mFGD (NSW^®)

Since January 2000, the first batch of power station mFGD systems designed by ZCE (total 6GW) have been put into commercial operation; by 2023, the global installed capacity of deployed mFGD systems is estimated to be no less than 30GW, and will continue to grow.
More than 20 years of commercial operation have proven that mFGD uses only natural seawater (no chemicals), achieves 90%+ desulfurization and ~5% carbon removal, has a higher desulfurization rate than chemical FGD systems, reduces costs by 80%, and is marine ecologically friendly.
This has promoted the advancement of clean energy technology: the transition from traditional artificial chemical systems to natural seawater systems.

mEGC (NSW^®)

In 2011, the world's first marine mFGD (using only seawater and no chemicals), an "open" EGC system developed and manufactured by ZCE, was successfully tested on the RUIHE tanker (IMO No.9485019); It is estimated that by 2024, there will be more than 6,000 marine ships using open EGC systems worldwide, and the number will continue to grow.
On November 8, 2012, ZCE was invited to give a keynote speech at Stanford University on “Environmental Technologies in Maritime Shipping & Transportation: Implementing the New UN Protocols". The published sea trial information of RUIHE tanker, especially the key parameters such as the pH value of the discharge water, provided a basis for the revision and improvement of the 2013 IMO MEPC/EPA VGP (2008~2013).

Previously, the "MS ZAANDAM" project funded by the US and Canadian governments and invested by BP also obtained some parameters after years of testing. (Final report of the US EPA’s "MSZAANDAM" project, March 31, 2010).
