Microorganisms to transform CO2 into sustainable fuel

The ReMeSh research project will increase our understanding of microorganisms' ability to convert CO2 into methane and it will form the basis for development of a new technology for efficient production of sustainable fuel.

What should we do about the enormous flow of data from the city floating around on the internet? How do we find connections and patterns that can transform into useful insights for the authorities, businesses, the police, hospitals and, not least, the people living in the city? The answer is artificial intelligence, and researchers from Aarhus University will lead the european technology development in the coming years.

Artificial intelligence to make European cities smarter

In a major EU project, researchers from Aarhus University will develop brand new technologies to process and analyse image and audio sensor data from cities. This will increase security for citizens and enhance traffic flow.

"Polyester accounts for half of all clothes fibres in the world. Therefore, we will further develop technology based on chemical purification to recycle the polyester materials so that they can return to the textile industry,” says Anders Lindhardt from Danish Technological Institute who's part of the project.

Grand textile project to make Denmark circular frontrunner

A new innovative project aims to redraw the boundaries for fashion design, recycling technologies and consumer behaviour. Worn, damaged or new clothes that are discarded will be broken down into new raw materials and included in a circular economy.

"Evolution has come up with some quite inspiring solutions during the ages, and there's a lot to be gained in a geotechnical perspective," says Assistant Professor Hans Henning Stutz, one of the scientists behind the new research. Photo: Colourbox.

New research: Snakeskin can inspire to safer buildings

It might be a good idea to look for inspiration in nature when designing load-bearing foundations for buildings. Researchers from Aarhus University and University of California Davis have found a significantly increased load-bearing capacity for piles when using snakeskin as surface inspiration.

Liming on acidic soils reduces nitrous oxide emissions and increases yields

Researchers from Aarhus University and the Norwegian University of Life Sciences have found that when farmers apply lime to acidic fields, they can not only increase crop production, but also reduce nitrous oxide emissions and increase the soil capacity to oxidize methane, thereby contributing to climate change mitigation.

Why do different wheat cultivars respond differently to climate change?

Global climate change is putting pressure on our wheat crops with rising temperatures, droughts and higher concentrations of CO2, but the different wheat cultivars respond very differently. Researchers from Aarhus University, among others, have come closer to understanding why this is the case - and thereby a step closer to climate-proofing the…

When there is a surplus of electricity from wind or solar, the energy storage is charged. This is done by a system of compressors and turbines pumping heat energy from one or more storage tanks filled with cool stones to a corresponding number of storage tanks filled with hot stones. This makes the stones in the cold tanks very cold, while it gets very hot in the hot tanks, up to 600 degrees. Illustration: Claus Rye, Stiesdal Storage Technologies.

Denmark's largest battery - one step closer to storing green power in stones

The concept of storing renewable energy in stones has come one step closer to realisation with the construction of the GridScale demonstration plant. The plant will be the largest electricity storage facility in Denmark, with a capacity of 10 MWh. The project is being funded by the Energy Technology Development and Demonstration Program (EUDP)…

Researchers evaluate the competition for food plants between honey bees and other bees in Denmark

Overlap of food and the Danish list of threatened species (red list) can help to guide action plans and management of bees in nature areas in Denmark, new research from leading European bee researchers from Aarhus University, among others, shows.

Green demonstration plant ravaged by fire

A building at AU Foulum, which among other things houses a demonstration plant for biorefining, was ravaged by fire on Tuesday night. Despite damage to the building, the researchers expect that the experimental activities will be able to resume within two weeks.

Lucerne and chicory have the potential to loosen compacted subsoil

Using a medical CT scanner in a laboratory experiment, researchers have assessed the ability of five crops to loosen heavily compacted soil caused by heavy machinery. Long-term cultivation of lucerne and chicory show great potential for mitigating subsoil compaction.
