European Biomass Conference and Exhibition Proceedings | Year: 2016

Small modular district heating/cooling grids can be fed by different heat sources, including solar collectors, biomass systems and surplus heat sources (e.g. heat from industrial processes or biogas plants that is not yet used). Especially the combination of solar heating and biomass heating is a very promising strategy for smaller rural communities due to its contribution to security of supply, price stability, local economic development, local employment, etc. On the one hand, solar heating requires no fuel and on the other hand biomass heating can store energy and release it during winter when there is less solar heat available. Thereby, heat storage (buffer tanks for short-term storage and seasonal tanks/basins for long-term storage) needs to be integrated. With increasing shares of fluctuating renewable electricity production (PV, wind), the Power-to-Heat conversion through heat pumps can furthermore help to balance the power grid. The objective of the CoolHeating project, funded by the EU’s Horizon2020 programme, is to support the implementation of "small modular renewable heating and cooling grids" for communities in South-Eastern Europe. © 2016 ETA-Florence Renewable Energies.

European Biomass Conference and Exhibition Proceedings | Year: 2016

In Europe the demand of biomass for the whole bioeconomy is increasing year by year. In some cases, this biomass come from non-European countries. The EU is already a net importer of biomass for bioenergy and imports could be even more relevant in the near future. Therefore, it is important to guarantee that this biomass supply from outside the EU is being done in a sustainable way and that negative environmental and socio-economic impacts are minimised. The project BioTrade2020plus has the aim of providing guidelines for the development of a European Bioenergy Trade Strategy for 2020 and beyond. It has analyzed in depth the role of lignocellulosic biomass (woody resources, agricultural residues and cellulosic crops) imports from six selected sourcing regions: North America (Southeast United States), South America (Brazil, Colombia), East Europe (Ukraine), Southeast Asia (Indonesia) and East Africa (Kenya). It has considered availability and sustainability constrains as well as existing strategies in these sourcing regions. All this info is being integrated in an interactive tool available on the BioTrade2020plus webpage. © 2016 ETA-Florence Renewable Energies.

European Biomass Conference and Exhibition Proceedings | Year: 2016

The purpose of this work is to promote the use of unexploited food waste as feedstock for biomethane production in Europe.In the EU around 90 million tonnes of food waste are produced annually, or around 180 kg/person. Although the use of food waste for biogas production has multiple benefits, 40% of bio-waste in the EU still goes to landfills. In some Member States this waste is almost completely landfilled. An estimation is that about one-third of Europe`s 2020 targets for renewable energy in transport could be met by using biogas produced from bio-waste (including food waste), and around 2% of the EU`s overall renewable energy target could be met if all biowaste were turned into energy.Modern and environmentally friendly waste management is still not introduced in many European cities and regions. This problem is tackled by the Bin2Grid project which promotes the “food waste to biomethane” concept in four large European cities in order to serve as flagship examples for other cities.The objective of the Bin2Grid project is to support biomethane production and its use in transport by using segregated food waste from the food and beverage industry, catering sector, and from households as feedstock. Focus of the Bin2Grid project is on the development of value chain concepts for four European cities: Zagreb (Croatia), Skopje (Macedonia), Malaga (Spain), and Paris (France). The Bin2Grid project highlights the multiple environmental benefits of source-separate waste collection and conversion of that feedstock into biomethane, in comparison to other treatment methods (landfilling, incineration, MBT, composting). A Benchmark Tool as well as an economic calculation tool was developed by the project and is presented in this paper. © 2016 ETA-Florence Renewable Energies.

Progress in Photovoltaics: Research and Applications | Year: 2016

The establishment of new photovoltaic (PV) markets in emerging economies represents a business development opportunity for expansion outside traditional energy markets. Appropriate assessment of PV market competitiveness is thus necessary in order to inform policy and regulatory development, and in order to manage risks related to investment. This paper presents an evaluation of PV energy competitiveness using a case study of the emerging residential PV market in South Africa. Competitiveness is defined in light of the risks associated with the financial performance of domestic grid-connected rooftop PV considering the current market status together with three proposed business models, namely net-metering, net-billing and an energy savings performance contract framework. Financial performance is evaluated in terms of a socket parity evaluation together with a discounted net cash flow analysis. Investment risk assessment was facilitated using a Monte Carlo simulation. The results indicate the highest potential profitability for the energy savings performance contract model, which includes PV system ownership by an energy services company. It is also shown that appropriate application of risk modelling has the potential to inform decisions by investors and policy makers alike that result in improved policy and business solutions that are able to support increased residential PV energy market competitiveness without the need for explicit subsidy frameworks.

Energy Procedia | Year: 2017

This paper reviews the present status and outlook of the building integrated photovoltaics (BIPV) market on a global and European scale. In particular, it provides a comprehensive review of the market situation and the future trends for Austria, Cyprus, France, Germany, Italy and the Netherlands until the year 2020. In addition, as education is seen as one of the barriers for BIPV deployment, results of a survey are presented that was conducted among BIPV stakeholders with the aim to identify major knowledge gaps in education and target audiences as well as teaching goals. From that potential courses dedicated to the needs of each target audience related to BIPV can be developed. © 2017 The Authors.

Ambitious targets have been set by the EU Directive 2009/28/EC and the high renewable energy scenario presented in Energy Roadmap 2050 by the European Commission. In order to reach these targets it is required detailed analysis on the competitiveness of photovoltaics (PV) electricity. The PV PARITY project, which is supported by the European Commission in the frame of the Intelligent Energy for Europe programme, scopes to provide the necessary support to the policy-makers in order to ensure a sustainable policy framework for the PV sector. Its main tasks are: (i) definition of PV competitiveness; (ii) roadmaps to PV grid parity; (iii) definition of the relevance of PV electricity import from Middle East and North Africa (MENA) countries; and (iv) cost/benefits of the PV network integration. The current paper presents briefly the main methodology putting emphasis on the role of MENA countries in the PV competitiveness. © 2013 Taylor & Francis.

Energy and Buildings | Year: 2016

This paper highlights the potential of adapting the energy profile of conventional office buildings in Southern Europe into a profile of Balanced Energy Buildings. The proposed energy adaptation does not only aim to satisfy the electricity consumption on an overall annual basis using intermittent renewable energy sources (RES), but seeks for a better instantaneous match of the on-site demand of the building with the production from RES. The self-consumption of locally generated clean electricity shall be maximized and peaks in energy transactions between building and grid are to be reduced. The aforementioned targets are pursued with the utilisation of intermittent RES (mainly solar PV systems in Southern Europe), active energy-saving techniques supported by ICT (Information & Communication Technology) technologies and energy storage systems. Beyond this, attention is given to the indoor climate comfort. © 2016 Elsevier B.V. All rights reserved.

Desalination and Water Treatment | Year: 2012

The balance between water demand and availability has reached a critical level in many areas of Europe, the result of over-abstraction and prolonged periods of low rainfall or drought. Desalination of seawater and brackish water is one of the alternatives for ensuring a reliably supply of drinking water. Renewable energy sources (RES) coupled to desalination offers a promising prospect for covering the fundamental needs of power and water. Various initiatives and projects over the past few years have been covering the field of RE-desalination. The project entitled "Promotion of RES for Water Production through Desalination, ProDes" started on the 1st of October 2008 and it will run for two years. The ProDes project has been carefully designed in order to build on the past and exiting efforts and coordinate its activities with them in order to maximize the expected outcomes. The present paper presents the first results of the project and its general progress. © 2012 Desalination Publications.

Biofuels, Bioproducts and Biorefining | Year: 2013

Second-generation biofuel production facilities have been slower to reach large-scale production than was anticipated a few years ago even though in Europe, the Renewable Energy Directive provides incentives; in the United States there are also financial incentives and the Energy Independence and Security Act of 2007 has targets for second-generation biofuels. But starting in 2013 it appears that significant quantities of second-generation biofuels will be produced. A variety of conversion processes, thermochemical and biological, as well as hybrids of the two is being utilized. There will be a variety of fuels - ethanol, drop-in fuels (e.g. gasoline, diesel), biodiesel, steam, electricity, bio-oil, sugars, and chemicals; and a variety of feedstocks - crop residues, wood, wood wastes, energy crops, waste oils and municipal solid waste (MSW). One approach to reducing the risk of moving from first- to second-generation biofuel production has been to take incremental steps such as converting the cellulosic part of grains into ethanol in addition to the starch portion. Many of the second-generation biofuel facilities are co-located with first-generation biofuel production facilities to share infrastructure as well as trade by-products (e.g. excess steam). One of the challenges has been financing, but both private and government sources are being utilized. Private sources include internal corporate funds and debt offerings, and venture capital. Government sources include the US federal government, the European Union, European national governments, and state and local governments. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd.
