Magnetocaloric effect for more efficient hydrogen liquefaction
Hydrogen will play a key role in the transformation towards a carbon-neutral society. By comparison with current usage, it is estimated that global hydrogen requirements will increase fivefold by 2050 to some 550 million tons. But in order to store hydrogen, enormous amounts of energy are needed. During liquefaction, approximately a third of the energy content of hydrogen is lost, which makes the process largely uneconomical. In the Horizon Europe project HyLICAL with a budget of about some five million euros, a team including the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Darmstadt and the start-up MAGNOTHERM wants to significantly improve the technologies for storing liquid hydrogen. To this end, the team is building on magnetocaloric materials that change their temperature when they are exposed to a magnetic field.

Ein neuartiges, nachhaltiges Herstellungsverfahren für Permanentmagnete
2022/11/25
Projekt Scale2PM der TU Darmstadt gemeinsam mit Fraunhofer IWKS gestartet
Permanentmagnete auf Basis von Seltenen Erden (SE) erhöhen u.a. die Effizienz von Generatoren in Windkraftanlagen und Motoren in Elektrofahrzeugen signifikant. Sie sind somit für eine erfolgreiche Energiewende unerlässlich. Doch die Versorgung und der Abbau von SE wird von der EU als sehr kritisch eingestuft. An diesem Punkt setzt das aktuell gestartete Projekt Scale2PM der Technischen Universität Darmstadt gemeinsam mit der Fraunhofer-Einrichtung für Wertstoffkreisläufe und Ressourcenstrategie IWKS an: Ziel ist es, ein neuartiges Herstellungsverfahren zu validieren, um Permanentmagnete mit besseren oder gleichwertigen Eigenschaften bei verringertem Ressourceneinsatz zu produzieren.
