American Samoa’s Power Authority (ASPA) is investigating windpower and OTEC [cached] to replace 13 million gallons of diesel fuel per year, according to Radio New Zealand. Fonoti Perelini Perelini, chief operations officer of ASPA, says a consultant is submitting a report to the Department of the Interior and then to Congress for funding purposes for OTEC. He also says the consultant from the US believes OTEC holds the most potential of any another… Continue reading
Danish researchers at the Technical University of Denmark may have taken an important step towards hydrogen based transport systems. In a news article they say that they store the hydrogen as ammonia absorbed in sea-salt tablets [cached]. “Within the tablet, hydrogen is stored as long as desired, and when hydrogen is needed, ammonia is released through a catalyst that decomposes it back to free hydrogen. When the tablet is empty, you merely… Continue reading
David Gårsjö and Mårten Niklasson of Royal Institute of Technology Chemical Engineering and Technology, Sweden, recently presented a report on Safety Issues with Hydrogen as a Vehicle Fuel (PDF 1.8 Mb) at a hydrogen fuel cell buss seminar which I attended. It is a very interesting report. The English extended abstract can be found on pages 100-113 in the PDF file. The conclusion starts with the following: “Compared with other fuels, hydrogen is… Continue reading
Octane fuel cells Researchers at Pacific Northwest National Laboratory have invented a fuel cell that will run on pure Octane (C8H18), emitting only water and carbon dioxide as exhaust. The fuel cell promises a high efficiency, about 50%, which it achieves by making the system a combined hydrogen reformer and fuel cell. The waste heat from the fuel cell helps power the reformer. The system needs high temperature to operate so… Continue reading
The Jamaica Gleaner reports that Professor Al Binger of the University of the West Indies is casting doubt over the viability of a LPG gas terminal which is being built on Jamaica. The director of the University of the West Indies Centre for Environment and Development (UWICED) is suggesting that the Government should instead explore another option, the Ocean Thermal Energy Conversion (OTEC). Professor Binger told The Gleaner: “I think LNG is swapping monkey… Continue reading
William Avery, the lead author of Renewable Energy from them Ocean, A guide to OTEC published an article on IOA’s web site about The influence of recent low interest rates on the estimated prices of OTEC fuels [cached]. This was written last year, but only now came to our attention.
Introduction: An important goal of OTEC commercial development is to produce vehicle fuels that can be a cost-effective, sustainable alternative to gasoline. If… Continue reading
