The critical role of hydrogen in the development of new biofuels
peer reviewed / Synthetic fuels (called synfuels) will play a major role in ensuring a gradual environmental transition in the transport sector. Our analyses have shown that the deployment of these alternative fuels is intrinsically linked to hydrogen (H2). As the source of hydrogen, its price and its overall environmental impact are still under de...
Rational Development of IT-SOFC Electrodes Based on the Nanofunctionalization of La0.6Sr0.4Ga0.3Fe0.7O3 with Oxides. Par...
To promote the diffusion on the market of solid oxide fuel cell (SOFC) devices, the use of fuels other than the most appealing hydrogen and alsodecreasing the working temperature could show the way forward. In the first part, we concentrated our efforts on cathodes; hereby, we focused on anodes and concentrated our efforts to develop a sustainable ...
Minimizing emissions from grid-based hydrogen production in the United States
Published in Environmental Research Letters
Low-carbon hydrogen could be an important component of a net-zero carbon economy, helping to mitigate emissions in a number of hard-to-abate sectors. The United States recently introduced an escalating production tax credit (PTC) to incentivize production of hydrogen meeting increasingly stringent embodied emissions thresholds. Hydrogen produced vi...

Published in MATEC Web of Conferences
This article describes the issue of hydrogen storage in the structure of metallic alloys and then solves the design and structural analysis in ANSYS Static Structural of low-pressure metal hydride steel vessel for hydrogen storage in metallic alloy based on MnTiVFeZr used for mobile applications.
Analiza procesa metanacije na katalizatorju iz nikljevega(II) oksida nanešenega na osnovo alumine
Katalitična metanacija je kemična reakcija, kjer se iz vodika in ogljikovega dioksida (ali monoksida) proizvede metan oz. sintetični zemeljski plin. Proces predstavlja eno izmed obetavnih rešitev dolgoročnega shranjevanja obnovljivih virov energije in zmanjševanja CO2 emisij, njegovo implementacijo v obstoječe energetske sisteme pa še vedno prepreč...
Computational screening methodology identifies effective solvents for CO2 capture
...
Abstract Carbon capture and storage technologies are projected to increasingly contribute to cleaner energy transitions by significantly reducing CO 2 emissions from fossil fuel-driven power and industrial plants. The industry standard technology for CO 2 capture is chemical absorption with aqueous alkanolamines, which are often being mixed with an...
Is hydrogen production through natural gas pyrolysis compatible with ambitious climate targets in the United States? A l...
Published in Environmental Research Letters
Pyrolysis of natural gas to produce H2 and solid carbon through methane cracking can be characterized as a high-CH4, low-CO2 process. It results in low CO2 emissions because no direct CO2 is generated at the point of H2 generation if solid carbon is not combusted further. However, it results in high CH4 emissions because of its higher natural gas c...
A review on best practices using hydrogen fuel-cell electric vehicles in public transport
Published in IOP Conference Series: Earth and Environmental Science
Road transportation sector is responsible for 21.8% of EU’s CO2eq emissions forcing the shift to a de-carbonised mobility scheme, whilst maintaining competitiveness and satisfying the increasing demand mobility needs. Thus, the development of electric vehicles (EVs) and the investigation of alternative fuels by the research community have emerged. ...
Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1$s$ hyperfine splitting of muonic hydrogen
...
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen ($\mu$p) with 1 ppm accuracy by means of pulsed laser spectroscopy. In the proposed experiment, the $\mu$p atom is excited by a laser pulse from the singlet to the triplet hyperfine sub-levels, and is quenched back to the singlet state...
