Shipping decarbonization goals


The path we are on today
We are heading for an increase in maritime GHG emissions of ~20% by 2050 despite current industry-wide efforts. Growing trade volumes (~1.3% CAGR trade growth), technological developments and existing CO2 reduction initiatives across the sector will not give shipping enough traction to deliver what is needed to meet the current IMO targets. Shipping needs to step up.

IMO 2030 & 2050 (see infographic)
The International Maritime Organization has taken measures with clear targets to tackle climate change and reduce carbon emissions from shipping. However it's expected that national and local legislation call for even more stricter and sooner targets.

It also seems to be only a matter of time that carbon taxes will come into force in one way or the other for the shipping industry worldwide.

What can, and needs to be done?
It is important for ship owners to prepare themselves thoroughly and sustainably for the future, in which ever stricter requirements will be imposed on the emission of greenhouse gases. In basic there are 3 options for carbon reduction;

  1. Use less of the current (carbon intensive) fuels
  2. Switch to synthetic / non-carbon fuels (E-fuels)
  3. Carbon capture

1.   Use less of the current (carbon-intensive) fuels

Using less fuel and/or improving efficiency is a good thing and pays off in terms of reduced emissions. Therefore, it should be done whenever possible, but there are limits to what can be achieved in the longer term.

Lowering fuel consumption
 Logistics (optimized route planning, vessel utilization)
 Hydrodynamics (hull optimization, air lubrication, cleaning)
 Machinery (waste-heat recovery, engine de-rating, battery hybridization)
 Use/blend of less carbon-intensive fuels (LNG, LPG, Hydrogen & Methanol from CH4, Biodiesel)

IMO2050 compliance: ❌

2.   Switch to non-carbon fuels (E-fuels)

The most sustainable solution is to switch to carbon-free fuels, such as ammonia or methanol & hydrogen from green energy.

However, these E-fuels are still in their infancy and renewable energy sources will not be sufficiently available to produce the required amount of e-fuels necessary in the medium to long term.

3.   Carbon Capture

The currently most certain strategy for reducing CO2 emissions is to capture the CO2 released from the exhaust gases during combustion. The CO2 can be used to make Methanol based on green energy. This methanol has a low carbon intensity and can be used again on board as ships fuel creating a carbon neutral cycle. Eventually it also contributes to a more gradual transition to synthetic fuels.  

The carbon capture system requires hardly any modifications to the current engine system and is compliant to IMO 2050. The system can be integrated into new build vessels and can also be retrofitted to existing vessels.
