The Nikkei reports that Kawasaki Heavy Industries Ltd. (KHI) will build the first ocean-going ships to carry liquefied hydrogen (LH2), with plans for a demonstration test by 2017 in which liquefied hydrogen will be shipped from the state of Victoria in Australia to Japan. The project will cost ¥60 billion (US$610 million), according to the report.
As part of Japan’s WE-NET (World Energy Network) research program of the New Sunshine Project begun in 1993, Kawasaki and its other industrial colleagues in Japan have been considering the large-scale marine transportation of liquid hydrogen for some time (e.g., Abe et al., 1998). KHI has previously discussed the concept of such a hydrogen-carrying vessel as part of its Business Vision 2020.
Royal Academy of Engineering study examines future lower-carbon ship powering options
July 26, 2013
International shipping contributes an estimated 3% of global emissions of CO2. Although the industry has reduced its consumption of fossil fuels by a number of measures such as using increasingly thermally efficient diesel engines in recent decades, the current total fuel oil consumption is in excess of 350 million tonnes per year (about 98.5 billion gallons US).
A new study by an expert working group at the UK’s Royal Academy of Engineering examines a wide range of possibilities for future, lower-emitting and cost-effective ship powering options. The report reviews a range of short-, medium- and long-term technologies and examines the advantages and limitations of systems from solar and wind power, through fuel cells to nuclear propulsion. One of the key takeaways is that an integrated systems engineering approach is required to achieve effective improvements in efficiency and reductions in emissions for ships. This integrated approach must embrace all of the elements of naval architecture, marine and control engineering alongside operation practices.

Caterpillar Marine Power Systems has introduced the the Cat Powered Marine Hybrid System, a complete hybrid propulsion package applicable to all engine platforms. Developed with systems integrator Aspin Kemp & Associates (AKA), the package utilizes AKA’s XeroPoint Hybrid marine propulsion system and provides fuel savings of up to 25% and corresponding emissions reductions.
The XeroPoint Hybrid system consists of a diesel engine and an electric motor that independently or simultaneously drive a propulsion shaft. The system is targeted to vessels that have a duty cycle profile with extended periods of low- to medium-power requirements, as diesel engines are least efficient at these load levels. Application examples are workboats; platform supply vessels and offshore supply vessels; research and scientific vessels; fishing boats; and leisure and eco-tourism boats (e.g., whale-watching.)

On 1 July MAN Diesel & Turbo announced the development of a new ME-LGI dual fuel engine. The new engine expands the company’s dual-fuel portfolio, enabling the use of more sustainable fuels such as methanol and Liquefied Petroleum Gas (LPG).
MAN has now signed a Letter of Intent with Vancouver-based Waterfront Shipping for the use of four MAN ME-LGI engines on its ships. The engines will run on a blend of 95% methanol and 5% diesel fuel.
BASF and Samsung Heavy develop new anti-sloshing, anti-boil-off solution for LNG tankers
July 08, 2013
|The BASF/SHI anti-sloshing solution consists of a blanket of blocks of Basotect foam with buoys, which are stitched into Vectran textile covers and connected with Vectran belts. Click to enlarge.|
BASF and the South Korean company Samsung Heavy Industries (SHI) have developed a new concept to prevent the sloshing of liquefied natural gas (LNG) during its transport in tankers. The anti-sloshing solution is a kind of blanket consisting of cubes with a volume of one cubic meter, made of the BASF foam Basotect. The open-cell foam made from melamine resin stays flexible even under cryogenic conditions; the ship’s steel tanks must remain cooled to -162 ° C to keep the gas liquid.
More than a quarter of the global production of natural gas in 2011—nearly 331 billion cubic meters—was liquefied and shipped throughout the world in ocean-going tankers. In preparation for transport, the gas is cleaned, liquefied at -162 °C, and then loaded onto tankers that carry liquid cargo. This process reduces 600 cubic meters of gas to one cubic meter of LNG (liquefied natural gas).
Sandia study finds fuel cell barges may be attractive lower-cost cold-ironing solution for some types of vessels at some ports

A study by researchers at Sandia National Laboratories found that hydrogen fuel cell barges may be both technically feasible and commercially attractive as a clean, quiet and efficient power source to provide electrical power for some types of vessels at berth or at anchorage. This practice in which a vessel at berth connects to a source of electricity on the shore is called “cold-ironing”, shore power or Alternative Maritime Power (AMP).
Vessels that are not likely to be technically feasible are cruise ships, refrigerated bulk carriers (reefer vessels), and some types of liquid bulk tankers, according to the study. This, the Sandia team said, is because their multi-megawatt power requirements and potentially long run times would necessitate multiple MW-class fuel cell units and impractically-large stores of hydrogen. Container ships are likely to be feasible, but their power demand depends primarily on the number of refrigerated containers (reefers) on-board.
US Maritime Administration to fund projects on reducing emissions from marine vessels, study on LNG bunkering
June 15, 2013
The US Maritime Administration (MARAD) Office of the Environment has issued two funding opportunities; the first (DTMA-91-R-2013-0020) will award up to an estimated $900,000 for up to 2 projects that demonstrate criteria pollutant emissions of carbon emissions reductions from marine vessels through repowering, re-engining, or using alternative fuel/energy.
The second (DTMA-91-R-2013-0009) will award up to $500,000 for a comprehensive study on the issues associated with the bunkering (supplying a ship with fuel) of LNG for marine vessels. One of the largest obstacles to widespread take-up of LNG as ship fuel—and hence its viability as an option to meet ECA (Emission Control Areas) requirements—is the lack of a bunkering infrastructure, according to Lloyd’s Register.

US DOE to award nearly $18M to 4 biorefinery projects for mil-spec renewable hydrocarbon fuels
April 22, 2013
The US Department of Energy (DOE) will award nearly $18 million to four innovative pilot-scale biorefineries in California, Iowa and Washington that will produce and test drop-in renewable biofuels that meet military specifications for jet fuel and shipboard diesel.
The pilot-scale biorefinery projects selected today will use a variety of non-food biomass feedstocks, waste-based materials, and algae in innovative conversion processes. The projects will demonstrate technologies to cost-effectively convert biomass into advanced drop-in biofuels and assist these organizations to scale up the processes to commercial levels. Recipients are required to contribute a minimum of 50% matching funds for these projects.
Mærsk Group exploring use of lignin-based marine biofuels; CyclOx and B21st
March 20, 2013
With an annual fuel bill of US$7 billion for vessel operations, the Mærsk Group continually considers ways to reduce its bunker fuel consumption. Greater efficiency is the primary way of achieving this; alternative fuels are another. Mærsk Group is currently involved in two projects focused on realizing the marine fuel potential of one of the world’s most abundant and sustainable biomass resources: lignin.
Lignin already has a variety of industrial uses because of its chemical characteristics, energy content and its abundance; yet its potential as a marine diesel fuel is a relatively uncharted area, says Peter Normark Sørensen, with Mærsk Oil Trading, the Mærsk Group’s oil buying arm.
Shell to build LNG units in Gulf Coast and Great Lakes regions; two additional LNG for transport corridors in North America
March 05, 2013
Shell and its affiliates will build two additional small-scale natural gas liquefaction units to provide liquefied natural gas (LNG) fuel for marine and heavy-duty on-road customers in North America. Pending final regulatory permitting, these two new liquefaction units are expected to begin operations and production in about three years.
These two units will form the basis of two new LNG transport corridors in the Great Lakes and Gulf Coast regions. This decision follows an investment decision in 2011 on a similar corridor in Alberta, Canada. (Earlier post.) Shell is also working to use natural gas as a fuel in its own operations.

Siemens, together with the Norwegian shipyard Fjellstrand, has developed a battery-electric car ferry, the miljøferge (environmental ferry) ZeroCat. The 80-meter vessel can carry up to 120 cars and 360 passengers. From 2015 onward, it will serve the E39 route between Lavik and Oppedal, across the Sognefjord. The ship’s batteries will be recharged in the breaks between crossings, a procedure which only takes 10 minutes.
The vessel currently serving this route uses on average one million liters (264 thousand gallons US) of diesel a year and emits 570 metric tons of carbon dioxide and 15 metric tons of nitrogen oxides. The electrically powered ferry was developed for submission to a competition organized by Norway’s Ministry of Transport. As a reward for winning the competition, the shipping company Norled has been granted the license to operate the route until 2025.
