Green hydrogen cost-potentials for global trade
نویسندگان
چکیده
Green hydrogen is expected to be traded globally in future greenhouse gas neutral energy systems. However, there still a lack of temporally- and spatially-explicit cost-potentials for green considering the full process chain, which are necessary creating effective global strategies. Therefore, this study provides such detailed cost-potential-curves 28 selected countries worldwide until 2050, using an optimizing systems approach based on open-field photovoltaics (PV) onshore wind. The results reveal huge potentials (>1,500 PWhLHV/a) 79 PWhLHV/a at costs below 2.30 EUR/kg dominated by solar-rich Africa Middle East. Decentralized PV-based production, even wind-rich countries, always preferred. Supplying sustainable water production needed while having minor impact cost. Additional imports from democratic regions only total 7% higher. Hence, could boost geostrategic security supply

Global Warming Potentials: A Cost-Effectiveness Approach
The Kyoto Protocol prescribes obligatory limits on the emission of greenhouse gases by the industrialized countries during the period 2008-2012. Six specific gases are covered. The Kyoto limits apply to an aggregate of emissions of the covered gases expressed in carbon dioxide (CO2) equivalents, obtained by application of a "global warming potentials" (GWPs). In regard to concentrations, or sto...

15 صفحه اولNew hydrogen-like potentials
Using the modified factorization method employed in [5], we construct a new class of radial potentials whose spectrum for l = 0 coincides exactly with that of the hydrogen atom. A limiting case of our family coincides with the potentials previously derived by Abraham and Moses [6].
