IEA sees nuclear power generation doubling by 2030

DUBAI, October 29, 2022

The International Energy Agency (IEA) projects more than a doubling of nuclear generation by 2050, with at least 30 countries increasing their use of nuclear power, in the Net Zero Emissions by 2050 scenario of its latest World Energy Outlook (WEO). 
 
The IEA said the global energy crisis can be a historic turning point towards a cleaner and more secure future.
 
The global energy crisis is causing profound and long-lasting changes that have the potential to hasten the transition to a more sustainable and secure energy system, according to the IEA. "Today's energy crisis is delivering a shock of unprecedented breadth and complexity," it stated in the WEO.
 
"Energy markets and policies have changed as a result of Ukraine crisis, not just for the time being, but for decades to come," said IEA Executive Director Fatih Birol. 
 
"Even with today's policy settings, the energy world is shifting dramatically before our eyes. Government responses around the world promise to make this a historic and definitive turning point towards a cleaner, more affordable and more secure energy system," stated Birol.
 
In the Stated Policies Scenario (STEPS), global nuclear output increases from 2776 TWh in 2021 to 3351 TWh in 2030 and to 4260 TWh in 2050. However, nuclear maintains its current share of about 10% in total electricity generation. 
 
This scenario requires the completion of 120 GW of new nuclear capacity by 2030, as well as the addition of another 300 GW worth of new reactors between 2030 and 2050 in over 30 countries.
 
In the Announced Pledges Scenario (APS) scenario, around 18 GW of new nuclear capacity is added per year over the outlook period, over a quarter more than in the STEPS, but the higher level of electricity demand in this scenario means that the nuclear share of the electricity supply mix remains about 10%. 
 
In APS, nuclear generation increases to 3547 TWh in 2030 and to 5103 TWh in 2050.
 
In the Net Zero Emissions (NZE) scenario, lifetime extensions in the 2020s helps limit global emissions, and an average of 24 GW of capacity added each year between 2022 and 2050 more than doubles nuclear power capacity by 2050. In this scenario, nuclear generation increases to 3896 TWh in 2030 and to 5810 TWh in 2050. 
 
However, nuclear's share of the electricity mix declines to 8% in 2050 due to very strong growth in electricity demand in the NZE scenario.
 
The IEA notes that while clean energy investment rises above $2 trillion by 2030 in STEPS, it would need to be above $4 trillion by the same date in the NZE scenario. 
 
"Major international efforts are still urgently required to narrow the worrying divide in clean energy investment levels between advanced economies and emerging and developing economies," it stated.
 
"The continued role of nuclear power in the electricity sector relies on decisions to extend the lifetime of existing reactors and the success of programmes to build new ones," the IEA said. 
 
However, it noted that investment in nuclear power is "coming back into favour" in some countries. 
 
"There have been announcements of lifetime extensions for existing reactors, often as part of the response to the current crisis ... there is growing interest in the potential for small modular reactors to contribute to emissions reductions and power system reliability".
 
Commenting on the latest WEO, World Nuclear Association Director General Sama Bilbao y León said: "Nuclear is a cornerstone of the IEA's vision of a clean energy future. But nuclear energy has the potential to do much more than what the IEA sets out. A greater contribution from nuclear will be needed because nuclear has the potential to supply both electricity and heat, both of which will be vital to achieving full decarbonisation across all sectors."
 
"Nuclear energy is a proven technology with many economic, social and environmental advantages. A sound and sustainable clean energy future will need to make much greater use of its benefits," he added.-TradeArabia News Service
