21.02.2021 Increasing battery and fuel cell power with quantum computing
DLR is using a quantum computer to simulate electrochemical processes in batteries and fuel cells. Focus: Energy, digitalisation, quantum computing, energy storage, energy efficiency, hydrogen.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is conducting research into new materials for more powerful batteries and fuel cells. DLR scientists are now using a quantum computer to simulate electrochemical processes within energy storage systems. This makes it possible to design the materials used in such a way that the performance and energy density of batteries and fuel cells increase significantly.

The modern world more and more relies on information exchange using data transfer technologies.
Private and secure communications are fundamental for the Internet, national defence and e-commerce, thus justifying the need for a secure network with the global protection of data. Information exchange through existing data transfer channels is becoming prone to hacker attacks causing problems on an international scale, such as interference with democratic elections, etc.
In reality the scale of the hacking problem is continual, in 2019 British companies were reportedly hit by about 5,000 ransomware attacks that paid out more than $200 million to cyber criminals [1]. During the first half of 2020, $144.2 million has already been lost in 11 of the biggest ransomware attacks [2]. Communications privacy is therefore of great concern at present.

A new APP knock-in mouse has hit the scene. Researchers led by Pascal Sanchez, Denali Therapeutics, San Francisco, California, described the details in a paper posted to bioRxiv on January 20. They humanized the Aβ sequence in the mouse APP gene and knocked in three familial Alzheimer’s disease mutations: Swedish, Arctic, and Austrian. TREM2 expression and cytokine concentrations spiked in brain tissue, microglia flocked to plaques, neurites swelled, and tau and neurofilament light collected in their cerebrospinal fluid. Notably, microglia surrounding plaques seemed distressed the cells filled with lipids and revved up transcription of genes previously linked to a subset of microglia isolated from AD brain tissue. Denali, in collaboration with the Jackson Laboratory, will make this model open access for academics and companies alike.
MAHEPA consortium marks latest flights of HY4 fuel cell hybrid electric aircraft
The MAHEPA consortium announced that technology developed as part of the project has been successfully proven in flight on board the Hy4 fuel cell hybrid electric aircraft (earlier post).
The sixth-generation of hydrogen propulsion has been completely revised from 2016 to 2020, according to aviation requirements. As part of the test campaign launched in November 2020, there have been more than 30 take-offs and flights of up to two hours.
The experience with the sixth-generation drive and the modular structure of the fuel cell would support both air taxi applications with 1.5 hours flight duration as well as an aircraft with up to 40 passengers and a range of up to 2000 km (1200 miles).
COLOGNE, Germany (DLR PR) On 17 December 2020, the US National Aeronautics and Space Administration (NASA) and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) extended their framework agreement on bilateral cooperation for a further ten years.
The agreement was signed by NASA Administrator, Jim Bridenstine, Chair of the DLR Executive Board, Professor Anke Kaysser-Pyzalla, and Member of the DLR Executive Board and Head of the DLR Space Administration, Walther Pelzer, who met via video conference to mark the occasion.
“Groundbreaking and exciting research. This is the result of the long-standing collaboration between DLR and NASA. I am delighted about the continuation of this successful cooperation,” said Kaysser-Pyzalla, following the meeting.
