Sustainable fuel, WindWings and supersonic travel

Microbes can be used to produce jet fuel through a process called fermentation. During this process, microorganisms metabolize industrial gases and convert them into ethanol, which is a key component in the production of jet fuel. In November 2023, Virgin Atlantic and Gulfstream Aerospace completed successful test flights across the Atlantic using 100% sustainable aviation fuel. This marks a significant milestone in the decarbonization of the aviation industry.

The cargo ship Pyxis Ocean has been equipped with technologically advanced WindWings sails, which are 37.5 meters high automated structures. Thanks to these sails, the ship is able to save up to 11 tons of fuel per day. The WindWings sails have been tested for six months in the Atlantic, Indian, and Pacific Oceans. In 2023, the International Maritime Organization adopted a strategy aimed at reducing the shipping industry’s carbon dioxide emissions by at least 40% by 2030.

Since the last Concorde flight in 2003, no commercial supersonic passenger jet has been built. However, private companies such as Boom, Exosonic, and Spike are attempting to change this by developing supersonic travel that is both greener and cheaper than before. The NASA space agency and Lockheed Martin have also presented the first X-59 demonstrator jet. We will be monitoring the progress of these efforts in Outriders Magazine.
