The Cost of Construction for a Hydrogen Plant with a Capacity

Short Answer

The cost of construction for a hydrogen plant with a capacity of 7000 standard cubic feet per day (scfd) was $10 million ten years ago, when the current construction cost index was 4535. If the index increased at an average rate of 6.8% per year for the past ten years, what would a(n) 12,000- scfd plant with a similar design be expected to cost now? Use the
cost- capacity exponent of 0.56.
