CASHEW

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.m file in the src/pump_model folder. Then plot the results using the plot_results.m file in the same folder.
• To run the MATLAB model for steady state pressure and flow, run the pressureTempCalc.m file in the src/energyAndTempCalcs folder.
• To run the MATLAB economics model, run the fom_sweep.m file in the src/econ folder.
