Complementary Technologies: Nuclear Innovations, Green Hydrogen, and CCUS

Complementary low-carbon technologies continue to mature, providing essential support for system reliability and decarbonizing sectors that are harder to electrify:

• The U.S. government’s recent approval of small modular reactor (SMR) fuel manufacturing facilities marks a significant milestone in expanding nuclear baseload capacity. This development is paired with quantum computing applications led by the Electric Power Research Institute (EPRI), which are projected to save $1 million per day by optimizing nuclear plant maintenance and reducing operational downtime.

• Green hydrogen projects are advancing rapidly. The Waaree Energies and ZFI facility in Uttar Pradesh, India, leverages renewable electricity to produce clean hydrogen, targeting decarbonization in heavy industry and transportation.

• Carbon capture, utilization, and storage (CCUS) technologies are evolving, with GE Vernova’s exhaust gas recirculation systems enhancing efficiency and enabling integration with concentrated solar power (CSP) and industrial processes.

• Breakthroughs in hydrogen engine technology, spotlighted in recent automotive tech developments, signal renewed potential for hydrogen as a versatile clean fuel across mobility and power sectors.

• Sector coupling strategies that integrate renewables, green hydrogen, and CCUS facilitate synthetic fuel production, crucial for reducing emissions in traditionally fossil-dependent industries.

• The European Union remains at the forefront, driving R&D and policy innovation to accelerate the deployment of these complementary technologies.
