Any chance this technology can make its way into marine propulsion in the future?
sCO2 turbines have a (PWR) power to weight ratio comparable to jet engines / gas turbines.
Imagine a nuclear powered warship running off a molten salt reactor coupled with sCO2 turbines.....or maybe that's overkill?

CS21 being used in new methanol power ship that will be used along Yangtze River.


On a side note, is no one excited they developed a medium speed 20 cylinder diesel engine that can do 9 MW? This is significantly more powerful than the normal 16 cylinder 7 MW engines.
Where's the post about 9 MW 20 cylinder diesel? I don't see it.

Also, it's only exciting if it's getting into naval vessels (like a new frigate, for example). Otherwise it's cool, but nothing to be excited about.

Is it me or I'm tripping that Wartsila got an engine in the same class with fuel efficiency of like 169g/kWh on diesel with much per higher cylinder power. Surely this isn't the best China has right.
Can you post a link?

this CSSC engine is better than MTU competitor

I am also a little puzzled by the question.

185g/kwh is equivalent to 5.4kwh/kg.

each kg of diesel contains 11.8 kWh of energy.

so this engine is 45.8% efficient. Just how efficient do you people think diesel generators are?

It's the Wartsila 31, medium speed diesel that also supports dual fuel. Power range from 4.6MW for a 8 cylinder to 10.4MW for 16 cylinder which is similar as well.

Official brochure claims 169.4g/kWh for diesel only version of the engine and 176.5g/kWh for the dual fuel version.wartsila.jpg
