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.”
Madadh MacLaine, Secretary General
Combined Technologies
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.
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…
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

ZESTAs Achieve Major Milestone with First Submission to International Maritime Organisation
ZESTAs is committed to driving innovation in the shipping industry. In doing so, we are about to reach a major milestone by submitting a detailed white paper to the International Maritime Organisation (IMO) for the first time. This groundbreaking submission, ISWG-GHG 15/INF.2, provides the latest information concerning demonstrated zero emission shipping technologies and the extent of their commercialisation.
