where is the pfs??????, page-192

Interesting discussion, but I think there might be some confusion around the concept of a LNG tanker that then leads to this subsequent discussion.  What drives a LNG tanker is boil off and heel (heel is leaving some gas on the vessel to insulate the LNG tanks and use some for boil off etc for the return journey).  What boil off is a very small aspect  of the LNG in the cryonogenc tanks 'heats up' and returns to gas essentially (more complicated than that but get the drift) which then is used to drive your LNG tanker to end destination and back.  Boil off is around 0.2% per day meaning for a 20 day round trip you essentially deliver 96% of the LNG cargo at end destination.  That is what self - propelled LNG carriers are - using boil off to drive the boilers/engines to get to destination.

Now line losses are an issue when transporting electricity by cable.  The further the transmission lines the greater the losses, and that is on land let alone cabling at sea. 

Battery storage works best when attached near to the power source of generation.  In other words, export vanadium to end destination where they can use it in steel or use to make their own vanadium batteries etc etc. to avoid 'electricity/transmission losses' through earlier/storage use.

I expect technology to improve over time in terms of reducing losses per km of electricity transmitted (before we talk distribution) but in the now the option available is to export the vanadium to end destination where it be used for the required end purpose.

Can a ship be run on battery technology for a 20 day round trip - developments will be required there so prefer we just focus on the now and get AVL to production than be distracted by what future technologies may hold.  AVL need to get into the market by targeting steel production requirements first, as per my comments in this post.  I would prefer VA to focus on the steel market by the way and cut the noise he keeps making about batteries in twitter land and in his presentations.  I see batteries the second stage of the development here sometime in the 2020s - steel been first in the now because that is where the vanadium shortage is given the change in the rebar standards effectively double the vanadium need in steel.

All IMO
