X-post from reddit as it might get an answer here... http://m.imgur.com/pgskG9q?r http://m.imgur.com/pgskG9q?r This LNG ship got me wondering about a battery equivalent, charged up in a desert solar farm and shipped to a major city. I get 16 Powerpacks per 40ft container 5100 containers per Panamax ship =81600 powerpacks per ship At 95kWh per pack = 7752MWh per ship ( based on powerpack v1) So is that like two Hinckley C nuclear reactors worth of energy? How long would that last before having to go back for recharging? How long would it take to charge from a massive solar farm etc etc. so many questions but basically, is it remotely viable?

It's not "two Hinckley C nuclear reactors worth of energy" unless you confuse MW and MWh. 7752MWh per ship = two hours of Hinckley C.

Fully Charged interviewed the CEO of SunAmp recently: https://www.youtube.com/watch?v=9upXeTMHUqE https://www.youtube.com/watch?v=9upXeTMHUqE One of their new projects is to ship heat, stored in phase-change material, from a generation plant to central Bristol on a barge full of SunAmp cells. So it's a similar concept, shipping heat batteries instead of Powerpacks.

Lithium Ion batteries lose charge over time, so during transport they would discharge. Lithium Ion batteries can handle a relatively small number of recharge cycles (when compared with the number that a metal cylinder/sphere can handle when just filling it up with LNG)

Another way to approach the question is to compare the energy density of LNG to Lithium-ion batteries: https://en.wikipedia.org/wiki/Energy_density https://en.wikipedia.org/wiki/Energy_density You'd need about 10-20x more shipments of the same volume or 50-100x more shipments of the same weight to transport the same quantity of energy.
