  • Answer: First of all, I seriously doubt that a car could run on methane. Methane is a gas.

    Example: Methane is in our farts.

    But if I AM wrong, and there is a way to use methane to power our cars, they probably found some way to have it combust and go through the engine, powering it. That is probably how.
  • Answer: Methane is not toxic, yet it is extremely flammable and may form explosive mixtures with air. Methane is violently reactive with oxidizers, halogens, and some halogen-containing compounds. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia may result if the oxygen concentration is reduced to below about 16% by displacement, as most people can tolerate a reduction from 21% to 16% without ill effects. The concentration of methane at which asphyxiation risk becomes significant is much higher than the 5-15% concentration in a flammable or explosive mixture. Methane off-gas can penetrate the interiors of buildings near landfills and expose occupants to significant levels of methane. .
  • Answer: yes

    Methane is non-toxic, but it it extremely flammable and can be explosive in the right concentration in air. If methane displaces enough of the air in a room, it can cause death by asphyxia.
  • Answer: Yes, but not pure methane.
  • Answer: Methane Methane is the simplest hydrocarbon with the molecular formula CH4. Methane could be produced from electricity of renewable energies. Methane can be stored more easily than hydrogen and the transportation, storage and combustion infrastructure are mature (pipelines, gasometers, power plants).As hydrogen and oxygen are produced in the electrolysis of water, 2H2O → 2H2 + O2hydrogen would then be reacted with carbon dioxide in Sabatier process, producing methane and water. CO2 + 4H2 → CH4 + 2H2OMethane would be stored and used to produce electricity later. Produced water would be recycled back to the electrolysis stage, reducing the need for new pure water. In the electrolysis stage oxygen would also be stored for methane combustion in a pure oxygen environment in an adjacent power plant, eliminating e.g. nitrogen oxides. In the combustion of methane, carbon dioxide and water are produced. CH4 + 2O2 → CO2 + 2H2OProduced carbon dioxide would be recycled back to boost the Sabatier process and water would be recycled back to the electrolysis stage. The carbon dioxide produced by methane combustion would be turned back to methane, thus producing no greenhouse gases. Methane production, storage and adjacent combustion would recycle all the reaction products, creating a cycle.Source
