This write-up focuses on combustion of biomass to produce heat and power, recognizing that many of the feedstocks for biofuels are the same materials that are burned for energy generation.
Utility-scale plants operate at a range of efficiencies, though most new proposals will be about 24% efficient (the very largest plants claim to be around 29% efficient). The average capacity of the biomass burners currently proposed is about 38 MW, but there are more than 30 plants being built in the 50 – 110 MW range, and an as-yet-undocumented number of biomass co-firing proposals for coal plants. The vast majority of the over 115 biomass electricity generating plants under construction or in the permitting process plan on burning wood as fuel. Using biomass for heating is fundamentally more efficient than using it to drive a turbine for electricity generation, meaning that fuel demand per unit useful output is reduced.
But biomass energy for thermal and electrical generation do share many of the same problems as utility-scale power generation. Whatever the size of the biomass burner, if it is fueled by increased forest harvesting, its net carbon emissions will be greater than a comparably sized fossil fueled facility, requiring years to multiple decades for forest regrowth to erase the carbon debt created by removing trees. Some biomass burners are fueled by wood pellets, which burn more cleanly and efficiently than the raw green wood typically burned at utility-scale biomass plants. Burning wood emits large amounts of air pollution, and existing biomass plants in the US are generally quite old and lacking modern emissions controls. Emissions of pollutants from burning any fuel are a function of the emissions inherent to combustion, and the efficacy of emissions controls.
To give an idea of how much pollution a biomass plant can produce, here are emissions numbers from the air permit and application documents for the proposed 100 MW Gainesville Renewable Energy Center (GREC) in Florida, contrasted with air permit numbers from the Pioneer Valley Energy Center (PVEC), a 431 MW gas and diesel plant proposed in Westfield, Massachusetts. Burning one ton of green wood emits a little more than one ton of CO2 (assuming wood has 45% moisture content, an industry standard).
Notably, the state of Massachusetts completed a similar multi-stakeholder review in about 7 months.
Concurrently, EPA’s new boiler rule sets emission limits on particulate matter, carbon monoxide, hydrochloric acid, dioxins, and mercury, for commercial and industrial boilers that emit more than 25 tons of specified hazardous air pollutants per year. In several states, particularly Ohio, coal-burning power plants are blending wood with coal to meet state renewable energy mandates.
Biomass power benefits handsomely from its classification as renewable energy, which makes it eligible for a raft of federal, state, and ratepayer subsidies and tax breaks. Renewable Energy Credits – Burning biomass generates Renewable Energy Credits (RECs) under current carbon accounting rules and renewable energy definitions. Investment Tax Credit or Section 1603 Treasury Grants– Instead of taking the production tax credit, biomass developers can choose an investment tax credit (ITC) created under the 2009 American Reinvestment and Recovery Act (ARRA) as amended.
In the absence of a federal renewable energy mandate states have stepped into the void with renewable energy (portfolio) standards and greenhouse gas reduction initiatives that set goals and provide incentives for the development of renewable energy (see a list of state and federal programs here). Massachusetts stands out as the one state that has conducted a transparent, independent review of the science on the renewability and carbon neutrality of tree-burning biomass. Despite requiring clearcutting of millions of forest acres per year, the Department of Energy declines to assess carbon pollution impacts from a biofueled economy. False claims that wood pellets are climate-friendly misrepresent Forest Service science and are an ominous sign for US forests.
Legislating that bioenergy produces no carbon pollution makes as little sense as legislating that climate change does not exist.
We all know burning trees drives climate change, but Senate legislation now being considered would dictate that burning more trees does not increase carbon pollution.
Biomass are organic materials of byologic origin produced from animal or plant or or no fossilized sources, which emplyment in the energetic field consists in its use in the form of fuel, to replace or supplement natural or fossil fuels such as hydrocarbons, carbons e natural gas. Regarding biomass coming from plans sources, they're products a product of CO2 emissions globally null because carbon dioxide emitted is the same that plants absorbed to grow.
From the fermentation of some plants such as the sugar cane or others, it's possible to obtains biofuels, in particular it's possible to obtain high octane fuels for uses in "gasoline" engines and fuels similar to gas oil for diesel engines (biodisel), over, of course, all the other applications where fuels of fossil source are used.
With regard to the ethanol, calorific value is about 40% lower than gasoline one, but it presents a numbr of di octane higher compared to this one. Who is an Expert in Energy Management (EGE) and what is his role?What is the difference between a photovoltaic system and a solar thermal system?Why choose ARGO as name ? You may be wondering if growth in renewable energy jobs is an indicator of investment opportunities.
Here's my nominee for stat of the day: The American economy added over 8 million jobs from January 2011 to June 2014. The job statistics only include employment figures for power generation, which excludes jobs in transmission, distribution, the processing of fuels, construction of new facilities, and installation of distributed generation systems such as wind and solar.
Of course, renewable energy still represents the smallest aggregate workforce in America's power generation sector, which makes it easier to achieve eye-popping growth (i.e. That's not too surprising considering NextEra Energy added over 2,500 MW of effective wind power capacity during that time period. In other words, NextEra Energy is perhaps the perfect embodiment of power sector job trends in the last several years -- and it has enjoyed amazing performance as a result. Is it really this easy?After a little retrospective analysis, there certainly appears to be a correlation between trends in renewable energy jobs and NextEra Energy's performance, but good luck trying to use the relationship as a predictor of future results.
When it comes to wind capacity, investment decisions are heavily influenced by government incentives.
Finally, job creation ebbs and flows from month to month or year to year, even with a healthy stream of generation projects in the pipeline.
What does it mean for investors?Investors can watch growth in renewable energy jobs to glimpse industry trends, but job creation is a result of increased interest and investments by companies, which itself is affected by numerous factors, ranging from tax credits to air pollution regulations. So although it appears that NextEra Energy's performance is correlated with renewable energy job creation, investors are better off keeping an eye on the factors affecting the company's investment decisions.

Fermentation: There are several types of processes that can produce alcohol (ethanol) from plants, especially corn. Conversion: Today, biomass can be converted into gas and liquid fuels by heating or adding chemicals to the biomass. February 4, 2013 by Sara Aaserud Leave a Comment We’re in the midst of finishing up some feasibility studies for ground source heat pump (GSHP) or geothermal heat pump (GHP) technology, so I figured that now would be good time to give you some basic things to think about when considering GSHPs.  In this post I’m going to cover some important design considerations, and in another post next week I’ll cover some important things about economics and installation. Energy transfer to and from the ground occurs using fluid that flows through a series of pipes buried underground.  The ground does a good job at transferring energy to and from the ground loop, but heat pumps within the building can also add or reject additional heat from the pipe loop as needed to meet building temperature requirements. Just as a side note: don’t confuse GSHP technology with geothermal power, which uses hot water or steam from deep inside the earth to produce electricity. So why does this balancing act matter?  Well, heat pumps operate best within a certain range of temperatures.  Once the ground surrounding the loop gets too hot or too cold, so does the liquid within the pipes.
If your facility contains a boiler room right now, that too is contributing its fair share of heat to the building’s envelope.  Once you install a GSHP system, that heat gain isn’t going to be there anymore, so your GSHP system will have to be sized accordingly. Improperly-sized GSHP will likely operate just fine for a few years until the load imbalances catch up with them.  Then the heat pump efficiencies will suffer and the system probably won’t operate as designed. Heat pump efficiency – More efficient heat pumps require less ground loop to get the same job done.  They also use less electricity, which means that your operating costs will be lower. Want some more resources on GSHP technology?  Check out the International Ground Source Heat Pump Association (IGSHPA)’s website FAQ here.
Le chien de garde a confirme ses conclusions et accordee les modifications permis du projet environnemental qui lui permettrait d’operer avec une augmentation des emissions. On dit que les limites etaient encore bien dans les lignes directrices proposees par le gouvernement. There are currently 13 proposals nationally for liquid biofuels plants that will use wood as feedstock, and more than 40 recently built or proposed wood pellet plants. Here’s a photo of the McNeil biomass plant in Burlington, Vermont, showing the size of the woodpile, and the piles of logs awaiting chipping as fuel.
An unknown amount of wood will be required for co-firing in coal plants, with estimates for Ohio alone, where the State’s Public Utilities Commission has approved over 2,100 MW of biomass power, of about 20 million tons of wood required for fuel annually. Proponents argue that since this material will end up as CO2 in the atmosphere anyway, why not use it to generate some power in the meantime?
As shown by the Manomet Study, increasing forest harvesting to provide biomass fuel unambiguously and dramatically increases carbon emissions, relative to fossil fuels, both because wood is such a high carbon, low efficiency fuel, and because cutting forests for fuel decreases their ability to take carbon dioxide out of the atmosphere. And in any case, simply re-growing biomass that has been cut and burned doesn’t necessarily reduce net energy emissions compared to simply continuing to burn fossil fuels, because using biomass to generate energy emits a lot more carbon than using fossil fuels, while diminishing the ability of forests to sequester carbon for decades (see the section on carbon emissions for a more detailed explanation of why biomass facilities are not renewable or carbon neutral in any meaningful sense of the terms). In general, biomass burners operated for heat, or for combined heat and power, are also significantly smaller than utility-scale electrical generating plants, which demand hundreds of thousands of tons of wood a year.
In 2004, Middlebury College in Vermont conducted a wood fuel sustainability study that concluded that their proposed (now built) 2 MW combined-heat-and-power gasification plant would require 40,000 acres of forest to provide fuel, once current sawtimber and firewood demands on the forest were taken into account. This is because wood pellets are generally made of the white, debarked trunkwood of larger trees, which has been dried to produce optimum combustion. EPA recently fined two plants in California’s Central Valley for failing to install emissions controls and otherwise flaunting responsible practice.
The largest biomass plants are small in comparison to an average coal plant, and it is generally not cost-effective for biomass plants to install the most effective control technologies. Carbon dioxide from new standalone facilities will be about 55 million tons per year, or 78 million tons if preliminary estimates of co-firing are included.
The agency is now embarking on a review to determine how to account for carbon emissions from biomass electricity generation. The definition of biomass as renewable and carbon neutral is integral to the eligibility of biomass facilities to receive Renewable Energy Credits (RECs).
The ITC, reimburses 30 percent of plant development costs if the plant begins construction by the end of 2011. A typical 50 MW biomass power plant would avoid payments of $58 million over the five year period starting in 2012, a savings that would increase to $110 million for the 2021 – 2025. Department of Agriculture, that provides matching payment for up to $45 per dry ton (about $25 per green ton) of fuel. Swept ahead by a flood of state and federal tax breaks and financial incentives, and shielded by the inaccurate definition of biomass energy as carbon neutral and renewable, these goals have produced a nationwide onslaught of proposals to build wood-burning biomass power plants; more than 115 today and climbing. Therefor used in a motor, on one side increase consumptions at cause of the need of mixture air - combustibile rich of hetanol compared to gasoline one, the other it's make possible the use of higher compression rates with benefits benefici on the performance of the same engine.
Yet despite the shale gas boom, the nation's electric power generation sector lost 5,800 jobs in the same period. A net loss of 5,800 jobs doesn't mean all energy sources saw declining employment, although that would have been true if it wasn't for renewable energy. The Production Tax Credit, or PTC, provides 2.3 cents per kWh of electricity produced for the first 10 years of operations, but only if construction began during a year in which the PTC was active. There are grid-scale solar projects in operation and in development, but most solar energy will likely come from distributed systems. Meanwhile, data reported by the Bureau of Labor and Statistics are better suited for tracking trends from traditional power generation occurring in maintenance-intensive, centralized power plants.

With this simple but very effective technology Biomass can be a cost effective solution compared with traditional fossil fuel boilers.
During a process called photosynthesis, sunlight gives plants the energy they need to convert water and carbon dioxide into oxygen and sugars.
With the advance in technologies, several alternatives and perhaps more efficient energy conversion processes, such as gasification, and anaerobic digestion are used.
The most common process involves using yeast to ferment the starch in the plant to produce ethanol. The gas and liquid fuels can then be burned to produce heat or electricity, or it can be used as a fuel for automobiles. Over time the heat pumps simply won’t operate at their peak efficiency anymore.  As a result, they consume a lot more energy trying to get the same job done.

With certain exceptions, however, despite the variety of different types of fuel in theory, the current rapid expansion of the biomass energy sector is dependent almost entirely on forest wood.
It is worse than coal, worse than oil, and worse than natural gas, both because of the low energy to carbon ratio inherent in wood, and also because biomass facilities generally operate at considerably lower efficiencies than fossil fueled facilities. However, it is important to remember that burning emits carbon instantaneously, while decomposition takes years and even decades, and in the case of the waste wood left over from logging operations, actually builds soil carbon in the meantime. To the contrary, in every state we have analyzed, including Washington, Vermont, Massachusetts, Wisconsin and New York, the amount of slash generated by logging operations falls far short of the amount needed to feed the proposed biomass burners. These facts combined mean that thermal biomass and  combined heat and power generation represents less of a threat to forests than large-scale electricity generation plants.
The Manomet Study provided the research and modeling that showed why this is true on the ground, demonstrating that fueling even small, efficient biomass burners with whole trees increases net carbon emissions over using fossil fuels for two to three decades.
Scaled up, such a proposal would require one million acres of land to supply a 50 MW plant. Given the inputs required to create pellet fuels, the process of pellet production itself is extremely wasteful and polluting, requiring about two and a half tons of trees to produce one ton of finished pellets and emitting large amounts of particulate matter and other pollutants. The outcome of this review will greatly influence the industry’s long-term viability, but the three-year suspension of permitting means that plants will rush to be built and thus be grandfathered and exempt from carbon accounting if and when EPA reinstitutes it. True carbon neutrality, meaning that all the carbon released when trees are burned has been recaptured, would take many more decades still. Biomass plants basically go through the same permitting procedures as other facilities with regard to meeting emissions thresholds, etc; however, the Clean Air Act and other environmental legislation contain certain loopholes for biomass power facilities.
But because biomass is considered carbon neutral and renewable, burning forest wood in coal-fired power plants qualifies for renewable energy credits and helps utilities attain renewable energy goals.
Every megawatt-hour of electricity generated at a biomass plant is accompanied by a REC, which can then be sold to power providers who are obligated to purchase a certain amount of energy from renewable sources. It's strange, but true, according to data released by the Bureau of Labor and Statistics and compiled by the U.S. While electricity generation from fossil fuels (-1%), hydroelectric (-6%), and nuclear (-9%) all saw workforce reductions in the period, renewable energy generation from wind (16%), solar (201%), and biomass (20%) all saw employment gains.
But that doesn't discredit the momentum in renewable energy stocks and the relative weakness in other energy sources. The share price of the nation's leading owner of wind power has performed in lock-step with monthly wind production in the period noted above. While 27% of the company's generation capacity comes from nuclear power plants, it hasn't been tempted to reduce its exposure as other power generators have done. Zoom out further and there's no doubt that the company's long-term growth has been positively affected by over $16 billion in wind energy investments. Job creation is the result of real projects being built in the physical world, not the other way around.
You may have noticed that the final three months of a given year seem to be the industry's favorite time to build new capacity.
That makes rooftop solar providers such as SunPower and SolarCity, not power generators, the most likely beneficiaries of growth. That doesn't account for the fact that renewable energy generation typically occurs in low-maintenance, distributed systems that aren't always owned by power generators. Burning logs or wood pellets the boilers only emit the same amount of Carbon Dioxide as the plants and trees growing around us.Easy integrationBiomass produces high grade heat and can very effectively bolt on to existing heating distribution systems such as radiators. These sugars, called carbohydrates, supply plants and the animals that eat plants with energy.
Typical CO2 emissions at a utility-scale biomass plant are 150% those of a coal-burner, and 300 – 400% those of natural gas facility (click here for a more detailed explanation of carbon accounting for biomass).
In other states, including Ohio and North Carolina, utilities have been more forthright and simply admitted that biomass electricity generation means cutting and burning trees.
Middlebury College has since initiated a pilot willow-growing project, to provide fuel when the local chip supply tightens, although early results from a test-firing of the willow fuel indicate that fuel moisture is a significant problem. Pellet production, primarily for thermal biomass, is a looming threat to forests and climate as demand for pellets grows steadily, particularly in European markets. A review of the Manomet study suggests that due to a number of assumptions made in the report, actual time to achieve parity with fossil fuel emissions may be even longer than was concluded. The REC’s can be sold separately from the power itself, which is fed into the grid and becomes indistinguishable from power generated from conventional sources. With that in mind, can investors use growth in renewable energy jobs in the power sector to find better investment opportunities? That means you should focus on what factors affect capacity expansion decisions, which is what really drives job growth. That's because decisions on extending the PTC usually occur at the last minute after getting caught up in budget bills.
It also means most of the solar jobs created won't be reflected in data released from the Bureau of Labor and Statistics, which only tracks power generation jobs. The need for cleaner, cheaper, and more distributed energy, on the other hand, may be something to consider. We Fools may not all hold the same opinions, but we all believe that considering a diverse range of insights makes us better investors. The Middlebury plant uses about 20,000 tons of fuel a year, compared to the 650,000 tons per year that a 50 MW facility requires. RECs thus essentially serve as a demonstration that a certain amount of power has been generated from renewable sources. For instance, while the data above show that less than 2,000 solar jobs existed in power generation at the halfway mark in 2014, The Solar Foundation maintains that over 173,000 Americans worked in solar-related positions at the end of last year.
The value of RECs fluctuates significantly, but at current prices, a 50 MW biomass plant may generate from $5 million to $10 million a year.
