Batteries will only become highly competitive within the aviation field when an inventor or a group of researchers can produce a lightweight version.
Until that time (which I cannot see happening within the next 20 years - but I've been wrong, once), then the sheer, unavoidable heavy weight penalty of batteries will mean that they will be limited to equipment and processes that are strictly ground-based. |
Battery-powered multi-copters (aka "drones") don't seem to be "strictly ground based"...

The 787 batteries were in normal operation when they caught fire. The Samsung batteries were in normal operation when they caught fire. That they did so due to design flaws merely reiterates my point that they catch fire in normal operation unless you're very careful with the design. We don't understand the disastrous failure modes of yet-to-be-invented-mega-battery. The failure modes of current lithium cells ARE understood, and were fully understood long before they were certified in aircraft installations. If we develop another electrical storage technology then its failure modes will be subjected to extensive testing long before it gets onto any airborne platform. Everything we bolt onto, carry inside or employ as part of the use of aeroplanes is subject to the same detailed investigation and clearance process before use, so a blanket "we must never use mega-batteries in aeroplanes because it will offend the ancient gods" attitude seems a little excessive IMHO.

The OP mentions London - Paris..
There already is an electric transport going from London to Paris, its called the Eurostar.... |
