Opis:
As fuel for fuel cells can be used various substances, but mainly fuel cells are powered by clear hydrogen (or hydrogen obtained from organic substances by reforming process). However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. Due to development of the renewable energy sources, the powering of fuel cells with bio-fuels is very important. Vegetable oil is an alternative fuel for diesel engines and for heating oil burners. Powering high efficiency power sources like fuel cells with renewable fuels (like canola oil) will allow development of renewable energy sources and elimination or reduce of toxic substances emissions. The paper presents the possibility of using canola oil as fuel for direct electricity production. The work shows possible electrooxidation of canola oil emulsion on a smooth platinum electrode in an solution of H2SO4. The resulting current density of canola oil electrooxidation reached the maximum level of 8 mA/cm2. So, the possibility of using canola oil as fuel for direct electricity production has been proved.

Opis:
Prevention of global warming is becoming urgent issue and "biofuel" gathering worldwide attention has been put into practical use not only in US, EU, Brazil or other countries but in Japan. As for its impact on environment, however, evaluation still varies including aninfluence on global economy, for example food price crisis that might have been caused by competition with food. In the previous study [1], one of the authors pointed out that "bio-ethanol" from crops is never "carbon neutra", that means the production and use of the fuel does not lead to a net increase in atmospheric CO concentration, nor useful as a countermeasure against global warming. The "second-generatio" of bio-fuel made from nonfood biomass has attracted much attention especially after the Hokkaido Toyako G8 summit held in November 2008. Among various plants or biomass materials, "Jatropha" has come to the front as one of the most promising candidates for future bio-diesel production. In fact, there are many plans or projects aiming at large scale cultivating Jatropha for bio-diesel oil production in several African or Southeast-Asian countries. However, it should be pointed out that there are too many unknown factors still remaining that are important in practical use of Jatropha oil, for example, productivity as well as sustainability, long-term impact of its large-scale use on soil quality, practical costs of the oil and so on. In this study, an assessment on the validity of Jatropha production was tried as quantitatively as possible using the data obtained from a field survey in Indonesia conducted by the authors in January and March of 2009. Although LCI data for LCA calculations obtained was very limited, the true reality of the situation about Jatropha could substantially be demonstrated to some extent. The main point was that the oil cost was dominated mainly by labor costs, because many work operations could not be mechanized and inevitably be manual handling tasks. In many cases, the labor costs could not be covered by the income from the Jatropha oil (or seed) due to the low productivity of the biomass, whereas the prime cost of the biodiesel oil was rather high expensive compared with fossil fuel.

Opis:
W pracy przedstawiono laboratoryjny sposób produkcji bioestrów, które mogą być wykorzystywane do napędzania wysokoprężnych silników opartych na konstrukcji Rudolfa Diesla. Obecnie najpowszechniej stosowanym biopaliwem są estry metylowe kwasów tłuszczowych EMKT pochodzące z procesu transestryfikacji olejów spożywczych. W przeprowadzonych eksperymentach wykorzystano cztery substraty olejowe - olej rzepakowy, olej słonecznikowy, fryturę przemysłową oraz podczyszczoną fryturę stanowiącą odpad z przemysłu gastronomicznego. W ramach doświadczenia dokonano analizy wpływu rodzaju zastosowanego katalizatora oraz parametrów procesu, takich jak: temperatura środowiska reakcji oraz prędkość i czas mieszania reagentów na wydajność transestryfikacji oraz jakość produktów. Scharakteryzowano wytworzone paliwa, określając ich gęstość, lepkość oraz temperaturę zapłonu. W pracy omówiono także kryteria, jakie powinny zostać spełnione, aby wytworzone biopaliwa mogły zostać wykorzystane do napędzania silników samochodowych, a także przedstawiono podstawowe działania polityczne regulujące krajowy oraz europejski rynek biopaliw.
The necessity of changing conventional petroleum fuels to another kind, which will has lower impact on the environment, had been noticed at the end of XIX century, when the constructor of compression-ignition engine - Rudolf Diesel - demonstrated to the world first engine powered by peanut oil. From that moment, the bio-fuels market has been developed extremely and became to be one of the most popular topics on the international political area. Nowadays, bio-esters are the most popular of alternative fuels, which can be made from natural comestible substrates. This article presents the laboratory way of bio-esters production from four oil substrates - rapeseed oil, sunflower oil, frying fat and waste oil from gastronomic industry. The aim of this experiment was to make an estimation of how some process parameters, such as a kind of catalyst, temperature of the reaction, time and speed of mixing reagents - could influence an efficiency of transesterification process and products quality. Estimation was made of fuels quality based on density, viscosity and the temperature of the flesh-point. Results of the experience gave the opportunity to choose the most economical and ecological method of laboratory bio-diesel production. Moreover this article includes a criteria which needed to be fulfilled to use the bio-fuels in cars engine. It also shows political aspects which regularize European bio-fuels area.

Opis:
This paper describes the results of the preliminary experimental research of the HCCI combustion system in a single cylinder research engine fuelled by means of natural gas containing 95% methane. In this research, influence of the initial temperature of the charge and mixture composition on the maximum combustion pressure, maximum speed of pressure growth, selfignition delay time, combustion time, maximum combustion temperature, heat release and combustion efficiency have been studied. The paper contains: description of the engine modification to adopt it for HCCI operation requirements, applied measurements equipment, selected results of the experimental research. The results shows that initial charge temperature and mixture composition (relative air/fuel ratio coefficient) have essential influence on the engine operating results. The experimental research has been conducted for the varied initial charge temperature from 140 centigrade up to 210 centigrade and for varied relative air/fuel ratio coefficient 1=1; 1=1.5; 1=1.7; 1=2. Maximum charge pressure, maximum speed of pressure growth selfignition delay time was rather unaffected on the initial charge temperature increase beyond 200 centigrade. Previous and current author's research works have indicated that extremely low emissions and high combustion efficiencies are possible to reach if homogeneous charge compression ignition is applied.

Since the beginning of the century, various studies, reports and popular scientific papers have investigated the potential for use of biofuels in aviation. In its recent actions EU also perceives the need for he introduction of sustainable biofuels to help reduce dependence on fossil fuels in air transport and reduce GHG emissions by the air industry. Thus, various feedstocks and conversion technologies for production of biofuels for aviation are currently being investigated within EU (SWAFEA, ALFA-BIRD and Clean Sky JTI). The current EU policy states that sustainable bio-jet fuels are the only option that can be delivered over the medium term, in time to make a significant contribution to EU 2050 emission reduction targets [11]. However, it seems that commercial producers of fuels cannot justify investment in a Bio-Jet fuel production facility until guaranteed availability of sustainable feedstock and clear legislation. EU government is currently taking necessary steps to open a long-term option for the aviation biofuel production in the local market and to support its development. Whereas microalgae is certainly a feedstock considered by many future Bio-Jet producers. Only microalgae seems to offer vast potential as a source of aviation biofuels, however on the more distant horizons of an industry, in which long-term time scales are certainty.

Opis:
Transport is an energy-intensive sector of the economy and it is important where energy comes from and how it is used - now and in the future. The presented research results seem to encourage further work, despite the fact that the work had the character of basic research. The results were achieved in idealized conditions by the fact that the internal combustion engine was tested in static conditions on the test bench and the fuels contained components with strictly defined parameters. These conditions are different from everyday life. However, the obtained results seem to be valuable as they lead to conclusions regarding biofuels, and these conclusions are not directly formulated and published in the literature on the subject. The general conclusion from the research carried out is that the introduction of the so-called biofuels can contribute not to the reduction of CO2 emissions, but to its faster balancing in the environment. This balancing can be achieved but at the cost of increased fuel consumption. This increase in fuel consumption would probably not occur if the "bio" components in the fuel were synthetic hydrocarbons obtained from biomass. However, proving it requires wider studies, including LCA. Data for this LCA, especially about a fuel consumption, may be coming from long term operation of vehicles.

Opis:
All three Baltic States have reached good figures regarding the change in total greenhouse gas emissions from transport during 1990-2017. Particularly successful is Lithuania, showing a negative value of -2.7%. Latvia considerably lags behind Estonia (+15.1% vs. +1.5%). Amid the achievement of Latvian scientists, engineers and merchants, the authors point out the work of Lithuanian engineers who investigated how gaseous hydrogen affects the parameters of diesel internal combustion engine. Important to note that in the Baltic States, the activities of inland waterway vessels and the shunting locomotives are concentrated in only a few main cities. Regarding that, Baltic scientists and environment specialists nowadays are developing plans also for local air pollution decreasing, which can be carried out in particular cities or industrial areas, thereby allowing for improvements in air cleanliness and the ecological situation in concerned local area. A numerical estimation shows that applying the NYSMART technology, introduced in this paper, will make areas of active action of the high-volume diesels cleaner in the same amount as gained by photosynthesis of the urban green flora. In recent years, the developed technology of hydraulic piston compression allows producing numerous different vehicle fueling appliances for the CNG/bio-CNG fuel. The further development of this technology means the producing of various solutions, applicable at biogas/biomethane production sites, for CNG/bio-CNG compression, transportation and fast natural gas vehicles refueling in a cost effective and convenient way. The hydraulic piston compression and NYSMART have a potential in small and medium-scale technologies and therefore need to be developed further for applications with hydrogen. Production of biomethane and green hydrogen is delayed by the lack of state aid programmes in the Baltic States. Lithuania is on the way to change the situation in the coming years, with one of the first biomethane gas production plants due to be built near Panevėžys, in Šilagalys near the Via Baltica motorway. Summing up all aspects, the preconditions for the use of alternative fuels in the Baltic States are similar, allowing one to learn from other’s experience and to consider joint projects.

Opis:
The paper presents an evaluation of the various quality parameters of biofuels used to power diesel engines and engines, including the current findings in this regard made to the Scientific Committee for the Affairs of the World Wide Fuel Charter. Characterizes the requirements for ethanol and methyl esters of fatty acids, presented in addition to the fourth edition of WWFC, published in March 2009. Characterized the basic problems of storage, distribution, and operation of FAME and ethanol as a first-generation biofuels. Also presents the basic operating conditions resulting from the research for these fuels. Presents the future prospects of biofuels for motor set in the Roadmap for Biofuels for Transport, developed by the International Energy Agency, including fuels derived from syngas, using solar energy ("solar fuels") and furan derivatives. Characterized the need for changes in the classification of biofuels and make them permanent division of conventional biofuels (previously used) and the preferred biofuels in the future - advanced biofuel. Also presents general guidelines for the biorefinery. The possibilities of performance in the application bioDME as a biofuel for diesel engines.
