Organic carbon derived from terrestrial vegetation must be incorporated into the soil column and subsequently be incorporated into permafrost to be effectively stored.
In this highly complex computer brain there were more circuit elements packed into the space of a cubic centimetre than we could have stored effectively into a cubic yard and still get anywhere near the same performance.
Here the heat of compression is effectively stored in the atmosphere (or sea) and returned later on.
Solar heat (or heat from other sources) can be effectively stored between opposing seasons aquifers, underground geological strata, large specially constructed pits, and large tanks that are insulated and covered with earth.
Alternatively, it has been argued that soil erosion deposits organic carbon in places-like the bottom of the sea, for instance- where it is effectively stored.
Seeds cannot be effectively stored, and must be planted upon harvesting them from a fruiting tree.
The data must be stored effectively and efficiently with no degradation of the data over the archive's lifespan.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately.
In this case, the hydrogen is effectively stored in both the material and in the water.
Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result.
