In June, I had talked about the Greek geeks getting into the act when it comes to hydrogen technology by developing new storage technology along with developing new hydrogen minibuses.
Now, the Greeks have out-geeked themselves by developing hydrogen submarines that will cruise the Mediterranean Sea unnoticed by watchful eyes. Air Products Corporation will be supplying the fueling station for the fuel cell driven HDW 214 submarine that is part of the Hellenic Navy.
The Greek hydrogen submarine will be able to stay underwater for up to 3 weeks before resurfacing for fuel. This compares favorably to diesel-electric submarines that can stay submerged for only a few days before resurfacing.
Nuclear-powered submarines can stay underwater for months, but hydrogen submarines are quieter and harder to detect. Hydrogen submarines also don’t pose a problem in regard to disposal of depleted radioactive waste.
Leave it to the Greeks to dive into the hydrosphere with hydrogen submarines. With water, water everywhere one would wonder why more navies aren’t using hydrogen for fuel?
