Abstract We investigate the impacts of a global crisis to trade systems such as Russia-Ukraine war on agricultural emissions, using two emissions accounting approaches: (1) production-based approach, which only accounts for domestic and (2) trade-adjustment considers imports exports when calculating emissions. find that can substantially increase in scenario. The relative degree change, however...

Reliable energy supply becomes increasingly complex in hybrid networks, due to increasing amounts of renewable electricity and more dynamic demand. Accurate modeling integrated gas distribution networks is required quantify operational bottlenecks these increase security supply. In this paper, we propose a network solver model networks. A stochastic method proposed calculate the throughout taki...

Every resource produced by a country should necessity satisfy the needs and demands of its populace before consideration is made for export. This will ensure that sufficient in production allocation resources. While Nigeria regarded internationally as major gas producer world, her local consumption natural limited due to unavailability domestic utilisations fuelled large margins between interna...

The object of research is the energy sector Ukraine, specifically gas supply system national economy. One most problematic places dependence Ukrainian economy on import natural (NG). Ukraine rich in various resources, particular, and associated gas. However, own wells for NG extraction are not enough to industrial enterprises population. Therefore, part necessary imported. In course study, meth...

Abstract: In this paper, we develop a novel electric power supply chain network model with fuel supply markets that captures both the economic network transactions in energy supply markets and the physical network transmission constraints in the electric power network. The theoretical derivation and analysis are done using the theory of variational inequalities. We then apply the model to a spe...

BACKGROUND Calculating the greenhouse gas savings that may be attributed to biofuels is problematic because production systems are inherently complex and methods used to quantify savings are subjective. Differing approaches and interpretations have fuelled a debate about the environmental merit of biofuels, and consequently about the level of policy support that can be justified. This paper est...

Gas-assisted pumps are the most common circulation pumps in remote areas that do not have an electrical power supply. They are basically pneumatic gas driven pumps, specially designed to take advantage of the energy of high-pressure natural gas entrained in the rich (wet) TEG leaving the gas contactor. Additional high-pressure wet production gas is necessary for mechanical advantage, and theref...
