Newlight's hydrogen-injection retrofit cuts ship fuel 24% on an 8,500-mile voyage
Bay Area startup Newlight retrofits cargo ships with millisecond-timed hydrogen injection; first voyage cut fuel 24% and CO2 28%, then a $9M seed.
Newlight
What the business is
Newlight sells a retrofit that injects compressed hydrogen into cargo-ship diesel engines at millisecond-optimized moments, cutting fuel consumption and CO2 emissions by more than 20% without replacing the engine or dry-docking the vessel.
Starting capital：$9M seed (2026)
How it started
Co-founders Evyatar Cohen and Haran Cohen Hillel, both veterans of the Israeli Navy, spent years around marine engines before building Newlight in the San Francisco Bay Area. Their system constantly monitors exhaust temperature, combustion pressure, and air intake pressure, and adjusts hydrogen flow with millisecond precision every time a piston moves — not to add power, but to let the engine cut its diesel flow.
What happened
Newlight completed its first long-range commercial voyage in 2026: a month-long, 8,500-nautical-mile trip from Singapore to Ghana on a 650-foot Lomar Shipping bulk carrier, reporting a 24% reduction in fuel consumption and 28% lower CO2 emissions, with annual savings of up to $500,000 per vessel. That performance helped close a $9 million seed round from lomarlabs, BIRD Energy, Undeterred Capital, CiRi Ventures, and Fusion VC, and the company says it has signed agreements to install the system on 12 vessels with broader fleet rollouts planned next year.
How it ended up
Seed-funded and early-commercial: first voyage validated, 12-vessel agreements signed, and fleet rollouts planned for 2027; the founders say they will stay focused on shipping before expanding to trains or data centers.
Background
Newlight is a San Francisco Bay Area startup selling a hydrogen-injection retrofit for cargo-ship diesel engines. The system continuously monitors exhaust temperature, combustion pressure, and air intake pressure, then injects compressed hydrogen with millisecond precision as pistons move — not to add power, but to let the engine burn less diesel, cutting fuel use and CO2 by more than 20% and saving some vessels up to $500,000 a year.
The startup says the system installs in less than two weeks without dry-docking the ship. Its first long-range commercial test was a month-long, 8,500-nautical-mile voyage from Singapore to Ghana on a 650-foot Lomar Shipping bulk carrier, where it reported a 24% reduction in fuel consumption and 28% lower CO2 emissions.
Co-founders Evyatar Cohen and Haran Cohen Hillel are Israeli Navy veterans who spent years around marine engines. Their results and pitch helped close a $9 million seed round including lomarlabs (Lomar Shipping's venture arm), BIRD Energy, deep-tech funds Undeterred Capital and CiRi Ventures, and Fusion VC, and the company has signed agreements to install the system on 12 vessels.
The founders describe Newlight as an energy company and see applications beyond ships — some investors even have trains — but say they will stay focused on shipping, scale there, and only then consider expanding.
What has to be true
- The global cargo fleet is huge, diesel-powered, and expensive to replace; retrofitting existing engines is far cheaper and faster than waiting for new-fuel vessels.
- A two-week installation with no dry dock removes the downtime cost that kills most retrofit products.
- Hydrogen as a combustion enhancer needs none of the engine conversion that ammonia or methanol approaches require.
- Measured results on a real commercial voyage — 24% fuel and 28% CO2 cuts — turn a climate pitch into a fuel-cost pitch that shipowners actually pay for.
What can be applied
Retrofit beats replacement when the installed base is huge and downtime is costly: Newlight sells a two-week add-on to engines ships already have, betting efficiency wins adoption first.
Aftermath
As of September 2026 Newlight has completed its first commercial voyage, reported 24% lower fuel consumption and 28% lower CO2 on an 8,500-nautical-mile trip, and closed a $9 million seed round backed by lomarlabs and BIRD Energy among others. It has signed agreements for 12 vessels and plans broader fleet rollouts next year. The company says it will stay focused on shipping before considering trains or data centers, and the bet that a lightweight retrofit can win adoption before a maritime fuel revolution remains unproven at fleet scale.
