Zero Emissions Ship Technology Association

 

The roar of the tide of change

Our purpose is to promote rapid and large-scale uptake of Zero Emissions Ship Technology (ZEST). Zero Emissions means zero GHG emissions at point of use on the vessel with minimal upstream impacts. By combining zero emission technologies, we achieve zero emissions at a shipboard level faster. With today’s technologies we can achieve fully zero emissions now, particularly on smaller return to base vessels, and drastically reduce emissions on larger ocean going vessels with more complicated operational profiles.

“ZESTAs is like a lego set where no matter how you put together the pieces they always add up to zero.”

Battery system

Batteries

Marine batteries are containers of one or more cells in which chemical energy is converted into electricity.

Modularity means that energy capacity can range from tens of kWh to multiple MWh, while power delivery is instant. Because the electricity is used directly with no conversion, batteries have the greatest energy efficiency of any fuel or energy storage system.

Battery system

Hydrogen

Hydrogen when used as a fuel in hydrogen fuel cells provides efficient, silent, zero emission power generation.

Fuel cells convert hydrogen and oxygen into electricity, heat and pure water via an electrochemical energy conversion process, producing no NOx, SOx or CO2 emissions at all. Therefore, hydrogen fuel cells can be used on board vessels…

Battery system

Wind

Wind propulsion is experiencing exponential growth in merchant shipping, including ocean-going vessels of > 100,000 dwt.

Wind propulsion technologies harness free and renewable energy from the wind to propel vessels. When used to assist other methods of propulsion, as is often the case with retrofits, wind propulsion can provide ~ 20% of propulsion…

Our mission is to:

  • Promote the interests of the Zero Emissions Ship Technology Industry

  • Inform regulators, policymakers, and the shipping industry about available zero emissions ship technologies (ZEST)

  • Influence regulators and policymakers at national and international levels to introduce legislation that necessitates the uptake of ZEST

  • Create a collaboration platform for ZEST providers

  • Prevent catastrophic climate impacts by assisting commercial shipping to reduce emissions on a steep trajectory in line with 1.5 degrees

THE UN IPCC WARNS WE HAVE ONLY 9 YEARS TO PREVENT CLIMATE CHANGE CATASTROPHE

 

Together we are legion. Our combined voices cannot be ignored but we must speak in harmony for our message to be heard
