As the effects of climate change continue to worsen, companies like Google are investing heavily in innovative solutions to mitigate its impact. In a recent development, Google and other prominent companies have partnered with Terradot, a startup backed by Sheryl Sandberg’s venture capital firm, to remove 90,000 tons of carbon dioxide from the atmosphere using enhanced rock weathering (ERW).
The Science Behind Enhanced Rock Weathering
Enhanced rock weathering is a relatively low-tech approach that involves accelerating the natural process of rocks breaking down in response to rainfall. This reaction releases calcium and magnesium ions into the water, which then combines with carbon dioxide to form bicarbonate, effectively trapping CO2 in the ocean. By crushing up rocks and spreading them over large areas, Terradot aims to increase the surface area exposed to this reaction.
The Terradot Deal: A Multimillion-Dollar Investment
Google, along with H&M Group and Salesforce, has agreed to pay Terradot $27 million to remove 90,000 tons of carbon dioxide from the atmosphere. The deal was brokered by Frontier, a carbon removal initiative led by Stripe, Google, Shopify, and McKinsey Sustainability. Separately, Google announced its own agreement to purchase an additional 200,000 tons of carbon removal from Terradot.
The Cost-Benefit Analysis
While the exact cost of the larger deal with Google is not disclosed, estimates suggest it could add up to $60 million, assuming a similar price per ton as the Frontier agreement. However, Google expects the price to decrease over time for this larger deal.
Industry Reactions and Expert Insights
Oliver Jagoutz, a professor of geology at MIT, views this development as a significant breakthrough: "It’s a big deal. I think it should go a little out of the academic world into the industrial world. And I wish these guys all the best."
However, experts also highlight the challenges and limitations of carbon removal technologies. For instance, estimating how much CO2 is actually captured through ERW is difficult due to factors like soil degradation rates and fertilizer usage.
The Role of Carbon Removal in Mitigating Climate Change
While carbon removal is a crucial step in addressing climate change, it’s essential to understand its limitations. Experts emphasize that preventing greenhouse gas emissions remains the most effective way to slow down climate change. Carbon removal should be seen as a supplementary strategy to help counteract legacy pollution while companies transition to clean energy sources.
Terradot’s Plan: Accelerating ERW on a Large Scale
To meet its ambitious goals, Terradot plans to deploy ERW technology widely in the real world, gathering data and refining measurement tools. The company aims to assess CO2 capture rates based on soil samples over time, but acknowledges that quantifying long-term sequestration remains an open question.
Conclusion: Combating Climate Change through Collective Action
As companies like Google continue to invest in innovative climate solutions, it’s clear that addressing this global issue requires a multifaceted approach. While carbon removal technologies hold promise, their limitations and uncertainties must be acknowledged. By working together towards emissions reductions and deploying these emerging technologies, we can collectively make progress in mitigating the effects of climate change.
