As effective as fossil fuels may be, their impact on the planet cannot be overstated. Now researchers at Berkeley Lab have coaxed bacteria into directly producing a new biofuel with an energy density significantly higher than jet fuel.
-
Engineers have demonstrated a pilot system that produces fuels from sunlight and air. The device captures carbon dioxide and water from the air and uses solar energy to convert it into syngas, which is then converted into carbon-neutral liquid fuels.

One way scientists hope to prevent hypersonic aircraft from overheating is by having the propellant do double duty as a coolant, and newly developed 3D-printed catalysts could be the missing piece to this puzzle.
-
As part of its goal to reach net zero carbon dioxide emissions by 2050, Rolls-Royce has begun testing 100-percent Sustainable Aviation Fuel (SAF) in a small commercial business jet, which could lead to lifecycle emissions reductions of over 75 percent.
-
Engineers at the National University of Singapore have developed a new way to convert natural gas into a solid form, enabling safer and easier storage and transport. The process can be done in just 15 minutes using a low-toxicity mixture.
-
Reaction Engines and Britain's Science and Technology Facilities Council (STFC) have completed a concept study into the practicality of using ammonia as a sustainable, low-emission jet aviation fuel.
-
Researchers at the US Dept of Energy's Argonne National Laboratory have discovered a new catalyst that can convert carbon dioxide and water into ethanol with "very high energy efficiency, high selectivity for the desired final product and low cost."
-
BMW i Ventures announced today it is investing in Prometheus Fuels. The Silicon Valley startup is working on technologies for pulling CO2 out of the atmosphere and processing it into carbon-neutral gasoline.
-
Artificial leaves can convert sunlight, water and carbon dioxide into energy or even be used to produce fuels. Now, researchers from Cambridge have developed a new version that can produce synthetic gas (or syngas) without releasing carbon dioxide.
-
Hydrazine rocket fuel is highly toxic, carcinogenic and unstable, making it incredibly dangerous to work with. Scientists at McGill believe their new alternative, based on metal-organic frameworks, will lead to cleaner, safer, more controllable rockets.
-
Millions of metric tons of plastic are produced each year and in reality, very little of it is recycled. But what if there were more ways of turning this waste into something valuable, be it new plastics, hydrocarbons or different types of fuel?
-
Israeli-Australian company Electriq Global's new technology stabilizes hydrogen in a recyclable liquid that can be pumped and transported just like gasoline. That's huge, because it enables long-range electric driving with fast refueling – and it plugs right into the existing fuel logistics model.
