WHATS THE PROBLEM?
Shipping contributes to 3% of global emissions annually, and with cargo ships typically having a lifespan of 25-30 years, the industry faces significant challenges in meeting new emission regulations.
These regulations require a 40% reduction in carbon intensity by 2030.
While hydrogen-powered ships are still on the horizon, retrofitting existing diesel ships offers a promising path to decarbonisation.
This week’s company, GT Green Technologies, has created an innovative solution to make shipping more sustainable👇


Solution in a sentence: Installing AirWing wind propulsion technology on vessels to save fuel, reduce emissions, and cut costs while meeting EU ETS targets.
Key Features:
Retrofittable or suitable for new ships.
Compact design minimises cargo operation impact.
Modular and transportable for rapid scalability.
Fuel savings with industry-leading lift and thrust coefficients (10-30% reduction).
3-4 year payback period.

Company breakdown:
Industry: Marine
Headquarters: Liverpool, England
Year Founded: 2021
Employee Count: 9
Investors: OnePlanetCapital, Carisbrooke Shipping, John Good Group plc
Previously Raised: £1.35 million seed round + £3.7 million grant
Early Traction: January 2024, GT Green Technologies received a £3.7 million grant from the UK Department of Transport to manufacture, install and test the first AirWing device on a vessel.


Due Diligence
WHAT WE LIKE
Market size: Over 20,000 ships subject to emissions regulations can benefit from retrofittable AirWing technology. Today, there have only been 35 installations. Total addressable market expected to be greater than $10bn by 2030.
Scalable design: AirWing can be shipped globally in containers.
Cost savings: Fuel savings pay for the technology within 3 to 4 years.
POTENTIAL RISKS
Cost Efficiency vs. Carbon Credits: As carbon markets evolve, credit prices may decrease. However, investing in carbon credits remains a cost-efficient way to meet emission reduction targets.
Competitive Market: GT Green Technologies lacks a first-mover advantage and hasn’t compared efficiency data with competitors. The true savings of the AirWing will become clear after its initial installation later this year.
Retrofit Challenges: Retrofitting wind propulsion technology (WPT) can impact engine health due to legacy vessels designed for consistent RPM. Structural adjustments may also be necessary.
