Optimizing the Exergetic Efficiency of a Pressurized Water Process for Bio Gas Cleaning
Chemical Engineering Transactions, 2017 A pressurized water process for bio gas cleaning is optimized by means of its exergetic efficiency. The exergy consumption of this process is a suitable measure as it weights electricity and steam consumption and considers the increase of physical and chemical exergy of the treated bio gas stream.

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.
