Biofuel is a type of fuel that is made from organic materials, like plants or waste, instead of fossil fuels.
Full definition
The two companies will combine their proprietary technologies to jointly develop projects for the production
of biofuels in other countries.
These findings have significance for human health but also
for biofuels production, since the same sugars can be fed to yeast to generate ethanol and other liquid fuels.
Introduce carbon accounting from 2020 — meaning a full picture of the climate impacts of
biofuels production.
Put a cap on land - using crops
in biofuels at 6 % of fuel use.
Social groups were unhappy about making advanced
biofuels from food sources, such as corn, or on land used for food crops because a growing population will need more food.
The researchers suggested these species could only be safely used
as biofuels within their current ranges.
We shouldn't put the taxpayer on the hook for broken promises, and we should create a more level playing field for
advanced biofuels.
Even though many outstanding research questions remain unanswered, we now have the outline sketches of what a successful, low - carbon
biofuels industry should look like.
Environmental groups, worried about the sources of new fuels, rejected proposals to
make biofuels out of trees.
The first in question is the world's first industrial scale facility to
produce biofuels from municipal solid waste.
But making that dream a reality could harm local environments and would require developing new technology to harvest, process and convert such plant material
into biofuels such as ethanol.
The neutrality assumption is not valid because it ignores the transient, but decades to centuries long, increase in CO2 caused
by biofuels.
First - of - a-kind
biofuels plants cost hundreds of millions of dollars, and new - design nuclear reactors or coal - fired power plants that incorporate carbon capture and sequestration cost billions.
According to the researchers, these principles (as well as four more outlined in the paper) are enough to begin guiding sound policy decisions for producing
sustainable biofuels.
Even after decades and millions of dollars in public and private of investment, production of
algae biofuels has failed to become commercially viable.
But the more research that's done on
liquid biofuels, the less attractive they become.
«There's substantial disagreement on possible future yields of energy crops,» he said, as well as questions on the consequences of
growing biofuels on water supply.
Important emission reduction options in the transport sector
include biofuels, electric vehicles and efficiency standards.
Plant - derived
biofuels such as ethanol offer renewable - energy alternatives to fossil fuels.
Those searching for alternatives to oil and natural gas often have trouble acknowledging the relative physical limitations of other sources, particularly
biofuels like ethanol.
Her plan to fill the gap relies on
more biofuels, buying in green power and «credits» from abroad - everything but wind and solar.
And he asserts that the science puzzle of how to
create biofuels using organisms is largely finished.
This project has generated interest from visiting schools eager to learn
about biofuels.
Better air traffic management / operational improvements; new technologies and standards for more efficient aircraft; lower -
carbon biofuels — all, in principle, can help close the gap.
By increasing fuel economy, producing
better biofuels, and investing in electric vehicles, we can cut our oil use, reduce global warming emissions, and clean up our air.
Staff is developing low - CI fuel projections that take into account the effect of petroleum prices on the production of
biofuels which will result in low, medium, and high projections.
Likewise,
if biofuels cause other land to be cleared, there will be additional flow into the bathtub.
The goal of
biofuels research is to make the math work in a way that results in a genuinely low - carbon energy source.
The researchers hope the process leads to economically viable production of
aviation biofuels in the next five years.
This includes the increased cost of the fuel, caused by higher prices at the pumps, and also the need to fill tanks more often
because biofuels contain less energy.
When biofuels are burned, they reduce the amount of fossil carbon that would flow into the bathtub.
But later in the century, carbon - removing techniques, such as
burning biofuels while capturing their carbon emissions or developing carbon - sucking machines, may be feasible.
The report also suggests that balancing the potential pitfalls and benefits of
biofuels requires a new approach to energy planning.
Governments
promote biofuels as renewable, carbon - neutral resources that serve to reduce CO2 emissions.
«It will begin to address the nation's challenge for the production of clean,
domestic biofuels that can help replace crude oil,» he said.
There are two key reasons
many biofuels are more polluting than fossil fuels.
