This #innovative #underwater #kite designed by #Minesto, flies through the waves to generate #clean #energy. The design of #underwater #kites involves creating rigid-wing kites with attached #turbines to harness power from #ocean #currents. These kites move in figure-eight patterns underwater, amplifying energy output by moving faster than the current. The #wings of the kite use #hydrodynamic lift to propel forward, while turbines generate energy fed through a #cable. Different designs exist, such as tethering kites to the #ocean #floor or a #floating #system. Companies like #Minesto and research teams from universities like #North #Carolina #State #University have been at the forefront of developing these innovative energy solutions. The kites are designed to operate in low-velocity tidal and ocean currents, offering a promising #renewable #energy source with significant potential for clean energy production. source - ecomedy #sustainableinnovation #greentechnology #greentech #sustainableenergy #waveenergy #tidalenergy #tidalpower #solarenergy #renewableenergyisthefuture #renewableenergy #solarpowered

In the ongoing battle against climate change, it's essential to explore innovative solutions. Mineralization is a unique way to store CO2 developed by Carbfix in Iceland. It is tried and tested and is actively being scaled up. Get inspired and get new insights on carbon mineral storage technology when Kristinn Ingi Larusson, Head of Business Development and Commercialization at Carbfix, takes the stage at The Danish Offshore Technology Conference 2023. "Turning CO2 into stone is more than managing emissions; it's the path to transforming challenges into solutions and collectively striding towards climate recovery", says Kristinn Ingi Larusson. Join us November 14-15, 2023, when we set the agenda on how innovation and sustainability in the offshore sector contribute to the energy transition and connect the dots between the many initiatives that have been launched: Energy islands, windmill parks, carbon storage, and future technologies such as PtX.

Eels are captivating creatures, and we’re all excited to be able to work with them again. Fish passage testing is a critical step in the development and widespread adoption of FishSafe sustainable hydropower. After extensive computer modeling and computational fluid dynamics testing, we use live fish to validate our exceptionally FishSafe high-performance turbines. We are currently testing with American eels (Anguilla rostrata), which are closely-related to European eels (Anguilla anguilla) and Japanese eels (Anguilla japonica). They are catadromous species, meaning that they spawn in the ocean and then migrate up freshwater rivers and creeks. When fully grown, they migrate back downstream, often extremely long distances, to the ocean to reproduce. All three of these species are rapidly declining, however, and one threat to their survival is hydropower dams, which can block both their upstream and downstream movement. Downstream passage, in particular, is a problem for eel, because fish exclusion techniques that may work for other species do not necessarily work for eel. Compared to other species, for example, relatively large eels are able to pass through screens and enter turbine intakes. And unlike species that travel downstream as juveniles and upstream as adults, eels migrate downstream at their largest size. That’s where FishSafe turbines come in. Last year, we published a study that found 100% immediate and 48-hour survival of American eel passing through our Restoration Hydro Turbine (RHT) design (https://lnkd.in/e-v5vDNq). Many of the eel we tested were longer than the turbine diameter, and the turbine was operating at 667 rpm. Our work since then has confirmed that eel are particularly well-suited to pass safely through our RHT designs. This is great news for eel, for the hydro community, and for all of us who rely on our riverways for food, fresh water, and clean energy. Hydropower is an essential component of achieving a zero-carbon future, and by investing in sustainable technologies and practices, we can create a harmonious balance between reliable, renewable energy generation and the preservation of our planet's biodiversity. #HydroDay #sustainablehydropower #hydropower #sustainableenergy #renewablenergy #cleanenergytransition #aquatic #biodiversity #eel #fishpassage #turbines #environmentalcompliance

Climeworks started Mammoth, the largest Direct Air Capture (DAC) plant in the world this week. Unlike conventional carbon capture which sucks carbon off the exhaust stream of a carbon intensive process such as a natural gas power plant, DAC sucks CO2 right out of air and is in theory carbon negative (removes more CO2 than the CO2 emitted in powering it). While the largest yet, Mammoth removes the equivalent of 8600 cars worth of emission (36,000 metric tons of CO2 per year), which to say the least is extremely tiny. We added 37 billion metric tons to the atmosphere in 2023! But it's a start. The technology however, has been controversial from the start. While IEA states artificial sequestration is much needed if we want to keep whatever slim chance we have to stay within 1.5 deg C. Others are not so optimistic, citing lack of conclusive efficacy data, distraction from the real goal - which is to cut emissions and large capex which will be funded from tax payer subsidies and credits. To top it all, the offsets for this project are costing a whooping $1500 per ton of CO2 removed! They are really need to be $100 or lower for companies to have serious interest. Still large DAC projects are on the horizon for the coming decade and we would know sooner or later whether this one is here to stick or yet another over zealous climate tech which couldn't keep up to it's hype. #cleantech #carboncapture #DAC

Exciting news in wind-assisted shipping! We're excited to be part of the groundbreaking research project KSP WIND, led by the esteemed Norwegian research organization SINTEF Ocean! 🇳🇴 Under the auspices of The Research Council of Norway, this project is set to revolutionize the future of wind-powered ships. At Norsepower, we've long championed the potential of auxiliary wind propulsion, and our partnership with SINTEF Ocean in KSP WIND reinforces our commitment to advancing sustainable shipping practices. 🌱 With funding secured until 2027, this project will develop cutting-edge simulation tools to analyze every aspect of wind-powered vessels, from aerodynamics to operation. We're proud to have demonstrated to the world that wind propulsion makes commercial sense, with meaningful fuel savings of up to 70% achieved in collaboration with our valued customer Sea-Cargo AS! 🛳️ Now, it's time to translate our experience into knowledge that can benefit the wider industry and accelerate the decarbonization of shipping. 💡 We're excited to collaborate with such exceptional partners – including SINTEF, NTNU, Sea-Cargo, and others – who share our vision and drive to create a future where a larger portion of the maritime industry propulsion comes from the wind, both in newbuilds and as retrofits. Together, we're charting a course towards a greener, more sustainable shipping industry.

Solutions are coming 👏👏 The "world's largest" plant designed to suck planet-heating pollution out of the atmosphere like a giant vacuum began operating in Iceland on Wednesday. "Mammoth" is the second commercial direct air capture plant opened by Swiss company Climeworks in the country, and is 10 times bigger than its predecessor, Orca, which started running in 2021. Direct air capture, or DAC, is a technology designed to suck in air and strip out the carbon using chemicals. The carbon can then be injected deep beneath the ground, reused or transformed into solid products. Climeworks plans to transport the carbon underground where it will be naturally transformed into stone, locking up the carbon permanently. It is partnering with Icelandic company Carbfix for this so-called sequestration process. The whole operation will be powered by Iceland's abundant, clean geothermal energy. https://cnn.it/4byajDL #cnn #solution #carbon #sdg13 #climatechange #innovation
