Amazon has unveiled a $500 million investment and several new partnerships aimed at integrating nuclear energy into its operations to combat the growing carbon footprint associated with its data centers.

This announcement follows a trend among major tech firms, with Amazon joining the ranks of companies like Google and Microsoft in pursuing nuclear solutions. Earlier this week, Google secured a deal with Kairos Power for small modular reactors (SMRs), while Microsoft announced a public-private partnership with Constellation Energy to revive the Three Mile Island Unit 1 nuclear reactor in Pennsylvania.

In 2019, Amazon committed to powering all its global operations—including data centers, corporate offices, stores, and fulfillment centers—with 100% renewable energy by 2030. The company recently achieved this goal seven years ahead of schedule. However, Amazon acknowledged that the surge in demand for generative AI necessitates exploring diverse energy sources beyond initial projections, leading to its current focus on nuclear energy.

The new initiatives center on SMRs, which are compact nuclear reactors offering advantages such as quicker construction times and closer proximity to energy grids. Amazon's agreements include a collaboration with Energy Northwest in Washington to develop four SMRs, expected to produce 320 MW of capacity, with the potential to expand to 960 MW. Additionally, Amazon is working with Dominion Energy on an SMR project aimed at generating at least 300 MW in Virginia.

Furthermore, Amazon's investment in X-Energy will support the development of SMR reactors and fuel. Together, they plan to bring over 5 GW of new nuclear projects online across the U.S. by 2039, representing a significant milestone in the commercial deployment of SMRs.

Earlier this year, Amazon announced a partnership with Talen Energy to establish a data center adjacent to Talen’s existing nuclear facility in Pennsylvania, enhancing its access to carbon-free energy while ensuring the preservation of Talen’s reactor.
