Blue Laser Fusion Plans To Commercialize Fusion Reactors Using Laser Technology By 2030

Recently, a San Francisco startup co-founded by Nobel Prize winner - Shuji Nakamura - plans to commercializefusion reactors using laser technology around 2030.
Shuji Nakamura, who won the 2014 Nobel Prize in Physics for his invention of the blue light-emitting diode, founded Blue Laser Fusion in November 2022 in Palo Alto, California. Partners include Hiroaki Ohta, former CEO ofmaker ACSL Ltd. The startup, which earlier raised $25 million, plans to build a small experimental reactor in Japan in 2024 in partnership with a Toshiba Corp. subsidiary. Japan is good at manufacturing, while the US is good at business and marketing, and they want to combine the strengths of both countries to build a fusion reactor, said Nakamura, a professor at the University of California, Santa Barbara.
Currently, Blue Laser Fusion plans to commercialize the fusion reactor, which could generate 1 gigawatt of electricity, equivalent to the output of an averagepower reactor. The cost of construction would be about $3 billion. And fusion technology is designed to replicate the process that occurs on the sun to produce large amounts of energy in a controlled manner. Unlikefission, fusion produces no radioactive waste, making it a promising source of energy not only for Earth but also for space missions. To initiate fusion ignition, researchers must heat the fuel to more than a million degrees Celsius, a feat they have accomplished using a variety of methods. The main challenge, however, is sustaining the reaction and producing more energy than is consumed in the fusion process. In their quest to sustain the fusion reaction,scientists use two main methods. The first involves magnetic confinement, in which powerful magnets are used to keep the plasma state of the fuel within a ring surface or donut shape. This method led to the creation of tokamak reactors and has attracted a great deal of interest and investment from companies and venture capitalists; the second uses lasers and fires them in rapid succession. However, the downside of this method is that large devices cannot fire lasers in a continuous pattern, and small devices cannot produce a high enough output to ignite fusion fuel. This is where blue laser fusion thinks it couald make a difference. Nakamura, who won a Nobel Prize for his pioneering work in developing blue light-emitting diodes, believes his company can use his semiconductor expertise to create a safe pathway for realizingfusion and turning it into a commercially viable technology. Specific details of the method remain undisclosed as Blue Laser Fusion is currently in the process of filing a patent application. However, Nakamura is confident in the feasibility of building a rapid-fire laser and envisions a one-gigawattreactor in Japan or the United States by the end of the century. Until that milestone is reached, the company intends to build a small pilot plant in Japan by the end of next year.
In the months since its inception, Blue Laser Fusion has filed more than a dozen patent applications in the United States and other countries. The company is also investigating the use of boron instead of deuterium as a fuel for fusion reactors. The company claims that boron is a more favorable choice as a fuel because it does not produce harmful neutrons. Blue Laser Fusion has also partnered with other Japanese companies, such as Toshiba Energy Systems & Solutions, a manufacturer of turbines forpower plants, and Tokyo-based YUKI Holdings, which provides metal fabrication services.2022 In December, the Lawrence Livermore National Laboratory in the U.S. successfully demonstrated the use of lasers to generate more energy from thefusion process. Nonetheless, this achievement is only momentary, and for blue laser fusion to be commercially viable, they must demonstrate long-term sustainability.
