Diesel hybrids question.

[Plevier]

Have a look at http://www.hymar.org/index.html
Nigel Calder heavily involved but I haven't seen any updated reports for a while.
Some comments here too http://threesheetsnw.com/blog/2012/...engine-and-you-may-be-surprised-what-he-sees/

I know this isn't a straight answer to the OP's question but lots of background info!

I was always puzzled by the enthusiasm of some for the HYMAR project but maybe I understand it now, having read the second reference - $3M of EU cash could certainly generate some!

If it's inherently inefficient to have additional conversion steps, why do locomotives and commercial ships use diesel-electric propulsion? Clearly there must be a compelling reason?

Cal Mac have announced they are introducing diesel electric ferries on some routes - Tarbert to Portavadie is one. I did think that the batteries would be charged by shore power using 'off peak' electric overnight with the diesel generator as backup.
But on reflection its probably so they can use azipods for better maneouvrability.

The Call Mac ferries on the Bute to Wemyss Bay service are diesel-electric. A 2000 hp diesel generator drives 4 propulsion units, one in each corner.
No off-peak shore charging though! That might dim the lights in Rothesay.

The lion batteries would cost a packet as well I guess!
