Nuclear energy represents a vital solution in our quest to decarbonize hard-to-abate sectors. While electrification with clean power can largely decarbonize buildings and mobility, other options are needed to replace fossil fuels in heavy industries, aviation and shipping. Nuclear power, with its 24-7, low emissions operation, offers a compelling solution. It can produce heat for industrial applications as well as hydrogen, unlocking fossil-free alternatives in aviation and shipping. Integrating nuclear energy into the clean energy portfolio is essential for tackling the toughest abatement challenges and achieving a sustainable, low-carbon future.
