Developing visible-to-near-infrared light-harvesting porphyrin photosensitizers is very important for efficient photocatalytic hydrogen evolution (PHE) since most of the tetra-meso-substituted porphyrins …Hydrogen production. To produce hydrogen, it must be separated from the other elements in the molecules where it occurs. Hydrogen can be produced from many …On Tuesday, December 27, the Kansas-based HARVEST Hydrogen Hub was officially notified by United States Department of Energy (DOE) that it is “encouraged” to pursue a full application for the Regional Clean H2 Hubs program.

The HARVEST Hydrogen Hub Coalition is an alliance of public and private entities in Kansas — including Black & Veatch, Evergy, NextEra Energy and Enel Green Power, to name a few — that have a strong interest in the development of a productive hydrogen-based energy sector that supports a range of economic activity and acts as a hub for the ...Researchers at Rice University have developed a groundbreaking method to extract high-yield hydrogen from mixed waste plastics, without the need for sorting by type or washing. This pioneering approach also yields high-value graphene, opening up new possibilities for sustainable and cost-effective hydrogen production.To estimate the light-harvesting ability of the P-gCN/PMA x samples, their activities have been evaluated through photocatalytic tests for hydrogen production (Fig. S16†). Hence, the intrinsic photocatalytic activities of the as-prepared samples were evaluated by monitoring the H 2 evolution reaction (HER) via the water-splitting reaction under visible …The U.S. Department of Energy launched the Energy Earthshots Initiative in June 2021 with the Hydrogen Shot, which seeks to reduce the cost of clean hydrogen by 80% to $1 per 1 kg in 1 decade ("1 1 1").

The concept of an all-gas-phase photoelectrochemical (PEC) cell producing hydrogen gas from volatile organic contaminated gas and light is presented. Without applying any external bias, organic contaminants are degraded and hydrogen gas is produced in separate electrode compartments. The system work …Improved atmospheric water harvesting through the postfunctionalization of hydrazine-linked covalent organic frameworks toward mixed hydrazine-hydrazide frameworks. ... The high oxygen content of ep-POPs offer efficient hydrogen-bonding sites for water mols., thus leading to high water-uptake capacities up to 39.2-42.4 wt % under …

Impurities could make the liquid oxygen and liquid hydrogen fuel unusable—or worse, unstable and explosive. Water harvesting on the moon will have a high failure rate for years, Metzger predicts.McCormick. Sustainability. Northwestern University researchers have developed a highly effective, environmentally friendly method for converting ammonia into hydrogen. Outlined in a recent publication in the journal Joule, the new technique is a major step forward for enabling a zero-pollution, hydrogen-fueled economy.
