For the foreseeable future, hydrocarbon fuel will be needed to power aircraft. Electric planes are viable for shorter distances and lighter payloads, but not for most journeys. What is required is a net zero method for aviation fuel production, and the image below outlines such a route incorporating the SPOCC Reactor.
Energy is required to break the carbon-oxygen bond in carbon dioxide. Reactions in the above cycle break down CO2 at 2 places.
Omnagen’s innovative self-powered CO2 converter; a device which converts carbon dioxide, methane and air into useful chemicals, without the need for external energy. This is how the device works.
Carbon dioxide is a very stable molecule, it will react with some minerals to form stable carbonates, but other reactions require energy. Photosynthesis, for example, uses energy from the sun to convert CO2 and water into glucose and oxygen.
CO2 is only a problem if it is in the earth’s atmosphere. The greenhouse effect is explained here.
Carbon Capture and Storage (CCS) involves capturing CO2 from the air, or exhaust gases, liquifying it, and then burying it. This is expensive, but it will allow fossil fuels to be used without releasing carbon dioxide into the atmosphere. More details about CCS.
