Range extender for hybrid vessels by Torqeedo


The German company, specialised in electric motors for vessels, intends to launch a 25 kW range extender for its system Deep Blue. In order to do so, Torqeedo teams up with Dutch company WhisperPower.

The generator is supposed to consumes just 295 g of fuel per kWh of electricity produced and – consistent with ‘WhisperPower’ – is said to be much less noisy than comparable equivalents.

Integrated into Torqeedo’s Deep Blue hybrid system, the range extender is part of an advanced feature set on board. The system harvests energy from solar panels and hydrogeneration to charge the boat’s batteries, manufactured by BMW i. In July 2017, both companies started their cooperation, enabling Torqeedo to use the i3’s power pack for energy storage in its series Deep Blue and to make use of the i8’s battery as well.

Not long ago, Torqeedo has been acquired by German engine manufacturer Deutz. The company considers Torqeedo a catalyst for its “e-Deutz strategy” and plans to soon serial produce innovative components. Each component of the first series can be scaled to meet customers’ demand.

25g fuel / kWh electricity produced ????? 1kg of diesel contains 11.6 kWh 25g of diesel contains 0.29 kWh A 100% conversion of fuel to electricity in the best case with no loss (impossible - generators itself are not 100% efficient) 0.29 kWh fuel = 0.29 kWh electricity You claim in this article 0.29 kWh of fuel producing 1kWh electricity !! 345% efficiency!!! You just solved the worlds energy problem! Go range extender forget soloar!!!

Thank you for correcting the error in the article. Nevertheless, 3.422kWh of fuel to produce 1kWh of electricity is not an accomplishment worth to be mentioned. That is representing a fuel efficiency of 29.22%. Gas engine generators from major manufacturers reach 49% electrical efficiency. Fuel cells convert meathan at 65% efficiency (noiseless) to electricity. I think, we can all agree that increased fuel efficiency reduces emissions most effectively. I personally can’t understand why we are still investing in technologies which don’t have an advantage in improving fuel efficiency.
