Navigating the Efficiency Wave: The 2nd Ship Energy Efficiency Summit 2025
As global shipping accelerates its transition toward net-zero emissions, improving vessel energy efficiency has become one of the most urgent and achievable pathways to cleaner maritime operations. The 2nd Ship Energy Efficiency Summit, taking place on 26–27 November 2025 in Athens, Greece, brings together shipowners, operators, regulators, technology providers and financial institutions to address the challenges and opportunities shaping the future of sustainable shipping.
Why This Summit Matters
With the IMO’s 2030 and 2050 decarbonisation goals rapidly approaching, the industry faces increasing pressure to tighten energy-efficiency measures across fleets. The Summit provides a valuable platform for exploring practical solutions that can deliver real and immediate impact—from propulsion upgrades and advanced hull design to digital optimisation tools and next-generation fuels.
The event focuses on actionable improvements, offering a blend of high-level policy discussion and hands-on technical insight. For anyone involved in ship management, engineering or sustainability strategy, it promises a concentrated overview of the technologies and operational practices that will shape commercial shipping in the decade ahead.
Key Themes to Watch
The 2025 agenda incorporates a broad spectrum of energy-efficiency topics, including:
-
Future marine fuels such as hydrogen, ammonia, methanol and advanced biofuels, plus the bunkering and infrastructure needed to support them.
-
Hybrid and electric propulsion systems, including battery-assisted operations and retrofitting pathways for existing fleets.
-
Onboard carbon-capture concepts, heat-recovery systems and solutions for optimising engine load and voyage performance.
-
Hull, propeller and coating innovations that deliver measurable efficiency gains.
-
Financing mechanisms that help shipowners invest in greener technologies and reduce transition risk.
-
Regulatory compliance, emissions measurement and data-driven reporting frameworks that underpin the industry’s decarbonisation journey.
Why This Matters
Energy efficiency is one of the fastest ways to reduce greenhouse-gas emissions, fuel consumption and operational impact on marine ecosystems.
Coverage of this event will allow Cleaner Seas to:
-
Highlight emerging technologies and solutions that directly affect ocean health.
-
Provide decision-makers with insights into the practical steps shipping companies are taking.
-
Support industry awareness of environmental performance, efficiency metrics and cleaner operations.
-
Strengthen dialogue between innovators, regulators, ports and shipowners committed to reducing their environmental footprint.
