Technology Description:

Pacific Northwest National Laboratory (PNNL) is developing a model and mesocosm experiments to evaluate the effectiveness and impact of the marine carbon dioxide removal technique Ocean Alkalinity Enhancement (OAE) in three major coastal areas in the United States. Unlike current models that lack ground-truth data to accurately simulate OAE, PNNL will conduct tank-based laboratory experiments to validate new models that may improve our capability to estimate the effectiveness of OAE. If successful, the project could inform the growth of the maritime carbon capture industry and protection against regional ocean acidification by pinpointing the most effective OAE size, location, frequency, and duration.
