What is biomass?
Biomass is organic material that can be used in energy production. When biomass is not immediately burned, but converted into liquid or gas-form, it can also be used as a cleaner alternative to more traditional sources of energy for heating or electricity generation.
This article explains what biomass is, how it’s used for energy production, and what benefits and challenges come with it. We also look at how PowerUP supports systems that rely on biomass-based fuels, especially in decentralized energy setups.
Why biomass matters for sustainable energy production
With global demand for renewable energy continuing to rise, biomass offers a unique opportunity. It’s not only a source of power, heat, or fuel — it’s also a way to reduce waste and support local energy independence. In many cases, biomass uses materials that would otherwise be discarded or underutilized. That makes it a practical part of the broader shift toward more resilient and resource-efficient energy systems.
What is biomass? Components and production
Biomass refers to organic material that comes from living or recently living organisms. In the context of energy, biomass usually includes plant-based material and animal waste that can be converted into usable forms of energy such as heat, electricity, or fuel.
Unlike fossil fuels, which take millions of years to form, biomass is renewable on a human timescale. Plants absorb carbon dioxide from the atmosphere as they grow, and when biomass is used for energy, that CO₂ is released again which creates a closed carbon loop.
That’s why biomass is often described as carbon-neutral, though the reality depends on how the material is sourced, transported, and processed.

Different types of biomass explained
There are many types of biomass, each with different characteristics, energy content, and uses. Common categories include:
- Agricultural residues: These include crop leftovers like straw, husks, and corn stover, as well as manure from livestock farming. They are often used in biogas production or burned directly for heat.
- Forestry byproducts: Wood chips, sawdust, bark, and other residues from logging and wood processing can be used as solid fuels.
- Energy crops: Some plants are grown specifically for use as biomass. These include fast-growing species like miscanthus, switchgrass, or short-rotation willow.
- Organic waste: Food waste, industrial byproducts from food and beverage processing, and organic fractions of municipal solid waste are increasingly used as biomass feedstock.
- Sewage sludge and algae: Though less common, these sources are being explored as next-generation biomass due to their abundance and high energy potential.
Each type of biomass has its own energy density, moisture content, and handling requirements, which influence how it’s used in energy systems.
Biomass and energy production — From waste to fuel
Biomass can be converted into energy in several ways, depending on the material and the desired output.
Here are some of the most common uses of biomass in energy production:
- Combustion: Solid biomass like wood chips or pellets can be burned in boilers or furnaces to generate heat or steam, which can be used to produce electricity.
- Anaerobic digestion: Organic biomass such as manure or food waste can be broken down by bacteria in oxygen-free digesters to produce biogas which is a renewable gas primarily made of methane and carbon dioxide.
- Gasification and pyrolysis: These thermal processes convert biomass into syngas (a mix of carbon monoxide, hydrogen, and methane) or bio-oil. These fuels can be used directly or refined further.
- Biofuels: Liquid fuels like biodiesel and bioethanol can be made from oil crops, sugarcane, corn, or even algae. They’re mainly used in transportation.
Biomass is also used in combined heat and power (CHP) systems, where energy is produced near the point of consumption, increasing overall efficiency and reliability.
Benefits of using biomass
Biomass offers a number of practical advantages. First, it’s a renewable resource when sourced responsibly. Many types of biomass are byproducts of other industries, which means they can be used without competing with food production or requiring additional land.
Using biomass also reduces methane emissions from decomposing waste and diverts material from landfills, contributing to more efficient waste management. In rural areas, it can support local energy production, reduce transport distances, and improve energy resilience.
When managed well, biomass helps close material cycles — creating a more circular approach to energy and agriculture.
Challenges and limitations of using biomass for energy production
Despite its benefits, biomass also has limitations. Feedstock availability and transportation logistics can affect both cost and carbon footprint. Some biomass types are bulky or seasonal, requiring storage and consistent supply chains.
There are also sustainability concerns. If land is cleared to grow energy crops or forests are harvested unsustainably, the environmental benefits of biomass can be undermined.
Combustion of biomass can affect air quality if not properly controlled, and energy efficiency may be lower compared to some other renewable technologies. In some cases, biomass systems also require significant maintenance and fine-tuning to handle feedstock variability which may increase production costs.
Biomass in the energy mix
Biomass is one of the few renewable sources that can produce on-demand, dispatchable energy, making it a valuable complement to intermittent renewables like wind and solar. It’s especially relevant for CHP systems, agricultural facilities, and industrial operations with steady waste streams.
Its flexibility also makes it suitable for decentralized energy systems, where local power generation improves grid stability and reduces reliance on large-scale infrastructure.
As part of a broader energy transition, biomass has the potential to support cleaner, more efficient systems. Especially, when combined with smart technology, waste management, and sustainable sourcing practices.
How PowerUP supports biomass-based energy systems
PowerUP works with operators who use biogas and other biomass-derived fuels in CHP units and off-grid energy systems. These setups often face challenges such as gas quality fluctuations, variable feedstock, and non-standard combustion conditions.
We help address these four challenges by:
- Supporting combustion efficiency and engine performance through precise tuning and adaptable components
- Offering condition-based maintenance that minimizes downtime and extends system life
- Providing remote monitoring and diagnostics to detect performance changes early and prevent costly failures
- Supplying high-quality parts designed to withstand the stresses of biogas and biomass applications
Whether your system uses biogas from agricultural waste or heat from solid biomass combustion, PowerUP helps maintain performance, improve reliability, and support a more efficient use of renewable energy resources.
