Although much of the talk about clean and environmental tech focuses on topics such as climate change software, electric cars and new battery technologies, investors seem to have found a new favorite in a concept that has been talked about for a century.

The promise of real commercialized fusion energy seems to have fired up some venture and investment firms which are now betting big鈥攙ery big in some cases鈥攊n the space. Just earlier this month, Cambridge, Massachusetts-based raised a huge Series B of more than $1.8 billion led by and also included investments from , and about two dozen others.

While the round marks the largest for any nuclear fusion startup鈥攁ll of which are vying to create carbon-free energy鈥攊t was far from the only one.

In early November, Everett, Washington-based closed a $500 million Series E led by 鈥攚ith an opportunity for an additional $1.7 billion tied to reaching performance milestones. Then a day before Commonwealth announced its massive round, British Columbia-based raised a $130 million Series E led by 鈥嬧�� and included an investment by .

Although it may seem the flood of investment dollars is due to the trend toward more eco-conscience investment, those in the fusion industry see something else also driving it. That is mainly the fact we likely are now years鈥攏ot decades鈥攁way from commercializing carbon-free energy.

How close?

Before laying out a timeline for fusion, it probably is important to understand what it is. In its most simplistic explanation, fusion energy is created when two atoms are merged鈥攖hat merging causes a release of energy which in theory can be harnessed and has zero carbon emissions.

鈥淵ou are talking about the holy grail of energy,鈥� said Scott Krisiloff, Helion鈥檚 chief business officer.

Helion plans to use its new cash to help complete the construction of Polaris鈥攊ts seventh-generation fusion generator鈥攚hich it broke ground on in July. The company is aiming to use Polaris to demonstrate net electricity production in 2024.

Krisiloff said that time frame is possible due to other technology advancements in the last decade-plus that have made Helion鈥檚 technique for fusion possible. Things such as new switches and even modelling software that did not exist several years ago have made commercializing fusion energy more of a reality than ever before.

鈥淭here is lot of enabling tech that has more recently been developed that has made our approach possible,鈥� he said,

Similarly General Fusion is hoping to be able to demonstrate the ability to economically produce fusion conditions by 2025 at the U.K. facility it is building. , the company鈥檚 CFO, said progress in areas such as plasma physics and other tech have made the company’s target timeline possible.

鈥淭here鈥檚 just been significant advancement in the past 10 years,鈥� said Twinney, mentioning improvement in advanced computing and 3-D printing in particular.

More is needed

While tech advancements have played a role in fusion鈥檚 rebirth with investors, another driver that has field new investment is the realization that while many first-gen cleantech renewable energies may help the battle climate change, alone they will not be enough.

鈥淭here is now the recognition of the global imperative to fight climate change,鈥� Krisiloff said. 鈥淎nd wind and solar alone just cannot produce all the power we need.鈥�

, founder and chief investment officer at 鈥攚hich is an investor in General Fusion鈥攕aid while everything from EVs to new wind tech will be needed to battle climate change, his firm has remained bullish on nuclear fusion due to what success would mean in the field.

鈥淚nvestors are realizing the limitations of renewables,鈥� he said. 鈥淔usion will be unrivaled in terms of clean, zero-waste energy. It has been overlooked for 10 years as people have focused on other things.鈥�

Rodman said the flood of new investment also is due to the fact that fusion is no longer just theories or small scale models.

鈥淚f it was still in the garage phase, you would not see this amount of capital,鈥� he said.

Twinney said it is not at all out of the question that there could be a commercial fusion facility fully up and running by the end of this decade; meaning decades of promise could finally pay off for both developers and investors.

鈥淚t is important to enter these investments with a realistic timeline,鈥� said Rodman, adding that while revenue production may be years away, there is a significant value in demonstrating the ability to disrupt a multitrillion-dollar energy sector.

鈥淲e have a detailed day-by-day gameplan,鈥� he said. 鈥淭his is a very exciting time in the space.鈥�
