A report from the UK's Public Accounts Committee claims that clean-up costs at the Sellafield nuclear reprocessing field have risen by £2.5bn in the last year. Julian Turner analyses the complex decommissioning process and asks why the mammoth project continues to be beset by delays.
GE and Miahona, a subsidiary of the Arabian Company for Water and Power Development, have signed a memorandum of understanding (MOU) to facilitate a reliable water supply in Saudi Arabia through the deployment of wastewater treatment technology.
The project is based on a gradual introduction of hydrogen-powered fuel cell buses and aims to set up bus fleets with fuel cell vehicles and the necessary infrastructure.
Flights will begin after official approval has been received from the ASTM (American Society for Testing and Materials) allowing the use of jet fuel produced using Neste Oil's NExBTL technology. This is expected to take place in spring 2011.
The bus is fitted with an electric-motor hybrid system powered by batteries and fuel cells, and is fueled with high-pressure hydrogen gas. During operation, the vehicle does not emit carbon dioxide, said to be a cause of global warming, or any other atmospheric pollutant such as nitrogen oxide; it is both highly energy-efficient and very quiet.
The American electricity grid is a century old. There are approximately 157,000 miles of high voltage electric transmission lines in the U.S.. Since 1990, electricity demand has increased 25 percent, but construction of power plants has decreased 30 percent. As the Department of Energy (DOE) states, the biggest challenge for electric distribution is "responding to rapidly changing customer needs for electricity." Enter a smart grid.
