Analysts and commentators are quick to point out that fossil fuels will power maritime equipment, and indeed dominate the fueling marketplace, well into the future. However, they will do so alongside new fuels, and new technologies, that will be introduced to the maritime sector in the coming years. In its September, 2023 report “Beyond the Horizon: View of the Emerging Energy Value Chains”, the American Bureau of Shipping (ABS) explains that, “During the recent 80th meeting of the Marine Environment Protection Committee (MEPC 80)…

If towboats and barges hurtled passed the average American on their way to work every morning, the industry would be better known. If commuters had to deal with failed locks the way they have to deal with congested freeways, political support for the river industry’s infrastructure would be easier to come by. Instead, towing vessels and their crews go about their work in relative obscurity. The general public sees towboats and barges as historic relics from Sam Clemens’ time and less so an integral part of the modern American economy.

The Lure of the Electric Drive

By Stuart C. Karon and Dr. In the September 2002 issue of Maritime Reporter and Engineering News, a detailed discussion was featured on the advantages of future High Temperature Superconductor (HTS) machinery for propulsion of electric drive ships. • Motors A 5-MW 230-rpm machine for the U.S. Navy's Office of Naval Research (ONR) is undergoing factory tests. ONR is now funding the next step - design, fabrication and factory testing of a 36.5-MW 120-rpm machine to prove the technology at full-scale for warships. • Generators Development of HTS generators has also leapt ahead with the initial production of 10-MVAR synchronous condensers for utility voltage adjusting service. These condensers are very similar in design and operation to 10-MW, 1,800-rpm generators.

America's Western River: A Unique Security Challenge

Since 9-11 all facets of the media have combined to focus national policy makers, in and out of government, along with the general public on the asymmetric terrorist threat facing the United States and its global trading partners. Lengthy newspaper articles or Op-ed pieces, documentaries on television such as The Learning Channel and the Discovery Channel, along with talk radio banter have spotlighted multiple areas of concern. These have included airplanes, tanker trucks, critical infrastructure and the country's bustling seaports such as New York and Los Angles. The maritime nexus in particular has received a lot of attention as over 90 percent of the nation's commerce travels by water.
