Hydrogen is often seen as a key element in the global energy transition, offering a cleaner alternative to fossil fuels—in particular for difficult-to-decarbonize sectors such as heavy-duty transportation and steel and cement manufacturing. But turning hydrogen into a globally traded commodity requires more than just production.

Climate change: Why do some climate models predict it will be much hotter than others?

As Helene made landfall in Florida’s Big Bend region, birds were stuck inside its eye, where the wind is calmer. The tropical storm could disrupt fall bird migration.

In a recent study published in Engineering, researchers from Kyoto University have unveiled a novel method for the efficient separation and recycling of rare-earth elements (REEs) from end-of-life magnets. This innovative process, known as the selective extraction–evaporation–electrolysis (SEEE) process, promises to significantly advance recycling technology and support global efforts towards carbon neutrality.

A team of scientists has developed a novel digital encoding and data storage system based on a combination of microcapsules containing different luminescent dyes and phase change materials. This work represents an important step forward in the field and could be key to the development of complex encryption systems for different areas such as cybersecurity or anti-counterfeiting.

Transcranial focused ultrasound, a non-invasive technique to stimulate specific areas of the brain using high-frequency sound waves, could be a promising treatment strategy for many neurological disorders. Most notably, it could help to treat drug-resistant epilepsy and other conditions associated with recurrent tremors.

A recent study published in Engineering has unveiled a novel analysis-oriented stress–strain model that promises to improve the way engineers understand and design with ultra-high-performance concrete (UHPC) confined by fiber-reinforced polymers (FRP). This advancement in concrete research, led by S.S. Zhang, J.J. Wang, Guan Lin, and X.F. Nie, provides a deeper insight into the compressive behavior of FRP-confined UHPC, addressing a critical gap in current structural engineering models.

It is widely recognized that finance is one of the critical enablers of accelerating climate action. However, renewable energy deployment (particularly in developing countries) requires more financing than fossil fuel-based alternatives due to a combination of factors, such as higher upfront investment costs.

Hydrogen is often seen as the fuel of the future on account of its zero-emission and high gravimetric energy density, meaning it stores more energy per unit of mass compared to gasoline. Its low volumetric density, however, means it takes up a large amount of space, posing challenges for efficient storage and transport.

A team of AI researchers at Universitat Politècnica de València, in Spain, has found that as popular LLMs (Large Language Models) grow larger and more sophisticated, they become less likely to admit to a user that they do not know an answer.

The number of tidal power and other offshore renewable energy installations is set to grow significantly around the UK coastline over the coming decades.

Unmanned aerial vehicles (UAVs), commonly known as drones, have proved to be highly effective systems for monitoring and exploring environments. These autonomous flying robots could also be used to create detailed maps and three-dimensional (3D) visualizations of real-world environments.

Stanford-led research reveals how water systems, from desalination plants to wastewater treatment facilities, could help make renewable energy more affordable and dependable. The study, published Sept. 27 in Nature Water, presents a framework to measure how water systems can adjust their energy use to help balance power grid supply and demand.

Flaps perform essential jobs. From pumping hearts to revving engines, flaps help fluid flow in one direction. Without them, keeping liquids going in the right direction is challenging to do.

A research team has developed a new fluorine-free binder and electrolyte designed to advance eco-friendly, high-performance battery technology. Their findings were recently published in the Chemical Engineering Journal.

Dramatically expanding climate-action policies across all levels of government, sectors of society and the economy could slash U.S. greenhouse gas emissions by 65% by 2035 compared to 2005 levels, according to a new report from the University of Maryland's Center for Global Sustainability (CGS).

Washington State University scientists successfully tested a new way to produce sustainable jet fuel from lignin-based agricultural waste. Published in the journal Fuel Processing Technology, the team's research demonstrated a continuous process that directly converts lignin polymers, one of the chief components of plant cells, into a form of jet fuel that could help improve performance of sustainably produced aviation fuels.

Cryptocurrencies have been condemned over their environmental record at a time when traditional investments have been rapidly moving towards greener environmental, social and governance (ESG) values. So how long will it be until crypto earns its green credentials?

Thanks to recent advances in artificial intelligence (AI), civil engineers can inspect large-scale infrastructure more efficiently and cost-effectively, while also monitoring the progression of damage severity over time.

To avoid being caught, murderers often attempt to hide bodies using various methods. This can include shallow or deep burials, submersion in water, encasing in concrete or even disposing of remains in rubbish bins and suitcases.
