A startup supported by Sam Altman has secured a substantial amount of funding, close to half a billion dollars, with the goal of constructing the world’s first nuclear fusion power plant to address the energy crisis. Helion Energy, based in the US, received a $425 million Series F investment from major investors such as Lightspeed Venture Partners, SoftBank, and Vision Fund 2, along with existing investors like Mr. Altman, Capricorn Investment Group, and others.
Having raised over $1 billion since its establishment in 2013, Helion aims to have the world’s first nuclear fusion power plant operational by 2028. The company has already secured a purchase agreement from Microsoft, a significant investor in Mr. Altman’s OpenAI.
“I am thrilled about the opportunities this funding will unlock for us. We will be significantly expanding our manufacturing operations in the US, allowing us to produce capacitors, magnets, and semiconductors at a much faster pace. This will expedite the construction of the world’s first fusion power plant and all future plants,” said David Kirtley, Helion’s co-founder and CEO.
Nuclear fusion is considered the ultimate solution for energy production, mimicking the process that powers the Sun by merging atomic nuclei to generate vast amounts of energy. Helion’s latest prototype, Polaris, operates at temperatures exceeding 100 million degrees Celsius, with the ambition of generating electricity from it.
China’s nuclear fusion reactor
In a significant development, scientists at China’s Experimental Advanced Superconducting Tokamak (EAST) fusion energy reactor, known as the ‘artificial sun’, managed to sustain plasma for a remarkable 1,000 seconds, surpassing their previous record of 403 seconds set in 2023.
This achievement represents a crucial step towards enhancing the technology, although the reactor has not yet achieved ignition, where nuclear fusion can sustain itself. The prolonged stabilization of plasma loops is seen as a positive sign for the future of fusion power.
