Carbon Capture and Storage (CCS)

What is Carbon Capture and Storage (CCS)?

Carbon Capture and Storage (CCS) is a technology that captures carbon dioxide (CO₂) emissions produced by industrial processes, power generation and other activities before they enter the atmosphere, then transports and stores the carbon safely underground for long-term containment.

CCS is designed to reduce greenhouse gas emissions and help slow climate change by preventing large volumes of carbon dioxide from contributing to global warming.

As countries work towards Net Zero targets, Carbon Capture and Storage is increasingly recognised as an important tool for reducing emissions from industries that are difficult to decarbonise, while complementing renewable energy, carbon farming and other climate mitigation strategies.

How Does Carbon Capture and Storage Work?

CCS involves three main stages:

A. Carbon Capture

Carbon dioxide emissions are captured at the source, such as power stations, manufacturing facilities or bioenergy plants.

B. Carbon Transport

The captured carbon dioxide is compressed and transported via pipelines, ships or other infrastructure.

C. Carbon Storage

The CO₂ is injected deep underground into geological formations such as depleted oil and gas reservoirs or saline aquifers, where it can remain stored for thousands of years.

Types of Carbon Capture Technologies

1. Post-Combustion Capture

Carbon dioxide is removed from exhaust gases after fuel has been burned.

2. Pre-Combustion Capture

Carbon is captured before fuel combustion during industrial processing.

3. Direct Air Capture (DAC)

Technology that removes carbon dioxide directly from the atmosphere.

4. Bioenergy with Carbon Capture and Storage (BECCS)

Combines renewable bioenergy production with carbon capture to create negative emissions.

Why Carbon Capture and Storage Matters

A. Reduces Greenhouse Gas Emissions

Helps prevent large quantities of CO₂ from entering the atmosphere.

B. Supports Net Zero Targets

Provides a pathway for industries to reduce emissions where alternatives are limited.

C. Complements Renewable Energy

Works alongside renewable energy technologies to accelerate decarbonisation.

D. Supports Negative Emissions Technologies

Can remove carbon from the atmosphere when combined with bioenergy or direct air capture.

E. Decarbonises Heavy Industry

Particularly valuable for sectors such as cement, steel and chemicals.

Carbon Capture and Storage in Agriculture

While CCS is primarily associated with industrial emissions, it has growing relevance to agriculture through:

Bioenergy production
Biomass energy systems
Anaerobic digestion facilities
Carbon farming initiatives
Net Zero agriculture strategies

Agricultural sectors are increasingly exploring how carbon capture technologies can complement natural carbon sequestration through soils, woodlands and agroforestry systems.

Carbon Capture and Storage in the UK

The UK government has identified CCS as a key component of its Net Zero strategy.

Major UK CCS priorities include:

Industrial decarbonisation
Hydrogen production
Carbon storage infrastructure
Negative emissions technologies
Climate change mitigation

Several large-scale carbon capture and storage projects are currently being developed across the UK to support long-term emissions reduction goals.

Carbon Capture and Storage in Europe, USA & Globally

Europe

European countries are investing heavily in CCS technologies as part of climate action and industrial decarbonisation strategies.

United States

The US has some of the world's largest operational CCS projects and continues to invest in carbon capture innovation.

Global

Globally, CCS is recognised by organisations such as the IPCC and International Energy Agency (IEA) as an important technology for achieving climate targets.

Many governments view CCS as a critical component of future low-carbon energy and industrial systems.

Carbon Capture and Storage vs Carbon Sequestration

Feature	Carbon Capture and Storage (CCS)	Carbon Sequestration
Method	Engineered technology	Natural or engineered process
Storage	Geological formations	Soils, forests, oceans and geological storage
Focus	Industrial emissions reduction	Long-term carbon removal and storage

CCS is one form of carbon sequestration but uses engineered systems rather than relying solely on natural processes.

Carbon Capture and Storage vs Carbon Farming

Feature	Carbon Capture and Storage	Carbon Farming
Approach	Technological solution	Land management solution
Carbon Source	Industrial emissions	Atmospheric carbon
Storage Method	Underground geological storage	Soils, crops, trees and vegetation

Both contribute to climate mitigation but operate in different ways.

Benefits of Carbon Capture and Storage

1. Significant Emissions Reduction

Can capture up to 90% or more of carbon emissions from some industrial sources.

2. Supports Climate Goals

Helps governments and businesses meet emissions reduction targets.

3. Enables Cleaner Energy Production

Reduces emissions from power generation and industrial activities.

4. Protects Industrial Competitiveness

Allows key industries to transition towards lower-carbon operations.

5. Supports Negative Emissions

When combined with bioenergy or direct air capture technologies.

Challenges of Carbon Capture and Storage

1. High Costs

CCS infrastructure can require significant investment.

2. Infrastructure Requirements

Transport and storage networks must be developed.

3. Energy Demand

Some capture processes require additional energy.

4. Regulatory Oversight

Long-term monitoring and governance are essential.
