Current State and New Trends in Green Hydrogen Energy

Dear Colleagues,

Green hydrogen is one of the most promising energy suppliers to outcompete conventional energy production based on fossil sources, decreasing greenhouse gas emissions and supporting a circular economy. Typical processes and technologies for hydrogen production, transportation and storage result in CO₂ emissions and environmental impact. Green hydrogen produced with renewable fuel sources can contribute to the green energy transition. This Topical Collection will collect feature papers aimed at critically reviewing the current state and discussing the prospects of carbon-neutral technologies for hydrogen production and use.

Topics of interest for publication include, but are not limited to, the following:

• Green hydrogen production;
• Green hydrogen separation and purification;
• Green hydrogen transportation;
• Green hydrogen storage;
• Green hydrogen conversion and utilization;
• Green hydrogen economy and environmental impact.
