Solving for Zero: Dr. Grace Andrews of Project Vesta

TL;DR

Project Vesta is using olivine sand to harness the natural process of chemical weathering in order to transfer carbon dioxide from the atmosphere into the water to combat climate change.

Transcript

I will never know if we met our goal of limiting warming to two degrees by 2100. I will never know if my life's work paid off but my children will be here in 2100. And my children will know. (uplifting music) We are developing a negative emission technology called coastal carbon capture, which is called chemical weathering. A natural process that... Read More

Key Insights

Questions & Answers

Q: What is coastal carbon capture and how does it work?

Coastal carbon capture is a negative emission technology that utilizes the natural process of chemical weathering. Olivine sand, when it reacts with carbon dioxide and water, dissolves, transferring carbon dioxide from the atmosphere into the water.

Q: What is the role of olivine sand in Project Vesta's approach?

Olivine sand plays a crucial role in Project Vesta's approach as it undergoes a chemical reaction with carbon dioxide and water, allowing for the transfer of carbon dioxide from the atmosphere into the water, ultimately reducing its concentration in the air.

Q: What is the ultimate goal of Project Vesta?

The ultimate goal of Project Vesta is to remove a trillion tons of carbon dioxide from the atmosphere. This ambitious target reflects the scale of the climate change problem the world is facing and the need for significant carbon dioxide removal efforts.

Q: How does Project Vesta plan to implement its approach?

Project Vesta plans to apply olivine sand to beaches and let the natural processes of wave action and weathering take their course. This passive method allows for the gradual transfer of carbon dioxide from the atmosphere to the water over time.

Q: What inspired the founder of Project Vesta to pursue this work?

The founder of Project Vesta has always been fascinated by the power of the planet and wanted to be a part of finding solutions to combat climate change. The desire to create a better world for future generations, including their own children, was a driving force behind their work.

Summary & Key Takeaways

• Project Vesta is developing a negative emission technology called coastal carbon capture using olivine sand, which dissolves when it comes into contact with carbon dioxide and water.

• By applying this sand to beaches, Project Vesta aims to harness the natural process of chemical weathering to remove carbon dioxide from the atmosphere.

• The long term goal of Project Vesta is to remove a trillion tons of carbon dioxide from the atmosphere to combat climate change.
