Repository for CASHEW project, submitted for the DOE Power at Sea Prize.
The CASHEW (CArbon Sequestration Harnessing Energy from Waves) system uses wave power to directly pump liquid carbon dioxide into the seabed, reducing the cost of carbon sequestration. This repository contains the models used as well as many of the figures submitted to the prize.

Run our model:
- To run the Simscape model for transient pressure and flow, simply run the
runCASHEW.mfile in thesrc/simscapefolder. Then plot the results using theplot_results.mfile in thesrc/plottingfolder. Note that you must have WEC-Sim installed on your device for this simulation to work. Visit https://wec-sim.github.io/WEC-Sim/dev/user/getting_started.html#download-wec-sim to install. This model is only confirmed to work with MATLAB R2023b. - To run the MATLAB model for steady state pressure and flow, run the
pressureTempCalc.mfile in thesrc/simple_modelfolder. - To run the factor of merit model, run the
fom_sweep.mfile in thesrc/econfolder.
