The maritime industry in Nigeria is critical to the nation’s economy but remains a significant contributor to greenhouse gas (GHG) emissions due to aging fleets, reliance on heavy fuel oil (HFO), and limited adoption of green technologies. This review evaluates cost-effective green ship
technologies identified in the literature—hull optimization, renewable energy integration, alternative fuels, and waste heat recovery systems—assessing their potential applicability and economic viability considering the challenges and opportunities in Nigeria. Synthesizing findings
from stakeholder reports, comparative analyses of international case studies, and technical literature, this review suggests these technologies could potentially reduce fuel consumption by up to 30% and cut emissions by 5–30%, offering cost savings for shipowners. A synthesis of costbenefit
data indicates potential payback periods ranging from 1 to 8 years, varying significantly by technology and implementation context, highlighting economic feasibility under certain conditions but also significant investment needs. The paper concludes by summarizing the
reviewed solutions and offering actionable policy recommendations derived from best practices to enhance capacity building, incentivize investments, and modernize Nigeria’s maritime infrastructure, paving the way for a more sustainable and competitive industry.
