PACECO Corp. has made a significant stride in sustainable port operations by launching the world's first hydrogen-powered rubber-tired gantry (RTG) Crane at the Port of Los Angeles. The RTG Transtainer Crane, named H2-ZE, is a product of collaboration between PACECO Corp. and MITSUI E&S, with funding from the Japanese New Energy and Industrial Technology Development Organization. This groundbreaking initiative is part of the California Hydrogen Hub project, supported by the Department of Energy, which aims to invest up to $15 billion in hydrogen technologies, with a substantial portion allocated for the Port of Los Angeles. The H2-ZE RTG Transtainer Crane features a fuel-cell hydrogen power pack unit, sourced from Toyota, that replaces the previous diesel genset. This innovation allows the crane to operate for up to 16 hours, emitting zero emissions and setting a new standard for environmentally-friendly port operations. Refueling of the crane takes place during the non-operational shift using a mobile refueler with cascade tank switching approach. The deployment of this advanced hydrogen technology not only reduces emissions but also ensures long-term operation, making it a viable solution for port terminals. PACECO Corp.'s pioneering project signifies a significant advancement in the maritime logistics industry's sustainability efforts. The company aims to continue expanding the deployment of its fuel cell power pack concept, paving the way for a more sustainable and environmentally-conscious future in port operations. The successful implementation of the hydrogen-powered crane at the Port of Los Angeles highlights the industry's shift towards green technology and sets a precedent for future hydrogen technology deployments.
