Parameters

• CO2 and NOx taxes

• Wind and power profiles

• Efficiencies

• Unit costs

Targets and constraints

• CO2 reduction target

• Availability

• Minimum cost

Variables

• Filling of storage

• Size of units

Results

• Lifetime costs

• Size of system

Assumptions• Power demand profile, max: 34.5 MW• Norwegian Continental Shelf wind profile, capacity

factor 0.56• Current CO2 tax: 700 NOK/ton• CAPEX and OPEX based on 2025 forecast• Discount rate: 4%

Results• Energy storage required to reduce CO2 emissions more

than 50%

• Abatement cost of Deep Purple competitive with power cable from shore in 2025

• Abatement cost of Deep Purple with bottom-fixed wind competitive with gas turbine up to 70% CO2 reduction

Abatement cost of Deep Purple to an oil&gas installation
