    Sea-to-Air Drone Redefines Offshore Operations
    [​IMG]
    In recent weeks, Japanese telecommunications operator KDDI, commercial drone manufacturer Prodrone, and underwater robotics firm Qysea unveiled the world's first 'Sea-Air Integrated Drone' during a flight showcase at the Hakkeijima Sea Paradise in Yokohama. The revolutionary drone aims to modernize offshore and marine operations with its intelligent capabilities, high working efficiency, and minimized manpower required.

    The technological achievement between KDDI and Qysea has resulted in the first commercial drone capable of operating seamlessly through land, sea, and air. Through long-range mobile communications, the drone is operated remotely to fly to its preset route at sea. After landing at its designated location, the FIFISH ROV is released and deployed to work.
    The pilot is then able to remotely operate with the ROV from a safe working location, and perform a variety of inspection, maintenance, and repair work underwater. For further information see the IDTechEx report on Drone Market and Industries 2021-2041.

    Traditional and widely-used methods in underwater inspections often involve challenges with time, energy, monetary costs, and human risks, where workers would need to use boats to drive out to offshore platforms and make multiple dives for their inspections. The KDDI and Qysea jointly-developed 'Sea-Air Integrated Drone' provides a breakthrough within remote marine-based operational work. Without the need to leave their onshore working location, the operator can deliver inspections with real-time visual feedback and operate through underwater environments with a variety of sampling, measurement, and manipulation tools, as well as be able to live-stream operations for multi-person collaborations.

    The drone has shown it will have far-reaching applications across the various marine-based industries. In offshore wind power, the drone can be deployed to perform complex inspections and maintenance work on its frames and foundations to greatly reduce human risks. In the world of aquaculture, the drone is able to fly out to monitor its livestock and crops, as well as perform maintenance and repair work through the ROV's multitude of add-on tools. Other marine-based applications include operations involving search and recovery, hull inspections, and various other subsea infrastructures.

    With further details of its release coming in early 2022, the drone will undoubtedly lead an essential path towards the development of a sustainable ocean economy and the global goal of carbon neutrality.

    In China's Shandong province, Qysea has recently teamed up with local technology scientists to debut the nation's first unmanned drone and ship for mariculture operations. Utilizing remote communication technologies, aquaculture farmers and scientists can sail out to farms to monitor livestock and crops from a safe onshore location.

    Through the technological collaboration of ocean robotics and artificial intelligence, the unmanned sea vehicle delivers seamless surface-to-underwater control, ultra-clear and real-time imaging feedback, as well as remote autonomous operational capability. With fewer required costs, manpower, and energy, the emergence of compact unmanned ROVs is a great breakthrough in efficiency and sustainability, compared to the traditional methods used in mariculture operations.

    FIFISH PRO V6 PLUS is a compact sized expert in advanced underwater solutions. With a diving depth of 150 meters, an intelligent interface to add on a variety of add-on tools, and the new integration of a Q-motor stabilization system, small-scale underwater operations can be fully optimized.

    The FIFISH PRO V6 PLUS delivers 6 degrees of freedom, allowing the operator to achieve any posture and angle of movement. With the intelligent distance and altitude lock systems, the ROV adapts to unpredictable environments to move with boosted stability.

    Gravity Could Solve Clean Energy’s One Major Drawback
    Finding green energy when the winds are calm and the skies are cloudy has been a challenge. Storing it in giant concrete blocks could be the answer.

    IN A SWISS VALLEY, an unusual multi-armed crane lifts two 35-ton concrete blocks high into the air. The blocks delicately inch their way up the blue steel frame of the crane, where they hang suspended from either side of a 66-meter-wide horizontal arm. There are three arms in total, each one housing the cables, winches, and grabbing hooks needed to hoist another pair of blocks into the sky, giving the apparatus the appearance of a giant metallic insect lifting and stacking bricks with steel webs. Although the tower is 75 meters tall, it is easily dwarfed by the forested flanks of southern Switzerland’s Lepontine Alps, which rise from the valley floor in all directions.

    Thirty meters. Thirty-five. Forty. The concrete blocks are slowly hoisted upwards by motors powered with electricity from the Swiss power grid. For a few seconds they hang in the warm September air, then the steel cables holding the blocks start to unspool and they begin their slow descent to join the few dozen similar blocks stacked at the foot of the tower. This is the moment that this elaborate dance of steel and concrete has been designed for. As each block descends, the motors that lift the blocks start spinning in reverse, generating electricity that courses through the thick cables running down the side of the crane and onto the power grid. In the 30 seconds during which the blocks are descending, each one generates about one megawatt of electricity: enough to power roughly 1,000 homes.

    This tower is a prototype from Switzerland-based Energy Vault, one of a number of startups finding new ways to use gravity to generate electricity. A fully-sized version of the tower might contain 7,000 bricks and provide enough electricity to power several thousand homes for eight hours. Storing energy in this way could help solve the biggest problem facing the transition to renewable electricity: finding a zero-carbon way to keep the lights on when the wind isn’t blowing and the sun isn’t shining. “The greatest hurdle we have is getting low-cost storage,” says Robert Piconi, CEO and cofounder of Energy Vault.


    Without a way to decarbonize the world’s electricity supply, we’ll never hit net zero greenhouse gas emissions by 2050. Electricity production and heat add up to a quarter of all global emissions and, since almost every activity you can imagine requires electricity, cleaning up power grids has huge knock-on effects. If our electricity gets greener, so do our homes, industries, and transport systems. This will become even more critical as more parts of our lives become electrified— particularly heating and transport, which will be difficult to decarbonize in any other way. All of this electrification is expected to double electricity production by 2050 according to the International Atomic Energy Agency. But without an easy way to store large amounts of energy and then release it when we need it, we may never undo our reliance on dirty, polluting, fossil-fuel-fired power stations.

    This is where gravity energy storage comes in. Proponents of the technology argue that gravity provides a neat solution to the storage problem. Rather than relying on lithium-ion batteries, which degrade over time and require rare-earth metals that must be dug out of the ground, Piconi and his colleagues say that gravity systems could provide a cheap, plentiful, and long-lasting store of energy that we’re currently overlooking. But to prove it, they’ll need to build an entirely new way of storing electricity, and then convince an industry already going all-in on lithium-ion batteries that the future of storage involves extremely heavy weights falling from great heights.

    Unique models adopted by Li-ion battery recycling start-ups investigated by IDTechEx
    Wednesday, 12 January 2022
    IDTechEx have identified a variety of business models adopted by recyclers of lithium ion (Li-ion) batteries and have written a new report presenting a detailed analysis of the current Li-ion recycling value chain.

    Recent IDTechEx research has determined that 48 percent of Li-ion battery recyclers are currently operating on a lab- or pilot scale. This is reflective of innovators recognizing the value of recycling in the future circular economy and looking to improve the environmental credentials of electric vehicles. Throughout the 2020s, IDTechEx expects to see numerous Li-ion battery recycling start-ups transition to commercial-scale as global capacity increases to anticipate the availability of end-of-life electric vehicle batteries.
