Biomass as a source of renewable energy:
environmental aspects Automatic translate

Biomass is an increasingly important component of the global renewable energy transition strategy, offering environmental benefits and challenges. This organic material, derived from plants, wood and waste, is a sustainable energy resource with the potential to significantly reduce greenhouse gas emissions when managed and used correctly. Biomass participates in the natural carbon cycle, which distinguishes it from fossil fuels and makes it more climate-neutral.

However, the environmental impacts of its use depend on production methods, types of biomass, and energy conversion technologies. While biomass can help reduce pollution and waste, unsustainable practices can lead to deforestation, land degradation, and land-use conflicts. Current technologies and approaches aim to maximize the environmental benefits of biomass, ensuring its role as a viable component in the global energy transition.

The concept of biomass and its varieties

Biomass is organic material derived from plants, trees, agricultural waste, and organic waste. This material can be used as a renewable energy source to replace fossil fuels. Biomass contains stored solar energy absorbed by plants through photosynthesis, which can then be converted into heat or electricity.

Main categories of biomass

Biomass can be classified into several main categories:

Agricultural Residues : This includes rice husks, sugarcane bagasse, wheat straw and other agricultural waste. These materials are generated in large quantities and can be used to produce energy instead of being simply thrown away or burned in the field.

Forest waste : This includes branches, wood chips, sawmill waste, and other byproducts of the forest industry. Using these materials to produce energy makes use of waste that would otherwise cause forest fires or be left to rot.

Organic waste : This includes household organic waste, sewage sludge and food waste. These materials can be converted into biogas or other forms of energy, which helps solve the waste disposal problem.

Energy crops : These are plants grown specifically for energy production, such as miscanthus, corn, or sugarcane. These crops can be grown on land that is not suitable for food production, thereby avoiding competition with food production.

Biomass has significant environmental and economic benefits, including healthy forests, improved air quality, and is a reliable source of renewable energy.

Biomass as a renewable energy source

Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist. Plants absorb solar energy through photosynthesis, and this chemical energy can then be used for a variety of purposes.

The role of biomass in modern energy

Biomass plays an important role in modern energy, especially in the context of the transition to more sustainable and environmentally friendly energy sources. It can be used to produce heat, electricity and biofuels.

Biomass plays a significant role in the energy balance of many countries, especially in regions with large forest resources or developed agriculture. For example, in Scandinavian countries, biomass is one of the main sources of energy for heating and electricity production.

Technologies for obtaining energy from biomass

There are several technologies that can convert the energy contained in biomass into useful forms of energy:

Direct combustion : This is the simplest and most common method, where biomass is burned to produce heat, which can then be used for heating or converted into electricity using steam turbines.

Gasification : This process involves heating biomass at high temperatures in a limited oxygen environment, resulting in the formation of synthetic gas (syngas) that can be used to generate electricity or converted into liquid fuels.

Pyrolysis : This process involves heating biomass in the absence of oxygen, resulting in the formation of biochar, bio-oil and gases that can be used for various purposes.

Anaerobic Digestion : This biological process involves the breakdown of organic material by microorganisms without the presence of oxygen, resulting in the formation of biogas, which can be used to produce heat and electricity.

Biofuel Production : Biomass can be converted into various liquid fuels such as bioethanol and biodiesel which can be used in the transport sector.

Each of these technologies has its own advantages and disadvantages, and the choice of a particular technology depends on many factors, including the type of biomass, available resources, and specific needs.

Environmental benefits of using biomass

Using biomass as an energy source offers a number of environmental advantages over fossil fuels:

Reduced Greenhouse Gas Emissions : When managed properly, biomass use can significantly reduce net greenhouse gas emissions because the carbon dioxide released from burning biomass is absorbed by growing plants, thus creating a closed carbon cycle.

Waste Recycling : Using biomass allows for the recycling of waste from wood processing, agriculture and food processing that would otherwise be dumped in landfills, openly burned or cause forest fires.

Preventing Fires and Uncontrolled Burning of Waste : Using forest waste for energy production can help reduce the risk of forest fires, which are a serious environmental problem in many regions.

Use of ash as mineral fertilizers : Ash generated during biomass combustion can be used as mineral fertilizer, which promotes the circulation of nutrients in nature.

Reducing dependence on fossil fuels : Increasing the use of biomass can help reduce dependence on fossil fuels, resulting in reduced emissions of greenhouse gases and other pollutants associated with fossil fuel extraction and use.

Improved air quality : Modern biomass combustion technologies produce significantly lower emissions of harmful substances compared to fossil fuels, resulting in improved air quality.

Promoting sustainable forest and land management : Biomass use can promote sustainable forest and land management practices that contribute to the conservation of biodiversity and ecosystem services.

Environmental issues of biomass use

Despite its many benefits, the use of biomass also comes with certain environmental concerns and risks:

Deforestation and land degradation : Unsustainable biomass harvesting can lead to deforestation and land degradation, which in turn can lead to soil erosion, desertification and loss of biodiversity.

Air Pollution : Burning biomass releases harmful gases and particulate matter into the atmosphere, which can lead to air pollution and health problems, especially when using older technologies or when burning wet biomass.

Competition for land and water : Growing energy crops can compete with food production and other land uses, and can require significant amounts of water, which can lead to water stress in some regions.

Loss of biodiversity : Monoculture cultivation of energy crops can lead to loss of biodiversity and disruption of ecosystem functions.

Production and transportation emissions : The production and transportation of biomass can require significant energy inputs and result in greenhouse gas emissions, which can reduce the overall environmental benefits of biomass use.

Land use change : Conversion of natural ecosystems to energy crop plantations can result in greenhouse gas emissions and loss of ecosystem services.

Economic inefficiency : In some cases, biomass energy may be less economically efficient and require significant investment in infrastructure and maintenance.

These challenges highlight the need for sustainable management and use of biomass, as well as the development of more efficient and cleaner technologies for its conversion into energy.

Carbon cycle of biomass

The carbon cycle of biomass is one of the key aspects determining its ecological role and potential for climate change mitigation.

Carbon Cycle Process

Biomass participates in the natural carbon cycle as follows:

1. Plants absorb carbon dioxide (CO2) from the atmosphere through photosynthesis and use the carbon to form their structure and grow.
2. When plants die, they decompose and much of the stored carbon is released back into the atmosphere as CO2.
3. When biomass is used to generate energy, this process is accelerated: the carbon stored in the biomass is released as CO2 when burned.
4. New plants growing in place of the harvested ones again absorb CO2 from the atmosphere, thus closing the cycle.

This closed cycle distinguishes biomass from fossil fuels, which release carbon stored for millions of years in geological reservoirs, adding a net increase in CO2 to the atmosphere.

Carbon neutrality of biomass

The concept of carbon neutrality of biomass is based on the assumption that the amount of CO2 emitted when biomass is burned is equal to the amount of CO2 absorbed by plants as they grow, making the overall CO2 balance neutral.

However, in practice, carbon neutrality of biomass can only be achieved if certain conditions are met:

1. Biomass must be obtained from sustainably managed sources where the collection rate does not exceed the regeneration rate.
2. The energy used to collect, transport and process biomass should be minimised and, ideally, also derived from renewable sources.
3. Emissions of other greenhouse gases during the production and use of biomass should be minimised.

If these conditions are not met, the use of biomass may actually result in a net increase in greenhouse gas emissions, especially in the short term.

The time factor in the carbon cycle

An important aspect of the biomass carbon cycle is the time factor. Although burning biomass releases CO2 instantly, the uptake of this CO2 by growing plants occurs gradually over their life cycle.

This means that in the short term, biomass use can lead to a net increase in atmospheric CO2 concentrations, especially when using woody biomass, as trees take many years to grow and fully absorb the released CO2.

This time gap between CO2 emissions and uptake becomes particularly important in the context of urgent action to mitigate climate change.

Comparison of biomass with fossil fuels

Comparison of biomass with fossil fuels is an important aspect in assessing its environmental impact and potential to replace traditional energy sources.

Environmental aspects of comparison

From an environmental point of view, biomass has several advantages over fossil fuels:

Renewability : Biomass is a renewable resource, whereas fossil fuels are exhaustible and will not be renewed in the foreseeable future.

Carbon Cycle : When managed sustainably, biomass participates in a closed carbon cycle, whereas fossil fuels add new carbon to the atmosphere that was buried millions of years ago.

Emissions of sulfur and other pollutants : Burning biomass produces significantly lower emissions of sulfur and some other pollutants than coal and some other fossil fuels.

Local production : Biomass can be produced locally, reducing the need to transport fuel over long distances and associated greenhouse gas emissions.

However, biomass also has some disadvantages compared to fossil fuels:

Energy density : Biomass has a lower energy density compared to fossil fuels, meaning that more biomass is required to produce the same amount of energy.

Particulate and Certain Gas Emissions : Biomass combustion, especially when using older technologies, can produce significant emissions of particulate matter and certain gases that may be harmful to human health.

Land use : Biomass production requires significant land resources, especially for growing energy crops, which may compete with other land uses such as food production or conservation of natural ecosystems.

Water Resources : Growing some energy crops can require significant amounts of water, which can be problematic in areas with limited water resources.

Energy efficiency

In terms of energy efficiency, fossil fuels often have an advantage over biomass:

Energy Conversion Efficiency : Modern fossil fuel power plants, especially natural gas, can achieve high efficiency values, while biomass power plants typically have lower efficiency.

Stability of Energy Supply : Fossil fuels provide a more stable energy supply, whereas biomass availability can be affected by seasonal factors, weather conditions, and other variables.

Infrastructure : The existing energy infrastructure in most countries is focused on fossil fuels, and switching to biomass may require significant investment in new infrastructure.

Despite these differences, it is important to note that the choice between biomass and fossil fuels is not binary. In reality, a sustainable energy system of the future will likely include a combination of different energy sources, including biomass, as well as solar, wind, hydropower and other renewable sources, with the role of fossil fuels gradually declining.

Modern technologies of biomass use

Modern technologies allow for the efficient and environmentally responsible conversion of biomass into various forms of energy. These technologies are constantly being improved, aiming to increase efficiency and reduce the negative impact on the environment.

Anaerobic digestion is a biological process in which microorganisms break down organic material without oxygen, producing methane-rich biogas:

Single-stage systems : In these systems, all stages of anaerobic digestion occur in a single reactor, making them simple to design and operate.

Multi-stage systems : In these systems, the various stages of anaerobic digestion take place in separate reactors, allowing conditions to be optimized for each stage and increasing overall process efficiency.

Dry Digestion Systems : These systems operate with biomass with high solids content (15-40%), making them particularly suitable for processing certain types of agricultural waste and municipal solid waste.

Wet Digestion Systems : These systems operate with biomass that has low solids content (less than 15%), making them suitable for treating liquid wastes such as slurry and sewage.

Biofuel production technologies

Biomass can be converted into various types of liquid and gaseous fuels that can replace traditional fossil fuels:

Bioethanol production : Bioethanol is produced by fermenting sugars contained in biomass and can be used as an additive to gasoline or as a fuel on its own.

Biodiesel production : Biodiesel is produced by transesterification of vegetable oils or animal fats and can be used as a replacement or additive to diesel fuel.

Biomethane production : Biomethane obtained by cleaning biogas from anaerobic digestion can be used as a replacement for natural gas.

Synthetic Fuel Production : Synthetic fuels can be produced from syngas obtained from biomass gasification, through the Fischer-Tropsch process or other processes.

Bio-oil production from algae : Certain types of microalgae can produce large quantities of lipids that can be converted into biodiesel or other biofuels.

These advanced technologies enable more efficient and environmentally responsible use of biomass for energy production, helping to reduce greenhouse gas emissions and dependence on fossil fuels.
