“…55 Solid biomass relies on the same inflexible steam Rankine power cycle as coal; therefore, it is not included in this study. Biogas resource availability is limited 56 and costs are highly uncertain; 57 therefore, we exclude it from the primary analysis in this paper but include it as a sensitivity parameter for traditional NG-CC plants in the supplemental experimental procedures. Ethanol in gas turbines has been demonstrated at an 87-MW scale with modifications and installation of other peripheral equipment, 58 and only minor modifications would be required for higher efficiency combined-cycle operation.…”

Solar and wind energy are being rapidly integrated into electricity grids around the world. As renewables penetration increases beyond 80%, electricity grids will require long-duration energy storage or flexible, low-carbon electricity generation to meet demand and help keep electricity prices low. Here, we evaluate the costs of applicable technologies based on current technology status and future projections. We show which technologies have the lowest costs and identify opportunities for each to help decarbonize the electricity grid.

“…Within the existing studies on the implementation of RES, our research relates to those that are devoted to the assessment of renewable energy sources potential (both in terms of availability of different sources and appropriateness of their implementation) [13,19,[95][96][97][98][99][100][101][102][103][104][105][106][107][108]. This group of studies may be considered to be a first step that allows understanding whether it is worth considering the implementation of RES at a given territory.…”

The paper is devoted to the assessment of the prospects of implementing clean energy sources in Russia, where the current energy policy goal is to increase the role of renewable and clean energy sources. The research is based on data from the Krasnoyarsk Region as one of the largest territories but also as a representative model of Russia. The aim of the study is to identify where and which renewable energy source (solar, wind, hydro and nuclear) has the highest potential. The novelty of our research lies in its holistic nature: authors consider both geographical and technical potential for renewable energy sources development as well as prospective demand for such resources, while previous research is mostly focused on specific aspects of renewable energy development. We also consider the level of air pollution as an important factor for the development of renewable energy sources. The results of the study show that there is a strong potential for clean energy sources in the Krasnoyarsk Region. The resulting matrix identifies the potential of energy sources across all the municipal entities and also indicates whether the source of energy is primary or supplemental and where several sources may be implemented in cooperation.

“…Biogas can be produced from various different waste resources before being upgraded to RNG. Some of these options include landfills, wastewater treatment plants, livestock or fats, oils, and greases through anaerobic digestion [7]. There are limited livestock operations in New Jersey, but in other areas this has proven to be an efficient RNG producer.…”

“…This is an opportunity to create RNG from methane produced in landfills and WWTPs. Over the past few years, RNG production from landfills, livestock, and WWTPs have proven environmentally beneficial and economically feasible for California, specifically utilizing state specific incentives [7,8]. The use of RNG as a low-carbon vehicle produced from various waste sources in the United States has also been studied and has been shown to be feasible as well, specifically utilizing organic waste from landfills and manure from farms [9].…”

The Feasibility of Renewable Natural Gas in New Jersey

With traditional natural gas being one of the top options for heating in the United States and the present threat of climate change, there is a demand for an alternative clean fuel source. A Renewable Natural Gas Implementation Decision-Making Conceptual Model was created to provide a framework for considering the feasibility of renewable natural gas (RNG) projects and applied to New Jersey, specifically investigating landfills and wastewater treatment plants (WWTPs). Data from the US EPA’s Landfill Methane Outreach Program and New Jersey’s Department of Environmental Protection Sewage Sludge databases were used to identify seven landfills and 22 WWTPs as possible locations for RNG projects. Landfills were found to have a higher potential for producing RNG, on average potentially producing enough RNG to heat 12,792 homes per year versus 1227 for the average WWTP. Additionally, landfills, while having higher capital expenses, have lower projected payback periods, averaging 5.19 years compared to WWTP’s 11.78 years. WWTPs, however, generally are located closer to existing natural gas pipelines than landfills and when they produce more than 362 million standard cubic feet per year (MMSCFY) of biogas are financially feasible. RNG projects at Monmouth County Reclamation Center, Ocean County Landfill, and Passaic Valley Sewerage Commission WWTP show the greatest potential. Greenhouse gas emission reductions from RNG projects at these facilities utilizing all available biogas would be 1.628 million metric tons CO2 equivalence per year, synonymous to removing over 351,000 passenger vehicles from the road each year. In addition, expanding federal and state incentives to encompass RNG as a heating fuel is necessary to reduce financial barriers to RNG projects throughout the US. Overall, this paper supports the hypothesized conceptual model in examining the feasibility of RNG projects through examples from New Jersey and confirms the potential for RNG production utilizing existing waste streams.
