Biomass is a promising alternative energy source for fossil fuel with the advantages of abundance, renewability, environmental friendliness, etc. This makes the development of biomass technology be of great potential and interesting. The experiments of biomass fast pyrolysis were performed in a microquartz reactor for rice husk (RH), corn stalk (CS) and birch wood (BW), and scanning electron microscope (SEM), energy dispersive spectrometer, and Raman microscope were then applied to analyze the collected chars. The average char yields of RH, CS, and BW pyrolyzed at 800 °C were 29.64%, 18.67%, and 8.64%, respectively. The morphological structures of RH and CS were mainly reserved in chars, while the raw surface textures of BW disappeared during the fast pyrolysis. The silicon concentrations in RH char and CS char were much higher than BW char, and the graphitization degree of CS char was the lowest among the three biomass chars.

Current State

Gas hydrates are considered a global phenomenon that, as an unconventional fossil fuel, can be an alternative energy source for the future. Hydrates form spontaneously in permafrosts and marine sediments, where the conditions for their formation are naturally suitable - low temperature and high pressure. The energy of hydrates could replace or supplement the most commonly used fossil fuels today. Hydrates are also an advantageous solution to the problem of natural gas storage. The main part of the experimental equipment operated is a pump, which generates the pressure energy needed to form hydrates. The article deals with the assessment of the effectiveness of the current state and the estimation of losses in the pipelines of the facility.

ABSTRACTThe inadequate sources of energy coupled with the increasing demands of power have necessitated the search for novel renewable energy resources. ‘Phumdis’ are one such promising alternative. Phumdis are floating mats of heterogeneous mass of vegetation, soil and organic matter found in Loktak Lake in Manipur, North Eastern India. This paper delineates the use of Phumdis as an alternative energy source. Phumdis from Loktak Lake, Manipur were processed and analyzed for their biofuel capabilities. The Results indicate that the phumdis have high calorific content, cloudpoint and flash point indicating that they are at par with other fuels.

The article deals with the application of pellets as an alternative fuel for the automotive gasifier. In internal combustion engines as fuel it is possible to use producer gas generated by gasifier operating on wood waste (pellets). Cars running on wood gas (also called gas cars), though losing its elegance in appearance, but very effective in terms of environmental friendliness and can be with electric cars.

Eco-friendly technologies involved making use of alternative energy source which is abundant to generate renewable energy, reducing the amount of resource which is limited used through the conventional like fossil fuel.  For example renewable resources like sunlight, sea water and co2 which are abundant generating alternative resource like biofuel, solar energy, freshwater and air purification through greenhouse, vegetation and halophytes cultivation stabilize the degraded desert soil and as wind breaks reduce the impact of pollutants on the environment.

Concerns about climate change and fossil fuel shortages are encouraging interest in stumps, as alternative energy sources. Stumps are an almost unused resource in the context of bio fuels. Stump harvesting signifies an intensification of forest management compared with conventional stem-only or above-ground biomass-only harvesting. There are many benefits of stump harvesting. These include: the production of wood fuel, fossil fuel substitution, and improved soil preparation.Removing tree trunks in Hungary has been going on according to the principle of stump extraction, which means stumps are removed by grabbing technology. Experiments have been carried out to reduce the extraction force. In the Great Hungarian Lowland, where large areas require the operation implementation, stump extraction is done by special, hydraulic driven baggers equipped with a special bucket. During operation of the equipment, we carried out measurements of the extraction force and the time requirement. The experiments are designed to carry out the measurements with different soils and different tree species. According to our proposal the suitable force and torque required to remove stumps can be significantly reduced if before the lifting the soil — root connection is loosened. One of the possible ways to implement this task is the use of vibration. Since relatively great vibration power and wide domain of frequency are necessary, therefore we prepared the loosening machinery elements of alternating-current hydraulics system. Based on constructions variants we created a tractor-mounted experimental alternating-current hydraulic stump-loosening machine. It was designed with the ability to produce horizontal vibration in order to loosen stumps.
