Fusion energy, the process that powers the sun, has long been the holy grail of clean energy. Recent advancements suggest that this elusive goal is within reach. In December 2022, scientists at the National Ignition Facility (NIF) in California achieved a significant milestone by producing more energy from a fusion reaction than was used to initiate it. This "ignition" event demonstrated the potential of fusion as a nearly limitless and clean energy source. However, challenges remain, including sustaining the reaction and developing materials that can withstand the extreme conditions inside a fusion reactor. en.wikipedia.org
The private sector's involvement is also propelling fusion energy forward. Companies like Commonwealth Fusion Systems (CFS) are developing compact fusion reactors using high-temperature superconducting magnets to stabilize superheated plasma. CFS aims to achieve net energy production by 2027, with plans to deliver power to the grid in the early 2030s. This rapid progress is attracting substantial investment, with over $7 billion in private funding globally. Governments are also recognizing the potential of fusion energy; for instance, Wisconsin has allocated $2 million to study optimal locations for a fusion power plant and established a board to promote nuclear and fusion technology. time.com, apnews.com
