德國煉油廠將多余的風能轉化為氫能

據(jù)能源之聲4月27日消息稱，德國北部的一家煉油廠希望將過剩的風能轉化為綠色氫氣，以取代天然氣，并生產用于航空的合成燃料。

如果認為在商業(yè)上可行的話，位于德國最北端的石勒蘇益格-荷爾斯泰因州的30兆瓦綠色氫能試點項目到2030年可能擴大到700兆瓦。氫氣將取代天然氣作為煉油廠運作的原料，還可以用來生產航空用的合成煤油。

該項目由Raffinerie Heide和許多合作伙伴開發(fā)，包括電力公司Orsted和EDF，以及工業(yè)公司蒂森克虜伯。這是去年德國政府入圍的20個項目之一，這使它能夠申請每年1億歐元的融資計劃。

Raffinerie Heide董事總經理Jürgen Wollschl?ger告訴能源之聲：“我們正在等待德國經濟事務和能源部的反饋，可能在今年8月之前。在這一階段，我們不能再就已提交的建議與能源部直接聯(lián)系，但我們相信，我們是最有吸引力的入圍項目之一?！?/span>

該項目的關鍵是利用該地區(qū)風力發(fā)電場產生的多余電力。石勒蘇益格-荷爾斯泰因州的風力發(fā)電裝機產能約為6.6吉瓦，其中大部分在陸上，陸上和海上的裝機產能也在增加。但是，在大風天和需求低迷的日子里，可用的電量會超過所需的電量，甚至超過電網可以吸收的電量。

Wollschlger 表示：“該地區(qū)有大量的綠色電力供應，主要是岸上的風能。去年，40%的發(fā)電量被削減，使德國納稅人損失了約3.5億歐元。我們的想法是用這些多余的電來生產綠色的氫。因此，我們希望免除一些通常強加給最終用戶的稅收?！?/span>

如果大規(guī)模開發(fā)，該項目每年將能生產10萬噸氫氣。

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.
