Executive Overview
For decades, the global maritime shipping industry has served as the invisible backbone of international commerce, quietly hauling over 80 percent of the world’s traded goods across vast oceans. Yet, this critical engine of globalization carries a heavy environmental toll. Powered overwhelmingly by heavy fuel oils and massive marine diesel engines, the international shipping sector accounts for roughly three percent of global greenhouse gas emissions—a carbon footprint comparable to that of a major industrialized nation.
As international regulators, including the International Maritime Organization (IMO), tighten environmental mandates and push the shipping industry toward net-zero targets by 2050, maritime operators are scrambling for viable decarbonization technologies. While long-term solutions like green ammonia, methanol, and pure hydrogen fuel cells hold immense promise, they frequently require brand-new vessel designs, costly shipyard overhauls, and the construction of entirely new global bunkering infrastructure.
Enter Newlight, an ambitious San Francisco Bay Area-based startup that is challenging the status quo with a clever, pragmatic twist. Co-founded by Israeli Navy veterans Evyatar Cohen and Haran Cohen Hillel, Newlight has developed a compressed hydrogen-injection retrofit system that slashes diesel consumption and emissions by more than 20 percent. Rather than forcing shipowners to wait years for custom-built green vessels, Newlight’s technology can be retrofitted onto existing bulk carriers in less than two weeks without requiring a dry dock.
By continuously monitoring diesel engines down to the millisecond—optimizing combustion through precise, real-time hydrogen injection—Newlight has successfully completed its first major long-range commercial voyage. Backed by a newly secured $9 million seed funding round and early commercial contracts spanning a dozen vessels, the startup is poised to rewrite the rules of maritime efficiency, proving that meaningful environmental progress doesn’t always have to wait for the future; sometimes, it can be bolted onto the engines of today.
Detailed Chronology: From Naval Roots to Open-Ocean Validation
The genesis of Newlight is rooted in the demanding, high-stakes operational environments experienced by its founders during their service in the Israeli Navy. Dealing with complex propulsion systems and demanding logistical challenges instilled in Evyatar Cohen and Haran Cohen Hillel a profound appreciation for operational efficiency and mechanical reliability.
After transitioning from military service to the commercial technology sector, the duo recognized a glaring disconnect in the maritime industry’s approach to decarbonization. While shipping companies desperately needed to cut emissions, the capital expenditure required to transition entire fleets to alternative fuels was astronomical. They realized that any truly scalable solution would need to work with the ships currently traversing the oceans, rather than demanding a wholesale replacement of the global fleet.
The conceptual breakthrough led them to draw an unlikely pop-culture parallel: the iconic nitrous oxide injection systems popularized by the Fast & Furious film franchise. In those cinematic moments, a flick of a switch unleashes an explosive boost of power by supplementing an engine’s combustion process. Newlight’s system inverts that logic. Instead of chasing raw acceleration to beat competitors, Newlight uses compressed hydrogen to dramatically improve combustion efficiency, allowing the engine’s primary fuel intake to be throttled back.
The Milestone Voyage: Singapore to Ghana
The transition from theoretical engineering to tangible reality reached a critical juncture when Newlight partnered with Lomar Shipping, a prominent international shipowning and management company. The startup’s retrofitted hydrogen-injection system was installed on a 650-foot-long Lomar bulk carrier for a grueling, 8,500-nautical-mile commercial voyage originating in Singapore and terminating in Ghana.
Spanning roughly a month at sea, the journey served as the ultimate stress test for Newlight’s technology. Operating in unpredictable marine conditions—subject to fluctuating weather, variable loads, and the relentless pounding of open-ocean swells—the system performed flawlessly.
When the co-founders finally engaged the system for its first live run at sea, it was, by their own account, an intensely emotional experience. Years of laboratory research, computational modeling, and sleepless nights culminated in the quiet hum of an integrated marine engine running cleaner and leaner than ever before. Subsequent data analysis confirmed that the voyage was an unmitigated success: the hybrid hydrogen setup reduced fuel consumption by 24 percent and slashed carbon dioxide emissions by an impressive 28 percent.
Supporting Context & Metrics: How the Technology Works
To understand the engineering achievement behind Newlight’s retrofit system, one must examine the intricate mechanics of large-scale marine diesel engines. These massive powerplants are marvels of mechanical engineering, but their sheer size makes instantaneous adjustments notoriously difficult.
Newlight’s system bridges this gap through an advanced, real-time monitoring and injection architecture. The hardware and software suite constantly evaluates the operational state of the diesel engine, operating at a microsecond level to determine the absolute optimal moment to introduce hydrogen into the combustion chamber.
Key metrics tracked by the system include:
- Exhaust Temperature: Providing critical feedback on thermal efficiency and combustion completeness.
- Combustion Pressure: Monitoring cylinder dynamics to ensure peak mechanical performance without inducing damaging engine knock.
- Air Intake Pressure: Adjusting air-fuel ratios dynamically as atmospheric and load conditions shift.
Every time a piston moves within the engine’s massive cylinders, Newlight’s algorithm micro-adjusts the flow of hydrogen. Because hydrogen burns exceptionally fast and clean, its introduction optimizes the flame propagation of the primary diesel fuel. This allows the engine management system to actively reduce diesel fuel flow. As co-founder Evyatar Cohen explains, the system essentially tells the engine: "Hey, reduce the fuel flow to the engine, we don’t need as much because we have some nitrous—it’s just called hydrogen."
Financial and Operational Impact
For commercial shipping operators navigating razor-thin profit margins and volatile bunker fuel prices, the economic incentives of Newlight’s technology are just as compelling as the environmental benefits.
- Fuel Savings: By cutting fuel usage by upwards of 20% to 24%, the system can translate into massive operational expenditure reductions. According to startup estimates, high-utilization vessels can save as much as $500,000 annually in fuel costs.
- Installation Efficiency: Traditional green retrofits often mandate weeks or months in a dry dock, resulting in crippling vessel downtime and lost charter revenues. Newlight claims its system can be fully installed in less than two weeks, often while a ship is docked for routine cargo operations.
- Emissions Reductions: With international carbon taxes and compliance frameworks like the European Union’s Emissions Trading System (EU ETS) increasing the cost of fossil-fuel reliance, cutting CO2 emissions by over 25% offers shipowners a vital financial buffer.
Official Statements and Investor Confidence
The convergence of immediate financial savings, rapid installation timelines, and verified emissions reductions has not gone unnoticed by the venture capital community. Newlight recently closed a successful $9 million seed funding round, attracting a diverse syndicate of strategic investors and deep-tech funds.
The funding round was notably bolstered by lomarlabs, the corporate venture arm of Lomar Shipping, which provided not only capital but also the invaluable real-world testing ground for Newlight’s bulk carrier voyage. Additional backing came from BIRD Energy—a joint venture fostering cooperative energy research between the U.S. Department of Energy and the Israel Ministry of Energy—alongside deep-tech specialists Undeterred Capital and CiRi Ventures, and Fusion VC, an accelerator supporting Israeli startups expanding into the United States.
Reflecting on the successful maiden voyage, Haran Cohen Hillel, CEO and co-founder of Newlight, shared his perspective with industry analysts:
"It was amazing. Being onboard and seeing the system operate in real conditions was a completely different experience from anything we had done in the lab… We spent a lot of time monitoring the system, the engine behavior, and the performance, and what impressed us most was how smoothly everything worked. Seeing the system integrate with the vessel, operate reliably, and deliver the results we had been working toward was a huge milestone for us and for the entire Newlight team."
This wave of validation has quickly translated into commercial momentum. Newlight reports that it has already secured binding agreements to install its hydrogen-injection systems across 12 vessels operated by multiple maritime companies, with broader fleet-wide rollouts scheduled for the upcoming year.
Future Outlook: Beyond the Horizon
While Newlight’s immediate strategic focus remains squarely fixed on the maritime shipping industry—where the scale of emissions and the appetite for efficiency gains are immense—the broader technological landscape offers intriguing possibilities.
The global race to decarbonize heavy transport has spawned several competing approaches. Other maritime innovators are exploring alternative fuel injection strategies, such as retrofitting engines to run on ammonia or carbon-neutral methanol. However, these methods often require extensive overhauls of fuel storage tanks, piping, and safety systems due to the toxic or corrosive nature of those chemicals. Newlight argues that its compressed hydrogen setup is inherently leaner, less intrusive, and demands fewer structural modifications to standard marine diesel engines.
Looking further ahead, the founders acknowledge that the underlying energy-optimization technology is not strictly confined to the ocean. Heavy-duty transportation sectors, land-based rail networks, and even power-hungry industrial infrastructure like data centers face similar energy and emissions challenges.
As Hillel notes:
"We’re an energy company, right? So we look at the whole energy situation that is happening around the world, with transportation, and data centers, and we have some investors that even have trains. But we’re gonna try to be focused on shipping right now, and to get on a scale there, and then we can probably expand."
For an industry as traditional and slow-moving as maritime shipping, the emergence of agile startups like Newlight offers a refreshing dose of pragmatism. By fusing military-grade discipline, real-time software intelligence, and a touch of cinematic inspiration, Newlight is demonstrating that the path to a sustainable maritime future doesn’t require scrapping the past—it simply requires making it run smarter.
