Converting CO2 directly from the air to fuel under ambient conditions is a huge challenge. Thus, there is an urgent need for CO2 conversion protocols working at room temperature and atmospheric pressure, preferentially without any external energy input.
Herein, we employ magnesium (nanoparticles and bulk), an inexpensive and the eighth-most abundant element, to convert CO2 to methane, methanol and formic acid, using water as the sole hydrogen source.
The conversion of CO2 (pure, as well as directly from the air) took place within a few minutes at 300 K and 1 bar, and no external (thermal, photo, or electric) energy was required.
Hydrogen was, however, the predominant product as the reaction of water with magnesium was favored over the reaction of CO2 and water with magnesium.
A unique cooperative action of Mg, basic magnesium carbonate, CO2, and water enabled this CO2 transformation. If any of the four components was missing, no CO2 conversion took place.

Nuclear Fuel is gaining popularity once again -
Tritium or hydrogen-3
Tritium or hydrogen-3 is a rare and radioactive isotope of hydrogen with half-life about 12 years. The nucleus of tritium contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 contains one proton and zero neutrons, and that of hydrogen-2 contains one proton and one neutron
US Department of Energy/TSTA and the Japan Atomic Energy Research Institute/Tritium Processing Laboratory. Magnesium appears to have reactive properties that are as good as uranium and possibly better, and, of course, magnesium is easier to handle and less strictly controlled. Both bench-scale and practical-scale experiments were conducted with magnesium, including tests with tritiated water. Mg bed construction techniques and operating parameters were determined. Testing showed that the Mg packed bed was very effective for recovering hydrogen isotopes from water. However, when used for this purpose, either Mg or U is irreversibly consumed and must be disposed of as tritiated waste. It follows that this processing technique would be inappropriate for a large tritiated water processing operation. However, this technique may find utility for small-scale systems

What do i see with this ?
I see a far better purpose for magnesium
storing H3 ( tritium ) could command more money
than... using mg ot stroe co2.
Secondly....
If magnesium bonds easily with 3 hydrogen ( tritium )
What is the end result formula ?
I tried looking online - to no avail.
What if a simple oxygen was introduced to this aqueous magnesium hydrogen 3 bond ?
Could an oxygen molecule attract one of the hydrogen allowing the magnesium to convert to a simple magnesium 2 hydrogen 2 bond ?
If it were possible, it would eliminate the radioactiveness.
And allow the magnesium to be used over and over.
Just ideas....
I still like my on demand hydrogen fuel cell idea -
a small unit using magnesium salts in water with a small hyodrgen tank.
Hydrogen gas production on demand.
No costly hydorgen fuel stations.
The fuel cell is leased to accommodate the control and taxes.
The fuel cells loaded with Mg and water = cylenders.
Mg could be reused over and over.
Far better than ev vehicles.
Cheers....
