Scaling adoption of energy efficiency technologies
Project FEET: Pilot fund for energy efficiency technologies
Objective
Develop and launch a first-of-a-kind pay-as-you-save fund for energy efficiency technologies (EETs)
Project scope
• Catalyse private capital from a pool of investors having different risk appetites
• Invest in a diverse set of EET retrofit projects
• Demonstrate viability of pay-as-you-save by pegging part of returns to quantified and verified fuel savings
• Showcase scalability of such a fund
Highlights
• Fund for Energy Efficiency Technologies (FEET) provides up to 100% upfront financing for retrofits and introduces a pay-as-you-save repayment mechanism linked directly to verified fuel and regulatory savings
• By offering unsecured leases on retrofits, FEET decouples retrofit financing from vessel mortgages
• Through a blended financing structure and a diversified project portfolio, FEET balances financial risk while keeping financing costs competitive

Press release: World’s first vessel retrofit fund using a pay-as-you-save repayment mechanism closes at USD 35M
By switching the focus of performance sharing to financiers and linking payments to real-world results, PAYS creates an investable structure for energy-efficiency retrofits that previously lacked suitable financing.
The Fund for Energy Efficiency Technologies (FEET) provides the following levels of financing:
100% Upfront Financing: The fund covers up to 100% of the upfront costs for vessel retrofits, specifically including the equipment, installation, and sensorisation.
Current fund size: As of its initial closing in November 2025, the fund has secured total commitments of up to USD 35 million.
Future scaling: There is a strategic target to scale the fund to USD 500 million by 2030, which would be capable of supporting approximately 200 ships.
