Equipped with high-resolution cameras and acoustic sensors, AUVs aid in locating and retrieving lost or damaged objects, aiding in recovery missions and increasing the chances of survival in critical situations.
The Future
The next generation of Navy unmanned undersea vehicles, or UUVs, will have automobile hydrogen fuel cell systems. This is thanks to a collaboration between General Motors, the Office of Naval Research, and the U.S. Naval Research Laboratory.
Vehicles fueled by hydrogen fuel cells have higher range and durability than those powered by batteries because hydrogen fuel cells efficiently convert high-energy hydrogen into electricity. Energy is a key component in the Navy’s plans for large displacement UUVs with an endurance of more than 60 days under the ONR’s Innovative Naval Prototype program.
The Prototype
A prototype UUV with a GM fuel cell at its core has just undergone a thorough test by the Naval Research Laboratory. At the Naval Surface Warfare Center in Carderock, Maryland, testing took place in pools as a crucial stage in the creation of an at-sea prototype.
According to Frank Herr, ONR’s department leader for Ocean Battlespace Sensing, “Our in-water experiments with an integrated prototype show that fuel cells can be a game changer for autonomous underwater systems.” “As Navy looks to use UUVs as force multipliers, reliability, high energy, and cost-effectiveness — all brought to us via GM’s partnering — are particularly important.”
The consumption of petroleum and carbon dioxide emissions are two significant environmental issues in the automotive industry that hydrogen fuel cell propulsion technology helps address. Hydrogen produced from renewable resources like wind and biomass that have been saved for later use can power fuel-cell automobiles. The only emission after converting to energy is water vapour. It doesn’t take long to recharge.
The fuel cells made by GM are small and light, and they deliver excellent performance and dependability. By producing in large quantities, costs can be reduced. These qualities align with the Navy’s objectives to create dependable, cost-effective systems.
According to Charlie Freese, executive director of GM Global Fuel Cell Activities, “The collaboration with the Navy leveraged what we learned in amassing more than 3 million miles of practical experience with our Project Driveway fuel cell program.” “Additional lessons we learn about the performance of fuel cells in non-automotive applications will benefit our customers and be useful in GM’s drive to offer fuel cells across consumer markets,” says the statement.
What Distinguishes UUV and AUV From One Another?
Unmanned underwater vehicles (UUV), also referred to as underwater drones, are submersible cars that are capable of operating underwater without a human driver. Remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs) can be used to categorize these vehicles.
Interesting Facts
Underwater vehicles that can function without a human operator are known as autonomous underwater vehicles (AUVs). From a few kilograms to thousands of kilograms, sizes are possible. To do research for the Applied Ph Laboratory at the University of Washington in the Arctic Waters, the first AUV was built in 1957.
Ten various AUVs, including underwater gliders, screw-driven AUVs, and bionic AUVs, had been created by the early 2000s. The most current variants featured automatic buoyancy control, whereas the older types used screw propeller thrusters. The first version, SPURV, weighed 484 kg, could cruise for up to 5.5 hours, and could descend to depths of 3650 meters.
Conclusion
Hydrogen-powered autonomous underwater vehicles are revolutionizing the field of underwater exploration and research. Their ability to operate efficiently, produce zero emissions, and endure long missions has positioned them as game-changers in the industry. From environmental monitoring and resource exploration to offshore infrastructure inspection and search and rescue operations, these AUVs offer unparalleled capabilities that were once unimaginable.
