Barriers to Green Technology Adoption in Inland Waterway Transport: A Narrative

This article reviews the challenges affecting the adoption of green technologies in inland waterway transport (IWT).While technologies such as LNG, biofuels, hydrogen, electrification, and emission abatement offer environmental benefits, their implementation faces barriers including high costs, technical limitations, inadequate infrastructure, and fragmented regulations.The study categorizes these challenges through a narrative literature review, emphasizing the need for coordinated policies, financial incentives, and infrastructure investment.It also highlights the role of institutional support and stakeholder engagement in enabling a green transition.Future research should explore the effectiveness of policies, the scalability of technology, and the socio-economic impact on IWT stakeholders.
