The Dynamic Impact of the Energy Transition on Food Security in Developing Countries

Sustainable Development, EarlyView.
ABSTRACT In the context of persistent food insecurity and the global push for the transition toward clean energy in developing countries, understanding the association between clean energy access and food affordability is increasingly important to inform multisectoral policy interventions. Against this background, this study explores the dynamic impact

Direct primary brown coal liquefaction via non-catalytic and catalytic co-processing with model, waste and petroleum-derived hydrogen donors [PDF]

, 2018
: Direct coal liquefaction (DCL) seems to be a suitable way to convert low rank coals into liquid fuels, especially when problematic wastes are used together with this feedstock. It is also a solution to become energy independent for many countries which

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Preliminary Study on Unit Commitment for Renewable Energy Integration Considering Operation Cost and Life Cycle Assessment

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Comparative analysis of covalent bond cleavage and free radical behavior during the heating process in direct coal liquefaction of Naomaohu and Shangwan coals

Fuel Processing Technology
The cleavage of covalent bonds and the generation of radicals play a crucial role in product distribution during direct coal liquefaction (DCL). This paper systematically investigates the mechanisms of covalent bond cleavage and the behavior of free ...

Relationship of coal characteristics to coal reactivity for direct hydrogenation liquefaction

Fuel Processing Technology, 1987
Abstract Two suites of coals from the U.S. have been liquefied in a batch stirred autoclave reactor under a set of standard conditions. Data from the reactor have permitted both the rate and extent of conversion to be measured. Rate of reaction and extent of conversion of coal have then been used as dependent variables for development of correlations

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...

Towards Sustainable Urbanization and Zero–Carbon Urban Life: A Case Study of BRICS Countries Between 1992 and 2020

Natural Resources Forum, EarlyView.
ABSTRACT Urban factors play a critical role in efforts to reduce greenhouse gas emissions and adapt to climate change. In this regard, this study aims to examine the impact of urbanization and its components (e.g., urban population growth [UPG], population in the largest city [ULC], population in urban agglomerations [UPA] of more than 1 million, and ...
