Regen Nautic has developed a serial hybrid marine propulsion system that significantly reduces fossil fuel usage and carbon pollution. The system uses permanent magnet brushless electric motors that can convert up to 95% of available energy with no emissions except a small amount of heat. Battery banks store power for propulsion and other loads, and are recharged intermittently and efficiently by variable speed generators or shore power. This limits generator run time to only when needed, reducing emissions and energy loss. The hybrid system allows vessels to operate emission-free in harbors and while docked. Regen addresses the power needs of larger vessels by combining multiple smaller electric motors.

2. State-of-the-art serial hybrid system, permanent magnet brushless
electric motors can convert up to 95% of the available energy, with
no pollution except a small 5% released as heat. The power needed
for propulsion and other loads associated with the operation of a
vessel are provided by energy stored in high efficiency battery
banks. These banks are then recharged by high efficiency variable
speed DC generators, by shore power or any other energy source. At
sea, the generator that recharges the battery bank is only needed
intermittently, and it is programmed to work only in its most
efficient range, reducing emissions and loss of energy. Regen Nautic
has created high-powered serial hybrid marine propulsion that
dramatically reduce the use of fossil fuel, and also reduce carbon
pollution. Most importantly, there is no carbon footprint in harbours
or while docking in electric-mode.

3. Power Availability The automotive industry rarely uses
engines larger than 400 HP (large trucks). In a sizable portion
of the marine sector, this power is just not sufficient. But one of
ReGen’s other innovations was to double-up (sometime triple
or quadruple) the use of smaller motors to provide the required
power, while keeping the cost, weight and installation issues at
their minimum.
Regen’s Hybrid Square propulsion on a twin-engine vessel
consists of a mixed series electric and parallel electric
configuration, where batteries are intermittently and efficiently
recharged with a common rail DC generator.

Regen automates the optimization of energy use that includes
electric motors, power generation, energy storage, and house
loads and provide the HV switching box that together with the
automation programming ensures safe operation and provides
a seamless transition between multiple power states while at
sea or at port.
These powerful hybrid
propulsion systems are
appropriate for multiple
markets (trawlers, jet-drives,
law enforce boats, military),
multiple industries (pleasure
craft, commercial fisheries,
harbor pilots) and different
geographies.
