Its low bulk density and uneven particle size create logistical and technical issues in transportation, storage, and utilization 49. Additionally, the high moisture content of biomass makes it susceptible to mould growth and other forms of biodegradation 206. Second-generation bioethanol production utilises lignocellulosic biomass, a more sustainable and abundant alternative to food-based raw materials. These feedstocks, rich in cellulose, hemicellulose, and lignin, are non-food materials, thus avoiding direct competition with food supply chains and contributing to waste reduction and resource efficiency.

2 Sustainability challenges

Well formulated FITs in some developed nations have been found to be effective in stimulating the development of renewable energy technologies, ultimately increasing electricity consumption 192, 193. For tariff policies to be effective, they should be consistent and be supported by other policy instruments 190. Modern, solid biomass use expands the most, accounting for nearly 80% of new bioenergy use. Bagasse used in India’s expanding sugar industry for heat and electricity supports much of this growth.

Solar & battery products

Solar output has doubled since 2022, rising from 96 TWh to 196 TWh in 2025, reinforcing India’s position as the world’s third-largest solar generator, with nearly double the generation of fourth-placed Japan (101 TWh). To fuel all of the world’s aviation demand, global biofuels would need to more than triple and be exclusively used for air travel. Sugarcane — mostly produced in Brazil — is the second largest source, followed by oil crops including palm oil, soy oil, and rapeseed. Bioenergy accounts for a relatively small share of the world’s electricity, but, as we’ll see, in some countries, it’s a substantial source of power.

• When handling biomass, proper safety protocols must be followed to prevent accidents or exposure to harmful substances.
• These programs are an excellent way to gain the skills and knowledge needed to jumpstart your career.
• When upgraded they can also be injected into existing natural gas pipelines or used by natural gas vehicles.
• With its wide array of feedstocks, technological pathways, and end-products, the biomass-to-energy conversion process also underscores bioenergy’s versatility and its potential to transform the global energy system.

Bioenergy Power Generation

From start-up inception in 2012 to the verge of plant operation in 2023, ARENA has supported biomass-to-energy company Renergi along its renewable energy journey. We share knowledge, insights and data from our projects to help the renewable energy industry and other projects learn from each other’s experiences. An educational and entertaining Bioenergy Coloring and Activity Book is available that offers a learning experience to teach key bioenergy facts and raise awareness of renewable energy. In India, FAO is is supporting the country to harness crop residue for https://www.thisisdornoch.com/listing/lower-whinhill/ the production of alternative fuels such as compressed biogas (CBG) and biomass… “The prompt agreement between the Irish Government and the European Commission on the detail of the renewable heat obligation is critical to ensure the legislative process can be completed to protect and grow Ireland’s biomethane sector.

• It is reported that using biomass as fuel for power generation reduces the CO2 emission about to 95% 23.
• The advantage of AFEX is as it preserves most of the hemicellulose and minimizes the formation of fermentation inhibitors.
• However, its applicability can be limited by the high cost and recovery requirements of ammonia 109.
• Bioenergy is a promising alternative to fossil fuels-based energy with significant potential to transform global energy systems and promote environmental sustainability.
• Metabolic engineering can optimize these processes, resulting in higher yields of biofuel precursors and improving the overall economic viability of bioenergy crops.

Figure 3 demonstrates the production of bioethanol using Lactobacillus casei to ferment sugarcane bagasse, a byproduct of sugar production. Bioethanol’s versatility, coupled with advancements in production methods and the utilization of diverse feedstocks, positions it as a key contributor to a sustainable energy future. In the first generation of bioethanol production, Saccharomyces cerevisiae ferments carbohydrate and starch-based raw materials via direct fermentation or hydrolysis/fermentation processes.

These four centers are working to lay the scientific groundwork for a new bio-based economy. Their goal is to coordinate with applied researchers to help develop a range of new products and fuels derived directly from renewable, nonfood biomass. Physicochemical conversion of biomass achieved by alter the physical and chemical structure of lignocellulosic materials to improve their conversion into biofuels and valuable chemicals. However, these processes can produce inhibitory byproducts like lignin-derived phenolics, carboxylic acids, and furan derivatives, which may inhibit enzymatic activity and fermentation efficiency 108.

To maintain renewable energy’s rapid growth, new IEA study assesses challenges and shows how to overcome obstacles.

Microalgae’s high lipid content of about 70% makes them a valuable source for biodiesel production. A small amount of algal biomass can yield a substantial volume of biodiesel, with oil content up to 100 times greater than that of terrestrial crops like soybeans. Furthermore, microalgae can produce between 5,000 and 20,000 gallons of oil per acre annually, which is 7–30 times more than traditional oilseed crops 137,138,139. Given its high lipid content, efficient growth conditions, and environmental benefits, algal biomass is a promising primary feedstock for biodiesel synthesis.

Pyrolysis is the process of heating biomass in the lack of air to create bio-oil, gas, and char. Hydrothermal liquefaction is the process of burning material in water under high pressure to create a liquid fuel. Beyond converting biomass to biofuels for vehicle use, it can also be used in the manufacturing of bioproducts such as plastics, lubricants, industrial chemicals, and many other products.
