利用水的力量在苏格兰海岸4月14日,2023 - 7点故事,环保虽然可能铺平道路,水电有其特定的挑战。它有一个高初始成本,通常可以侵入性和破坏性的当地社区和生物多样性。在所有的可能性,此外,它将变得越来越容易受到干旱。但如果我们可以利用海洋本身的力量?这就是Scotland-based轨道船用动力与它的目标是2 mw + O2。其开发人员说这是世界上最强大的潮汐涡轮机在商业运作和15年的细化的结果。现在,轨道刚刚赢得一个选项协议从苏格兰皇冠房地产新韦斯特雷岛湾的潮汐能源项目。这是一个区域的水在奥克尼群岛,潮汐的速度可以达到3 m / s。添加更多的潮汐涡轮机海洋能源中心低碳能源公司已经部署了一个单位的O2在欧洲海洋能研究中心(EMEC),自2021年7月,向英国电网提供能源。奖后合同的区别(差价合约)——英国政府支持低碳发电的主要机制——从去年分配轮4,这是准备安装三个涡轮机。 The <3 of EU tech The latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art.

Orbital’s floating O2 platform is 243 feet long and placed in tidal streams and moored to the seabed via strong anchors that hold it in place. It is connected to the local electricity grid via a subsea cable. The device catches the powerful streams of water with underwater rotors attached to adjustable legs. Engineering and maintenance can then raise the legs above the surface for easier access. Furthermore, the rotor design can be reversed to adapt to different tide cycles. Part of broader UK net zero strategy Orbital will situate the new part of its Orkney project adjacent to the EMEC. The Option Agreement is for 30MW, which the company says would equate to approximately 12 new O2 tidal turbine devices across the site. Orbital has also confirmed it has the necessary grid connection in place to service the project. Andrew Scott, CEO of Orbital Marine Power, commented on securing the Crown Agreement, stating, “As the UK looks to accelerate the decarbonisation of its energy system, we firmly believe tidal projects can bring unique benefits while harnessing a perfectly predictable and secure source of renewable energy. We’re proud to be building that vision in Orkney with this investment in our Westray Project.” Andrew Scott, CEO of Orbital Marine Energy Last year, Orbital also received strategic investment from Franco-American offshore oil contractor TechnipFMC to “accelerate market scale-up and deployment,” with TechnipFMC becoming a shareholder of the company. Ocean energy could play a big part in energy transition, but needs to scale fast The oceans do indeed have a great deal to offer when it comes to renewable energy. Tidal energy projects have long held significant potential, but is still an as-yet-underdeveloped energy source. In a 2018 report, the IEA named off-shore renewable electricity generation a “ rising force in global energy .” However, it needs to be deployed much more rapidly, hitting a target output of 27.0TWh by 2030 for a net-zero by 2050 scenario. This means it needs to grow at a rate of above 33% per year from now until the end of the decade, which would take several fleets of Orbital’s O2s. But things are picking up. As reported by Power Technology , in the UK in 2022, four projects were awarded contracts for a total of 4.08MW. Encouraging to see positive signals from @energygovuk in their announcement today of a ringfence allowance to support #tidalenergy in AR5 of this year's Contracts for Difference scheme. https://t.co/1YbxIWIrkN Alistair Carmichael, MP for Orkney and Shetland, commented on the new project with Orbital, “These are exciting times for tidal stream energy. Progress with Orbital’s Westray project is a vote of confidence in the potential here in the isles and demonstrates exactly why expanding grid capacity for Orkney has been so important. “This good news is also evidence of the need for a more robust strategy from the government on tidal stream deployment, including continued and expanded backing in the next round of Contracts for Difference funding. We need to continue to ramp up development in the years to come.” With a slew of tidal and ocean energy startups vying for the shores around the UK, perhaps this technology could be one of the keys to non-invasive and unobtrusive reliable renewable energy generation.
