REALISE cases 1 & 2

• re-run cases with GWA2
• clarify LCOH calculation - why can the business case be postive when LCOE is higher than avg. el-price (because of fluctuations) and LCOH higher than constant H2 price.
• consider switching to presenting the H2 price that gives zero NPV. This can be implemented in the finance module similary to how IRR is computed. (break even price)
• add capacity factor from wind only to the output
