How plastic debris helps invasive species hitchhike
In addition to posing a pollution problem in marine environments worldwide, plastic debris is also an agent in transporting invasive species to new distributional ranges.
Robot mimics krill in underwater environments
In the lab, researchers achieved the desired speed and kinematics with the RoboKrill and expect to eventually use the robot to explore marine environments.
Video: Slow-moving water and wind tapped by the Big Cajun
The wind-marine hybrid system simultaneously extracts low-cost power from slow moving water and wind.
Video: The implications of ice for offshore wind turbines
Data from indoor ice basin tests inform simulation models to quantify the ice loads on these structures.
Study maps sewage inputs to coastal ecosystems
A global wastewater model and map identify inputs of nitrogen and pathogens across 130,000 watersheds worldwide.
Video: Subsea cable to bring Australian solar energy to Singapore
The Australia-Asia PowerLink will harness Australia’s abundant solar energy resource for transmission to Singapore.
Video: Renewable energy storage on the seafloor
The modular Ocean Battery pumped hydro system is engineered to be located on the seabed near offshore wind turbines or floating solar power plants to store the excess energy produced.
DOE funds wave energy R&D
Selected projects will conduct open-water testing at the PacWave South test site off the Oregon coast.
Video: Maiden voyage of world’s first liquefied hydrogen tanker
The specially built carrier will transport liquified hydrogen generated from brown coal in Australia to Japan.
Anti-corrosive coating developed for steel used in maritime applications
The researchers added silicon (Si) and magnesium (Mg) to the steel, thereby forming an alloyed coating.
Video: Companies launch sea-to-air drone
Equipped with high-quality cameras, the underwater drone can relay data back to the remote operator via KDDI's advanced mobile communication network.
Floating nuclear reactors withstand hurricane-speed winds, dangerous undercurrents
A model of the 60 MW reactors was subjected to winds that reached hurricane speeds along with strong waves and undercurrents. During those tests, the reactors stayed upright, according to the researchers.
Video: New system enables drones to accompany small boats
The V-Line Boat Mode is designed for use along with Volarious’ DJI Mavic 2 drones. Volarious suggests that the system could be used for coastline surveillance and search and rescue applications.
Video: Cleaning the seafloor with robots
An autonomous robotic system is being advanced by European researchers to detect and retrieve litter on the seafloor.
Video: First Seawing kite system to set sail
The system is projected to enable an average 20% reduction in cargo ship fuel consumption and greenhouse gas emissions.
Prolong power cable fatigue life with bend stiffeners
Dynamic cable testing has yielded promising results for extending the fatigue life of cables used in future floating offshore wind applications.
UK and Morocco to connect with world’s longest subsea cable
A 10.5 GW solar and wind farm under construction in Morocco will supply the U.K. with clean energy via subsea cables destined to be the world’s longest.
Hornsea 2 delivers first power
When fully operational, the project's 165 8 MW Siemens Gamesa wind turbines will be capable of generating 1.32 GW of renewable power.
Video: Launch of first hydrogen-based marine propulsion system
A full-scale, full-size, zero-emissions drivetrain powered by hydrogen fuel cells designed for ships and ferries has been tested and verified.
Putting ocean plastic to good use: Powering cleanup vessels
Converting retrieved waste into oil via hydrothermal liquefaction eliminates the need for land disposal of some of the plastic and can markedly reduce shipboard fossil fuel use and attendant emissions.
