In today's episode, hosts Anna Madlener and Wil Burns are joined by Grace Andrews from Hourglass Climate. They discuss Hourglass' work on environmental monitoring and carbon removal quantification of Ocean Alkalinity Enhancement (OAE) trials as a research non-profit.

Grace started her career in academic research, studying chemical weathering and alkalinity under glaciers and ice sheets. She later explored the relationship between rock weathering and ocean-based carbon removal, which prompted her shift to the private sector, at Vesta – a climate startup focused on coastal olivine-based alkalinity enhancement. Today, she’s the Executive Director of Hourglass Climate, where she leads a team focused on conducting transparent and open-source research on mineral-based OAE techniques.

In this episode, the Plan Sea hosts and Grace discuss how Hourglass is advancing current OAE field trials, including quantifying the efficacy, assessing the safety of projects, and expanding strategies to effectively share information and communications.
