据OE网站9月7日报道，风力涡轮机制造商西门子歌美飒周二表示，该公司在其位于丹麦奥尔堡的叶片工厂生产出了世界上首枚可回收的风力涡轮机叶片。
该公司称，风电是应对气候紧急情况的基石之一。全球风能委员会预计到2030年将安装超过200吉瓦的海上新装机发电量，因此快速引入可回收解决方案至关重要。
第一批81米长的可回收叶片，称为可回收叶片，现已准备在海上商业使用。
西门子歌美飒表示，有了这项技术，叶片中的材料可以在其使用寿命结束时分离，从而可以循环利用到新的应用中，从而确定可持续发展的下一个里程碑。风力涡轮机的许多部件，如风塔和风舱部件，都已建立了回收实践。到目前为止，用于风力涡轮机叶片的复合材料在回收利用方面更具挑战性。西门子歌美飒可回收叶片以成熟可靠的工艺为基础，打破了这一模式，是同类产品中的第一款，能够在其生命周期结束时实现回收，并为未来项目的完全可回收性成为市场需求铺平了道路。
据风力涡轮机制造商介绍，这些可回收的涡轮机叶片将在德国RWE的Kaskasi海上风电场安装和监控。Kaskasi预计将于2022年投产。
除了RWE之外，西门子歌美飒还与法国电力可再生能源公司(EDF Renewables)和wpd合作，旨在在他们未来的海上风电场部署几套可回收叶片。
虽然可回收叶片现在已经准备好部署，但西门子歌美飒不希望止步于此。这家风力涡轮机制造商还设定了一个目标，到2040年，不仅要制造叶片，还要制造完全可回收的涡轮机。
西门子歌美飒质量管理与健康、安全和环境主管Gregorio Acero表示，我们的愿望是生产可以产生20-30年可再生电力的风力涡轮机。当它们的使用寿命结束时，我们可以分离材料并将它们用于新的相关应用。可再生叶片是朝着这个方向迈出的重要一步，远远领先于我们2040年的目标。

World's First: Siemens Gamesa Makes Recyclable Offshore Wind Turbine Blades
Wind turbine maker Siemens Gamesa said Tuesday it had made the world’s first recyclable wind turbine blades at its blade factory in Aalborg, Denmark.
"Wind power is align="justify"> The first 81-meters recyclable blades, called RecyclableBlades, are now ready for commercial use offshore.
"With this technology, separation of the materials in the blade is possible at the end of its lifetime, enabling recycling into new applications and thereby defines the next milestone in sustainability," Siemens Gamesa said.
"Many components of a wind turbine, such as the tower and nacelle components have established recycling practices. Until now, the composite materials used in wind turbine blades have been more challenging to recycle," the company said.
Siemens Gamesa says that its wind turbine blades are made from a combination of materials cast together with resin to form a strong and flexible lightweight structure.
"The chemical structure of this new resin type makes it possible to efficiently separate the resin from the other components at end of the blade’s working life. This mild process protects the properties of the materials in the blade, in contrast to other existing ways of recycling conventional wind turbine blades. The materials can then be reused in new applications after separation," the company said.
"Built align="justify"> According to the wind turbine maker, these recyclable turbine blades will be installed and monitored at RWE's Kaskasi offshore wind farm in Germany. Kaskasi is expected to go align="justify"> Apart from RWE, Siemens Gamesa is working with EDF Renewables and wpd with the aim to deploy several sets of RecyclableBlade at their future offshore wind farms.
While the recyclable blades are now ready for deployment, Siemens Gamesa doesn't want to stop there. The wind turbine manufacturer has also set a goal of making not just blades, but also turbines fully recyclable by 2040.
"Our aspiration is to produce wind turbines that can generate renewable electricity for 20-30 years. When they reach the end of their useful life, we can separate the materials and use them for new relevant applications. The RecyclableBlade is a great step in that direction and well ahead of our 2040 goal,” said Gregorio Acero, Head of Quality Management & Health, Safety, and Environment at Siemens Gamesa.
