Shipping

Transport produces 28% of the greenhouse gas released in the US, and nearly a quarter of that comes from heavy vehicles – more than from passenger cars. Revoy attacks the problem with a smart dolly that creates a hybrid semi truck with two heads.

Methane is awful for the atmosphere. It's a major byproduct of many industrial processes, and we now know it also comes from a surprising and seemingly innocuous source – ships passing through shallow waters.

Once famous for building the world's biggest and most powerful engines, Finnish company Wärtsilä is investing heavily in technology to clean up the notoriously difficult heavy marine sector. CEO Håkan Agnevall lays out a roadmap to zero carbon 2050.

The air at sea might be getting a bit cleaner as technology group Wärtsilä puts its Carbon Capture Solution (CCS) system on the market. The modular apparatus is claimed to capture as much as 70% of the CO2 emissions from cargo ship exhaust systems.

Just last month we trawled the internet for updates to our coverage of the Dynafin propulsion concept from marine giant ABB. Now the technology has been independently tested, which also gives us our first look at the actual system.

Swiss marine giant ABB has spent more than a decade developing a radically different Voith-Schneider take on a marine propeller. The Dynafin system promises up to 85% efficiency, while giving a vessel super-precise maneuvering capabilities.

HyperloopTT is looking to completely redesign the way cargo transport is carried out in Brazil, with an ambitious HyperPort project that carries 40-ft (12.2-m) shipping containers in a partial vacuum tube at speeds rivaling that of flight.

The AT2 Aerospace Z1 airship aims to use a combination of hydrogen propulsion and helium buoyancy to travel over 1,000 miles per trip. It will reach the world's most remote destinations and use proprietary Air Cushion landing gear to touch down.

Singapore's Tuas mega port has now successfully handled 10 million containers since it kicked off operations in September 2022, and is expected to handle 65 million shipping containers a year in the 2040s when its development is complete.

Transporting goods on huge fossil-fueled cargo ships is a dirty business. But one such vessel is about to embark on a pilot that could clean up shipping's act considerably. An onboard system has now been installed on the Clipper Eris that will capture CO2 from its exhaust outlets and store it in tanks.

Most of us are familiar with the vest-clad beagle that hunts for illegal fruits and plants in the travelers' luggage at airports. Now, a species of giant pouched rat has been trained to fulfill a similar role in finding illegal wildlife products.

Volvo has long been a leader in the long-haul heavy-truck category with its FH series. Its 12 to 16-liter diesel "world engine" made excellent power output, lower emissions, and relatively low fuel consumption. Next year, it'll be powered by batteries.
