The limited intra-hour variability of globally available hourly renewable energy system data leads to inaccuracies in the modeling of renewable energy systems. This work, therefore, presents a methodology to increase the temporal resolution of the global horizontal irradiance from one hour to one minute using non-dimensional irradiance and parameters matching for arbitrary locations. [...]

Long-term development of mobility demand cannot be evaluated without also accounting for the simultaneous evolution of the social, political, and economic framework. This is of special importance in regions that will undergo far-reaching structural change processes on their way to carbon neutrality. [...]

The German mining region “Rheinisches Revier” is undergoing significant economic and social transformations. This transformation is driven by Germany's effort to achieve climate neutrality by 2045 through the phase-out of lignite. [...]

Based on the Green Deal, the European Commission is committed to reducing net greenhouse gas emissions and achieving greenhouse gas neutrality by 2050. Germany aims to achieve this goal by 2045. [...]

Europe’s strategy to decarbonize the energy sector in accordance with climate mitigation goals requires a high penetration of variable renewable energy sources, particularly offshore wind energy. As capacity is projected to expand significantly over the coming decades, the kinetic energy depletion from the atmosphere by large-scale wind farms cannot be ignored. [...]

Atmospheric gravity waves vary hugely in scale; with horizontal wavelengths ranging from a few to thousands of km. Typically, gravity waves are smaller than model grid-size and as a result, their effects are parametrised instead of being explicitly resolved. [...]

Techno-economic System Analysis of Alternative Power Trains for Non-road Mobile Machinery Serhiy Kapustyan,a Thomas Grube,a Jochen Linssen,a and Detlef Stolten a,baForschungszentrum Jülich GmbH, Institute of Energy and Climate Research – Jülich Systems Analysis (ICE-2) , 52425 Jülich, GermanybRWTH Aachen University, Chair for Fuel Cells, Faculty of Mechanical Engineering, 52062 Aachen, GermanyAbstractThis study provides a comparative techno-economic systems analysis of different powertrain and fuel options with associated infrastructure for non-road mobile machinery and compares them with conventional diesel systems.First, the comprehensive framework required for a complete techno-economic analysis of different powertrain options for non-road mobile machinery is presented. The model includes a load profile generator designed for various machines used in sectors such as construction and agriculture. [...]
