“…The climate in the region ensures both solar and wind resources, being moderately high and medium, respectively. Furthermore, Central Catalonia is also a region with high on-site forest wood biomass availability [41,42], facilitating the exploitation of such a resource in a sustainable way, i.e., with minimum transportation requirements and allowing the use of only locally available resources. The township under study is Santa Coloma de Queralt, with 1271 dwellings [43], with an electricity consumption representative of that in Spanish Mediterranean climate regions [44].…”

Hybrid renewable energy systems (HRES) are a trendy alternative to enhance the renewable energy deployment worldwide. They effectively take advantage of scalability and flexibility of these energy sources, since combining two or more allows counteracting the weaknesses of a stochastic renewable energy source with the strengths of another or with the predictability of a non-renewable energy source. This work presents an optimization methodology for minimum life cycle cost of a HRES based on solar photovoltaic, wind and biomass power. Biomass power seeks to take advantage of locally available forest wood biomass in the form of wood chips to provide energy in periods when the PV and wind power generated are not enough to match the existing demand. The results show that a HRES combining the selected three sources of renewable energy could be installed in a rural township of about 1300 dwellings with an up-front investment of US $7.4 million, with a total life cycle cost of slightly more than US $30 million. Such a system would have benefits in terms of energy autonomy and environment quality improvement, as well as in term of job opportunity creation. OPEN ACCESSSustainability 2015, 7 12788

“…This biomass application is the cheapest one if compared with other biomass uses and other renewable sources: it can cost from 2 to 5 times less than other bioenergy alternative [56]. The study by Gómez et al [58] reports a range for specific investment costs that varies from 100 €/kW to 880 €/kW, with kW of thermal power contained in the flowrate of biomass used. These estimates depend on the type of coal power plant and the selected co-firing system.…”

Abstract:The electricity generation sector needs to reduce its environmental impact and dependence on fossil fuel, mainly from coal. Biomass is one of the most promising future options to produce electricity, given its potential contribution to climate change mitigation. Even though biomass is an old source of energy, it is not yet a well-established commodity. The use of biomass in large centralised systems requires the establishment of delivery channels to provide the desired feedstock with the necessary attributes, at the right time and place. In terms of time to deployment and cost of the solution, co-combustion/co-gasification of biomass and coal are presented as transition and short-medium term alternatives towards a carbon-neutral energy sector. Hence, there is a need to assess an effective introduction of co-combustion/co-gasification projects in the current electricity production share. The purpose of this work is to review recent steps in Process Systems Engineering towards bringing into reality individualised and ad-hoc solutions, by building a common but adjustable design platform to tailored approaches of biomass-based supply chains. Current solutions and the latest developments are presented and future needs under study are also identified. OPEN ACCESSEnergies 2015, 8 5614

“…These yields were obtained from studies with a comparable geographical location (Vieira et al, 2006;Fernandes and Costa, 2010;G omez et al, 2010a). An exception to this procedure was the determination of the quantity of the residual biomass collected in gardens and parks.…”

“…Also, G omez et al (2010b) referred that accurate estimates of biomass sources are needed in order to support policy decisions. Several studies have estimated the potential of different agricultural and forest residues available for energy purposes in several regions of the world (e.g., L opez- Rodríguez et al, 2009;G omez et al, 2010a;Scarlat et al, 2011;Monforti et al, 2013). Worth mentioning is the fact that estimates for the same area and biomass category may present relevant differences (see, for example, Monforti et al, 2013).…”

a b s t r a c tThe use of forest and agricultural residues for energy production presents multiple benefits, but the link between bioenergy and the environment is complex and not all of the energetic options have the same impacts. This work evaluates the net positive effect of valorizing residual biomass in the context of a rural area of Portugal, Estremoz. It focuses on the combined assessment of biomass availability, technoeconomic feasibility and environmental aspects of utilizing forest and agricultural residues to produce bioheat. At first, the energy potential of the residual biomass available in the municipality is evaluated using a geographical information system database. The assessment with RETScreen of the technoeconomic feasibility of replacing electricity by biomass for heating local public schools follows. The results show that around 27 314 t of residues, corresponding to about 267 680 GJ, are produced each year in Estremoz, more than half in montado areas. The use of this biomass for the replacement of the existing electric heating systems of nine local schools by biomass-based ones offers good project profitability. As far as the environment is concerned, the energetic valorization of the residual biomass in Estremoz has multiple benefits. It contributes to climate change mitigation by saving greenhouse gas emissions and promoting the preservation of the traditional extensive uses of the ecosystems. Moreover, a correct vegetation management decreases the fire risk, potentiates the increase in biodiversity, offers better conditions for native species and allows to maintain the ecosystems.
