FacebookTwitterLinkedInEmailPrint分享Recharge:Rare-earth-free permanent magnet generators (PMG) for offshore wind turbines with nameplates of 20MW are expected to be a reality “within three years,” following trials of a new-generation concept at the UK Offshore Renewable Energy (ORE) Catapult facility.A 250kW version of the axial-flux design being developed by GreenSpur Wind, which uses ferrites – an iron-rich ceramic – for its magnets, would be part of a four-module 1MW unit that is foreseen to be scalable to a power rating roughly twice that of the biggest PMGs in service today.“It was our intention from the outset to design a generator that could be scaled for the next generation of offshore wind turbines,” said Hugh-Peter Kelly, GreenSpur’s head of technology and the inventors of the design. “The feedback that we’ve received is that current designs have known limitations and new concepts will be needed to deliver next generation 20MW offshore wind turbines.”GreenSpur is now moving forward with modelling for “significantly bigger, multi-megawatt generators”, with the target of designing a 12MW-plus concept for offshore turbine created by “stacking” three 4MW units in parallel.Replacing high-price rare-earth materials with ferrites – a waste material produced in steel-making – would cut the cost of PMG magnets from £40/kg ($50/kg) to around £1/kg, according to GreenSpur calculations, meaning the design could carve around 33% out of the capital cost of direct-drive generator, and so almost 5% off the price of a turbine.More: Offshore wind turbine 20MW generator ready ‘within three years’ U.K. company sees potential for 20MW offshore wind turbine within three years
Brisbane landlords are working harder to secure a tenant according to the latest vacancy rate numbers. Photo: Paul GuyTHE latest analysis by SQM Research showed Brisbane is among the toughest capital city markets in the nation for securing a tenant.Vacancy rates are a measures the percentage of the total residential rental pool that was vacant during a set time frame, with a rate above three per cent indicating a market is tipping to the tenant’s favour.More from newsParks and wildlife the new lust-haves post coronavirus1 day agoNoosa’s best beachfront penthouse is about to hit the market1 day agoSQM released figures that showed the national residential vacancy rate across all capital cities was 2.2% in September 2017.A breakdown showed Brisbane’s vacancy rate of 3.2 per cent was second only to Perth, which had a rate of 4.5 per cent for the period.The Brisbane result reflected a rise on the September 2016 figure of 2.9 per cent and showed an increase of 0.1 per cent on the August 2017 figure.Australia wide, it was Hobart’s vacancy that had landlords most comfortable with a 0.4 per cent result for the month.In the bigger capitals, vacancies rose in Sydney to record 2.1 per cent in September, while Melbourne saw its rate rise to 1.9 per cent in the month.Follow Kieran Clair on Twitter at @kieranclair
