Faced with increasingly serious climate and environmental problems, the green transformation of the energy structure is imminent. Energy development is related to a country’s economic lifeline, and the level of energy green transition is a key factor in determining the degree of low-carbon economic development. As an important way to internalize the externalities of environmental behavior, the degree of perfection of economic policies has a direct impact on the energy transition process. As an important means to promote the adjustment of energy structure, economic policies can internalize the positive or negative externalities of corporate environmental behaviors, and play an unparalleled role in the process of promoting the green transformation of energy. This article takes Germany, France, Japan, and Australia as the research objects of the four countries with relatively advanced energy transition economic policy systems, and fully analyzes the above-mentioned countries’ practices in fiscal and taxation policies, green finance, and market systems, and combines China’s energy transition economic policies. Implementation status, and corresponding suggestions for the construction of China’s energy transition policy system.

The coordination development of economy-energy-environment was discussed with traditional environmental loads model, combined with "decoupling" theory. Considering the possibilities of social and economic development, this paper set out three scenarios, and analyzed quantitatively the indexes, which affected carbon dioxide emissions, including population, per capita GDP, industrial structure and energy structure. Based on this, it forecasted carbon dioxide emissions in China in future. By comparing the prediction results, it held that policy scenario was the more realistic scenario, what’s more it can achieve emission reduction targets with the premise of meeting the social and economic development goals. At last, it put forward suggestions to implement successfully policy scenario, from energy structure, industrial structure, low-carbon technology and so on.

Palm oil mill effluent (POME), a pollutant produced by the palm oil industry, was treated by the Vetiver system technology (VST). This technology was applied for the first time to treat POME in order to decrease biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In this study, two different concentrations of POME (low and high) were treated with Vetiver plants for 2 weeks. The results showed that Vetiver was able to reduce the BOD up to 90% in low concentration POME and 60% in high concentration POME, while control sets (without plant) only was able to reduce 15% of BOD. The COD reduction was 94% in low concentration POME and 39% in high concentration POME, while control just shows reduction of 12%. Morphologically, maximum root and shoot lengths were 70 cm, the number of tillers and leaves was 344 and 86, and biomass production was 4.1 kg m−2. These results showed that VST was effective in reducing BOD and COD in POME. The treatment in low concentration was superior to the high concentration. Furthermore, biomass of plant can be considered as a promising raw material for biofuel production while high amount of biomass was generated in low concentration of POME.

Hydrogen is an increasingly important chemical raw material and a probable future primary energy carrier. In many current and anticipated applications the carbon monoxide impurity level must be reduced to low-ppmv levels to avoid poisoning catalysts in downstream processes. Methanation is currently used to remove carbon monoxide in petroleum refining operations while preferential oxidation (PROX) is being developed for carbon monoxide control in fuel cells. Both approaches add an additional step to the multi-step hydrogen production process, and both inevitably result in hydrogen loss. The sorption enhanced process for hydrogen production, in which steam-methane reforming, water-gas shift, and carbon dioxide removal reactions occur simultaneously in the presence of a nickel-based reforming catalyst and a calcium-based carbon dioxide sorbent, is capable of producing high purity hydrogen containing minimal carbon monoxide in a single processing step. The process also has the potential for producing pure CO2 that is suitable for subsequent use or sequestration during the sorbent regeneration step. The current research on sorption-enhanced production of low-carbon monoxide hydrogen is an extension of previous research in this laboratory that proved the feasibility of producing 95+% hydrogen (dry basis), but without concern for the carbon monoxide concentration. This paper describes sorption-enhanced reaction conditions – temperature, feed gas composition, and volumetric feed rate – required to produce 95+% hydrogen containing low carbon monoxide concentrations suitable for direct use in, for example, a proton exchange membrane fuel cell.

In this article analyzes the development of trends of bioenergy crops market development in Ukraine and its current state are analysed. The possibility and feasibility of synergy of mutual development of bioenergy crops market and bio-oil market in Ukraine were noted. The necessity of state support and stimulation of bioenergy crops and different types of biofuels production in Ukraine was stated. A positive trend of growth of planted areas and production of rapeseed in Ukraine was revealed. During the study period (2013-2019) the production of rapeseed was increased by 1.4 times. The greatest energy potential for the production of bioethanol is in the sugar beet subcomplex of the agricultural sector. Over the past few years, the production of sugar beet was at its highest in 2014 (15.7 million tonnes), while the following years saw a decrease in cultivated areas of sugar beet and, consequently, a drop in its gross output - to 8.3 million tonnes in 2020. Significant resource potential for the production of bioethanol also have cereal crops (wheat, rye, barley, maize), the area under which during the last ten years remains relatively stable (14.4-15.3 million ha). Among grain crops the most effective raw material for the production of bioethanol is maize. A positive tendency of biennial growth of planted area under this crop is revealed. The space differentiation of resource base of bioenergy in Ukraine is prominent. The cluster analysis revealed three groups of areas based on the similarity of the energy resources for bioenergy purposes. Two clusters including Khmelnytskyi, Ternopil, Zhytomyr and Chernihiv, Vinnytsia, Cherkasy, Sumy, Kirovograd, Poltava and Kyiv regions should be considered as the most promising areas for concentration of capacities in biofuel production. It is noted that the trajectory of development bioenergetic sector of the country is always conditioned by compromise between compliance with optimal levels of its energy and food security.

Micro, Small and Medium Enterprises (UMKM) has an important role in the Indonesian economy, one of which can help the per capita income of the Indonesian state, especially in Banyuwangi Regency, as well as in the UM Banana Sale UD UD. Sumber Alam Buana, located at the eastern end of the island of Java, precisely in Banyuwangi. The UMKM is one of Banyuwangi's original typical food businesses from Ambon banana raw material, bearing in mind that typical food is identical to souvenirs (souvenirs) when visiting Banyuwangi, certainly not forgetting to bring and share them with you. However, there are problems in the field of production of UD Banana Banana UD, namely the low production capacity of processing banana raw materials because it still uses a cutting knife and the appropriate method has not been applied to record raw materials or finished goods so that the owner is less able to control the cycle of raw materials or finished goods. While in the marketing sector it is still conventional to be entrusted in a gift shop so that it can only wait for whether the product is sold or vice versa. The solution to the development activities of UMKM Sale Banana UD Sumber Alam Buana includes counseling and training using a banana chopper tool that is more efficient than a knife that has been used to chop banana raw materials. Whereas in terms of recording to help partners to control raw material inventory and finished goods efficiently and effectively, the need for training knowledge and assistance to owners and employees using a perpetual method stock card (inventory). To expand market share that has demanded the use of technology, training is held to make e-mail as a portal to access several e-commerce websites and to open online stores through social media such as Facebook and others. The results achieved in the Community Service program are the development of this business in terms of increasing production capacity, managing raw materials, expanding markets and increasing income.
