“…The electricity price to natural gas price ratio obtained is 5.68, which clearly shows a remarkably low price of natural gas, despite the fact that electricity tariff in Monterrey is lower than those in other regions in Mexico. This price ratio is 16.4% greater than the highest one (i.e., 4.88), which was reported by [28] (Italy). Figure 7 plots the PBT and annual savings of the hybrid plant as a function of the energetics price ratio C e /C f .…”

Energetic and Economic Analyses of an LCPV/T Solar Hybrid Plant for a Sports Center Building in Mexico

This study presents a techno-economic performance evaluation of a hybrid low-concentrating photovoltaic/thermal (LCPV/T) plant, which operates in a student sports and wellness center building situated at a university campus in Mexico. The solar plant comprises 144 LCPV/T collectors based on a hybridized version of a local parabolic trough technology. Dynamic thermal and electrical performance analyses were performed in the TRNSYS simulation studio. The results showed that the solar field could cover up to 72% of the hot water demand of the building during the summer season and 24% during the winter season. The hybrid system could annually save 7185 USD, accounting for heat (natural gas boiler) and electricity generation. However, the payback time was of 19.23 years, which was mainly attributed to a reduced natural gas price in Monterrey, Mexico. A new approach to evaluating the equivalent levelized cost of heat (LCOHeq), is proposed. This results in an LCOHeq of 0.065 USD/kWh, which is nearly equivalent to the LCOH of a natural gas-fired boiler (0.067 USD/kWh). Finally, the hybrid plant could achieve a specific CO2e emission reduction of 77.87 kg CO2e per square meter of the required installation area.

“…After applying the combined system in Chengdu City, Sichuan Province, China, the system recovered approximately 13.5% of the ventilation energy and generated approximately 2074 kWh of energy per year [ 104 ]. Due to the large amount of electric energy, steam and hot water used in dairy processing, Wang et al [ 105 ] proposed a solar cogeneration system based on parabolic trough hybrid photovoltaic (PVT) collector for use in dairy farms. The system provides 14% electric energy, 52% steam and 40% hot water for dairy processing.…”

Petroleum agriculture, characterized by mechanization and chemistry, is developing rapidly in China. However, petroleum agriculture has not only brought food safety problems, but also caused great obstacles to the sustainable development of society. In view of the disadvantages of oil agriculture, we provide an upgrading plan for energy systems in agriculture. This work can help reduce carbon emissions and improve food security. We introduce the most advanced technologies in Chinese agricultural development and the technical scope includes new agricultural energy power generation, agricultural energy use and the safe operation of agricultural energy systems. We describe the detailed data of agricultural bioenvironmental and energy engineering to clarify the level of agricultural energy efficiency in China. The overall conclusion of this paper is that the deep integration of agriculture and energy internet has become the development trend of agricultural energy systems.

The Photovoltaic/thermal (PV/T) system combines the conventional PV panel with solar collector into one integrated system, which could achieve the function of generating power and providing thermal energy at the same time. Recently, it has become the most promising solar system for building applications. Most of the PV/T systems use water as the coolant, which could cause freezing problem in winter. To overcome this problem, the heat pipe PV/T system is developed to provide electrical and thermal energy stably without the seasonal barrier.Although some published review works have involved this type of PV/T system, they just stated a simple introduction on it, acting as a small part of their works. This paper focuses on the heat pipe PV/T system independently and provides a comprehensive and in-depth analysis of its performance. Firstly, the structure and operational principles of the heat pipe PV/T module and system are introduced concisely. Then the features and performance of different types of heat pipe PV/T systems, i.e., integral heat pipe, loop heat pipe, and pulsating heat pipe PV/T system, are presented and analyzed. This is followed by the review on the performance of the systems which combine heat pipe PV/T module and other devices. Finally, the research gaps in this field are identified, and some future research trends and directions are recommended.
