This resilience to impurities is particularly advantageous in the transportation sector, where the shift to high-quality green hydrogen is a gradual process. Electrolytic hydrogen produced with renewable power reaches a high purity level since in the worst case, the electrolyzer outflow is hydrogen ...
If you are unfamiliar with summation notation, here is an easier way to remember the concept of NPV:1 NPV=Today’s value of the expected cash flows−Today’s value of invested cash\begin{aligned}NPV=\text{Today's value of the expected cash flows}-\text{Today's value of invested cash...
in free cities boosted the status of arithmetic and record-keeping, for “every saleable item is at the same time a measured item,” as one medieval philosopher put it. Even the new polyphonic music required a visual notation and a precise, metrical view of time. That a new era had ...
