The objective of this paper is to propose a decarbonization roadmap for Taiwan achieve net-zero emissions by 2050 analyzing the status fossil and non-fossil energies, screening applicable technologies their effectiveness, then proposing an energy mix future. novelty work lies in process, which considers six, instead one or two, categories: sustainability, security, affordability, reliability, t...

South-Eastern European (SEE) countries are typically keen to maintain the status quo in their energy systems, generally characterized by underinvestment, high coal share and utility affordability needs. Their mixes have historically been determined external factors, currently mainly related decarbonization pressure. This article assesses how EU’s ongoing decarbonization-driven withdrawal from s...

This study internalizes carbon pricing and other regulatory policy tools for decarbonizing the electricity generation mix of Sri Lanka. Carbon Pricing is shifted to supply side as a decision-making tool. We consider $10/tCO2, $20/tCO2, $30/tCO2, $44/tCO2, $130/tCO2, $297/tCO2 potential prices. Other tools, such mandatory renewable energy (RE) development, fuel switching, fossil phasing out, dev...

clean hydrogen is the major energy carrier for power production. the conversion of co to co2 and zero emission during hydrogen energy production causes high capital cost. it is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. in this era, coal gasification is the most promising technology for t...

There are several phenomenons for polluting the environment, especially in coalfields; which coal spontaneous combustion is one of them. The moisture content is one of the intrinsic characteristics of coal, which has an important role in the occurrence of this phenomenon. Therefore, this research predicts the coal spontaneous combustion tendency based on moisture content. The percentage of mois...

In this paper, we use the Global Gas Model to analyze the perspectives and infrastructure needs of the European natural gas market until 2050. Three pathways of natural gas consumption in a future low-carbon energy system in Europe are envisaged: i) a decreasing natural gas consumption, along the results of the PRIMES model for the EMF decarbonization scenarios; ii) a moderate increase of natur...

In addition to summarizing the main thrusts of each paper presented at this Discussion, other urgent issues involving the role (and characterization) of new catalysts for eliminating oxides of nitrogen, for using CO2 liberated from steel mills, for fuel cells and the need for rapid decarbonization of fossil fuels are outlined.This article is part of a discussion meeting issue 'Providing sustain...

One of the most important methods to produce sponge iron is coal based reduction of iron ore. Direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. Volatile materials in coal play an important role in the reduction of iron oxides. In this study, noncoking coal with high volatile materials from Iran and c...
