据阿拉伯贸易新闻社2021年5月31日慕尼黑报道，德国西门子交通集团日前与德国埃尔朗根-纽伦堡大学赫尔姆霍尔茨可再生能源研究所签署了一项协议，共同研究在轨道交通中使用液态有机氢载体(LOHC)技术。
作为一个减少二氧化碳排放和帮助实现气候目标的解决方案，在铁路运输中使用氢技术正变得越来越重要。近几年来，西门子交通集团开发了一种氢动力火车Mireo Plus H。在这种技术中，氢以气体形式储存，必须保持在高压下，以实现所需的高密度。
埃尔朗根-纽伦堡大学赫尔姆霍尔茨可再生能源研究所是所谓的LOHC技术领域的领导者。在这个过程中，一个有机载体液体吸收氢，氢只有在需要时才释放。因此，氢在化学上受到束缚，不能以气体形式逸出。通过这种方式，氢可以安全地准备和储存，并廉价的运输，不再需要在高压或低温下储存。该技术的一个特殊优势是，LOHC也适用于火车等移动应用中的车载发电。
西门子交通集团轨道车辆首席执行官Albrecht Neumann表示：“西门子交通集团非常高兴能够与著名的埃尔朗根-纽伦堡大学赫尔姆霍尔茨研究所建立合作关系，共同开发轨道交通领域的液态有机氢载体技术。氢技术是一个很有前途的解决方案，使铁路运输呈现对环境的友好中性。由于可持续性对我们西门子交通集团来说是一个优先考虑的问题，因此我们提供了一个Vectron火车头来测试LOHC技术。”
埃尔朗根-纽伦堡大学赫尔姆霍尔茨可再生能源研究所主任Peter Wasserscheid教授说：“西门子交通集团对LOHC技术的兴趣是我们在过去几年中在埃尔朗根-纽伦堡弗里德里希-亚历山大大学和HI ERN的决定性发展，这是未来可能合作的良好基础。我们与西门子交通集团有共同的愿景，即开发一种氢技术，利用现有的燃料基础设施为火车等大型车辆提供动力。”
通过向赫尔姆霍尔茨研究所提供西门子交通集团的Vectron干线机车，双方有机会共同展示LOHC概念的可行性。

Liquid hydrogen technology for rail transport planned
Siemens Mobility and the Helmholtz Institute Erlangen-Nuremberg for Renewable Energy have signed an agreement on joint research for the use of Liquid Organic Hydrogen Carrier (LOHC) technology in rail transport.
The use of hydrogen technology in rail transport is becoming increasingly important as a solution for reducing CO2 emissions and helping to meet climate targets. In recent years, Siemens Mobility has developed a hydrogen-powered train, the Mireo Plus H. In this technology, hydrogen is tanked in gas form and must be kept under high pressure in order to achieve the required high density.
The Helmholtz Institute Erlangen-Nuremberg for Renewable Energy (HI ERN) is a leader in the field of so-called LOHC technology. In this process, an organic carrier liquid absorbs hydrogen and releases it only when needed. The hydrogen is thus chemically bound and can’t escape in a gas form. This way, it can be prepared and stored safely, and transported inexpensively. Storage under high pressure or at low temperatures is no longer necessary. A special advantage of the technology is that LOHC is also suitable for the on-board generation of electrical power in mobile applications like trains.
Albrecht Neumann, CEO Rolling Stock, Siemens Mobility said: “Siemens Mobility is especially pleased to be entering into a partnership with the renowned Helmholtz Institute Erlangen-Nuremberg to develop Liquid Organic Hydrogen Carrier technology in rail transport. Hydrogen technology is a promising solution for making rail transport climate-neutral. And since sustainability has a very high priority for us at Siemens Mobility, we’re providing a Vectron locomotive for testing the LOHC technology.”
Prof. Dr. Peter Wasserscheid, Director at the Helmholtz Institute Erlangen-Nuremberg for Renewable Energy, said: “Siemens Mobility’s interest in the LOHC technology that we’ve decisively developed over the past few years at the Friedrich-Alexander-University Erlangen-Nuremberg and at the HI ERN is an excellent basis for a possible cooperation in the future. We share with Siemens Mobility the vision of developing a hydrogen technology that uses the existing fuel infrastructure to power large vehicles like trains.”
Through the prospect of providing the Helmholtz Institute with a Vectron mainline locomotive from Siemens Mobility, the two partners have the opportunity to work together to demonstrate the feasibility of the LOHC concept.
