Turning Hydrogen into a Liquid Vehicle Fuel
It is widely accepted that hydrogen will be the fuel of the future. Today, most hydrogen is derived from methane, but future hydrogen might generate through solar and wind power to electrolyze water. Vehicles powered by hydrogen are not only carbon dioxide-free but only emit a thin trail of water as they move. Unlike electric cars, it is possible to refuel these cars in less than a minute.
Hydrogen must also be compressed for storage and shipping purposes because it is an extremely light molecule. As of right now, it is impossible to convert the existing fossil fuel infrastructure that transports and stores fossil fuels into hydrogen infrastructure because it would be highly expensive.
Digesting Fluorocarbons Instead of Destroying Them
A fluorocarbon is a chemical compound that is tough, unreactive, and corrosion-resistant. Chemical stability is an essential ingredient since they are responsible for making many products we use daily, including refrigerants, foam blowing agents, lubricants, sealants, and nonstick coatings. They do not break down once they have been installed, and they do not react to anything that comes into contact with them. The fluorocarbons are often required to be destroyed during the breakdown of air conditioners and other products in which they are used. It has been shown that transporting fluorocarbons isn't difficult at all. The most commonly encountered obstacle in the refrigerant reclamation supply chain is contamination. This can occur when two refrigerants are accidentally mixed together, but this doesn't cause an issue.
A Greener Route to Ethylene
One of the first targets for chemical companies is their most notorious source of carbon dioxide: steam crackers. Natural gas and other hydrocarbons are burned in steam cracker furnaces to reach the temperatures of 900°C that break the carbon-hydrogen and carbon-carbon bonds in ethane, naphtha, and other feedstocks.
