Claiming a system-level energy density 5X higher than batteries, Amogy has rolled out “the world’s first ammonia-powered, zero-emission semi truck.” It holds about 900 kWh of energy, like the Tesla Semi, but you can refuel it in about eight minutes.

Scientists from UNSW Sydney have demonstrated a novel technique for creating tiny 3D materials that could eventually make fuel cells like hydrogen batteries cheaper and more sustainable.
In the study published in Science Advances, researchers from the School of Chemistry at UNSW Science show it’s possible to sequentially “grow” interconnected hierarchical structures in 3D at the nanoscale which have unique chemical and physical properties to support energy conversion reactions.
In chemistry, hierarchical structures are configurations of units like molecules within an organization of other units that themselves may be ordered. Similar phenomena can be seen in the natural world, like in flower petals and tree branches. But where these structures have extraordinary potential is at a level beyond the visibility of the human eye—at the nanoscale.
It’s not just information that can move from one point in the universe to another, without passing through the space in between.
Photosynthesis is the greatest natural process converting sunlight into chemical energy on a massive scale and maintaining life on Earth. There are basically two successive stages of oxygenic photosynthesis.
Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.
I remember when this was a guitar.
The Flying-V, an experimental aircraft that promises significantly greater fuel efficiency over more conventional commercial jet designs, is moving towards a larger, more detailed version since the scaled, 10-foot model took flight in 2020 in Germany.
The 315-passenger jet flies like other commercial airliners its size, according to recent tests, but is 20 percent more fuel efficient. Plus, it just looks a lot cooler.
Australia has all the key critical minerals to power the next 100 years.
An Australian-based startup, Recharge Industries Pty, is planning to build a A$300 million (US$210 million) factory that can build lithium-ion batteries that do not have materials imported from China, Bloomberg.
Though Australia is the world’s largest supplier of lithium, a vital battery metal, it currently sends most of its battery raw materials to be processed into components in China.

With the explosive growth of technology, businesses are more vulnerable than ever to malicious cyber attacks. And as cybercriminals become more sophisticated, new methods of attack are popping up left and right.
To add fuel to the fire, the average cost of a data breach increased from $3.86 million to $4.24 million in 2021. That’s costly enough to put most SMBs into the red. Not to mention the reputational damage it can cause for your brand.
Piasecki Aircraft Corp. (PIAC) and edm aerotec have signed an agreement to develop the world’s first hydrogen-powered helicopter. Based in Pennsylvania, PIAC has a long history of designing experimental aircraft for civil and military applications.
CEO John Piasecki told a recent symposium at the Vertical Flight Society that his company would be performing the world’s first human-carrying flight tests aboard edm aerotec’s CoAX-2D helicopter. The hydrogen-powered CoAX-2D would use an 80-kW HyPoint high-temperature proton-exchange membrane (HTPEM) fuel cell, according to EVTOL.news.
Each of these piles represents a critical mineral needed to make the transition from fossil fuel-based energy to renewables possible.
Guest contributor, Jane Marsh, describes the challenges the U.S. and its allies face in securing minerals used for the energy transition.

Replacing fossil fuel with hydrogen seems like an ideal solution to make transportation environmentally friendly and to provide a backup for intermittent energy sources like solar and wind. But how environmentally friendly is hydrogen really? And how sustainable is it, given that hydrogen fuel cells rely on supply of rare metals like platinum and iridium? In this video, we have collected all the relevant numbers for you.
