“Fervo Energy today [6/10/25] announced the successful drilling and logging of its Sugarloaf appraisal well, an operational achievement that demonstrates the rapid advancement and scalability of enhanced geothermal systems (‘EGS’). The well was drilled to a true vertical depth of 15,765 feet and is projected to reach a bottomhole temperature of 520 °F after full thermal equilibration. Fervo completed the Sugarloaf well in just 16 drilling days, representing a 79% reduction in drilling time compared to the US Department of Energy baseline for ultradeep geothermal wells.

While drilling what is Fervo’s hottest and deepest well to-date, the company was able to achieve multiple drilling performance records, including a maximum bit run length of 3,290 feet, a maximum average rate of penetration (‘ROP’) of 95 feet/hour, and an instantaneous ROP of over 300 feet/hour at depths greater than 15,000 feet. These results expand the window for commercial viability of EGS into a significantly deeper and hotter regime, paving the way to deploy the technology outside of the western US.”

“The world’s largest and most influential development bank said on Wednesday it would lift its longstanding ban on funding nuclear power projects.

The decision by the board of the World Bank could have profound implications for the ability of developing countries to industrialize without burning planet-warming fuels such as coal and oil.

The ban has been formally in place since 2013, but the last time the bank funded a nuclear power project was 1959 in Italy. In the decades since, a few of the bank’s major funders, particularly Germany, have opposed its involvement in nuclear energy, on the grounds that the risk of catastrophic accidents in poor countries with less expertise in nuclear technology was unacceptably high.

The bank’s policy shift, described in an email to employees late on Wednesday, comes as nuclear power is experiencing a global surge in support.

Casting nuclear power as an essential replacement for fossil fuels, more than 20 countries — including the United States, Canada, France and Ghana — signed a pledge to triple nuclear power by 2050 at the United Nations’ flagship climate conference two years ago.”

“British aerospace group Rolls-Royce on Tuesday received backing from the U.K. government to build the country’s first small modular nuclear reactors.

The announcement follows a two-year selection process and reaffirms Britain’s embrace of nuclear power, particularly as it also pledged on Tuesday to invest £14.2 billion ($19.2 billion) to build the large Sizewell C power station in eastern England…

Britain’s center-left Labour government said the plans could support up to 3,000 jobs and power the equivalent of 3 million homes once the SMRs are connected to the grid in the mid-2030s.”

“Meta has cut a 20-year deal to secure nuclear power to help meet surging demand for artificial intelligence and other computing needs at Facebook’s parent company.

The investment with Meta will also expand the output of a Constellation Energy Illinois nuclear plant.

The agreement announced Tuesday is just the latest in a string of tech-nuclear partnerships as the use of AI expands. Financial details of the agreement were not disclosed.

Constellation’s Clinton Clean Energy Center was actually slated to close in 2017 after years of financial losses but was saved by legislation in Illinois establishing a zero-emission credit program to support the plant into 2027. The agreement deal takes effect in June of 2027, when the state’s taxpayer funded zero-emission credit program expires.

With the arrival of Meta, Clinton’s clean energy output will expand by 30 megawatts, preserve 1,100 local jobs and bring in $13.5 million in annual tax revenue, according to the companies. The plant currently powers the equivalent of about 800,000 U.S. homes.”
