Dry water.

No, not ice, but, as the Telegraph explains it, a form of water that just isn’t wet:

Each particle of dry water contains a water droplet surrounded by a sandy silica coating. In fact, 95 per cent of dry water is ”wet” water.

Scientists believe dry water could be used to combat global warming by soaking up and trapping the greenhouse gas carbon dioxide.

Tests show that it is more than three times better at absorbing carbon dioxide than ordinary water.
Dry water may also prove useful for storing methane and expanding the energy source potential of the natural gas.

Also useful as a catalyst. Also useful for packaging other, volatile chemicals. Also useful for… well, we’ll see.
