and diesel. It can therefore play an important role in reducing terminal greenhouse gas emissions.
