Where Does Biomass Power Go Without State Subsidies?
- Jun 27, 2018 -

We will vigorously develop combined production of biomass, heat and electricity, which does not depend on subsidies

Under the global low carbon, environmental protection and green development boom, with the continuous development of renewable energy industry, more and more countries and regions will be renewable energy heating into the regional energy development strategy and planning as a whole.

"To realize clean heating, is a major strategic task of China's current and future, in this context, cogeneration became an important part of the renewable energy of biomass energy is one of the best development direction.", chairman of the China biomass energy industry union xiao-ping Chen in the recently held "2018 Dan clean renewable energy in heating peak BBS" that biomass clean heating in small and medium-sized area has the congenital superiority of civil and industrial heating, developing biomass cogeneration, can effectively reduce dependence on fossil energy, coal, and make contributions to win the battle blue sky.

Explore an operating model that does not rely on subsidies

The deputy secretary-general of China biomass energy industry union being too country-specific said in an interview, in recent years, the annual output of biomass power generation in China is about 80 billion degrees, 1.4% of annual total output in China, although the proportion is limited, but from the Angle of environmental protection, people's livelihood, biomass energy industry is indispensable.

It is understood that the building of a 25 mw biomass power plant (power plant), more than 30, ten thousand tons of annual consumption, agriculture, forestry and the rest of the waste, according to 300 yuan/ton price calculation, can form the city $90 million a year in the purchase and sale of biomass, the livelihood of the people, environmental protection is of great significance.

There is no doubt that China's biomass energy market has great potential for development.In the first quarter of 2018, China added an additional installed capacity of 900,000 kilowatts of biomass power generation, with a cumulative installed capacity of 15.75 million kilowatts, an increase of 24% over the previous year.Biomass power generation reached 17.86 billion KWH in the first quarter, up 19.1% year on year, and maintained a steady growth momentum.However, in zhang's view, despite the promising development momentum of the industry, it is important to recognize that China's biomass energy industry mainly relies on power generation and government subsidies for its unsustainable development model."At present, about 50 percent of the income of China's biomass energy enterprises comes from the national renewable energy subsidy."Biomass power generation back fill, he thought, is a trend, business single, inefficient, low added value and rely on the development of the national policy dividend model has not applicable, biomass energy rely on subsidies enterprise development prospect is not optimistic.

The development of biomass energy industry in China as a whole is at the initial stage, and the profit model is still being explored.With the continuous improvement of environmental protection standards and the increasing cost of raw materials and labor, the development cost of biomass energy in China has been increasing year by year, and the profitability of the project has been decreasing gradually.China's emission standards for biomass power generation and heating are not clear, and there are difficulties in project approval in some areas, which bring great challenges to the development of biomass energy industry.

"Biomass energy industry in our country to develop in the direction of high efficiency, high value-added, low energy consumption, industry to explore innovation as soon as possible to reduce subsidies dependence, even does not depend on subsidies to business operation mode."Being too country-specific said, biomass energy industry in waste gas, waste water discharge, etc., relevant state departments to strengthen supervision, industry, enterprise also to strengthen self-discipline, and keep the information transparency, the benign interaction, and the surrounding residents and promote the benign development of the industry.

Upgrade to comprehensive energy services

Participating experts said, the future, biomass energy industry in China should be made by a single biomass power generation from biomass cogeneration or biomass heating (cold) development direction transformation, on this basis, to upgrade the development towards a comprehensive energy service, explore provide electricity, heat and related value-added services, etc., for example, to provide users with facilities optimization solution.

In terms of heating, at present, our country clearly support the development of biomass energy heating, according to the relevant guidance, by 2020, biomass cogeneration installed capacity of more than 12 million kw, total biomass heating or heating area of 1 billion square meters, the annual directly instead of about 30 million tons of coal.

"To this end, we should vigorously develop biomass combined heat and electricity production."Zhang dayong said that in the future, biomass energy should be more heat supply and less power generation, and should be developed to the operation mode of heating and power generation.From their own characteristics, as well as overseas practice of application of biomass energy in small and medium-sized area has the congenital superiority of civil and industrial heating, cogeneration, achieve clean heating, is the development of biomass energy industry, the optimal direction.In this regard, Denmark, one of the most energy efficient countries in the world, has experience to learn from.

Currently, 63 percent of households in Denmark have regional heating, and about 60 percent of their electricity comes from combined heat and power generation, which is 92 percent efficient.The overall energy efficiency of combined heat and power generation is much higher than that of separate heating and power generation, which can be as high as 85-90%, and can save 30% of fuel compared with individual heating and power generation."Regional heating and cogeneration has become and will continue to be a key factor in Denmark's green transformation."That includes a large number of biomass energy projects, yu yuming, President of danfoss's heating division in China, Asia Pacific and India, and chairman of the Danish regional heating commission's China division, told reporters.He also said that Denmark has now achieved on-demand heating, per square meter charge.

Zhang dayong said that in China, biomass energy will play a bigger role in clean heating, air pollution prevention and targeted poverty alleviation.The biomass energy industry should strengthen communication and coordination with the departments of energy, finance, price and ecological environment, so as to accelerate the development of biomass combined heat and power production and biomass heating (cooling).
