“…Therefore, the focus of this study has been the assessment of biomass potential in Greece and a state-of-the-art energy valorization case study. Biomass gasification has the advantage of high electrical efficiency in small-scale operations and provides a distinct advantage in comparison to conventional biomass combustion technologies [29][30][31]. The high efficiency, along with the extended commercial applications in Europe, have led us to consider gasification as the best-case scenario for energy valorization of biomass.…”

“…The fact that they have similar geomorphological characteristics, 48% of South Tyrol is covered by forests and only 50-60% of natural forest growth is used, with most stocks at high altitudes (78% above heights of 1.2 km), strengthens this point of view. The Italian Energy Regulatory Authority set high tariffs for the sale of energy generated in the public grid and, with other measures, have put out incentives to develop small-scale applications that are more cost-effective than large-scale ones [29][30][31]. There is a high concentration of technologies smaller than 200 kW e and some of them are deliberately smaller than 50 kW e .…”

The alignment of the Greek national legislation with the corresponding EU legislation has enhanced the national efforts to pursue renewable Combined Heat and Power (CHP) projects. The scope of the present study has been the identification of the available biomass resources and the assessment of their potential. In this paper, we present the results from the administrative regions of Crete, Thessaly, and Peloponnese. The levels of lignocellulosic biomass in Greece are estimated to be 2,132,286 tonnes on an annual basis, values that are very close to the cases of other Mediterranean countries like Italy and Portugal. In respect to the total agricultural residues, Crete produces 1,959,124 tonnes/year and Thessaly produces 1,759,457 tonnes/year. The most significant streams are identified to be olive pits, olive pruning, and cotton ginning remnants, with more than 100,000 tonnes/year each. In the latter part of this manuscript, a case study is presented for the development of a CHP gasification facility in Messenia. The biomass energy potential of the area is very promising, with about 3,800,000 GJ/year. The proposed small-scale gasification technology is expected to utilize 7956 tonnes of biomass per year and to produce 6630 MWh of electricity and 8580 MWh of thermal energy.

“…On the other hand, thermal processing of biomass and especially gasification can be a technological option with higher efficiency but also a higher cost (Alatzas et al, 2019). These aspects of thermochemical conversion for energy production have shown to be interesting for areas with a high production of forest residues (Prando et al, 2016) and favourable economic framework (Vakalis and Baratieri, 2015). The area needed for the disposing of such amounts of fertilizer is, on average, 50,000 ha.…”

Agricultural biomass can be best described as the organic matter residues from farming that remain within the fields after harvesting, along with tree trimmings. From the overall Greek Energy Balance, only a small fraction consists of biomass and this has been the main driving force behind this study. Due to the numerous ongoing agricultural activities, western Greece was selected as an ideal area for a case study. As a second step, the aim was to investigate the feasibility of the current anaerobic digestion plants to utilize the total biomass as feedstock. An additional scope to provide certifiable proof of the essential rural biomass assets available. Information on the potential of agricultural biomass is provided, with a focus on the performance specifications and the social advantages, but also the soil added substances and the produced biofuels. Subsequently, two options for waste management were discussed to illustrate the possibility of generating energy. The anaerobic digestion plants available in western Greece are illustrated in detail and the yearly rate of the main agrarian biomass is evaluated to be 715,080 tons. Arable crops, mechanical plants and tree trimming are recorded as the noteworthy sources. It is estimated that the proposed anaerobic digestion system will handle the entire amount of biomass and deliver max per year electricity 775 GWh and thermal energy 1.119 GWh.

“…India has published the biomass potential for the country, which includes the potential of the straw of cereals and pulses, stalks of fiber crops, seed coats of oil seed, and crop wastes, such as sugarcane trash, rice husk, and coconut shells (Kumar et al 2015). Furthermore, South Tyrol (Northern Italy) has declared the possibility of using Norway spruce, willow, apple logs, and apple pruning as biomass (Prando et al 2016). In Indonesia, most biomass boilers are designed to generate steam that is used in several industries for cooking processes and power plants.…”

Agricultural waste products, such as wood, rice husk, corn waste, and coconut shells, are abundantly available and can potentially be used as an energy source, particularly for direct combustion in boilers. Because coconut production increases every year, it would be useful to find an alternative use for coconut shells, which are a type of coconut waste. As coconut shells can be used as fuel in boilers, the aim of this study was to evaluate the thermal characteristics of coconut shells in this regard. This study used experimental results to evaluate the performance of a boiler when coconut shells were used as solid fuel. The variations in feed rate were 5, 7.5, and 10 kg/h, and the water flow rates varied between 1 litre per minute (lpm), 2 lpm, and 3 lpm. Temperature data were collected every second via data acquisition , and the mass flow rate of the flue gas was collected every 5 min using a pitot tube equation. One of the parameters evaluated in determining the success of coconut shells as boiler fuel is the thermal efficiency of the boiler. The results showed that the maximum thermal efficiency reached approximately 62.04%, and the maximum flue gas temperature was approximately 500 ℃ for a biomass mass flow rate of 7.5 kg/h. The maximum water temperature of the boiler was 99 ℃, which was reached at a minimum water flow rate of 1 lpm. The results showed that coconut shells are suitable for use as boiler fuel.
