Abstract

This systematic literature review examines the application of Waste Heat Recovery (WHR) technologies in boiler systems to improve thermal efficiency and reduce CO₂ emissions. Using the PRISMA 2020 framework, 20 relevant studies published between 2010 and 2025 were selected through predefined eligibility and quality criteria. A thematic analysis was conducted to synthesize methodological approaches, performance outcomes, and implementation challenges across the included studies. The findings indicate that WHR integration can enhance thermal efficiency by up to 20.3%, provide fuel savings of 17.9%, and reduce CO₂ emissions by approximately 180 kg/MWh. Heat Recovery Steam Generators (HRSG) and Organic Rankine Cycle (ORC) systems demonstrate the highest performance levels, although their adoption is often constrained by higher capital costs and engineering complexity. The review also highlights gaps in policy incentives and regulatory support, which remain significant barriers to large-scale deployment. Overall, WHR technologies present a strategic pathway for improving industrial energy efficiency and advancing decarbonization efforts through a synergistic interplay of technological innovation, economic feasibility, and supportive policy frameworks.

Abstract

The growing demand for clean energy has accelerated interest in Floating Offshore Wind Turbines (FOWTs), which enable efficient wind energy harvesting in deep-water regions. This study conducts a systematic literature review across four major databases, Scopus, ScienceDirect, SpringerLink, and Google Scholar, to evaluate the energy efficiency, carbon emission reduction potential, and economic feasibility of FOWT systems. The findings indicate that combined configurations, such as Spar–TLP and multi-turbine platforms, provide the highest energy conversion performance and structural stability, contributing to up to 17% in carbon emission reduction. Economically, several studies report competitive Levelized Cost of Energy (LCOE) and relatively short payback periods. This research strengthens the understanding of FOWT performance by integrating global evidence into the context of marine energy sustainability. However, methodological limitations arise from data variability across studies and the dominance of simulation-based analyses. Further research is required to optimize mooring systems and adapt FOWT designs to tropical and archipelagic environments, such as those found in Indonesia.
