Published at Applied Energy – Systematic assessment for an integrated hydrogen approach towards the cross-regional application considering solar thermochemical and methanol carrier
Abstract Hydrogen holds promise as a clean energy carrier, but its industrial utilization is currently constrained by the challenges of green production and efficient cross-regional delivery. To this end, a novel integrated hydrogen energy system considering the...
Published at Journal of the American Chemical Society – Chemical Potential Analysis as an Alternative to the van’t Hoff Method: Hypothetical Limits of Solar Thermochemical Hydrogen
Abstract The van’t Hoff method is a standard approach for determining reaction enthalpies and entropies, e.g., in the thermochemical reduction of oxides, which is an important process for solar thermochemical fuels and numerous other applications. However, by...
Published at Royal Society of Chemistry – Thermochemical production of ammonia via a two-step metal nitride cycle – materials screening and the strontium-based system
Abstract Ammonia synthesis via the catalytic Haber–Bosch process is characterized by its high pressures and low single-pass conversions, as well as by the energy-intensive production of the precursors H2 and N2 and their concomitant greenhouse gas emissions....
IRA incentives for clean energy from idle oil wells
Climate policy in the US Inflation Reduction Act (IRA) provides powerful incentives to generate renewable energy and phase out fossil fuel production. Oil and gas companies are already required to cap boreholes when an oil well is depleted, to meet Asset Retirement...
