EPA releases national assessment of strategies to reduce air pollution at ports
September 23, 2016
A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. Implementing these approaches, the report finds, would reduce greenhouse gas and other harmful emissions from diesel-powered ships, trucks and other port equipment.
“The National Port Strategy Assessment: Reducing Air Pollution and Greenhouse Gases at US Ports” examines current and future emission trends from diesel engines in port areas, and explores the emissions reduction potential of strategies like replacing and repowering older, dirtier vehicles and engines and deploying zero emissions technologies.
Kenworth receives $8.6M in grants for low-emission T680 Day Cab drayage truck projects in California; hybrids, CNG hybrid and fuel cell
August 20, 2016
Kenworth has been awarded three government grants totaling $8.6 million that will support low emissions projects involving Kenworth T680 Day Cabs targeted for use as drayage tractors in Southern California ports.
The first two projects are funded at $1.9 million each by the US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE), with Southern California’s South Coast Air Quality Management District (SCAQMD) as the prime applicant. Kenworth will build two, proof-of-concept T680 Day Cab drayage tractors to transport freight from the Ports of Los Angeles and Long Beach to warehouses and railyards along the I-710 corridor in the Los Angeles basin.
US Navy completes sea trial with ARA’s 100% drop-in renewable diesel fuel
August 09, 2016
A Navy ship has, for the first time, operated on a 100% drop-in renewable diesel fuel. Naval Surface Warfare Center, Port Hueneme Division’s (NSWC PHD) Self Defense Test Ship (SDTS) completed final-phase testing of a 100% drop-in renewable diesel fuel as part of the Navy’s MILSPEC qualification program. ReadiDiesel was developed by Applied Research Associates (ARA) and Chevron Lummus Global, as a drop-in replacement for petroleum F-76 marine diesel. ReadiDiesel is a 100% renewable biofuel. (Earlier post.)
The SDTS took on approximately 18,000 gallons of ReadiDiesel in San Diego, California. The objective of this particular test was twofold: first, to demonstrate that ReadiDiesel is a drop-in replacement for petroleum-sourced F-76 marine diesel, meaning that it requires no blending with petroleum-derived fuels, equipment modifications or operational modifications by the crew; and second, to ensure that this renewable fuel performs equally to, or better than, existing petroleum-derived fuels.
New study finds that ship emissions from HFO and diesel adversely affect pulmonary macrophages
July 20, 2016
A study by European researchers has found that ship emissions from the combustion of heavy fuel oil (HFO) and diesel fuel (DF) have adverse effects on pulmonary macrophages, from increased cell death to altered metabolic profile, depending upon the aerosol component. Their open access paper is published in the journal PLOS ONE.
Macrophages are white blood cells and are part of the immune system. Often referred to as scavenger cells, they absorb and engulf microorganisms. In addition, the cells destroy tumor cells, remove cell debris, present antigens and promote wound healing. There are four types of pulmonary macrophages: alveolar; interstitial; intravascular; and the dendritic. The alveolar macrophages are the only macrophages in the body which are exposed to air. Located at the interphase between air and lung tissue, they represent the first line of defense against inhaled airborne elements.
Efficient Drivetrains selected as part of $8.2M San Diego port electrification project
July 19, 2016
Efficient Drivetrains, Inc. (EDI), a developer of high-efficiency hybrid and electric drivetrain solutions, was selected as a drivetrain provider and vehicle integrator for an electrification program driven by the San Diego Port Tenants Association (SDPTA). Also selected as part of the San Diego project were BYD and Transportation Power. Technology subcontractors are Peloton, GC Green, Greenlining Institute, and carbonBLU.
As part of the program, EDI will create a series of EV port trucks, and electrifying forklift vehicle accessories. The electrified port trucks will be used to replace conventional fuel vehicles of the same specifications with 100% emissions reduction, while still maintaining the same power and performance. Electrification of the forklift will eradicate emissions by eliminating engine idling while performing standard vehicle operations in the port.
Ricardo and Recycling Technologies to characterize Plaxx plastic-waste-derived-fuel for marine applications
July 05, 2016
UK-based Recycling Technologies is industrializing a process—originally developed at the University of Warwick (UK)—to convert residual plastic waste into a low-sulfur hydrocarbon compound called Plaxx. Plaxx is created from residual mixed plastic waste that is not amenable to direct recycling and would otherwise go to landfill.
The company, a 2013 spin-out from the University, is now working with Ricardo to characterize the use of this recycled, low-sulfur fuel as a substitute for fossil based heavy fuel oil (HFO) and diesel in applications such as power generation and marine propulsion.
Scripps research ship fueled by 100% NEXBTL renewable diesel for 1 year; emissions analysis
June 14, 2016
In 2014, Scripps Institution of Oceanography received a grant from the US Department of Transportation to test the use of biofuel on the research vessel Robert Gordon Sproul for more than a year. Spearheaded by Scripps Associate Director Bruce Appelgate and co-led by Scripps atmospheric scientist Lynn Russell, the biofuel project investigated the viability of using hydrotreated renewable diesel fuel (HRD) on a long-term basis.
The Scripps researchers originally wanted to test renewable biodiesel produced from algae, but no manufacturers made algal biodiesel in the volume needed. Appelgate was able to take advantage of a newly-established reliable supply chain for another type of biodiesel, a hydrogenation-derived renewable diesel (HDRD) —purchased from Neste Oil Corporation: NEXBTL Renewable Diesel.
California to award $9M for 27 BYD zero-emission trucks at two rail yards, one freight transfer yard in Southern California
June 10, 2016
The State of California is awarding $9 million to the San Bernardino Associated Governments (SANBAG) for 27 zero-emission trucks to replace diesel-powered heavy-duty tractors used in rail yards and large-scale freight distribution centers. The funds come from the California Climate Investments (CCI) program and are designed to reduce greenhouse gases (GHG), while also reducing petroleum usage and improving air quality in residential communities.
The two types of trucks funded by this grant are the most common at every major freight location in the US, providing a model for truck electrification that could be scaled to any facility. The project will demonstrate 23 battery-electric 80,000-pound (GVWR) Class 8 yard trucks, also known as “yard goats,” which are used to move heavy freight containers short distances within freight yards, warehouses, distribution centers and port terminals.

Damen delivers hybrid tugboat to Royal Netherlands Navy; up to 30% lower fuel consumption, 40% fewer emissions
March 25, 2016
International shipyard group Damen recently delivered the first of a series of three hybrid tugboats (ASD TUGs 2810 Hybrid) to the Royal Netherlands Navy (RNLN). This 28.67-meter hybrid tug is named Noordzee and is the first standard hybrid tug supplied by Damen that the RNLN will employ. Compared with other tugs, hybrid versions use up to 30% less fuel and produce 40% fewer exhaust emissions.
Currently, the RNLN has four conventional tugs in Den Helder. However, these older vessels do not have sufficient power to tug new ships such as the HNLMS Karel Doorman (logistic support ship, 28,246 t full load); HNLMS Rotterdam (landing platform dock, 14,000 t full load); and the HNLMS Johan de Witt (landing platform dock, 16,800 t full load). Furthermore, the old vessels still make use of normal propellers with rudders with a restricted maneuverability and no longer fit the vision of sustainability that the RNLN has for the future.

The highly efficient (MGPM) may offer significant benefits for marine propulsion by increasing the electrical efficiency by up to 7% compared to existing state of the art electrical machines.
Study finds substantial increase in nanoparticles in air as it crosses the Baltic Sea; shipping emissions responsible for about half
November 23, 2015
A study by a team of international researchers has found that air crossing over the main basin of the heavily ship-trafficked Baltic Sea shows a “substantial” increase in the number of 50–400 nm particles (50–400N). An open-access paper on their work is published in the journal Oceanologia.
The researchers evaluated 10 months worth of data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden); Utö (upwind, Finland); and Preila (downwind, Lithuania).
