Next-Generation Bioenergy: Challenges for the Regulatory Environment in the Maritime Industry

Abstract

This article explores the changing landscape of next-generation bioenergy technologies and their relevance to the maritime sector amidst increasing global decarbonization efforts. It specifically highlights microalgae-based fuels, residual biomass, and hybrid biochemical-thermochemical systems, forming a varied platform for low-carbon energy. Through comparative analysis of technology, environment, and regulation, the study pinpoints key hurdles for large-scale use – such as high costs, infrastructure challenges, and regulatory inconsistencies. Attention is given to current gaps in the IMO framework, which hinder the recognition and adoption of biofuels despite their potential to significantly reduce emissions from production to use. The article emphasizes that uniform global standards, port upgrades, and support for innovative solutions like genetically optimized microalgae, bioelectrochemical systems, and blockchain tracking are crucial to advancing toward climate-neutral maritime operations.
