“…EROI 3,i includes the same parameters as EROI stnd but also includes the delivery of the energy to the consumer (Atlason and Unnthorsson 2014b). We emphasize that after long-distance transport, oil and coal remain nearly unchanged, while gas (liquefied natural gas (LNG) or pipeline gas) will suffer losses (Lin et al 2010).…”

“…The difference between this method and the previous method is that the total energy used for operation and maintenance is not summed and included with plant construction but is considered to be ongoing throughout the lifetime of the plant (Atlason and Unnthorsson 2014b). The EPT using real-time energy use can be expected to differ slightly from the EPT using lifetime energy use.…”

The studies and development of coal seam gas (CSG) have been conducted for more than 30 years in China, but few of China's CSG projects have achieved large-scale commercial success; faced with the boom of shale gas, some investors are beginning to lose patience and confidence in CSG. China currently faces the following question: Should the government continue to vigorously support the development of the CSG industry? To provide a reference for policy makers and investors, this paper calculates the EROI stnd [a standardized energy return on investment (EROI) method], EROI ide (the maximum theoretical EROI), EROI 3,i (EROI considering the energy investment in transport), and EROI 3,1?e (EROI with environmental inputs) of a single vertical CSG well in the Fanzhuang CSG project in the Qinshui Basin. The energy payback time (EPT) and the greenhouse gas (GHG) emissions of the CSG systems are also calculated. The results show that over a 15-year lifetime, EROI stnd , EROI ide , EROI 3,1 , and EROI 3,1?e are expected to deliver EROIs of approximately 11:1, 20:1, 7:1, and 6:1, respectively. The EPT within different boundaries is no more than 2 years, and the life-cycle GHG emissions are approximately 18.8 million kg CO 2 equivalent. The relatively high EROI and short EPT indicate that the government should take more positive measures to promote the development of the CSG industry.

“…Most studies focus on large-scale hydropower operations [30]. Other studies assume the hydropower plants to last very long on the order of 100e200 years, leading to potential overestimates of the energy returned on energy invested [3,30]. Using information from existing mini-hydropower plants we can estimate the EROI.…”

Energy return on investment (EROI) of mini-hydro and solar PV systems designed for a mini-grid

a b s t r a c tWith dramatic cost declines and performance improvements, both mini-hydropower and solar photovoltaics (PV) now serve as core options to meet the growing demand for electricity in underserved regions worldwide. We compare the net energy return on energy invested (EROI) of mini-hydropower and solar electricity using five existing mini-hydropower installations in northern Thailand with gridconnected solar PV simulations. Both assessments use a life cycle perspective to estimate the EROI. We find that distributed mini-grids with penetrations of solar PV up to 50% of annual generation can exceed the EROI of some fossil-based traditional centralized grid systems. The analysis will help planners and engineers optimize mini-grids for energy payback and utilize local resources in their design. The results suggest higher EROI ratios for mini-hydropower plants than solar PV, though mini-hydropower plants typically yield lower EROI ratios than their large-scale hydropower counterparts.
