Effort to Produce a Gallon of Tar Sands Oil Can Send an EV Over 30 Miles
A new report published over at Hybrid Cars reveals that the energy it takes to produce just one gallon of gasoline from the Canadian tar sands could send EV’s or plug-in hybrid vehicles for more than 30 miles, exposing the intensive and inefficient process of oil-refining. The report shows that each 42-gallon barrel of oil, of which only about half is actually refined into motor-grade gasoline, requires about 301 kWh of electricity to produce. A generous estimation puts the total amount of refined petrol at 23.4 gallons from each barrel, which places the electricity cost of each barrel of oil at a little less than 13 kWh. But, if instead that energy were used in a plug-in car, you could drive about 37 miles without emitting a single whiff of carbon dioxide.
Chances are, your performance car is going to be in insurance group 50. This means you’re going to be paying more than most for your cover but if you search around enough you can avoid getting truly stung.
Alaskan Project May Lead to Flywheel Storage Technology Uptick, Says Beacon
Beacon Power LLC foresees that an Alaskan island’s utilization of its flywheels to store energy from a power plant will pave the way for wider application of the technology to help reduce fossil fuel use. The 165-kilowatt flywheels project to store energy from TDX Power Inc.’s hybrid wind and diesel power plant on Saint Paul Island in the Bering Sea is expected to reduce fuel use by 30 percent, says Beacon. The Massachusetts-based Beacon will use 2,500- pound rotating carbon fiber cyclinders to store energy. The kinetic energy produced by the cylinders will then be converted into electricity and transferred to and from the grid to absorb sudden surges in supply or demand.
China Cuts 2020 Shale Gas Target in Half
China quietly reduced its 2020 goals for shale gas – a goal that was so ambitious that it was met with skepticism both inside and outside China. The initial goal of the Asian powerhouse was to ramp up from zero commercial production of shale gas to 60 to 80 billion cubic meters by the end of the decade. Now, the country is stepping back a bit, cutting the target to 30 billion and combine it with coal bed methane (CBM).
Tepco Admits Failure of Fukushima Ice Wall
TEPCO administrators said earlier this week that the section of ice wall between Fukushima Dai Ichi’s unit #2 turbine building and the cable tunnel – which was estimated to hold up to 6,000 tons of highly radioactive water- was not working. Although Tepco already had injected more than 400 tons of ice and dry ice to freeze contaminated water, the temperature did not fall low enough and the strategy did not work. The company now plans to start utilizing fillers, come mid-September, to slow the flow of water in the unfrozen section. They believe that doing so will enable it to freeze.
