How Does Biomass Energy Outperform The New Energy Era?
Jan 11, 2019

Professor Jia Liming, deputy director of the National Energy Non-grain Biomass Raw Materials R&D Center of Beijing Forestry University, and Su Shuzhen, a professor at the center, believe that China's forestry biomass energy research and development has a different approach. Enterprises and research institutes have cooperated to explore a plantation model of intensive cultivation of raw material forests. The industrial chain model of multi-generation of products and the new path of sustainable development mode of the whole life cycle are worth looking forward to. Because of this, the French Development Agency are optimistic about many biomass energy companies in China.


Brazil, the United States and the European Union started early and developed technology, but they are widely criticized for their food crops. The second generation of biomass energy is on the rise.


With the gradual depletion of fossil energy, increasing air pollution, and increasing global climate change, biomass energy has emerged with its many advantages such as renewable, carbon neutrality and environmental friendliness, attracting worldwide attention and developing biomass energy. Has been included in the energy development strategy of each country.


Biomass energy in Brazil, the European Union and the United States started early, each with its own merits, but the real industrialization is still the first generation of biofuels and solid fuels. The annual production of sugarcane ethanol in Brazil exceeds 25 billion liters, and its application scale exceeds 50% of the national gasoline fuel consumption; the annual production of corn ethanol in the United States has exceeded 40 billion liters. The United States, Brazil, Indonesia and other countries have developed rapidly in biodiesel production. The main raw materials are rapeseed, soybean, palm and other crops as well as waste oil. In 2014, US and Brazilian soybean biodiesel production exceeded 2 million tons. Indonesian palm biodiesel The output exceeds 3.8 million tons.


Many countries in Europe develop particle-forming fuels as biomass energy sources. Sweden mainly produces biomass cogeneration by planting willow energy forests, generating about 100 billion kilowatt-hours of electricity per year, accounting for 16.5% of national energy consumption, accounting for 68.5% of total heat energy consumption; Denmark's biomass direct-fired power generation agriculture and forestry The annual consumption of waste is about 1.5 million tons, accounting for 5% of the country's electricity supply.

Biomass energy in the United States and Austria account for 4% and 10% of primary energy consumption, respectively. Germany uses bio-waste dry fermentation to produce biogas for cogeneration, which accounts for about 7% of the country's electricity.


"Relying on food crops to produce material energy, contrary to the principle of food security, the international community has accused the United Nations of trying to stop the production of corn ethanol in the United States. Therefore, the international community began to explore the second generation of bio-liquid fuels, mainly cellulosic ethanol. In 2006, the United States formulated the 'Cellulose Ethanol Research Roadmap' and in 2008 released the 'National Biofuels Action Plan', which is in the process of further research and development of cellulosic ethanol raw material cultivation and transformation technology." Jia Liming said, "Brazil is also developing conversion technology. Cellulose ethanol is produced from bagasse as raw material. At present, there are many cellulosic ethanol raw materials developed in the world: sweet sorghum, switchgrass, pennisetum, miscanthus and other herbaceous plants, poplar, eucalyptus and other species; transformation technology has pyrolysis Law, enzymatic hydrolysis, chemical methods, physical chemistry, etc. Biodiesel is also developing in the direction of high-end bio-jet fuel."


China's development to adjust food security - not to compete for food, not to compete with food, forestry has become a "high-quality stock" with great potential.
