Frontier Climate's Alkalinity Sourcing Challenge: Driving Breakthroughs in Carbon Removal

The urgent need to combat climate change has brought innovative approaches to carbon removal to the forefront. A new challenge spearheaded by Frontier Climate offers an exciting opportunity for individuals and teams worldwide to contribute to this critical effort.

The "Alkalinity Sourcing Challenge" focuses on identifying highly reactive mineral deposits capable of enabling large-scale carbon dioxide removal.

With a $5,000 award for the best submissions, this initiative aims to address one of the planet's most pressing challenges.

Frontier Climate’s Vision for Carbon Removal

Frontier Climate has long been at the cutting edge of climate solutions, advancing initiatives that align with the goal of stabilizing global temperatures around 1.5°C.

The carbon removal challenge highlights the need for innovative carbon removal technologies, particularly those that can collectively achieve the scale of removing 1 teraton of CO₂ over the next century.

“This is about leveraging natural geological processes to drive carbon removal at unprecedented scales,” says Frontier Climate’s leadership team.

By focusing on alkalinity-driven methods, the organization is taking a scientific yet practical approach to tackling the climate crisis.

The Alkalinity Sourcing Challenge

The challenge calls on participants to identify geological sites containing highly reactive minerals such as brucite, portlandite, and wollastonite.

These minerals, when exposed to carbon dioxide, rapidly weather, enabling efficient CO₂ removal. Frontier Climate has set clear criteria for eligible submissions, emphasizing:

• Mineral reactivity: Proposals should focus on minerals that fully react with CO₂ in under a decade.

• High-grade deposits: Sites must contain at least 10 gigatons of reactive minerals at a grade of 30% or higher.

• Compact geography: Submissions should identify sites under 500 square kilometers with uniform geological characteristics.

By crowdsourcing ideas, the challenge aims to uncover untapped potential in mineral deposits worldwide.

“We believe the collective creativity of the scientific community can uncover new solutions to the carbon removal challenge,” adds Frontier Climate’s team.

How to Participate

Interested applicants are encouraged to submit a detailed “Site Hypothesis,” outlining their proposed site, its geologic history, and evidence supporting the presence of reactive minerals.

Submissions will be reviewed by Frontier Climate in collaboration with expert academic reviewers.

The deadline for entries is January 6, 2025, with winners announced by the end of the month.

The process is designed to be inclusive. “Whether you’re a student, geology enthusiast, or professional researcher, your ideas are welcome here,” emphasizes Frontier Climate.

Why Alkalinity Matters

Alkalinity-driven carbon removal methods harness naturally occurring minerals to accelerate CO₂ absorption.

This approach could complement existing carbon capture technologies, offering a scalable and cost-effective solution.

For example, minerals like brucite and wollastonite react with CO₂ at rates far exceeding traditional silicate materials like olivine, making them ideal candidates for rapid deployment.

However, despite their potential, detailed mapping of these deposits remains limited—underscoring the importance of initiatives like this one.

The Award and Beyond

Frontier Climate is awarding $5,000 to the top 10 submissions that meet the challenge criteria.

Beyond the monetary prize, participants will have the opportunity to stay involved in research and contribute to future developments in the field.

“We hope this challenge inspires people to think creatively about how natural resources can be harnessed to combat climate change,” says Frontier Climate’s leadership.

Winners will join a growing network of innovators working to shape the future of carbon removal.

Creating Lasting Impact

The Alkalinity Sourcing Challenge is more than just a competition—it’s a call to action for those passionate about science, sustainability, and problem-solving.

By tapping into global expertise, Frontier Climate aims to unlock new pathways for achieving large-scale carbon removal.

This initiative demonstrates the power of collaboration in addressing complex environmental challenges.

With the collective efforts of participants worldwide, the goal of removing 1 teraton of CO₂ feels a little closer to reality.
