Energy and Exergy Analysis of an Integrated SOFC–LiBr/H2O Absorption Trigeneration System: Parametric Effects on Power, Heat, and Cooling Performance

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT This paper presents a comprehensive thermodynamic assessment of a trigeneration system integrating a solid oxide fuel cell (SOFC) with a lithium bromide–water (LiBr–H2O) single‐effect absorption chiller. A systematic parametric analysis is conducted to investigate the influence of key SOFC operating parameters including current density, fuel ...

Capacity Optimization of an Hydrogen–Ammonia Hybrid Storage System With Concentrated Photovoltaic–Photothermal Power Generation

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
As a renewable energy carrier, hydrogen offers a promising solution to mitigate the intermittency of renewable energy and improve energy utilization efficiency, but it faces cost challenges in seasonal energy storage. To address this, this study proposes a hydrogen–ammonia hybrid storage system integrated with a concentrated photovoltaic photothermal ...

Cross‐System Comparative Techno‐Economic and Environmental Evaluation of MCFC Integration in Power and Biogas Upgrading Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Achieving net‐zero or carbon‐negative energy systems requires technologies capable of generating power while capturing or utilising CO2 without significant efficiency losses. Molten carbonate fuel cells (MCFCs) offer such potential, yet their techno‐economic competitiveness across different energy systems remains insufficiently quantified.

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

On the Equivalence Between Null Space and Orthogonal Space in Latent Variable Regression Modeling

Journal of Chemometrics, Volume 39, Issue 8, August 2025.
ABSTRACT The concepts of null space and orthogonal space have been developed in independent contexts and with different purposes: the former arises in the inversion of partial least‐squares (PLS) regression models, and the latter in orthogonal PLS (O‐PLS) modeling.
