Prospects For Energy Saving And Emission Reduction By Using Biodiesel On Marine Fishing Vessels

In the21stcentury, world energy consumption is strong, the contradiction betweensupply and demand is increasingly significant, traditional fossil fuels are still the subjectof world energy consumption. As a representative energy, oil prices remained high, andposed serious challenges on the national economic development and people’s lives.High consumption of fossil fuels inevitably lead to atmospheric pollution, globalwarming and frequent extreme weather caused by greenhouse gases emissions hasattracted widespread attention from the international community. At persent, the worldhas entered a low-carbon era of “low energy, low pollution, low emission”, the taskbreaks no delay to reduce emissions of greenhouse gases. It had discussed the globalemissions reduction agreement from2012to2020on the World Climate Conference inCopenhagen. As the largest carbon emissions country, China is facing tremendouspressure to reduce emissions. As a non-road movement source, the exhaust emissions offishing vessels have became an important part of air pollution in the global environmentand attracted wide attention from the international community because of the difficultyin control, low limit and long-neglected. Coupled with increasingly depleted and highcost of oil resources, fuel costs accounted for an increasing proportion of the total costin marine fishing industry. Under the pressure of environment and energy, it hasimportant strategic significance to develop alternative energy that can be used on fishingvessels. From2010, China has focused on the energy conservation and vigorouslypromoted the development of new energy used on fishing vessels, such as liquefiednatural gas, hydrogen, biofuels and solar energy, wind energy, tidal energy. But, the usepatterns of solar, wind and tidal energy are mainly converted into electrical energy toassist the electricity demand of fisheries production, and can not be used as alternativeenergy on diesel energy. Although liquefied natural gas can be used as a liquid fuel, it isalso non-renewable resource and the reserces will be dwindling as fossil energy. As aclean, renewable energy which has the similar performance to petroleum diesel that canbe mexed use in a diesel engine, biodiesel can be a better alternative energy in thepost-oil era with significant emission reduction effects. In this study, we analyzed the feasibility of biodiesel for boats engines based on a comparison of biodiesel andordinary marine diesel characteristics, and then made a prosepects analysis on thepromotion of biodiesel using in practice from a qualitative and quantitative analysis. Inthis paper, firstly, exploring the reduction strategies of fishing boats using biodieselbased on evolutionary game theory. Analyzing the dynamic changes of the proportion offishermen,fishermen and enterprises that adopted different strategies with boundedrationality, as well as the conditions for stable strategy. Considering that subsidy policyof the government, supervision of the fishing department and effective implementationof carbon trading can change the fishermen’ benefit matrix to induce fishermen toreduce emissions by using alternative energy sources. Then, estimating the costs andbenefits for the reduction of fishing vessels. The results showed that, biodiesel is withsignificant benefits on emission reduciton, but the current price is slightly higher thanordinary diesel, its application in the marine fishing vessels will lead to a further rise inthe cost of fuel, and engine fueled with B5biodiesel will increase of about$500in fuelcosts per boat annual. If the Government was able to develop subsidy policy onbiodiesel, and establish an effective carbon trading system, under the premise of asignificant cost advantage, the fishermen would gradually adopt biodiesel using onfishing vessels.
