• Operating data and ranges (temperatures, pressures, flow rates);

• Battery limit conditions; and

• Plant location and climatic data.

2.Process Flow Diagram (PFD) with Mass & Energy Balances

Develop a fully annotated PFD including:

• All main equipment and machinery with tag numbers;

• Main process lines with flow direction arrows;

• Incoming and outgoing product and auxiliary streams;

• Numbered flow reference points for all important streams; and

• Main control loops for process and safety purposes.

Balance documentation shall include flow rates, operating conditions (P, T, density), auxiliary

flows, volumetric flows, enthalpies of main streams, and electricity consumption of key

equipment.

3 Piping & Instrumentation Diagram (P&ID)

• Familiarity with European pressure equipment regulations (PED) and relevant safety

standards;

• Experience working within or alongside climate-tech or carbon capture projects; and

• Ability to work independently with minimal supervision in a fast-paced scale-up

environment.

3 Soft Skills & Working Style

• Strong self-organisation and ability to manage deliverable schedules;

• Clear written and verbal communication suitable for technical and management
