Hydrogen plays an important role in the energy transition towards a zero-carbon economy. Blue hydrogen and green are potential sources to replace fossil materials fuels fields of refining - petrochemical, production fertiliser, steel, cement, electricity, transportation. The demand for clean these areas has been evaluated along with impacts benefits development. Accordingly, market can reach ou...

This review critically analyses various aspects of the most promising thermochemical cycles for clean hydrogen production. While current market heavily relies on fossil-fuel-based platforms, water-splitting systems based reduction-oxidation (redox) looping reactions have a significant potential to significantly contribute sustainable production green at scale. However, compared water electrolys...

In Europe, electrification is considered a key option to obtain cleaner production of steel at the same time as electricity system portfolio expected consist an increasing share varying renewable (VRE) generation, mainly in form solar PV and wind power. We investigate cost-efficient designs hydrogen-based steelmaking systems dominated by VRE. develop apply linear cost-minimization model with ho...

The cleaning of Al, TiN, and Cu blanket samples was investigated in a high density inductively coupled plasma reactor, and compared with results for silicon. After simulating the dielectric overetch exposure of these substrates to a CHF3 discharge, an in situ O2 plasma clean and subsequent Ar premetal sputter clean were performed and evaluated using ellipsometry and x-ray photoelectron spectros...

Surface-induced layering has been observed in liquid gallium and mercury using X-ray reflectivity. The specular reflectivity R(q,) has been measured to wavevector transfers as large as q, = 3.0 A-‘. For Ga, the only major deviations from pesnel theory R, are near q, = 2.4 A-‘, where there is a peak in the ratio R/R,. For Hg, there is a broad peak near 2.15 A-‘. The data have been collected on a...

Industries across the world are making transition to net-zero carbon emissions, as government policies and strategies proposed mitigate impact of climate change on planet. As a result, use hydrogen an energy source is becoming increasingly popular field research, particularly in aviation sector, where alternative, green, renewable fuel traditional hydrocarbon fuels such kerosene essential. Hydr...
