A Zirconium doped Copper-Zinc-Gallium Catalyst for Thermochemical CO2 Conversion to Methanol.

2. I actually prefer the symmetric ether made from methanol, dimethyl ether, which can displace diesel fuel, LPG...

...natural gas in all applications.

It is an easily liquifiable gas with a critical temperature higher than the boiling point of water, 401K, is easily removed from water, is relatively nontoxic - slightly anesthetic - and has an atmospheric half-life of 5 days, and thus, unlike methane is not a climate forcing gas and lacks any corrosive properties, although for engines, some changes to seals would be necessary.

It is also an excellent refrigerant. It's thermodynamic properties on synthesis from hydrogen and carbon dioxide is slightly exothermic.

In short, it is cleaner than any other fuel, safer than another fuel, and more sustainable than any other fuel. It's essentially a "drop in" on existing infrastructure, unlike the hydrogen that the fossil fuel green washer comes here to sell.

I'm less concerned with its properties as a motor fuel than its sustainability. DME is a wonder fuel.
