Abstract

Steam power plants are among the primary sources of electricity generation; however, they face significant challenges in terms of energy efficiency and environmental impact due to their high consumption of coal. Innovative strategies are required to reduce emissions and improve system efficiency. One potential approach is the reutilization of condenser cooling water to drive a hydropower turbine before being discharged into the sea. By harnessing the head and flow rate of this water, the kinetic energy from the waste stream can be converted into additional electricity. This study examines a process engineering approach to integrating a hydropower generation system with a steam power plant, encompassing technical analysis, energy efficiency, as well as economic and environmental impacts. Simulation results indicate that the system is capable of generating between 14.2 and 49.5 kW of power, depending on operating conditions and water availability. The electricity produced can be utilized for internal Steam power plant needs, such as cooling pumps and lighting, thereby reducing dependence on coal combustion. This strategy not only improves energy efficiency and reduces operational costs but also supports environmental conservation and the long-term sustainability of power plant operations.

Abstract

Building energy management systems (BEMS) are essential for enhancing energy efficiency and sustainability in buildings. This literature review analyzes BEMS research trends from 1982 to 2024, utilizing bibliometric analysis based on a dataset from Scopus. The study identifies key developments that influence all publications and emerging research topics in the field. While BEMS offers significant potential for real-time energy monitoring and control, challenges remain, including the need for standard protocols, improved cybersecurity, and cost-effective solutions for small buildings. This research highlights the importance of addressing these challenges to foster wider adoption of BEMS technology and contribute to a sustainable energy future. The findings aim to guide future research directions and enhance the implementation of BEMS in various building types.

Abstract

The rising demand for sustainable offshore oil and gas operations has accelerated the need for efficient, low-emission energy systems. Conventional fossil fuel-based systems significantly contribute to greenhouse gas emissions, underscoring the need for innovative alternatives. This study proposes and evaluates a hybrid energy system that integrates thermoelectric generators (TEGs) and photovoltaic (PV) panels to enhance energy efficiency, reduce emissions, and improve the sustainability of offshore operations. The system design utilizes both manual calculations and simulations, employing PVsyst software, to evaluate performance metrics. Results show that the TEG + PV hybrid system improves energy efficiency and reduces carbon emissions by approximately 40% compared to traditional fossil fuel systems. TEGs utilize waste heat from natural gas combustion, while PV panels capture solar energy, creating a synergistic effect that significantly reduces environmental impact. This hybrid configuration also aligns with emission reduction regulations in the oil and gas sector. Beyond environmental benefits, the hybrid system offers economic advantages. Fuel consumption and operational costs are notably reduced, with total savings in capital and operational expenditures (CAPEX and OPEX) reaching IDR 2.53 billion. These savings demonstrate the system’s financial viability and support its adoption in real-world offshore applications. In conclusion, the integration of TEG and PV technologies into a hybrid energy system offers a practical and sustainable solution for offshore oil and gas operations. The system achieves emission reduction targets, enhances operational efficiency, and delivers cost savings, thereby supporting the industry's transition toward more environmentally responsible energy practices.

Abstract

This study evaluates the impact of an earthquake on a mini-hydropower plant (MHP) and formulates a disaster management strategy to enhance the operational resilience of MHPs against seismic events. Data was collected through interviews with relevant stakeholders, direct observations, and analysis of pertinent documents. The findings indicate that the 2018 Lombok earthquake caused severe damage to the catchment area, triggering increased sedimentation that disrupted the MHPs operation, resulting in decreased electricity production and escalated operational costs. Mitigation measures were implemented and proved effective in reducing debris-related downtime and improving electricity generation. Thes findings are expected to provide guidance for MHP operators in mitigating the negative impacts of earthquakes and similar disasters on plant operations.
