Geologic Hydrogen Vs Green/Blue Hydrogen Extracting geologic-hydrogen (by serpentinization, where, iron-rich rock from the oceanic crust gets shifted upwards through tectonic processes, and when such rock chemically interacts with water, iron gets released, while water gets reduced to hydrogen through mineralization and chemical oxidation/reduction) being a comparatively low-carbon process, whether the future of green-hydrogen (produced from renewable electricity via electrolysis) and blue-hydrogen (produced via natural gas coupled with carbon capture and storage) – would remain influenced?

Researchers from Lille University of Science and Technology investigated CO2 hydrogenation using #Flowrence system. ? The team varied the catalyst composition by adding halogen promotors to steer the production away from CO, and improve the methanol yield of the CO2 conversion. The reaction of CO2-to-methanol is considered a promising route for decarbonization as it could turn greenhouse emission gas CO2 into a valuable feedstock for basic chemicals. An important intermediate of this process is the platform chemical methanol which, in turn, can be converted into various chemicals. ? The Flowrence 16-reactor system demonstrated its resolving power and speed for obtaining the kinetic reaction data. These were combined with composition characterization of the catalyst to explain the effect of adding specific amounts of halogens on the chemical conversion of CO2 and the suppression of the ?(reverse) Water Gas Shift reaction. ?

This phytomining with agrivoltaics and carbon removal will be so powerful. It's combining several layers of carbon removal at each step. They are using enhanced weathering of minerals to capture carbon and fertilize farmland to then harvest the biomass and metals in the soil through pyrolysis that can supply generators in long duration energy storage. I've been researching plasma and microwave gasification and also flash joule heating to make graphene. The potential for microgrids for advanced manufacturing with flexible interconnection requirements is huge. This could be done on brownfields and land contaminated with #PFAS to remediate the soil while extracting resources and destroying the hazardous materials. https://lnkd.in/gvg_psyT

??Pyrolysis, though a complex phenomenon, essentially involves dehydrogenation and C-C bond rupture in organic radicals. Both of these reactions are endothermic, meaning heat must be supplied to sustain them. At elevated temperatures, hydrocarbons become unstable, decomposing into hydrogen, methane, olefins, and aromatics. To make this heat-intensive process more efficient, one option is to use catalysts such as nickel. These catalysts lower the activation energy required, allowing pyrolysis to occur at lower temperatures or with higher reaction rates. Additionally, catalysts enhance the selectivity of the process towards specific products. However, maintaining high CONVERSION RATE over time is challenging due to carbon deposition on reactor surfaces, which reduces the active sites on the catalysts. The pyrolysis of methane to produce hydrogen, known as turquoise hydrogen, is gaining significant attention. This is evidenced by the growing interest and investment recorded in the International Energy Agency (IEA) database. To achieve net-zero emissions, innovative technologies like microwave-driven methane pyrolysis or thermal plasma pyrolysis are being explored to provide the necessary heat instead of using combustion. The question remains: How successful have these new technologies been? #HydrogenEconomy #Pyrolysis #Catalysis #SustainableEnergy #Innovation #CleanEnergy #NetZero #TurquoiseHydrogen #ProcessEngineering

Hot off the presses in Hydrogen: PhD student Rana Al Homoud work on recovery of stored hydrogen after multiple injection-withdrawal cycles. TLDR: hysteresis can eat up almost half your H2; choose your cushion gas wisely. https://lnkd.in/gJq2MrgE

The third paper of my PhD is out! This found that Iron (III) Chloride was not a suitable catalyst for supercritical water gasification of microalgae, which, while disappointing at first, actually helped discover some interesting phenomena. Check it out if you are interested. https://lnkd.in/ehwpQU3M

The discovery of the role of perovskite is very important since it also offers a way to store hydrogen. Each molecule of ammonia packs three atoms of hydrogen and packing 20 percent of the weight of the molecule. On its own, hydrogen is highly combustible, but ammonia does not combust easily, making it a good medium to store it until needed. #H2 #hydrogen #perovskite

In 2018 I was quite smitten with the idea of using microbes to convert very dirty lignite coal into very clean Natural Gas. A solution for Europe? In light of what happened with Russian gas may be even more interesting. The article is remastered but not editorially changed. https://lnkd.in/deFxBHbJ

?? SPT Editor’s Choice Article: ? #Catalytic dechlorination of carbon tetrachloride to combustible hydrocarbons by Pd-Fe hydroxides through atomic hydrogen attack and direct electron transfer, by Huang et al., from Wuhan University, China; University of Science and Technology of China. ?? Carbon tetrachloride (CT), a common persistent #pollutant in #groundwater, has attracted widespread attention from environmental researchers. The #dechlorination from CT to combustible #hydrocarbons not only represents the removal of contaminants, but also offers the possibility of recovering #carbon #resources from #water. In this work, the coprecipitation of Fe(II) and Pd(II) was used to synthesize Pd-Fe hydroxides for the dechlorination of CT. ?? Key messages: ? Pd-Fe hydroxides catalyst with iron hydroxides and Pd cluster structure is successfully synthesized. ? CT with 26 μM concentration is fast removed within 5 min, and 43.3 % of CH4 and 11.6 % of C2H6 were generated after 110 min. ? Pd(0) sites provide the binding site of CT and generate Hads? to attack carbon-chlorine bonds. ? Pd-Fe hydroxides show high CT removal efficiency in real groundwater. https://lnkd.in/ddrm5DVA Promoted by SPT Social Media Team Chao He Shouliang (Shawn) Yi Luaine Bandounas, Ph.D María Jose Valero Romero Steven Weinman Zong Yang (Savier) Kong Sergio Santoro Alessio Fuoco Harvey HUANG Xiangkun (Elvis) Cao Choe Earn Choong Zhien Zhang Jorge Pereira

#Biomass reburning efficiently controls nitric oxide emissions, with potassium in #biochar playing a crucial role. Research using density functional theory shows potassium lowers energy barriers in NO reduction, enhancing nitrogen generation and influencing biochar’s interaction with carbon monoxide. Further study on these mechanisms is essential. https://lnkd.in/gTT5WWcf
