Nuclear power has a unique opportunity to stage a comeback amid the global energy crisis, soaring fossil fuel prices, energy security challenges & increased climate ambitions

But whether this happens will depend on governments & industry

New from @IEA ⬇️ iea.li/3ywoMzt

A nuclear power comeback is far from guaranteed

In advanced economies that see a role for nuclear, governments need to enact policies to kick-start investment

And the nuclear industry has to overcome recent cost overruns & delays to deliver new projects on time & on budget

In @IEA’s #NetZero2050Roadmap, global nuclear power capacity doubles by mid-century in a system dominated by renewables

To fulfil this role, nuclear's costs in advanced economies must come down by 40% and world nuclear investment triple by 2030

As things stand, advanced economies have lost their market leadership in nuclear power

Of the 31 nuclear reactors that started construction since 2017, all but 4 are Russian or Chinese designs

Reaching net zero emissions with less nuclear power than envisioned in the @IEA pathway would be harder and cost consumers $20 billion more a year to 2050

At the same time, deep nuclear cost reductions can open new opportunities to produce electricity, heat & hydrogen

Increased efforts to meet the world’s climate challenge have stimulated a burst of activity in small modular reactors (SMRs)

The lower costs, smaller size & reduced project risks of SMRs may improve social acceptance & attract more private investment versus large nuclear plants
