UK startup Orbex has showed off its Prime Rocket's second stage. Inside the engineering prototype's shell is the "world's largest" 3D printed rocket engine, which is also designed to run on bio-propane, a renewable fuel source.
Etihad Airways has become the world's first airline to fly a commercial flight using locally produced sustainable fuel derived from plants grown in saltwater.
Spain’s state-owned chain of grand hotels often housed in ancient castles and monasteries, has announced that all 97 of its establishments will use only electricity from renewable sources from the start of the new year.
Cruise liners are a surprisingly large source of greenhouse gases and pollution, but Norwegian cruise operator Hurtigruten says it's on its way to carbon neutrality – and all thanks to dead fish.
Norway is taking action to require the use of renewable aviation fuel. It will require aviation fuel to contain at least 0.5 percent advanced biofuel starting in 2020.
Sir Richard Branson has welcomed the first commercial flight powered partly by a new form of biofuel converted from alcohol.
A research team, led by Sandia National Laboratories, has discovered a way to power research ships with zero-emission hydrogen. The hydrogen-powered engine could effectively replace commonly used diesel.
The Wendelstein 7-X stellarator is close to hitting sustainable nuclear fusion (generating more energy than is initially required to start the reaction).
Portugal's electricity consumption was met fully by renewable energy for a 70-hour period beginning on March 9 and for a 69-hour period beginning on March 12.
Australia's biofuel industry has the potential to add more than 8000 jobs and $1 billion a year in revenue to the economy despite being neglected for more than a decade.
Nuclear fusion promises to be a clean source of energy, but it is expensive, technologically complex, and far from being deployed on a commercial scale.
The technology could lead to cheaper hydrogen cars in the future.
Qantas recently announced it will operate the world’s first bio-fuel flight between the United States and Australia. The Los Angeles to Melbourne flight will take place early next year.
It appears that Costa Rica just bested its 2015 achievement, having run for 300 days on a mixture of hydro, wind, geothermal, biomass, and solar energy.
The oil-rich Salicornia being grown as part of the pilot project is being used to produce aviation biofuel. It is an important milestone in the life of the project — which aims to begin producing “sustainable” jet fuel for the local aviation industry.
