TEMA motors and generators are extremely reliable and robust, and they demonstrate all the advantages of permanent magnet technology in marine propulsion systems. The amount of energy saved by using advanced electric propulsion is impressive, as you sail quietly, without vibrations or impacting the environment by releasing greenhouse gases.
TEMA marine propulsion system is optimal for direct drive, where all the advantages of electric propulsion are most obvious. There is no gearbox, clutch or belt drive. This simplifies the installation and increases the complete boat efficiency.
Standardized motors provide convenient mechanical power for industrial use. The largest are used for ship propulsion, pipeline compression and pumped-storage applications with output exceeding 100 megawatts.
An electrically powered spacecraft propulsion system uses electric motor technology to propel spacecraft in outer space. Most systems are based on electrically accelerating propellant to high speed, while some systems are based on electrodynamic tethers principles of propulsion to the magnetosphere.
In the container, the electricity produced by the fuel cell flows to a separate rack of power inverters, which change the direct current power to alternating current. That electricity then goes into a transformer, shaped like a chest freezer, and then over to a dozen power outlets on the external wall. A suitcase-size battery, charged by the fuel cell, runs the fans that cool the container and vent any hydrogen that leaks from the tanks.
That process involves splitting water into hydrogen and oxygen by using electricity, ideally from renewable sources such as wind and solar power. Electrolysis facilities are growing in number, particularly within renewables-rich Europe, but not yet at the rate needed to supply tens of thousands of ships.
You can already enjoy silent and emission-free cruising, maneuvering and on-board power with our entry solution. Comfort hybrid is configured with small-sized batteries, small electric motors and small diesel gensets. Even with small sized batteries, emission free anchoring is assured.Setup:
The Voith Schneider Propeller (VSP) is a combined propulsion and steering system. Thanks to its short response times to steering commands, it facilitates rapid, safe and precise maneuvering even in adverse conditions.The new electric Voith Schneider Propeller (eVSP) combines these strengths with innovative, emission-free propulsion technology, thus contributing significantly to even more resource-conserving shipping.
We are proud to be able to showcase the world's first fully electric and self-propelled container ship. It will cut 1,000 tonnes of CO2 and replace 40,000 trips by diesel-powered trucks a year, says Svein Tore Holsether, CEO of Yara.
Yara Birkeland, which has already received wide coverage in Norwegian and international media, has been developed in collaboration with the Kongsberg Group (KONGSBERG). The ship was built by VARD with financial support from Enova, and will be in commercial operation from 2022. We have been looking forward to this day for a long time. Yara Birkeland will transport mineral fertilizer between Porsgrunn and Brevik and will contribute to significant emission cuts during transport. This is an excellent example of green transition in practice, and we hope this ship will be the start of a new type of emission-free container ships. There are a lot of places in the world with congested roads that will benefit from a high-tech solution like this, says Holsether.
Now begins a two-year testing period of the technology that will make the ship self-propelled, and finally certified as an autonomous, all-electric container ship.A shared ambition
On the way to a low-emission society, transport emissions must come down to almost zero. To achieve that, we need projects that can transform the market - projects that have the potential to pave the way for others and increase the pace of change in their sector. This is exactly what we believe the world's first autonomous and all-electric container ship will do, says Nils Kristian Nakstad, CEO of Enova. 2b1af7f3a8
