Implementing the OECD Framework for Industry’s Net‑Zero Transition in Egypt

Annex C. Investment need assessment

Objective

This annex includes detailed results of the investment need assessment that is discussed in Chapter 3.

Result

The two scenarios used for the LCOH calculation of green hydrogen presented in Chapter 2 were selected based on achieving the lowest LCOH values. In particular, based on the results of Scenario B, several important considerations emerge. The estimated land footprint for PV power plants with a total capacity of 12.47 GW is approximately 171.5 km². For nearshore wind power plants with a capacity of 20.07 GW, the estimated land requirement is significantly larger, at around 624.3 km². In addition, storing 6 438.6 tonnes of hydrogen (tH₂) at a pressure of 200 bar would necessitate high-pressure storage tanks with a combined capacity of approximately 400 000 m³.
