Climate tech startups have traditionally faced significant challenges, including high capital requirements and lengthy development timelines, with many technologies being groundbreaking in nature. Furthermore, these startups often tackle pollution—an external cost that the market inadequately values—making them less appealing to stock investors. Despite these hurdles, there is growing interest in climate tech within public markets.
Recently, nuclear startup X-energy went public, securing $1 billion through an oversubscribed share offering, much to the delight of its investors, including Amazon. The stock soared by 25% within the first hour of trading. Similarly, geothermal startup Fervo announced its intention to launch an initial public offering, reportedly valued at around $3 billion by private investors, although the exact size of the IPO remains undisclosed.
This shift towards public offerings reflects sentiments previously shared by investors, who predicted a resurgence of interest in energy-related startups after a prolonged period of hesitance towards climate tech ventures. Many investors pinpointed nuclear fission and enhanced geothermal as promising sectors, with Fervo frequently highlighted.
The surge in interest can be attributed partly to data centres, as the current AI boom has generated an increased demand for electricity, creating a compelling narrative for energy-related startups. These companies find themselves in a favourable position, coinciding with technological advancements and market readiness.
The encouragement from successful IPOs is likely to satisfy investors keen on returning capital to their limited partners, especially since many funds have been unable to cash out due to a decline in IPO activity. Nonetheless, the motivations extend beyond mere capital recovery.
Fervo and X-energy’s conventional route to public markets implies a healthy investor appetite for climate tech. While some startups have pursued the quicker SPAC (Special Purpose Acquisition Company) route, these companies chose the more arduous process of traditional listings, signalling confidence in broader investor engagement.
However, numerous climate tech firms not anchored in energy markets may miss out on the IPO trend. This divergence indicates an emerging K-shaped recovery within the sector, as noted by Mark Cupta of Prelude Ventures. Companies lacking direct energy market connections will need to explore alternative funding avenues, often facing constraints from increasingly competitive private investment landscapes.
Venture capital and growth funds raised $6.5 billion last year, maintaining levels from 2021. Yet the number of funds has risen, diluting the amount available to each, which could hinder startup financing. Conversely, larger funds are amassing more capital, with 75% of climate tech funds’ total raised last year coming from just 42 infrastructure funds, which tend to focus on renewables and energy storage.
This evolving landscape suggests that the K-shaped trend in climate tech funding will persist, with only companies boasting mature technologies likely to thrive amid mounting competition and shifting investment dynamics.
