Innovation is no longer the challenge in shipping. Adoption is.
In the latest episode of Seathrough Efficiency, we sat down with Krishnan Narayanan to discuss the newly announced collaboration between MarineFifty and Njord, and why the industry is entering a new phase focused on scalable, measurable efficiency solutions.
From independent validation and real-world performance measurement to the role of collaboration in accelerating decarbonization, the conversation explores why energy efficiency technologies are becoming one of shipping’s most practical “no-regret” pathways forward.
“What the industry really lacks is a consistent, trusted way to validate performance in the real world, without that, scaling technologies becomes extremely difficult.” – added Krishnan
