Fund II enables larger, institutional investors to participate meaningfully in the energy transition
Fund II focuses on the ventures innovating in next-generation nuclear and carbon management technologies that are developing the technologies that are critical to our ability to phase out fossil fuels yet maintain reliable and resilient grids. Until recently, these ventures have been widely overlooked by mainstream venture investors. However, now that large energy users like Google, Amazon and Microsoft have committed to quantity purchases of nuclear power and others are following closely behind them, it is becoming much easier to identify the vital importance of these emerging sectors. Yet it remains quite difficult to evaluate the growing number of ventures seeking to introduce advanced nuclear products or services. That's where Nucleation Capital, with decades of industry experience, comes in. We are building an expertly-curated portfolio of holdings for investors looking to add advanced nuclear to their clean energy exposure. The market is demanding nuclear and the Trump Administration is facilitating accelerated licensing. This is the time to jump in. Nucleation is now raising a $250+ million Fund II, with a $5 million minimum and a first close at $150 million. We expect to make 20 to 25 investments over a 3 year invest period, reserving 30% of funds raised in excess of $150 million for follow-on rounds.
Get broad exposure to next-generation nuclear
If you are managing a large portfolio, you likely have some fossil fuel exposure, renewable energy holdings and likely both. You may even have a little traditional nuclear power in your portfolio through the public markets. But chances are very low that you have much if any exposure to the next generation of nuclear energy innovators, who are on the cusp of commercializing new technologies. Nucleation Fund II is the way to gain that exposure through a curated and structured portfolio.
Nucleation Capital brings broad nuclear knowledge and decades of industry experience to our diligence and selections of top prospects for our portfolio. We invest exclusively in highly promising private innovative ventures developing advanced nuclear, deep decarbonization and grid enhancement technologies, technologies that are vital to our ability to transition away from carbon-emitting fossil fuels—and doing so without sacrificing energy reliability or affordability. Nucleation’s unique pronuclear thesis—with a focus on next-generation fission and fusion nuclear energy technologies—emerged because there were no other investment vehicles providing access to these nascent deeptech climate technologies. We've now been investing in this space for more than four years and, in this time, our thesis has been validated and even more investors are seeking access.
Today, although nuclear fission has been commercial for almost 70 years, generates about 20% of U.S. electricity, and 50% of our total clean energy, most funds don't invest in nuclear in any way. There are 30 countries using nuclear fission to generate power, and nearly all recently committed to tripling that. In May, Trump announced a plan to quadruple nuclear power in the U.S. and issued four powerful Executive Orders that seek to propel progress. Additionally, there are about 30 "nuclear newcomer" countries seeking to deploy nuclear for the first time. Meanwhile, over 200 countries agreed to transition away from fossil fuels. So, the market is ripe for new solutions and the prospects for advanced, Gen IV reactor designs are growing.
Investing into traditional nuclear players is possible through public markets, investing in the advanced nuclear sector developing a range of Gen IV reactors is surprisingly difficult. That's where Nucleation Capital comes in. We offer this fund as the best, most efficient way larger investors can build a well-structured, expertly curated and risk-reduced portfolio to gain concentrated exposure to next-generation nuclear and advanced carbon management ventures.
