Sentences with phrase «to grow the biomass»
The phrase "to grow the biomass" means to increase the amount of living matter (such as plants or bacteria) that can be used for various purposes, like producing fuel, food, or materials. Full definition
At a slightly higher price farmers would start specifically growing biomass for sequestration purposes.

For example, growing biomass takes CO2 out of the atmosphere, while burning it releases the gas again.
You are also competing with the food chain because land that could have been used to grow food to eat is instead used to grow biomass for a power plant.
They exclude it based on the theory that this release of carbon dioxide is matched and implicitly «offset» by the carbon dioxide absorbed by the plants growing the biomass feedstock.
This land could be used to grow biomass crops to be used for bio-fuels.
However, growing biomass soon in well - selected places with increased irrigation or fertilization could support climate policies of rapid and strong emission cuts to achieve climate stabilization below 2 degrees Celsius.
They exclude it based on the assumption that this release of carbon dioxide is matched and implicitly offset by the carbon dioxide absorbed by the plants growing the biomass.
Similarly, bio-derived fuels could be an abatement option, but only if it can be ensured that upstream emissions — in particular, land use change while growing biomass — does not impact wider potential savings.
As is the case with biofuels, there is also the significant risk that inappropriately applied incentives to encourage biochar might increase the cost and reduce the availability of food crops, if growing biomass feedstocks becomes more profitable than growing food.»
While smaller farms grow biomass for energy alongside food crops, grain elevators at large organizations become refueling stations.
However, growing biomass soon in well - selected places with increased irrigation or fertilization could support climate policies of rapid and strong emission cuts to achieve climate stabilization below 2 degrees Celsius.
It is used in power generation, primarily for cooling thermal power plants; in the extraction, transport and processing of fuels; and, increasingly, in irrigation to grow biomass feedstock crops.
The best geoengineering that I can think of is the process of pumping CO2 from the air by growing biomass, using pyrolysis to generate bio-oil and biochar from the biomass, then returning the biochar to the soil where it aids in maintaining fertility while sequestering carbon for centuries, AKA terra preta.
It's estimated that to make a substantial difference to global warming huge expanses of land would have to be given over to growing biomass crops.
This risks depriving poor people of food crops and destroying ecosystems as swathes of land are converted to growing biomass for energy.
From the atmosphere's point of view, growing biomass to burn in a power plant and using the electricity to move a car avoids 10 tons of carbon dioxide emissions per acre, or 108 percent more emission offsets than ethanol.
In particular, these models love a technology called «bioenergy carbon capture and sequestration (BECCS)» because it has negative emissions — you grow biomass, harvest it and burn it for electricity, and then store the pollution underground.
The IPCC carbon capture and storage report suggests that growing biomass and burning it with carbon capture might work, to some extent.
On the one hand, fossil fuel inputs for growing the biomass will likely be much lower than for corn.
Devoting land to growing feedstock for liquid biofuels, or growing biomass for generating electricity, augurs the greatest potential energy sprawl of the major energy alternatives under discussion.
Ironically moves towards geoengineering may close down agroecological options: CDR [Carbon Dioxide Removal] approaches such as BECCS [Bio-Energy with Carbon Capture and Sequestration] would grab even more peasant lands to grow biomass feedstocks (causing suffering); sulfate aerosols may disrupt the very tropical climates that peasant farmers rely on (causing suffering?)
You grow biomass, which takes CO2 out of the air.
A variant of the idea in which you grow the biomass and burn it in power stations fitted out for carbon capture and storage does even better: 0.69 W / m ² by 2050 and almost 2W / m ² by 2100 (For the longwave calculations, the radiative forcing depends on how long the programme has been going on.
To make biomass it would require the use of Diesel to power the harvesting equipment etc. that is needed to grow the biomass, then harvest it and then transport it.
