Carbon assessment #133

Open SplitN opened 1 year ago

Hi,

I was wondering if you made a carbon assessment of the IEA-15-240-RWT ?

Best regards

Hi, I'm not sure whether I understand your question. Are you asking whether we compared a blade with GFRP spar caps vs CFRP spar caps? We are aware of the unrealistic properties of the CFRP in the IEA15. This is listed in the wiki page here https://github.com/IEAWindTask37/IEA-15-240-RWT/wiki/Frequently-Asked-Questions-(FAQ)#are-the-cfrp-properties-wrong In the new project to define the new offshore reference wind turbine, CFRP properties are different, see here https://github.com/IEAWindTask37/IEA-22-280-RWT/blob/7f6eebcb8ea2e7c4cf25748f3aba05c24ba8bd8e/windIO/IEA-22-280-RWT.yaml#L938 Best regards, Pietro

And to add to my previous reply, no, we didn't compare GFRP vs CFRP for this blade, although GFRP would bring a fairly strong mass penalty to the blade design

No I wasn't clear enough. I'm looking for the carbon footprint or a life cycle analysis of the wind turbine

This is not part of our reference turbine effort. It is really an active area of research to be able to estimate this sort of thing. My best suggestion is to do a detailed literature search. Here is one recent paper to get started.
