Carbon capture: the hopes, challenges and controversies | FT Film
Financial Times・17 minutes read
Carbon capture and storage (CCS) is crucial for industries like steel and cement to achieve net zero emissions, with the oil and gas sector still debating its role and the need for significant changes. Negative emission technologies are vital due to high CO2 levels, with CCS projects capturing minimal CO2 currently, requiring a substantial increase by 2030 for net zero goals.
Insights
- Carbon capture and storage (CCS) is crucial for achieving net zero emissions in industries like steel and cement, but its role in the oil and gas sector is contentious, requiring significant system changes to be effective.
- Negative emission technologies, including direct air capture and bioenergy with CCS, are essential for reducing high CO2 levels in the atmosphere, with a substantial increase in CCS projects needed by 2030 to meet net zero goals. These technologies are seen as vital alongside hydrogen production to decarbonize effectively, emphasizing the need for a diverse mix of solutions beyond renewable energy sources like wind and solar power.

Recent questions
What is carbon capture and storage (CCS)?
Carbon capture and storage (CCS) is a technology that captures carbon dioxide emissions produced from industries like steel and cement, preventing them from entering the atmosphere. The captured CO2 is then stored underground in geological formations to reduce greenhouse gas emissions and combat climate change.
Why is negative emission technology important?
Negative emission technologies are crucial because they help reduce the high levels of carbon dioxide already present in the atmosphere. By capturing and storing CO2, these technologies play a vital role in achieving net zero emissions and combating climate change effectively.
How do oil and gas companies contribute to CCS projects?
Oil and gas companies are major investors in CCS projects due to their expertise in finding and storing CO2. They utilize captured CO2 for enhanced oil recovery, increasing oil well pressure and extracting more oil while simultaneously reducing greenhouse gas emissions.
What is carbon capture usage and storage (CCUS)?
Carbon capture usage and storage (CCUS) involves reusing captured CO2 in industries like fertilizer production, providing a sustainable way to reduce emissions. This process not only helps in combating climate change but also contributes to the circular economy by repurposing captured carbon dioxide.
Why is hydrogen considered a key molecule for future energy solutions?
Hydrogen is seen as a key molecule for future energy solutions because it can be used as a clean fuel in power generation and as a reduction agent in industries like steel production. With the rise in investment and the need for increased consumption to achieve net zero emissions, hydrogen offers a versatile and sustainable energy option for decarbonizing society effectively.

Hydrogen: Key Molecule for Future Energy
- Hydrogen is seen as a key molecule for future energy solutions, with a rise in investment and the need for increased consumption to achieve net zero emissions. It can be used as a clean fuel in power generation and as a reduction agent in the steel industry, produced as green hydrogen using clean energy or as blue hydrogen from natural gas with carbon capture.
- While green hydrogen production may not yet be scalable or cost-effective for all applications, blue hydrogen is considered a bridging fuel. However, concerns exist about continued reliance on fossil fuel companies and the need for a mix of technologies like carbon capture, green and blue hydrogen, electrification, wind, and solar to decarbonize society effectively.
