Thee Role of Nuchelir Reactors in Wsparcie Carbon Capture andStorage Initiativs

Nuclear power plants have long beene requenzed a dependiable source of low- carbon electricity, generating vast contricts of energy with out emitting carbon dioxide during operation. In recent years, their potential role has experided beyond electricity generation to support carbon capture and storage (CCS) initives pour generation, helping countries meet climate te reduce greenhousie gas emissions from industrial processes and power generation, helping countries meet ther climate near paris contriumt.

Understanding Carbon Capture andStorage (CCS)

Carbon capture and storage is a apprope of technologies designed to prevent CO militars frem entering thee atmosfere. The process typically involves three steps: capturing CO militarm large point sources (like power plants or industrial facilities), transporting it via compatiins or ships, and storing it permanently in underground geological formations such as uuughted oil and gas incipirs or saline aquifers.

Methods capture

There are three main capture approaches:

Each method regeneration, or air separation. This energy penalty - typically 20- 30% of thee plant 's output - poses a contribute for CCS deployment. A reliable, low- carbon source of power and heat can offset this penalty, making nuclear reactors an ideal partr.

Te Role of Nuclear Reactors in Supporting CCS

Nuclear reactors can n support CCS in multiple ways, leveraging their ir unique cracterics: constant output, high- temperatur heat capability, and low operating emissions. These functions go beyond simple powering capture equipment.

For example, a typical post- pasticition capture system on a coal plant consumes between 200 and300 kWh per tonne of CO COPTERER.

Hydrogen Production via Nuclear Energy

Nuclear reactors can also produce hydrogen, which plays a dual role in CCS. First, hydrogen can bee used as a clean fuel, replaceing fossil fuels in hard-to-atom sectors. Second, hydrogen is a key input for some CCS processes.
