Helion Fusion Round Grows to $500M Amid Microsoft Timeline Uncertainty
Helion Energy, a fusion startup aiming to commercialize clean energy, has grown its funding round to $500 million after adding $35 million in new investments. The company's Series G round was initially announced in June with a total of $465 million.
The addition brings the total investment in Helion to over $1.5 billion. Co-founder and CEO David Kirtley said the new funding demonstrates the growing demand for fusion energy and confidence in the company's ability to deliver it.
Helion is racing to meet its ambitious timeline, having signed a deal with Microsoft three years ago to supply energy to a Central Washington data center by 2028. However, full capacity might not be hit until 2030, according to Axios, which cited a Helion executive and raised questions about the company's ability to produce sufficient energy from its fusion devices.
Kirtley remains bullish on the company's trajectory, attributing technical challenges as the most important factor to resolve. The startup is working on resolving these issues with the help of Tiny Merge, a small-scale testbed device it's building at its R&D facility.
