Electric Water Vehicles

Uncrewed survey and inspection vehicle takes on the booming offshore wind market. The vehicle will exploit the strong demand for accurate ocean mapping, especially within the booming offshore wind market.

Oranje Nassau, a 20-meter, 55-passenger sightseeing boat and water taxi operating on Berlin's urban waterways was recently put back into service after replacing its diesel engine with a fully integrated all-electric propulsion system by Torqeedo.

Following two years of design, construction and AI model training, the Mayflower Autonomous Ship was officially launched in September 2020. With no human captain or onboard crew, this is the first self-directed autonomous ship with technology that is scalable and extendible to traverse the Atlantic Ocean.

Avikus, a subsidiary of HD Hyundai, has successfully carried out autonomous navigation of a large ship across the ocean, becoming the first company in the world to accomplish such a feat. In this ocean crossing, the Prism Couragr equipped with HiNAS 2.0 was operated autonomously on the optimal routes, increasing the fuel efficiency by around 7 percent while reducing greenhouse gas emissions by about 5 percent. Also, the system accurately recognized the locations of nearby ships during operation to avoid collision about 100 times.

Echandia has received an initial order for battery systems in the highly specialized naval segment. The order, which comes from major system supplier in the maritime sector, amounts to EUR 5 million and is Echandia's first foray into military applications.

Globally, the pH of the ocean is decreasing as humans burn coal, oil and gas. When carbon dioxide from these activities is absorbed by the ocean, it affects the ability of marine organisms to build and maintain their shells and may also change the behavior of some fish.

This IDTechEx premium article provides an update on electric leisure boating and electric ship markets in 2022. Drivers and data behind the recent surge in leisure boating sales are explained, with breakdowns by power class and commentary on future expectations. In the commercial and industrial (C&I) shipping sector, ferries have long been the low hanging fruit and remain the most common electric vessel type in-service, but regulations are driving change. Behemoth battery packs installed on a small number of giant sea-going vessels are expected to take over and dominate maritime battery demand within ten years.

Auckland harbour ferries are set to get quieter, cleaner and greener, thanks to two new fully-electric ferries for commuters and sightseers to travel on. Auckland Transport will operate the two electric fast ferries across all major inner and mid-harbour services, and the new ferries will provide a pathway for further ferry electrification in the future.

Current Direct is demonstrating a swappable battery solution for powering inland waterway vessels, with one or more lithium-ion batteries installed in a swappable container, or e-house. Project estimates indicate that the use of swappable batteries connected to an energy-as-a-service platform could reduce European water transport emissions by 482 000 metric tonnes of CO2 equivalents each year.
