Transcriber: Leslie Gauthier Reviewer: Camille Martínez If you're in charge of a major metropolitan city, it's almost a must these days to be sustainable. Us city dwellers pride ourselves on living in places that are taking action on climate change and achieving net zero. But what if you're Don Iveson? You're the mayor of oil and gas town Edmonton,...

Key Insights

• 🌍 Mayor of Edmonton and other cities face the challenge of reducing greenhouse gas emissions while maintaining economic and social functions tied to industries like oil, gas, and steel.
• 🌱 Carbon capture and storage (CCS) offers a potential solution by capturing CO2 emissions before they are emitted into the atmosphere and burying them underground.
• 🌎 Currently, there are very few operational CCS facilities worldwide, capturing less than 0.1% of global greenhouse gas emissions.
• 💰 To achieve the necessary increase in carbon capture capacity, an estimated $110 billion per year for the next 20 years is required, which can be achieved through cost-sharing networks.
• 📊 By optimizing the distances between emission sources and sinks, carbon capture and storage costs can be reduced by up to a third.
• 🌐 Assessment of areas for CO2 networks should consider proximity to storage, clusters of high CO2 sources, and the ability to scale up the network quickly.
• ⚙️ Networks like these have the potential to enable future innovation in using captured CO2 for various applications, such as building materials.
• 🌍 Collaboration and sharing of infrastructure between neighboring emitters is crucial for the success of carbon capture and storage networks.

Questions & Answers

Q: What is carbon capture and storage?

Carbon capture and storage is the process of capturing carbon dioxide (CO2) emissions from burning fossil fuels and storing them underground, effectively reducing the amount of CO2 released into the atmosphere.

Q: Why is carbon capture and storage important for cities like Edmonton, Scunthorpe, and Granite Falls?

Cities like Edmonton, Scunthorpe, and Granite Falls, which have significant emissions linked to local employment in industries such as oil and gas, steel, and ethanol production, can benefit from carbon capture and storage. By capturing and storing CO2 emissions, these cities can address both pollution and employment concerns while working towards combating climate change.

Q: How much CO2 needs to be captured per year by 2040 to stay at or below two degrees Celsius warming?

According to the International Energy Agency, between four and seven billion metric tons (gigatons) of CO2 need to be captured per year by 2040 to stay at or below two degrees Celsius warming. This represents a significant increase from the current carbon capture capacity, which captures about 14 million tons of CO2 equivalent per year.

Q: What is the estimated cost to build out the required carbon capture and storage infrastructure to meet the IEA forecast?

It is estimated that at least $110 billion per year for the next 20 years is needed to build out the required carbon capture and storage infrastructure to meet the International Energy Agency's forecast. This significant cost can be reduced through the sharing of infrastructure and the creation of CO2 networks among neighboring emitters.

Q: What benefits can CO2 networks offer in terms of reducing capture and storage cost?

CO2 networks can reduce the capture and storage cost for many emitters by up to a third, bringing the cost down to below $100 per ton of CO2 captured based on current technology costs. This reduction in cost brings it closer to the range of carbon taxes and market mechanisms that governments in Western economies are considering or implementing.

Q: What are some examples of cities that have the potential for CO2 networks?

Edmonton, Scunthorpe, and Granite Falls are examples of cities with the potential for CO2 networks. Edmonton has suitable underground rock layers and a combination of high- and low-concentration CO2 streams that can scale up to low-cost carbon networks. Scunthorpe, with its proximity to the North Sea, and Granite Falls, with its concentration of ethanol production facilities, also show similar potential for CO2 networks.

Q: How can CO2 networks enable future innovation and a more sustainable future?

CO2 networks have the potential to enable future innovation by using captured CO2 in chemical processes to create building materials instead of burying it underground. This utilization of CO2 can lead to more sustainable practices and contribute to a better future. However, creating a favorable regulatory environment and addressing political and geographical barriers are critical for the success of CO2 networks.

Summary & Key Takeaways

• Major cities around the world are striving to be sustainable and combat climate change, even those in industries tied to greenhouse gas emissions.

• Carbon capture and storage is a potential solution for reducing emissions and preserving local employment in these areas.

• Building CO2 networks, where emissions are captured and stored underground, can reduce costs and help scale up carbon capture infrastructure.
