Swedish researchers at Chalmers University of Technology and the University of Gothenburg have developed an AI method that improves the identification of toxic chemicals – based solely on knowledge of the molecular structure. The method can contribute to better control and understanding of the ever-growing number of chemicals used in society, and can also help reduce the amount of animal tests. ...more |

Effective decarbonization of German industry – and with it, the achievement of the climate targets with a secure energy supply at the same time – is unthinkable without the expansion of hydrogen technologies. Since they are a carbon-free energy source, they do not release any emissions during combustion. Hydrogen is also suitable as a storage medium to compensate for fluctuations in renewable energy production, since it can be produced via electrolysis using any power source. As part of the "Electrolysis Made in Baden-Württemberg" project, which was completed in 2023, the Baden-Württemberg Center for Solar Energy and Hydrogen Research (ZSW) has now strengthened the region as a hydrogen location for the long term. With the participation of 40 companies, a scalable system demonstrator for alkaline pressure electrolysis with an output of 1 MWel was engineered. The pump specialist LEWA from Leonberg, Germany, also contributed to the success of the project: an ecoflow diaphragm metering pump with Ex motor feeds the water required for hydrogen production into the process. As of 2026, the system will continue to operate in the H2 GeNeSiS model region and feed hydrogen into the new pipeline along the Neckar River. ...more |

Switching to ammonia as a marine fuel, with the goal of decarbonisation, can instead create entirely new problems. This is shown in a study from Chalmers University of Technology in Sweden, where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia – as well as emissions of laughing gas, which is a very potent greenhouse gas. ...more |

The transition to a society without fossil fuels means that the need for batteries is increasing at a rapid pace. At the same time, the increase will mean a shortage of the metals lithium and cobalt, which are key components in the most common battery types. One option is a sodium-ion battery, where table salt and biomass from the forest industry make up the main raw materials. Now, researchers from Chalmers University of Technology, Sweden, show that these sodium-ion batteries have an equivalent climate impact as their lithium-ion counterparts – without the risk of running out of raw materials. ...more |

Floods recently wreaked havoc in Libya, damaging critical infrastructure and killing more than 6,000 people. Wildfires in Canada burned 18.5 million hectares, an area the size of Syria. September 2023 set “gobsmackingly bananas” heat records that unsettled climate scientists. ...more |

The tropical wood type ipê is popular for building exclusive wooden decks, and in North America and Europe, the demand for the material has increased sharply. Now, a study from Chalmers University of Technology, Sweden, shows that more than three-quarters of all ipê from the top producing region in Brazil could have been harvested illegally. "The study reveals where in the chain the greatest risks lie. It can be a tool to counteract illegal logging," says Caroline S.S. Franca, PhD student at Chalmers. ...more |

Sulphuric acid is the world’s most used chemical. It is an important reagent used in many industries and it is used in the manufacture of everything from paper, pharmaceuticals and cosmetics to batteries, detergents and fertilisers. It is therefore a worldwide challenge that sulphuric acid often contains one of the most toxic substances – mercury. Researchers at Chalmers University of Technology, Sweden, have now developed a method that can reduce the levels of mercury in sulphuric acid by more than 90 per cent– even from low levels. ...more |

By using a new method, precious metals can be efficiently recovered from thin-film solar cells. This is shown by new research from Chalmers University of Technology, Sweden. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells. ...more |

Antarctica's so-called "doomsday glacier" -- nicknamed because of its high risk of collapse and threat to global sea level -- has the potential to rapidly retreat in the coming years, scientists say, amplifying concerns over the extreme sea level rise that would accompany its potential demise. ...more |
