Both India and Australia think it is worth a shot. The CSIRO may already have a solution.

"Hydrogen itself isn’t actually a fuel — it’s an energy carrier. Hydrogen is regarded as the energy source of the future.

Hydrogen is produced by splitting water molecules into hydrogen and oxygen by the electricity-driven process electrolysis. The hydrogen is then condensed under pressure and at very low temperatures into a liquid, which can be used in much the same way as petrol and diesel, or it can be used in fuel cells to generate electricity. This hydrogen and oxygen produced thus are stored to be used by a fuel cell to produce electricity when no sunlight is available. It can be converted into transportable forms as “Liquid Hydrogen Fuel” for export.

The future of hydrogen is bright. Since it doesn’t emit carbon dioxide when it’s burned, hydrogen is potentially the ultimate source of clean energy. Australia is set to be the first to do the latter after signing a deal with Japan to ship liquid hydrogen in bulk from Victoria. Australia is opening up a whole new energy market by using hydrogen to export its solar power."
