Ethanol emerges

This article, contributed to Splash by WinGD, explains why ethanol is a good temporary marine fuel. The WinGD engines were built to run on methanol, but can easily be adapted to burn ethanol. And ethanol is readily available commercially, especially in Brazil and the US, at a competitive price with normal marine fuels.

The article explains how burning ethanol will lower the fuel emissions factor to more than four times lower than VLSFO. For a company interested in lowering its carbon emissions profile now, this is a big boost.

Such a firm is Vale, the international mining company, which supplies iron ore to China from Brazil and elsewhere. Brazil produces ethanol in large quantities, since it’s banking on ethanol for emissions reduction in autos.

Ethanol is certified for the EU Emissions Trading System, but not under FuelEU. That’s a hurdle that needs to be overcome in the near future. But much shipping that can use ethanol does not touch European ports, and so can avoid carbon charges and regulation while still reducing carbon pollution.

The latest Maersk vessel to feature a WinGD methanol-fuelled X-DF-M engine is the 9,000 TEU Tema Maersk. Its sister ship Tangier Maersk is pictured here.

WASP project ends as winds blow fair

The EU’s Wind Assisted Ship Propulsion (WASP) project has ended. So far we seem to have favorable findings concerning the viability of retrofitting ships with wind propulsion units in addition to conventional power.

Estimates seem to be coming in at up to 10% savings. This is in the North Sea, where the winds blow heavy. However, 10% is not to be sneezed at. It’s a significant reduction in both energy and GHG emissions.

The picture of a bulker fitted with the sails shows one way to add the wind power.

Cooperation between shipowners and technology developers as well as university researchers is key. The list of partners is impressive.

This statement is from their website:

“The project brings together universities, wind-assist technology providers with ship owners to research, trial and validate the operational performance of a selection of wind propulsion solutions on five vessels thus enabling wind propulsion technology market penetration and contributing to a greener North Sea transport system through harvesting the region’s abundant wind potential.”

WASP has published their last newsletter, and also other publications. It’s interesting reading. There is also a final webinar.

Since I sailed as a kid, I’ve been interested in commercial applications of wind power. It’s exciting to see new engineering marvels tailored for the maritime world. Let’s hope the WASP research will lead to more and better wind power for ships.
