据能源之声4月27日消息称，德国北部的一家炼油厂希望将过剩的风能转化为绿色氢气，以取代天然气，并生产用于航空的合成燃料。
如果认为在商业上可行的话，位于德国最北端的石勒苏益格-荷尔斯泰因州的30兆瓦绿色氢能试点项目到2030年可能扩大到700兆瓦。氢气将取代天然气作为炼油厂运作的原料，还可以用来生产航空用的合成煤油。
该项目由Raffinerie Heide和许多合作伙伴开发，包括电力公司Orsted和EDF，以及工业公司蒂森克虏伯。这是去年德国政府入围的20个项目之一，这使它能够申请每年1亿欧元的融资计划。
Raffinerie Heide董事总经理Jürgen Wollschl?ger告诉能源之声：“我们正在等待德国经济事务和能源部的反馈，可能在今年8月之前。在这一阶段，我们不能再就已提交的建议与能源部直接联系，但我们相信，我们是最有吸引力的入围项目之一。”
该项目的关键是利用该地区风力发电场产生的多余电力。石勒苏益格-荷尔斯泰因州的风力发电装机产能约为6.6吉瓦，其中大部分在陆上，陆上和海上的装机产能也在增加。但是，在大风天和需求低迷的日子里，可用的电量会超过所需的电量，甚至超过电网可以吸收的电量。
Wollschlger 表示：“该地区有大量的绿色电力供应，主要是岸上的风能。去年，40%的发电量被削减，使德国纳税人损失了约3.5亿欧元。我们的想法是用这些多余的电来生产绿色的氢。因此，我们希望免除一些通常强加给最终用户的税收。”
如果大规模开发，该项目每年将能生产10万吨氢气。

German oil refinery to convert unused wind into fuels
An oil refinery in northern Germany wants to turn excess wind power into green hydrogen to replace natural gas and produce synthetic fuels for aviation.
The 30 MW green hydrogen pilot project in Schleswig-Holstein – Germany’s northernmost state – could be scaled up to 700 MW by 2030 if it is considered commercially viable. The hydrogen would replace natural gas as feedstock to power the refinery’s operations and could also be used to produce synthetic kerosene for aviation.
The project is developed by Raffinerie Heide and a number of partners including power companies Orsted and EDF as well as industrial company Thyssenkrupp. It was among 20 projects shortlisted by the German government last year, which enables it to apply for funding under a €100 million per year financing package. The project’s final proposal was submitted to the government earlier this year and is now awaiting approval.
“We are waiting for feedback from the German ministry of economic affairs and energy, possibly by August this year. At this stage we can no longer be in direct contact with the ministry in relation to the proposal we’ve submitted, but we believe we are amongst the most attractive shortlisted projects,” Jürgen Wollschl?ger, managing director of Raffinerie Heide, told Energy Voice.
Key to the project is to use excess electricity produced by wind farms in the area. Schleswig-Holstein has around 6.6 GW of installed wind power capacity, mostly onshore, and more capacity is being built both onshore and offshore. However, on windy days and on days with low demand, there is more electricity available than needed or more than the grid can absorb.
“There is plenty of access to green electricity in the area, mostly onshore wind. Last year, 40% of the electricity produced was curtailed, costing the German tax payer around €350m. The idea is that we would use that excess electricity to produce green hydrogen. For that reason we are hoping to be exempted from some of the taxes and levies usually imposed on end-users,” said Wollschl?ger.
If developed at a large scale, the project would be capable of producing 100,000 tonnes of hydrogen per year.
