Clean Diesel Technologies awarded $1.3M for ferry emission reduction program

Clean Diesel Technologies, Inc. has been awarded $1.3 million in funding by the New York State Energy and Research Development Authority (NYSERDA) to supply diesel emission control technology as part of a New York City ferry emission reduction program.

The agreement follows a successful demonstration phase in which test vessels were fitted with diesel oxidation catalysts (DOCs) and proven to reduce diesel particulate matter and other harmful emissions significantly. Over the next several months, CDT will supply and manage the installation of the emission control technology. Each vessel will then be subject to an evaluation period simulating normal passenger operation prior to being released for normal use.

The program will implement emissions control technologies on private ferries operating in New York Harbor. Marine engines are responsible for the emission of many tons of nitrogen oxide (NOx), an ozone-forming compound, as well as particulate emissions (soot) into the New York airshed. As these emission sources are mostly unregulated, the city and state are attempting to develop an incentive program to produce the desired emissions reductions from marine sources.

In addition, CDT announced that the California Air Resources Board (CARB) has expanded its approval (verification) of the ECS Purifilter Plus as a Level 3+ device to include exhaust gas recirculation (EGR) heavy duty on-road vehicles.

The ECS Purifilter Plus emissions reduction product is the first hybrid diesel particulate filter (DPF) system employing both passive and active regeneration that has been verified by both the Environmental Protection Agency (EPA) and CARB for a wide variety of heavy duty diesel on-road engines, CDT says.

ECS PurifilterPlus combines a passive ECS Purifilter and the active regeneration components of an ECS Combifilter which result in a hybrid diesel particulate filter which has no minimum exhaust temperature requirement and is maintained through active regeneration by periodically plugging the system into a 240V single-phase or 480V three-phase regeneration control panel that may be shared between several vehicles. This approach greatly reduces the maintenance requirements when compared to traditional passive DPF solutions.

Have DLM convert the ferries to fuel oil operated steam engines and the air will clean right up and at lower cost. Or they could go to microturbine electric drive with steam assist for very clean and efficient operation. ..HG..

@HG: Diesel is cheaper and more fuel-efficient, especially with larger displacement engines. It is probably cheaper to clean up diesel exhaust than it is to switch to cleaner burning Rankine or Brayton cycle.
