Biofuel

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.

Airbus has achieved a green aviation first as an H225 made the first-ever helicopter flight with both of its Safran Makila 2 engines running on 100 percent Sustainable Aviation Fuel (SAF), which is usually derived from biomass.

As part of a broader push on part of the aviation industry to reduce its carbon footprint, Airbus has conducted the first ever flight of its giant A380 jumbo jet using 100 percent biofuel, made up of primarily cooking oil.

Synthetic fuels are not new, nor is their use in aircraft, but the normal practice is to blend them with fossil fuels. The Royal Air Force has now set a new record by completing the first ever aircraft flight powered entirely by synthetic fuel.

A team at the Georgia Institute of Technology have come up with a concept that would see bacteria shipped to Mars produce rocket fuel and liquid oxygen from atmospheric CO2 to power a spacecraft on its return journey to Earth.

The USAF is studying the feasibility of a process developed by tech company Twelve that could allow the manufacture of a carbon-neutral aviation fuel called E-Jet anywhere on Earth using only carbon dioxide from the air, water, and renewable energy.

Even with today's various sewage-treatment technologies, a great deal of municipal wastewater is still released back into waterways either partially or completely untreated. According to a new study, however, plots of willow trees could be used to clean it up – while also producing useful materials.

The brewing of beer produces great quantities of leftover grain, which often ends up being processed into cattle feed. Scientists have developed a new method of extracting the protein and fiber from that waste, however, for use by humans.

So far as feedstocks for the production of biofuels go, kelp is a highly promising one on many fronts, and a new technology promises to boost its credentials even further by maximizing its exposure to both sunlight and nutrients.

Many people take Spirulina as a dietary supplement, but researchers at the Swiss Federal Laboratories for Material Science have found a way to put the tiny spirals to work removing contaminants from water, and then make biofuels from their remains.

Sargassum seaweed is growing out of control in many regions – it washes up on beaches in huge amounts. Utilizing a new technique, that rotting organic matter could soon be converted into biofuels and other products.

Corals serve as a host to algae, which produces sugars that the corals consume. Now, scientists have 3D-printed coral that's even more algae-friendly than its natural equivalent – it could help limit coral bleaching, and provide a source of biofuel.
