The recovery of energy and valuable compounds from exhaust gases in the iron and steel industry deserves special attention due to the large power consumption and CO 2 emissions of the sector. In this sense, the hydrogen content of coke oven gas (COG) has positioned it as a promising source toward a hydrogen-based economy which could lead to economic and environmental benefits in the iron and steel industry. COG is presently used for heating purposes in coke batteries or furnaces, while in high production rate periods, surplus COG is burnt in flares and discharged into the atmosphere. Thus, the recovery of the valuable compounds of surplus COG, with a special focus on hydrogen, will increase the efficiency in the iron and steel industry compared to the conventional thermal use of COG. Different routes have been explored for the recovery of hydrogen from COG so far: i) separation/purification processes with pressure swing adsorption or membrane technology, ii) conversion routes that provide additional hydrogen from the chemical transformation of the methane contained in COG, and iii) direct use of COG as fuel for internal combustion engines or gas turbines with the aim of power generation. In this study, the strengths and bottlenecks of the main hydrogen recovery routes from COG are reviewed and discussed.

In recent years, regarding the influence of the production processes and vehicles on the environment, new technical solutions for reducing air pollutions have been studied and developed. One of the new constructions is fuel cell electric vehicle (FCEV). The production and running conditions of the vehicles are specific in different countries. Hence, a study of these conditions and fuel production process is needed. In this paper, a study of the FCEV efficiency, at different producing technologies of hydrogen (H2), is carried out. Life cycle assessment (LCA) method is used. A comparison, concerning fuel consumption and emissions as CO2 equivalent for the whole life cycle, is done for FCEV and conventional gasoline vehicle (GV). The influence of the energy mix and technology of production of hydrogen on spent energy and air pollution is analyzed. As the results show, in countries with CO2 emissions over 447 g per 1 kWh electricity, the technology of hydrogen production from natural gas is most effective. Now and in the near future, the ecological and financial advantages, connected to renovation of existing vehicle fleet with FCEV, are not absolutely verified.

“…The best known methods for obtaining hydrogen include: natural gas reforming, coal or coke gasification, plasma technology, water electrolysis, photoelectrolysis, biological methods. In the reforming process, 8.34 kg of carbon dioxide is produced per 1 kg of hydrogen in the hydrogen production installation alone [9]. The hydrogen oxidation process itself in a hydrogen cell car is a completely zero emission process, i. e. the only emission is pure steam/water.…”

The constant increase in demand for energy and its carriers and the growing normative requirements in terms of eco-friendliness and reduction of CO 2 emissions make it necessary to look for new sources of energy supply. Decreasing resources of conventional energy sources, including oil, the dynamic development of the road transport sector and the consequent increase in the number of vehicles on the roads have a negative impact on the air and environment. This makes it necessary to systematically increase the share of biofuels to minimise the negative environmental impact. It should be stressed that all new solutions must be sustainable and take into account the care of the environment. The manuscript analyses the possibilities of using alternative sources of automotive engine propulsion, with a particular focus on wood gas, petrol, methane and LPG (Liquefied Petroleum Gas). Using the example of a car equipped with the 1.1 Fire engine, a computer simulation has been developed to reproduce the NEDC (New European Driving Cycle) driving cycle. The simulation model used in the analysis was developed in Scilab environment. The computer simulation scheme consisted of five blocks taking into account the contour characteristics maps of the engine under analysis. As the results of the simulation have shown, when the engine is powered by wood gas, there is a significant drop in power. This is due to the much lowerc alorific value of woodgas and the lower air demand for the conversion of the fuel unit. Methaneturned out to be a carrier with parameters more similar to those of conventional fuel. In this case, there has been a smaller decrease in the power achieved by the engine.
