Complete a FEED study

FEED Study Guidelines

For each clean hydrogen project, you must complete a Front-End Engineering Design (FEED) study or an equivalent engineering study and submit it as part of your clean hydrogen project plan submission. An equivalent engineering study would correspond with an engineering package at the Front-End Loading 3 (FEL-3) stage. Documents provided for the FEED or equivalent study must cover all elements relevant to eligible clean hydrogen property and carbon intensity (CI) determination in the production of clean hydrogen and requirements of a clean hydrogen project plan, including the following as applicable:

  • The clean hydrogen production facility (including any on-site fuel or feed storage or preparation equipment)
  • Any carbon capture, transportation, or storage equipment
  • Any on-site clean hydrogen storage
  • Any on-site clean hydrogen transportation infrastructure
  • The clean ammonia production facility, applicable to clean hydrogen projects that produce clean ammonia
  • Any infrastructure related to transportation of clean hydrogen between the hydrogen production facility gate and the ammonia production facility inlet, applicable to clean hydrogen projects that produce clean ammonia

Instructions for preparing the requested diagrams for the FEED study or equivalent

Prepare two separate sets of annotated drawings for the FEED (or equivalent) study:

  • One set to support clean hydrogen project confirmation, which must adhere to the instructions below:
    • Clearly label all locations along the diagrams that delineate the process boundary between the clean hydrogen project and other projects using dashed green lines that are distinct from any other labelling on each diagram
    • In case of clean ammonia production, clearly delineate and label the process boundary between the clean hydrogen and clean ammonia processes using dashed red lines that are distinct from any other labelling on each diagram
  • A second set to support the validation of the expected CI, which must:

The FEED (or equivalent) study package should at minimum include items 1 through 12 of the table below.

Itemized Class 3 Cost Assessment*

* Cost assessment must be consistent with a Class 3 cost estimate, as outlined by the Association for the Advancement of Cost Engineering.

This cost assessment will not be used by CRA for determination of equipment eligibility as it is strictly a part of the design package.

An itemized list of (estimated) costs that includes

  1. Itemized purchase cost of property
  2. Costs to put the property into service including purchased equipment installation cost, instrumentation and controls and other relevant direct costs (CapEx)
  3. Materials, labour, and overhead costs and other indirect costs reasonably attributable to the CapEx of the clean hydrogen property
