Is CCUS and Green Hydrogen Considered Renewable Energy?

Renewable energy sources have gained significant attention in recent years as the world seeks sustainable alternatives to traditional fossil fuels. Among the emerging technologies are Carbon Capture, Utilization, and Storage (CCUS) and green hydrogen. Both are touted as potential solutions to reduce greenhouse gas emissions and combat climate change. However, the question remains: Are CCUS and green hydrogen truly considered renewable energy? Let’s delve into the details and explore the intricacies of these technologies.

CCUS: The Promise of Reducing Carbon Footprint

Carbon Capture, Utilization, and Storage (CCUS) is a technology that aims to capture carbon dioxide (CO2) emissions from industrial processes or power plants and store them permanently underground or put them to use in other industries. The idea behind CCUS is to prevent CO2 from entering the atmosphere and contributing to global warming. By capturing and storing carbon emissions, CCUS has the potential to significantly reduce the carbon footprint of various industries.

CCUS technology encompasses three main steps: capture, utilization, and storage. The capture phase involves separating CO2 from other gases emitted during industrial processes, such as power generation or cement production. The captured CO2 can then be utilized for enhanced oil recovery or in industries that require carbon dioxide. Finally, the CO2 is transported to storage sites, usually deep underground, where it is stored permanently, reducing its impact on the environment.

While the intention behind CCUS is to reduce greenhouse gas emissions and mitigate climate change, it is important to note that the technology itself does not generate energy. CCUS is an add-on technology that captures and stores CO2 emitted from fossil fuel-based power plants or industrial processes. Therefore, it is not considered a source of renewable energy on its own.

Green Hydrogen: A Clean Fuel for the Future

Another technology that has garnered attention as a potential solution to reduce greenhouse gas emissions is green hydrogen. Unlike conventional hydrogen production methods, which rely on fossil fuels and emit CO2, green hydrogen is produced using renewable energy sources, such as solar or wind power.

The process of producing green hydrogen involves electrolysis, where water molecules are split into hydrogen and oxygen using electricity. The electricity used for this process is generated from renewable sources, ensuring that the hydrogen produced is carbon-free. Green hydrogen can be stored and transported, and it can be used as a fuel in various sectors, such as transportation, industry, and power generation.

Green hydrogen is considered a promising solution for decarbonizing sectors that are challenging to electrify directly, such as heavy-duty transportation or certain industrial processes. It offers a clean alternative to conventional fuels, reducing greenhouse gas emissions and contributing to a more sustainable future. However, it is crucial to clarify that green hydrogen is not a direct source of renewable energy itself but rather a means of storing and utilizing renewable energy.
