Make a business case for a container ship refit to shore power

This is a techno-economic case study that provides guidance for decarbonizing a ship by means of a shore power refit, taking a feeder as a case study. Shore power will be made mandatory by 2030 for these ship types as per FuelEU Maritime regulation. A step-by-step approach is given to estimate costs, analyse technical feasibility, and create a business case for the shore power refit in general. Use the Shore Power Quickscan to make your own business case, and contact the helpdesk for clarifications.

Case study is the ‘E-Feeder’, a container ship or feeder, with an average of approx. 100 [kW] power demand while moored.
Assumed is that a 100% CO2 reduction is achieved when using shore power, which complies to FuelEU Maritime as well.
CAPEX costs are estimated at around €300k. Biggest impact are switchboard modifications, connection panels and a transformer on board.
Payback time is approximately 6 years, pending assumptions on fuel and electricity costs. FuelEU Maritime savings in the first 10 years are approx. €300k.

The study was performed with consortium members InnovationQuarter, Bluewater, Knutsen, EOPSA, Rijkswaterstaat, Campus@Sea, Port of Rotterdam, KVNR and Cavotec. This lunch and learn is the recording of the close-out session in which main findings were presented.

Project BOEI

Project BOEI is a techno-economic feasibility study on behalf of the Province of South-Holland on the electrification of tankers at the Scheveningen anchorage. The goal is to identify the most feasible technical solutions and risks, in addition to cost and emissions reduction estimation. Primary drivers are reduction of NOx and CO2 emissions. Total costs for all scopes combined is €14M (~€12M for infra and ~€2M for ship). E-anchor and subsea cabling are approximately 50% of all cost. Break-even price parity for shipowner and provider of power is at around €0.20-€0.25 per kWh.

Mobilyze Renewable Energy Units (HBEs) with Robert Gunsing

Renewable Energy Units - Hernieuwbare Brandstof Eenheden - are a Dutch system of certificates based on the EU Renewable Energy Directive (RED). Under the system, parties that produce liquid fossil fuels for transport have an obligation from the government to purchase REUs. Per year, €1 billion REUs are traded in the Netherlands. You can earn between 4.5 and 18 eurocents per kWh ‘sold’ to a vessel, for example when using shore power.

How to decarbonize your ship - Inland Waterways + Shore Battery

This is a case study on the ‘Skoon Skipper’, a general cargo large Rhine vessel, with an average of 40 [kW] power demand while moored to which a shore battery is applied.
