Tidal Energy in Scotland - “The Crown Jewel of The Pentland Firth”
Construction will soon begin on what is to be the largest tidal turbine energy project in Europe, following the Scottish government’s official approval of the concept and construction plans. The tidal stream project let by MeyGen Ltd. is at the forefront of world tidal energy development and will harvest the tidal resource from the strong tidal streams present along the Pentland Firth in an area that lies in the channel between the island of Stroma (part of the Orkney chain of islands) and the northeasterly tip of the Scottish mainland, encompassing almost 3.5km2 of fast flowing water. MeyGen’s goal is to deliver a fully operational, 398MW renewable energy plant powered purely by the tide, generating the equivalent electricity to power around 40,000 Scottish homes by 2020.
Pelamis P2 – How the Wave Energy Converter Operates
The Pelamis P2 is the second-generation Pelamis Wave Energy machine and includes a number of significant design improvements. The P2 design has been sold to utility customers E.ON and ScottishPower Renewables and are currently being tested for a number of commercial scale projects. At 180m long, 4m diameter and weighing around 1350 tons (mostly sand ballast), the P2 Pelamis is wider, longer and heavier than the P1 design machine. This allows the Pelamis to capture more energy while substantially reducing the cost per MW. Comprised of five tubes with four joints, the P2 has an extra tube section and an extra power module. An improved power take off system for the P2 allows higher efficiencies, enhanced control resolution and increased reliability.
Aubin Brings its Gel Based Products to Brazil
Although the Scottish chemical technology company Aubin originally specialized as a cement and stimulation additive supplier, it has made strong inroads into the Oil and Gas industry in recent years, with the subsea sector being their main target. The company is based in Ellon, Aberdeenshire and has been in business since 1987. Some 6 years ago they came up with a novel product, which came to be known as “gel with a memory”. It is mainly used for pipe pigging purposes as it can be squashed but returns to its original shape. Named L-gel, the product is also used for risers, which are considered impossible to be pigged. It can go around tight bends and through blocked areas where a conventional pig would probably get stuck.
