Quotations

"The grid is getting less and less certain, so the ability to see things not statically, but as a probability — hence all the utility actions — should be risk informed."

Josh Wong, founder and CEO of ThinkLabs

"That hits not just reliability objectives, but also affordability, so we know how to maximize and optimize investments."

Josh Wong, founder and CEO of ThinkLabs

"Nuclear is a known technology we’ve been doing for 50 to 60 years, but the way we’ve been doing things simply will not scale to meet the moment that’s in front of us; it needs to be reinvigorated by artificial intelligence."

Trey Lauderdale, founder and CEO of Atomic Canyon

"Using these batteries with our power electronics and systems control software, you can make a highly responsive power source that can deal with the novel fluctuations of AI training."

Colin Campbell, chief technology officer of Redwood Materials

"Twenty years ago, our founders, including Bill Gates, realized that emissions avoidance should also be a part of this energy solution."

Chris Levesque, president and CEO of TerraPower

"With fusion, there’s no running out of control."

Brandon Sorbom, cofounder and chief science officer of CFS

"It is passively safe, since the default mechanism is shutting itself down."

Brandon Sorbom, cofounder and chief science officer of CFS

"We will be able to build a first-of-its-kind plant that will be cost-competitive with both renewable and nonrenewable sources of energy."

Brandon Sorbom, cofounder and chief science officer of CFS

Long-term implications

The long-term implications involve a more robust, efficient, and decarbonised energy system capable of supporting significant AI infrastructure growth. AI-driven grid optimisation, advanced nuclear technologies, and innovative battery storage solutions could lead to a stable, low-carbon energy supply, faster integration of clean energy sources, and potentially lower overall energy costs as these technologies mature and scale, ultimately facilitating a more rapid transition away from fossil fuels.

Frequently asked questions

How is AI improving grid management?

ThinkLabs AI uses digital twins and agents powered by NVIDIA CUDA to simulate grid conditions and identify solutions, reducing the time required to evaluate grid interconnection applications from 30-45 days to two minutes, thereby speeding up clean energy integration and optimising the grid for variability.

Can AI help with nuclear energy production?

Yes, Atomic Canyon employs NVIDIA-accelerated AI platforms (Neutron and NIVA) to streamline nuclear power plant operations by converting operational data into a knowledge layer. TerraPower uses an NVIDIA Omniverse-powered platform to create digital twin software, accelerating the siting and delivery of future Natrium reactors from years to months.

How are AI factories addressing their increasing energy demand?

Redwood Materials is tackling the accelerating electricity demand from AI by providing large-scale, off-grid power solutions. They repurpose 100% recycled electric vehicle batteries, integrated with an AI intelligence layer running on the NVIDIA Blackwell platform, to provide real-time adaptable power directly to data centres, reducing reliance on the main grid and lowering costs.

What is AI's role in advancing fusion energy?

Commonwealth Fusion Systems (CFS) leverages NVIDIA Omniverse libraries and OpenUSD to compress years of experimentation into weeks for its SPARC tokamak demonstration fusion machine. This AI-driven simulation helps in replicating the sun’s power source on Earth, accelerating the development of carbon-free, passively safe fusion energy.
