The rapid advancement of modern technology has led to a steep rise in global energy demand, posing serious challenges related to climate change and the geopolitical complexities of energy sourcing. In this context, modulators and optical amplifiers have be ...

An infinite-horizon optimal control paradigm is proposed to model the global energy transition to zero-net emissions when carbon dioxide removal (CDR) and electric fuel (E-Fuel) technologies become available. Infinite-horizon optimal trajectories for conve ...

Artificial photosynthesis system to realize Solar overall water splitting has been regarded as sustainable and renewable solution for energy and environmental issues. While artificial photosynthesis system (efficiency of 12.4%) greatly exceeds efficiency o ...

This article offers a view of the prospects of nuclear fusion as a sustainable energy source, with a focus on magnetic confinement fusion and tokamaks. It highlights the key theme of integration and presents the EUROfusion programme as a model for coordina ...

Cutting plane methods are a fundamental approach for solving integer linear programs (ILPs). In each iteration of such methods, additional linear constraints (cuts) are introduced to the constraint set with the aim of excluding the previous fractional opti ...

This study proposes a multi-objective optimization methodology for planning multi-energy complementary distributed energy systems considering process synergy and thermal integration. The process integration tech-nique is integrated into the Energy Hub mode ...

Achieving climate neutrality will require clean alternatives to entirely replace fossil technologies in most economic sectors. However, standard Computable General Equilibrium (CGE) frameworks, which are widely used to analyse climate policies and rely on ...

This study presents an inter-comparison of three structurally different electricity system models (EXPANSE, Nexus-e, and OREES) with sub-national spatial resolution in Switzerland in 2035. We analyze technology and regional implications of three targets fo ...

The traditional sequential design of building elements, where every element performs only one dedicated function, carries significant embodied energy. Thus, modular pre-fabricated load-bearing elements could overcome the disadvantages of the current carbon ...

Due to the integration of renewable-based Distributed Generation Units (DGUs), Energy Storage Systems (ESSs) and electric car charging stations, more and more power electronic converters are connected to the grid. In grids with a high penetration rate of t ...

District Energy Systems (DES) have been widely recognized as crucial components for successful national energy transitions towards meeting 2050 greenhouse gas emissions' reduction targets. While District Heating Network (DHN) still has a role to play in th ...

Carpooling is an efficient measure to fight car ownership and reduce vehicle kilometres travelled. By individuals sharing their commutes, vehicle occupancy increases and congestion is reduced. We develop a dynamic ADL (Arnott, de Palma, Lindsey)-Vickrey ap ...

Choice-based optimization problems are the family of optimization problems that incorporate the stochasticity of individual preferences according to discrete choice models to make planning decisions. This integration brings non-convexity and nonlinearity t ...

This work presents solutions for the holistic utilization of lignocellulosic biomass based on the "lignin first " concept. Biomass is fractionated by employing gamma-Valerolactone (GVL) and formaldehyde solvents to effectively extract and protect the ligni ...
