Ghana's Petroleum Hub Development Corporation signed a memorandum of understanding worth about US$28 billion with an investment consortium led by Global Sphere of the United Arab Emirates. The agreement covers Lot 2 of Ghana's Petroleum Hub project and was signed in Accra on Monday. Its announcement has revived optimism in Ghana's energy sector and among other African energy stakeholders. Supporters see the project as a step toward stronger African energy security. Because the deal is a memorandum of understanding, the reported value does not mean construction has begun or that financing has closed. The parties now need to clarify the scope of work, investment schedule and regulatory approvals required for the project. Accra will be judged on whether the signing leads to concrete commitments.
