(short for synthetic jet fuel) is produced from CO2captured from the air (i.e., DAC with CO2utilization, or DACCU) and hydrogen synthesized through water electrolysis, with the remaining impacts offset by DACCS (Fig.1b). Following the EC-proposed ReFuelEU targets for sustainable aviation ...
(see below). It’s actually a silicon wafer impregnated with catalysts. But it can certainly make like a leaf. Pop it into water in the sunshine and bubbles of oxygen and hydrogen begin to form. That hydrogen is the key. It is a fuel that can be transferred into pressurised sto...
reality. For example, just like refining aluminum, desalinating seawater is intrinsically energy intensive. But in a world with cheap, clean electricity, residents of coastal cities could get a reliable supply of drinking water from oceanside water treatment plants instead of contested freshwater ...
