Carbon Capture and Storage-Savior of Climate Change Solutions

Carbon Capture and Storage TechnologyExcessive emissions of carbon in the air at a large scale have been the concern of environmentalists for a long time now.

Living in this fast-paced world filled with rapid developments in terms of technology, the ongoing concern has now become a topic of worry and anxiety for the world leaders as the climate change side effects are now showing serious changes in the ecosystem. And all these changes eventually link themselves to the excessive carbon emissions in the unadulterated air.

Despite seeing a paradigm shift in the opinions of large organizations and industries aiming towards net-zero carbon goals in the upcoming years, along with various alternatives of vehicles and industries showing up now to keep a check on the carbon emissions, the damage done already and is still being done can’t be compensated so easily.

Then, what’s the solution? Decarbonization is the growth story of this 21st century. But the road to achieving is not full of flowerbeds. This is why the concept of Carbon Capture and Storage Technology (CCS), a set of technologies used to prevent carbon dioxide emissions from entering the air and safely storing them deep underground for storage, came into existence.

Background and Development of Carbon Capture and Storage Technology

Carbon Capture and Storage Technology gained recognition in the early 2000s as a way of capturing emissions from the dirtiest source of energy i.e., coal-based power generation. But its approach and applications are not only limited to this extent.

The perception that Carbon Capture and Storage Technology is all about delivering clean coal, and that its deployment at the global level is slower than predicted, had dampened the mood of pursuing this technology further when it was first being introduced.

But the truth lies in the fact that Carbon Capture and Storage Technology possesses wider applications than was predicted at that time. This is what led to the regrowth and popularity of this technology.

Why is Carbon Capture and Storage Technology Needed?

Carbon CaptureAs the only technology that can deliver deep emissions reductions in hard-to-abate industries like in the production of steel, fertilizer and cement, Carbon Capture and Storage Technology come up as the first choice.

Since decarbonizing these production units can’t be done by electrifying them with zero-carbon power; most of these processes either need carbon in their chemistry or require high heat input, neither of which electricity is capable of providing.

The second reason for promoting Carbon Capture and Storage Technology is to unlock the hidden potential of hydrogen with minimum carbon emissions.

Since hydrogen is an underdeveloped clean-burning gas that could replace fossil fuels in the upcoming years, CCS technology proves as the best-preferred option of producing this fuel without any carbon emission.

Having said that, Hydrogen can still be made by splitting water molecules into hydrogen and oxygen gases using a renewable energy machine, but this process is far more expensive than the previous one.

How does CCS Technology Work?

Carbon StorageCarbon Capture and Storage Technology generally involves three basic steps:

Capture: This process involves the separation of CO2 from other gases that are being produced during industrial processes like in cement and steel factories, etc.

Transport: In this step, CO2 is either compressed into a liquid form or kept as gas before it gets transported to a storage site

Storage: Finally in this last step, CO2 is injected or stored into an underground rock formation or a dedicated permanent storage site.

Perks of CCS Technology

Aside from bringing a positive environmental impact on the ecosystem, Carbon Capture and Storage Technology offers a wide variety of benefits to the industrial sector including:

CO2 as Fuel

Though the process is in development, CO2 could theoretically be used as a fuel. Since the process in existence is quite difficult and costly to make this happen, further development is required to achieve this feat as an alternative.

Concrete Enrichment

Captured CO2 can be utilized to improve the properties of concrete and thus increasing its durability.

Creating Additional Power

Pressurizing CO2 into a fluid form transfers heat more easily and therefore uses less energy, thus allowing power generation turbines to run more effectively.

Also, the CO2 injected into geothermal locations for storage purposes, helps in extracting the geothermal resource to create another source of renewable geothermal energy.

Job Creation

Another benefit that is often overlooked while talking about CCS lies in job creation since more technicians are now required to manage this growing field.

Final Thoughts

Despite possessing some shortcomings like carbon leakage, huge investments and transportation challenges, Carbon Capture and Storage Technology shows a tremendous potential to change the current flow of climate change.

In this technology-neutral playing field, CCS will slowly but surely take a central role as one of the key climate solutions of the century if developed carefully.
