According to Blank and Turner the study is one of the first to examine grassland fields already producing biomass for biofuels
While previous studies suggest corn is a more profitable biofuel crop than grasses and other types of vegetation the new findings indicate grassland fields may represent an acceptable tradeoff between creating biomass for bioenergy and providing habitat for grassland birds.

#Leaked EU documents rank biofuel emissions higher than crude oil European union politics website Euractive has gotten its hands on official EU data reporting that many biofuel crops release more carbon dioxide than crude oil,
The numbers were intended for release in the spring when the EU presents new proposals on biofuels,
The European commission has defended long biofuels, despite dissent from Greenpeace and other environmental organizations. Its current biofuel roadmap demands that at least 5. 75%of all energy sold on the market of any member country be biofuel
boosted to 10%by 2020. However, also in the biofuel directive is that biofuel production should be sustainable,
and the new numbers suggest that it is not. The leaked data present higher carbon costs for biofuels because, for the first time,
the analysts incorporated the effects of indirect land use change (ILUC). ILUC is the rise in emissions
when forests and wetlands are destroyed to clear land to grow biofuel crops. And with ILUC added to the mix, it looks like some top biofuel crops are worse for the environment, in terms of carbon emissions, than crude oil.
The EU's default value for measuring carbon efficiency for oil from tar sands is 107g CO2 equivalent per megajoule of fuel (CO2/mj.
Meanwhile, crude oil's efficiency value is 87. 5g CO2/mj. Here are the data (g CO2/mj) from the EU documents,
incorporating ILUC, for various biofuel crops, thanks to Euractive: Palm oil-105g Soybean-103g Rapeseed-95g Sunflower-86g Palm oil with methane capture-83g Wheat (process fuel not specified)- 64g Wheat (as process fuel natural gas used in CHP)- 47g
Corn (Maize)- 43g Sugar cane-36g Sugar beet-34g Wheat (straw as process fuel in CHP plants)- 35g 2g Ethanol (land-using)- 32g 2g Biodiesel (land-using)- 21g 2g Ethanol

The extraction of the hydrogen from the diesel fuel happens through autothermal reforming, a catalytic reaction in
which the diesel fuel is decomposed into hydrogen, steam, carbon dioxide, and carbon monoxide. The CO is converted then to CO2
It didn escape their notice that the extraction of hydrogen from the diesel fuel releases CO2 directly into the atmosphere. ctually all carbon in the diesel is converted to CO2,
fuel consumption is 80 percent lower, and consequently, the produced amount of CO2 is decreased by 80 percent,

Such advances might eventually make solar power cheaper than fossil fuels, even without Semprius technology. But silicon-based solar power is not yet there,
Besides a small rise in the price of natural gas and slightly cheaper coal, the weather played the biggest role in in pushing up emissions,

#Why Coconuts Could Be the Hydrogen Storage Material of the Future Hydrogen is a potential renewable fuel
The hope is that it could also be distributed using the same global network of liquid fuel transport that moves petrol around the planet.
Hydrogen gas has a poor energy density by volume compared to petrol. In fact, there is at least 60 percent more hydrogen in a liter of gasoline then there is in a liter of pure liquid hydrogen.
In other words hydrogen will always require bigger tanks. So finding ways to store more of it is a huge challenge.
Now Viney Dixit and buddies at the Hydrogen energy Center of Banaras Hindu University in India say they have discovered that carbonized coconut flesh is particularly good at this task.

When it opens next year it will have the capacity to produce 650000 kilograms of hydrogen a year the energy equivalent of 650000 gallons of gasoline.
Hydrogenics which has supplied electrolyzers for many of the biggest projects in Germany is designing a 40-megawatt system that will produce the equivalent of 4. 3 million gallons of gasoline a year.

Of the 117 bcm of natural gas that China produced in 2013, only 0. 2 bcm came from shale.
If China is going to meet its goals for using natural gas, it probably will have to rely more on imports.
