FEL1
FEL1 defines the opportunity, order-of-magnitude potential, critical constraints and strategic fit. It is used to decide whether deeper engineering is justified.
FEL2 and FEL3
FEL2 compares credible architectures and develops the preferred option. FEL3 prepares the project for approval with refined scope, CapEx, OPEX, schedule, risks and procurement basis.
Engineering FAQs
Why use FEL for decarbonization?
Because thermal transformation touches production, utilities, controls and CapEx. FEL creates disciplined decisions instead of technology bets.
