Environmental aspects of using alternative fuels and biofuels Vladimír Vlk Adviser for sustainable energy and transport 13 th – 14 th October 2011 Prague, Czech Republic
Consumption of the energy sources in the Czech Republic
Potentials for the Czech Republic The potential for the use of renewable energy sources within Czech Republic amounts to 217 PJ/year to 2020, which corresponds more than 45 % of the present-day primary energy consumption. The renewable energy potential is assessed considering restrictions on the areas which could be used for collectors and solar cells, for wind power sites, or for energy crop cultivation. According to statistics, electricity from hydropower, wind, and solar power plants is defined as primary energy. The biggest potential has biomass (77,8 % from global energy) which is as much as usable in all regions of the Czech Republic.
Biofuels for Transport in the latest documents of the Government Government Resolution 1080/2006, - use of biofuels without any support and subsidies. Government Resolution 173/2007, Ministry of Industry and Trade shall prepare multiannual program for subsequent use of biofuels in transport. Government Resolution 531/2007, Ministry of Agriculture shall prepare draft programme for support of high grade blends and pure biofuels according to art. 16, par., 5 of the Directive 2003/96/ES.
Reasons for using of biofuels Reduction of dependence on fossil fuels resources (improvement of energy supply security); Stabilization of greenhouse gas emissions; New opportunities for agricultural sector;
Support of biofuels Promotion of high percentage blends (over 10%) or pure biofuels based on Multi-annual program of subsequent use of biofuels for transport; After European Commission approval the biofuels component will be subject of exemption of excise duty;
Biodiesel production in the Czech Republic Biodiesel production from 1992 until 2008 [thousand tons] Source: Ministry of Industry and Trade
Sustainability Criteria for Biofuels 1 Well to Wheels Analysis of Biofuels vs. Conventional Fossil Fuels Source: Well-to-Wheels analysis of future automotive fuels and power trains in the European context
Sustainability Criteria for Biofuels 2 Verification that forests are not being cut down for palm oil plantations Source: Directive 2009/30/EC
Alternative fuels and propulsion Gaseous fuels (compressed natural gas /CNG/, liquefied petroleum gas /LPG/ and biogas); Biofuels (first generation biofuels e.g. bioethanol from wheat and sugar beet, biodiesel from rapeseed and second generation biofuels a.g. bioethanol from wood and straw and Fischer Tropsch diesel); Hydrogen technology;
Program of public administration vehicle fleet replacement for environmentally friendly vehicles
Why was the Program set up? Decrease in production of greenhouse gas emissions; Improve air quality; Increase in demand for environmentally friendly vehicles; Decrease in environmentally friendly vehicles price;
Aims of the Program Achievement of at least 25 % share of environmentally friendly vehicles in total amount of vehicles in public government by ; Demonstration of environmentally friendly behaviour; Program is focused on passenger cars and light commercial vehicles;
Definition of environmentally friendly vehicles (1) Environmentally friendly vehicle must fulfill emission standard EURO 5, eventually higher, and at the same time the following CO2 emission limits : vehicles category I., i.e. engine power up to 60 kW ◦ emission limit CO 2 up to 135 g/km (positive ignition engine); ◦ emission limit CO 2 up to 120 g/km (compress ignition engine); vehicles category II., i.e. engine power from 61 kW to 80 kW ◦ emission limit CO 2 up to 155 g/km (positive ignition engine); ◦ emission limit CO 2 up to 130 g/km (compress ignition engine);
Definition of environmentally friendly vehicles (2) vehicles category III., i.e. engine power from 81 kW to 120 kW ◦ emission limit CO 2 up to 170 g/km (positive ignition engine); ◦ emission limit CO 2 up to 145 g/km (compress ignition engine); vehicles category IV., i.e. engine power over 121 kW ◦ emission limit CO 2 up to 200 g/km (positive ignition engine); ◦ emission limit CO 2 up to 170 g/km (compress ignition engine); Natural gas vehicles and flexi fuel vehicles do not have to fulfill these emission limits CO 2.
