Sweden adopts “100% fossil-free” target

Sweden has done something very few countries or jurisdictions have done with respect to energy: they have kept their eye on the goal. The Swedish Parliament adopted an energy target of "100% fossil-free" energy—which should be everyone's goal—rather than falling into the trap of focusing on and dictating the means to that goal. This is so rare, it deserves recognition.

In Sweden adopts '100% fossil -free energy target, easing way for nuclear, EURACTIV reports on Sweden's new plan to remove their "100% renewable" target in order to use all available clean energy resources—including nuclear—to meet the expected doubling of energy demand while also meeting a net zero emissions goal by 2045.

“This creates the conditions for nuclear power,” Finance Minister Elisabeth Svantesson said in parliament. “We need more electricity production, we need clean electricity and we need a stable energy system.”

This new policy gives a green light for the government to push forward with plans by state-owned utility, Vattenfall, to build new small modular nuclear reactor plants and refurbish the country's existing plants to extend the their operating lives. Meanwhile, they are also working to simplify environmental permitting to speed up not just the build-out of nuclear but also for wind power and to accelerate other green technologies.

This is a very significant and promising change of focus which every country should adopt, while allowing utilities to find the best path forward for eliminating their use of fossil fuels. As far as we can tell, nothing else will enable the transition to move ahead at maximum speed.

Warming towards cold fusion

In Fusion Runs Hot and Cold, Jonah Messinger, the Breakthrough Institute's Senior Energy Analysist, provides a comprehensive overview of the state of the science of low energy nuclear reactions (LENR), a field once known as "Cold Fusion." Although long castigated as a pseudoscience, the field has attracted a growing number of credible experts, recent DOE funding, and has produced a growing body of empirical evidence for a phenomena that is becoming increasingly understood as a third type of nuclear power.

Cold fusion has long been widely misunderstood, beginning with its flawed introduction by Martin Fleischmann and Stanley Pons, electrochemists at the University of Utah, as far back as 1989. They claimed to have induced fusion reactions of deuterium nuclei in a palladium foil by applying a current to drive electrolysis. Their electrolysis experiments—inspired by older anomalous reports of cold-fusion-like experiments in the 1920s—caused several sharp, multi-day bursts in thermal power output from their cells well above the electrical power of the input current or the total potential energy stored in the chemical bonds of the electrolyte.

There were multiple problems with Fleishmann and Pons’ work, which were revisited by Jonah Messinger, not least of which was a lack of both reproducibility and a lack of a theoretical explanation. According to this review, not five weeks after the initial claims—the field was proclaimed dead by speakers at the influential American Physical Society (APS), among which was a mocking rebuttal by Steven Koonin, then a professor of theoretical physics at Caltech—now notorious for his dismissal of climate change impacts.

Although at that time, the DOE’s panel to evaluate cold fusion opted against funding cold fusion research (despite evidence of neutron and tritium production that could not be explained), the body of scientific evidence since then has grown such that even the DOE has finally agreed to fund research. Catch up on the current state of scientific understandings about what is now far more widely believed to be a highly complex, multi-body, low energy nuclear reaction with this article from the Breakthrough Institute.

Support for nuclear power soars

Grist writes: "US support for nuclear power soars to highest level in a decade: As the country looks to decarbonize, nuclear’s popularity continues to climb." This is what Akielly Hu, Grist's News and Politics Fellow, reports following the release by Gallup of a survey that found that 55 percent of US adults support the use of nuclear power. This total is up four percentage points in a year, and "reflects the highest level of public support for nuclear energy use in electricity since 2012."

Among other findings, the survey found that Republicans are more likely to favor nuclear energy than Democrats, which partisan divide is particularly visible at the state level, with more pro-nuclear policies adopted in Republican-controlled states than left-leaning ones. Nevertheless, support for nuclear energy by Democratic is also on the rise, in part due to advances in nuclear technologies and new federal climate laws that clarify the fact that nuclear power is carbon-free energy and can help in efforts to solve climate change.

The Biden administration has identified nuclear energy as a key climate solution to achieve grid stability in a net-zero future. The administration is pushing for the deployment of advanced nuclear reactor models that improve on the safety and efficiency of traditional reactor designs. These designs will all be far more consistent and reliable than wind and solar energy, which vary depending on the weather. The broader shift in public opinion and, in particular, Democratic opinion toward nuclear energy, is at least partially a function of strong pronuclear leadership coming from the Biden Administration and the DOE under Secretary Jennifer Granholm.
