In recent years, more than 60 countries have developed strategies to stimulate the market ramp-up of hydrogen, particularly in the industrial sector. However, in 2023, less than ten percent of the originally announced green hydrogen production was realised, shows a new study published in the journal ‘Nature Energy’. The main reason: hydrogen remains an expensive…
The biobattery that needs to be fed. A battery that needs feeding instead of charging? This is exactly what Empa researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors for agriculture or research in remote regions. Once the work is done, it digests itself from the inside….
Researchers find a potential explanation for the unusually sudden temperature rise in 2023: reduced low-level cloud cover limits Earth’s ability to reflect solar radiation. Rising sea levels, melting glaciers, heatwaves at sea – 2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees above the preindustrial level,…
Every time generative artificial intelligence drafts an e-mail or conjures up an image, the planet pays for it. Making two images can consume as much energy as charging a smartphone; a single exchange with ChatGPT can heat up a server so much that it requires a bottle’s worth of water to cool. At scale, these…
As the world races to meet net-zero targets, emissions from all industrial sectors must be reduced more urgently than ever. Agriculture is an important area of focus as it contributes up to 22% of global greenhouse gas emissions – almost as much as the energy sector. One approach to decarbonising the agricultural sector is agrivoltaics….
Researchers from Uppsala University in Sweden participate in the exploration of a geothermal field near Molyvos, on the eastern Aegean island of Lesvos, in a photo released Saturday. The investigations were initiated by the Laboratory of Hydrocarbon Exploitation and Applied Geophysics at the National Technical University of Athens’ School of Mining and Metallurgical Engineering, aiming…
The Hellenic Electricity Distribution Network Operator (HEDNO) has launched another significant green transition project aimed at making the Greek island of Ai Stratis energy self-sufficient through the exclusive use of renewable energy sources. The pilot project, titled “Ai Stratis Green Island”, is designed to meet all electricity and heating needs of the island’s residents by…
Exported gas emits far more greenhouse gas emissions than coal, despite fossil-fuel industry claims it is a cleaner alternative, according to a major new research paper that challenges the controversial yet rapid expansion of gas exports from the US to Europe and Asia. Coal is the dirtiest of fossil fuels when combusted for energy, with…
Floating offshore wind is a promising renewable energy source for several Mediterranean Countries. The exploitation of this resource will contribute to reducing carbon dependence and support the clean energy transition towards a climate neutral Europe. This work presents a novel methodology for estimating spatially-resolved Levelised Cost of Energy and offshore wind energy potential to provide…
This article aims to review the existing literature on the impact of climate change on Greece’s primary sector, focusing on sustainable management. Climate change has already caused and will persistently cause significant adverse impacts in various sectors due to environmental degradation, resource depletion, and extreme weather events. These impacts are evident in the natural environment,…
