Buried deep within Accelleron's Q4 2023 earnings transcript lies a subtle, yet potentially earth-shattering revelation. While analysts are busy dissecting the company's solid financial performance and revised capital allocation strategy, a more profound narrative is unfolding: Accelleron's aggressive bet on fuel injection technology, specifically within the burgeoning realm of dual-fuel engines powered by methanol and ammonia.

This isn't just about incremental growth; it's about seizing a dominant position in a nascent market with the potential to reshape the global energy landscape. As Daniel Bischofberger, Accelleron's CEO, aptly points out, the world needs a staggering 600 million tons of green hydrogen annually just to decarbonize hard-to-abate industries like shipping, aviation, and steel production. This translates to an astronomical $9 trillion investment in green hydrogen infrastructure over the next 26 years.

And here's where Accelleron's strategic brilliance comes into play. They recognize that the maritime industry, a bellwether for other hard-to-abate sectors, is actively preparing for this green hydrogen revolution. Ship owners, spurred by IMO's net-zero targets and the EU's carbon pricing scheme, are increasingly opting for dual-fuel vessels capable of running on alternative fuels like methanol and ammonia. As of the end of 2023, a remarkable 50% of new ship orders were for vessels with alternative fuel capabilities.

This dual-fuel engine trend plays directly into Accelleron's hands. Not only does their core turbocharger business benefit from the increased demand for fuel efficiency and flexibility in a world of expensive new fuels, but their fuel injection technology, bolstered by the acquisition of OMT, is poised for explosive growth. Why? Because dual-fuel engines require two complete fuel injection systems, one for diesel and one for the alternative fuel.

Furthermore, these new fuel injection systems are significantly more complex and expensive due to the handling requirements of methanol and ammonia. Bischofberger estimates that this "content increase" for dual-fuel engines is significantly higher than just double the cost of a traditional diesel injection system. He describes a world where traditional diesel injectors are augmented with three additional injectors per cylinder, each with its own high-pressure pump due to the hazardous nature of ammonia and methanol.

Accelleron isn't just riding this wave; they're investing heavily to become the dominant force. OMT, their fuel injection subsidiary, is already operating at full capacity with a year-long backlog. Accelleron is pouring capital into expanding OMT's production capacity through new hires, additional shifts, outsourcing, and equipment upgrades. They're even building a new R&D test center dedicated to developing new fuel applications for medium-speed engines, a segment where they currently have a limited presence.

The company is clearly aiming to capitalize on the "window of opportunity" created by the shift to new fuels, particularly in the four-stroke engine market. Unlike the two-stroke engine segment, where Accelleron mainly manufactures fuel injection systems based on licensed designs from engine manufacturers, the four-stroke segment offers the potential for exclusivity. By securing development contracts with engine builders for methanol and ammonia fuel systems, Accelleron can establish itself as the sole supplier, locking in long-term revenue streams.

While Accelleron's guidance for 2024 might seem conservative, with organic revenue growth projected at a modest 0-2%, this likely reflects the cyclical cooldown in their core gas compression and merchant marine businesses. The real story lies in the fuel injection segment, where the company is quietly building a powerhouse capable of capitalizing on the massive $9 trillion green hydrogen infrastructure boom.

Accelleron's commitment to innovation, coupled with their strategic acquisitions and aggressive capacity expansion in fuel injection, suggests they're not just content with being a leading turbocharger manufacturer. They're laying the foundation to become a key enabler of the green hydrogen revolution, a position that could propel this century-old Swiss powerhouse to unprecedented heights.

Hypothesis and Numbers

Explosive growth in fuel injection: Accelleron's fuel injection business, fueled by the dual-fuel engine trend, could see growth rates far exceeding the company's overall 4-6% revenue guidance. A doubling or tripling of OMT's current revenue within the next 3-5 years is a plausible scenario.

Margin expansion in fuel injection: Due to the higher complexity and pricing of new fuel injection systems, OMT's operational EBITDA margin could significantly exceed Accelleron's group-level margin of 24.5%. Margins of 30% or higher are within reach.

Valuation re-rating: As investors recognize the growth potential of Accelleron's fuel injection business, a valuation re-rating is likely. The company's current P/E ratio of 36 could expand to 40 or higher, reflecting its dominant position in a rapidly growing market.
