Fusion Startup Gets an AI Boost From Nvidia and Siemens

Welcome back: A Bill Gates-backed nuclear fusion company has teamed up with tech giants Nvidia and Siemens in an effort to bring the energy that powers the sun a step closer to commercial reality.

WSJ Pro Sustainable Business's Clara Hudson reports that Commonwealth Fusion Systems is working with the tech companies to develop a virtual replica of CFS’s nuclear fusion machine, courtesy of Nvidia’s and Siemens’s AI and industrial software might. Fusion engineers will use this “digital twin” to run simulations, ultimately to hasten the goal of producing fusion energy at a commercial scale.

Nuclear fission, which splits atoms to produce energy, is already in use in power plants, but many companies see fusion, the energy process that powers the sun by joining atoms together, as a longer-term bet because it can provide much more renewable energy in a cleaner process.

CFS, which is backed by Gates’s Breakthrough Energy Ventures fund, says it is aiming to start producing commercial fusion energy in the 2030s.

“We’re not going to be flying by the seat of our pants; we’re not going to be flying blind.”

Chart of the Day

Venezuela is estimated to have the world’s largest oil reserves but today it produces just 1 million barrels per day (b/d), down from nearly 4 million b/d in the 1970s. The decline reflects deep-rooted troubles in the oil sector and the country. Huge capital expenditure over many years is needed to raise output meaningfully, according to analysis from Oxford Analytica.

 

The Fight Over Making Data Centers Power Down to Avoid Blackouts

A surge in data-center development has pushed electricity prices higher and increased the threat of blackouts in some parts of the U.S. Ana Elisa Sotelo for WSJ

Power-hungry data centers risk pushing parts of the U.S. grid toward failure. Some technology companies are fighting a potential solution: disconnecting the data centers from the grid when electricity is in short supply.

The Wall Street Journal's Katherine Blunt writes that across the U.S., tensions are mounting as companies including Google, Amazon.com and Microsoft debate with utility executives whether their electricity needs can be met without causing blackouts during times of extreme demand.

Officials have raised concerns that the grid isn’t equipped to handle the number of data centers tech companies are seeking to build. They say it will take years to build new transmission lines and power plants needed to support the surge in demand while keeping the lights on for other users.

America’s Biggest Oil Field Is Turning Into a Pressure Cooker

Shale drillers have turned the biggest oil field in the U.S. into a pressure cooker that is literally bursting at the seams.

The Journal's Benoît Morenne and Andrew Mollica report that producers in the Permian Basin of West Texas and New Mexico extract roughly half of the U.S.’s crude. They also produce copious amounts of toxic, salty water, which they pump back into the ground. Now, some of the reservoirs that collect the fluids are overflowing—and the producers keep injecting more. It is creating a huge mess.

A buildup in pressure across the region is propelling wastewater up ancient wellbores, birthing geysers that can cost millions of dollars to clean up. Companies are wrestling with drilling hazards that make it more costly to operate and complaining that the marinade is creeping into their oil-and-gas reservoirs. Communities friendly to oil and gas are growing worried.
