Deep decarboniza.on scenarios will become twice as expensive to achieve if nuclear energy technologies are taken off the table. Advanced nuclear technologies with enhanced thermal systems can provide significant decarboniza.on. Furthermore, advanced nuclear technologies such as SMRs and microreactors can offer wider deployment of nuclear technologies from their flexible si.ng and reduced costs. New nuclear technologies can also be integrated with renewables such as hydrogen to form a more reliable and cleaner energy infrastructure. Addi.onally, as coal plants are re.red, new nuclear technologies can fill the demand gap for baseload power. In order to achieve this future of widespread new nuclear technology deployment and significant emissions reduc.ons, federal and state policies that drive carbon- free innova.on will be invaluable to helping industry commercialize and deploy these new nuclear technologies on a wide scale.
