It is good to know that 70% of electricity is lost between generation and end users. I shared before that rooftop solar costs twice as much as what it costs a solar farm, but if it costs twice as much, but actually provides 5/3rds the value, that sounds like a good benefit. |
Not 70% of electricity, around 70% of the fuels original energy, unless it's a natural gas burned in a
combined cycle plant.
Or a large 2 stroke diesel engine, when I say large I mean like 50,000hp and bigger.
The most efficient a single rankine cycle plant can be is around 42% on paper. In real life its like it's more like 35 to 38%.
A Rankine cycle running off the heat rejection of a Brayton cycle can achieve combined system efficiency of around 70%.
Nuclear pressurized water reactors tend to run a little less efficient to achieve a wider margin of safety, mainly due to the limitations of a 2 pass water system. Can anyone blame them?
