hydrides

This is overcome with the use of metals in hydrides, but then these can only be used for certain applications because they are very heavy and are thus not good for storing in cars.

The result is it must be either highly compressed, which means very expensive carbon fiber tanks (steel won't do) or cryogenically chilled to liquify it and store it in very expensive dewar tanks, where it still will boil away, or store it absorbed in metal hydrides which is the most expensive and adds considerable weight.

If this technology was implemented in a fuel cell vehicle, it would cost about $200, as opposed to using carbon nanotube tanks (which cost about $5.5 million) or metal hydrides (which cost about $30,000).

The fact that other reports of excess heat do not produce these hydrides and can evolve over days or weeks suggests the opposite condition of starvation where oscillation is delayed and slow but still occurs over time as the atomic gas slowly accumulates the velocities needed to exchange time dilation for energy.

The options are to store it at very low temperature (cryogenically), at high pressure, or chemically as hydrides.

But the most clever way to do it is with metal hydrides.

Metal hydrides are also relatively mature, but require further R&D to be competitive.
