Green hydrogen is a fuel capable of promoting sustainable energy development and is gaining attention in the current global energy transition framework. The global shift toward decarbonization has triggered a substantial boost in the hydrogen industry. This study presents an overview of the current status of hydrogen production, regulation of the green hydrogen segment, hydrogen storage, distribution, and transportation, and final use and application. We also critically discuss the viability of adopting green hydrogen in terms of possible economic and environmental impacts as well as the main challenges and opportunities it represents for the Chemical Sciences.

ORGANIC AND INORGANIC BIOMARKERS OF ATMOSPHERIC AEROSOLS FROM MARINE REGIONS. In this study, we overview the recent advancements in knowledge regarding organic and inorganic biomarkers of atmospheric aerosols from coastal zones and open marine areas. It deals with the interaction between the ocean and the atmosphere through their interface, the formation of a seawater microlayer (SML) and the exchange of a myriad of chemical compounds between those environmental compartments. We also discuss how marine aerosols (MAs) are intrinsically related to the global carbon cycle, influence the radiative budget of the Earth, and are related to global climate. At the end, we discuss the trends of new studies on the topic.
