Exergetic Analysis of Biodiesel Production Routes

DEStech Transactions on Engineering and Technology Research, 2018
Biodiesel is a possible successor to conventional diesel. Several methods, with the most varied raw materials and different routes, are available in the literature, directed to the production of biodiesel. In this way, the objective of this work was to evaluate the energetic conversion process from two routes: via basic homogeneous catalysis and via ...

Solar Dish Collectors for Hydrogen Production: A Review

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Solar‐driven hydrogen production stands at the nexus of the global transition toward net‐zero energy systems. This review surveys the role of solar dish collectors (SDCs) as high‐flux concentrators that can directly or indirectly split water, positioning hydrogen as a long‐duration, carbon‐free energy carrier.
