Researchers from Aston University explain that while operating measures and fuel alternatives are suitable in the short-term to meet a reduction in carbon emissions from shipping, as the use of fossil fuels tapers off, the long-terms solution appears to reside in wind-assisted ships. Consequently, this study aims to identify viable solutions that could reduce emissions, focusing on three prominent technologies, namely sails, rotors and kites. Click here to read more ..
Researchers from the School of Naval Architecture, Dalian University of Technology, China Ship Design and Research Center Ltd have published a summary of WASP technologies amidst increasing momentum to reduce carbon emission at the forefront of international opinion and the subsequent changes in the shipping industry that can cause transformation of the entire industry chain, from ship design to maritime operations. Research team led by Yunlong Wang, have explained that WASP technology is an excellent option for shipowners to adapt to the transition. Numerous studies in academia and industry have quantified the technical potential for fuel savings from wind energy and have examined the impact of wind speed and direction, trade patterns, geographic regions, seasonal effects and route optimization. The results consistently show that WASP technology has a large potential to improve the energy efficiency of ships, save energy and reduce emissions. Click here to read more
The International Council on Clean Transportation just released its latest white paper on potential of using Hydrogen Fuel Cells and Wind-Assisted Propulsion on three ships: a 57,000 deadweight tonne (dwt) coastal dry bulk carrier sailing in China, a 69,000 dwt ore and coal carrier sailing the North American Great Lakes, and a 7,570 dwt cement carrier in northern Europe. This study investigates the potential of both liquid and compressed hydrogen fuel cells to replace fossil fuels for bulk carriers, including when paired with wind-assisted propulsion in the form of rotor sails.

A team of scientists have released an intriguing study on harnessing OTE in the Pacific n the Journal of Geosciences. Hyeon-Ju Kim, Ho-Seung Lee, Seung-Taek Lim and Michael Petterson have authored "The Suitability of the Pacific Islands for Harnessing Ocean Thermal Energy and the Feasibility of OTEC Plants for Onshore or Offshore Processing"
..."An engineering principle, termed Rankine cycle power generation, can use the thermal gradient to generate power. Whilst at the moment OTEC is not a large-scale commercial reality, a number of organizations are developing small-scale OTEC plants, both land and sea-based, with the vision that, one day, the plants will become large enough to attract commercial interest..."
