Wärtsilä hybrid propulsion system with methanol engine to power four SAL heavy lift vessels; wind farm installations

Green Car Congress

They will also be the first methanol capable ships to employ a variable speed main engine in a hybrid installation. The hybrid system also includes Energy Storage, a PTO/PTI generator and motor, a multidrive converter, and the Wärtsilä Energy Management System for controlling and optimiszing the hybrid operations.

Another application could provide “instant heat” to heat up the catalytic converters in vehicles. The module is compact and can be installed in about an hour. The use of the module also prevents the battery from deep cycling, extending the life of the battery. Two lithium-ion battery companies are working with us now.
