Abstract International maritime shipping—powered by heavy fuel oil—contributes 2.5%, 12%, and 13% of global anthropogenic CO2, SO2, and NOx emissions, respectively. The direct electrification of vessels has been underexplored as a low-emission option despite its considerable efficiency advantage over electrofuels such as green hydrogen and ammonia. Previous studies of ship electrification have relied on outdated battery cost and energy density values and have incorrectly assumed mechanical space to be a fixed technical variable. We show that with near-future battery prices of $100 kWh-1 the electrification of intraregional trade routes of less than 1,000 km is economically feasible with minimal impact to ship carrying capacity. Projected declines in battery price to $50 kWh-1 could improve this range to 5,000 km. We describe a pathway for the battery electrification of containerships within this decade that electrifies over 40% of global containership traffic, reduces CO2 emissions by 40% for US-based vessels, and mitigates the health impacts of air pollution on coastal communities.

ABSTRACT Oil from the Sea Empress spill in February 1996 contaminated more than 120 miles of South Wales coastline, including rocky shores, sand and shingle shores, mudflats, and salt marsh. Some aerosol sprays also contaminated some maritime cliff along wave-exposed coasts. Some areas of shore, including areas with a high nature conservation value, were heavily oiled. Although much of the affected shore lies on the open coast and is exposed to wave action, large amounts of oil remained on the shores for many months, becoming buried and bound with sediments, percolating deep into cobble and shingle shores, and pooling behind rock features. Oil persistence has been greatest on sheltered shores, particularly where heavy fuel oil stranded. Cleanup activities on these shores have included the use of dispersants, high-pressure washing, low-pressure deluge, trenching, and berm relocation. Numerous studies of the effects of the oil and the cleanup techniques on the intertidal and coastal communities are being undertaken by biologists from various organizations. This paper presents a summary of the results so far.

Electric Vehicles (EVs) are gaining momentum due to several factors, including the price reduction as well as the climate and environmental awareness. This paper reviews the advances of EVs regarding battery technology trends, charging methods, as well as new research challenges and open opportunities. More specifically, an analysis of the worldwide market situation of EVs and their future prospects is carried out. Given that one of the fundamental aspects in EVs is the battery, the paper presents a thorough review of the battery technologies—from the Lead-acid batteries to the Lithium-ion. Moreover, we review the different standards that are available for EVs charging process, as well as the power control and battery energy management proposals. Finally, we conclude our work by presenting our vision about what is expected in the near future within this field, as well as the research aspects that are still open for both industry and academic communities.

The most popular method of controlling sulfur dioxide (SO2) emissions in a steam turbine power plant is a flue gas desulfurization (FGD) process that uses lime/limestone scrubbing. Another relatively newer FGD technology is to use seawater as a scrubbing medium to absorb SO2 by utilizing the alkalinity present in seawater. This seawater scrubbing FGD process is viable and attractive when a sufficient quantity of seawater is available as a spent cooling water within reasonable proximity to the FGD scrubber. In this process the SO2 gas in the flue gas is absorbed by seawater in an absorber and subsequently oxidized to sulfate by additional seawater. The benefits of the seawater FGD process over the lime/limestone process and other processes are; 1) The process does not require reagents for scrubbing as only seawater and air are needed, thereby reducing the plant operating cost significantly, and 2) No solid waste and sludge are generated, eliminating waste disposal, resulting in substantial cost savings and increasing plant operating reliability. This paper reviews the thermodynamic aspects of the SO2 and seawater system, basic process principles and chemistry, major unit operations consisting of absorption, oxidation and neutralization, plant operation and performance, cost estimates for a typical seawater FGD plant, and pertinent environmental issues and impacts. In addition, the paper presents the major design features of a seawater FGD scrubber for the 130 MW oil fired steam turbine power plant that is under construction in Madinat Yanbu Al-Sinaiyah, Saudi Arabia. The scrubber with the power plant designed for burning heavy fuel oil containing 4% sulfur by weight, is designed to reduce the SO2 level in flue gas to 425 ng/J from 1,957 ng/J.
