Why is Google Investing in Nuclear Fusion With TAE?
Google has taken a strategic leap towards integrating sustainable energy solutions by investing in TAE Technologies, a company pioneering commercial nuclear fusion energy.
The innovative leap focuses on the technological requirements and advancements needed for harnessing nuclear fusion, a process called upon to emulate the sun's energy generation through the fusion of light atomic nuclei.
TAE Technologies, which has been backed by Google's for a long time, has accumulated almost US$1.3bn in equity since its inception in 1998, pushing forward in the pursuit of viable fusion power.
Google, having contributed to the firm's funding rounds since 2015, has helped to establish TAE as a frontrunner in this field.
“We’ve been an investor in TAE since 2015 and recently participated in its latest funding round, positioning them as a leading contender in the race to achieve fusion," says Ross Koningstein, Engineering Director Emeritus at Google Research.
“We’re delighted to continue our relationship with Google, who have not only provided funding to TAE but collaborated closely in research and development over many years," says Michl Binderbauer, CEO of TAE.
"With this latest fundraise, we look forward to accelerating our efforts to deliver commercial fusion power.”
The potential of fusion energy
As one might expect, creating sustainable fusion energy is a complex ordeal.
Fusion offers the promise of generating energy four times greater per kilogramme than current fission processes, according to the International Atomic Energy Agency.
But reproducing these extra-terrestrial conditions on Earth means overcoming substantial technical hurdles like plasma stability and heat management.
TAE's pioneering technology seeks to address these challenges through its unique Field-Reversed Configuration (FRC) approach, which aims to optimise plasma confinement while maintaining cost-efficiency.
The "Norm" breakthrough achieved by TAE involved reaching more than 70,000,000°C using a simplified device. This was accomplished through neural beam injection for a stable FRC plasma, minimising associated costs and complexities.
Google's vision
Google’s interest in fusion is driven by a need to curtail its rising greenhouse gas emissions and energy consumption associated with its expanding data centres.
“In 2023, our total GHG emissions increased 13% year-over-year, primarily driven by increased data centre energy consumption and supply chain emissions," says Kate Brandt, Google's Chief Sustainability Officer.
It aims for net zero emissions by 2030, making clean energy alternatives like fusion a long-term goal for its operations.
“We’ll need to take many shots on goal in this next frontier of energy innovation: that means accelerating advanced energy solutions to unlock new clean firm capacity within the next decade, as well as longer-term bets like nuclear fusion," says Michael Terrell, Head of Advanced Energy at Google, in a LinkedIn post.
The role of TAE Technologies
Since 2015, Google Research has actively participated in enhancing TAE’s scientific outcomes using AI to improve plasma temperature and sustain its lifetime.
The partnership has enabled the development of sophisticated plasma reconstruction algorithms and tools such as the "Optometrist Algorithm" that further its frontier work in fusion energy.
Google's integration of AI not only aids in tackling the technical aspects of fusion energy but also complements the company's initiative in reducing its carbon footprint and fostering a cleaner energy ecosystem for the future.
