Rolls-Royce and easyJet have confirmed the world’s first operation of hydrogen-powered aircraft engines. The ground test was conducted on an initial concept demonstrator using green hydrogen generated by electrolysis with wind and tidal energy.

This is a significant milestone in demonstrating that hydrogen can be a carbon-free aviation fuel in the future, according to the companies.

Rolls-Royce and easyJet’s decarbonization efforts are also underway. Both companies are planning to conduct long-term flight tests, in addition to the second set of tests they are currently planning.

“We started looking at what could power future aircraft five years ago, and we examined battery technology because we thought it was viable for commercial aircraft. We concluded that hydrogen would not be viable for our large aircraft due to the disruption it would cause,” David Morgan, easyJet’s chief operating officer, told BBC News.

At the end of September, easyJet published its plan to reduce its carbon emissions by 2050.

The carbon emission will come through fleet renewal, operational efficiency, modernization of airspace, SAF, and carbon removal technology.

According to the airline’s calculations, it will be possible to reduce its carbon emissions per passenger, per kilometer, by 78% by 2050, compared to 2019. The remainder will be offset by pollution reduction.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

Rice in space becomes a scientific bet for China to understand how microgravity can alter the genetics of the most important grain for Asian food security and reveal if future generations of the plant can be born, grow, and maintain their biological identity away from Earth.

How much would a Toyota Hilux cost without tax in Brazil? A diesel pickup truck priced at R$ 250,000 could drop to around R$ 127,000, showing why pickup trucks have become a luxury product in the country.

Windows without a prison-like appearance gain momentum in 2026 and promise to completely transform residential facades with more natural lighting, discreet security, increased property value, and a modern look without the burden of the old iron bars that dominated Brazilian homes for decades.

The largest precious metals mine under construction in the world is situated on a layer of ore 25 times thicker than common mines in South Africa, and has just connected a third shaft that will quintuple the extraction of platinum, palladium, and gold.
