Infrastructure Management for Power Capture in the Identify stage

Objective

To identify the requirements, constraints and costs of infrastructure for the power and capture plant options.

Major Deliverables

• Identification of main requirements for each power, capture plant option:
  • Rail, road
  • Electrical power connections (high voltage (HV), medium voltage (MV), and low voltage (LV))
  • Heat/steam
  • Land
  • Raw and demineralised water
  • Cooling water, storm water
  • Gas or other fuels
  • Waste management
  • Information technology (IT)/communications
  • Sewerage and storm-water drainage
  • Fire water or other protection systems
  • Solvent, oxygen/nitrogen, other chemicals supplies
  • Stores
  • Laboratory, office, workshops if required
  • Identification of potential infrastructure-related constraints for each capture option
  • Identification of potential solutions and indicative costs for these constraints

Tasks

Specific tasks include the following:

• List all capture options under consideration (location/type/size)
• Identify at a high level likely requirements of each capture method or capture/power pnat combination in terms of:
  • Rail, road
  • Electrical power connections (high voltage (HV), medium voltage (MV), and low voltage (LV))
  • Heat/steam
  • Land
  • Raw and demineralised water
  • Cooling water, storm water
  • Gas or other fuels
  • Waste management
  • Information technology (IT)/communications
  • Sewerage and storm-water drainage
  • Fire water or other protection systems
  • Solvent, oxygen/nitrogen, other chemicals supplies
  • Stores
  • Laboratory, office, workshops if required.
• Identify where any of these requirements would be problematic at that location/power plant site. This may include, e.g. consideration of:
  • Impact of reduction in power output on power supply agreements in place
  • Availability of land
  • Cooling water extraction and discharge licences already in place at that location
  • Supply chain availability for inputs to process
  • Disposal of waste material produced from the capture process
  • Access to existing facility for retrofit
• Identify possible mitigation methods for issues identified. This should include consideration of resulting impacts. These mitigation methods may include:
  • Dedicated additional plant and/or boilers to provide power and/or steam to capture process
  • Modular construction of capture plant and/or placing some modules/equipment above others to maximise use of space
  • Purchase of additional land
  • Location of some elements of capture plant at a distance from power plant, with ducting/pipework as required
  • Air-cooling
  • On-site production of oxygen, nitrogen
  • On-site waste treatment system and recycling
  • Careful planning for retrofit works to be carried out during plant long term shutdown period to minimise plant downtime
• Produce written description of issues associated with infrastructure for each capture option and whether any are potential fatal flaws.
• Identify major differences in infrastructure requirements and determine whether any can be used to eliminate options
• Identify alternatives for providing the required infrastructure and/or possible solutions to constraints and issues.
• Identify tasks to be undertaken on remaining options to enable decisions to be made in the evaluate stage
