Alternative energy sources
Alternative energy sources (AES) represent a dynamically developing segment of the energy sector based on diverse and often innovative technologies that (thanks to public support) replace conventional sources and forms of energy associated with varying reliability, energy efficiency and costs. In accord with this concept, there is also a wide range of services that we offer in this area, starting with advice for developing new policies and legislation, through independent verification of the feasibility or the technical-economic parameters of the various solutions under consideration up to technical assistance for investors preparing specific projects (focusing on the production of electricity and/or heat or other forms of energy, such as alternative fuels).
In our services, we primarily try to find solutions which will improve the overall benefits of using AES and at the same time have equal or better and lower economic costs. As a result, we place great emphasis on the highest possible energy efficiency within the transformation processes associated with their use.
Apart from renewable energy sources (RES) we are also involved with secondary sources, in particular waste, the use of which can under certain conditions have even greater environmental benefits and still be (much) cheaper. In general, we prefer such solutions, because at the same time they contribute to economic development and involve other attendant effects.
Last but not least, we also are interested in alternative energy sources in transportation. Up to the present, their wider application has many significant questions. Nevertheless, the aim of our company is gradually to help remove them though various ways (expert opinions, studies, etc.). An example is CNG, whose environmental benefits can be further strengthened by the addition of biomethane obtained from suitable organic materials (waste).
Analysis of the benefi ts and costs of the operational support for renewable heat implementation
The detailed analysis evaluates the benefits and costs associated with the proposed introduction of operational support for heat production from renewable sources (which was incorporated into the text of the new law on promoted energy sources debated by the Parliament of the Czech Republic in the second half of 2011). The purpose of the introduction of operational support for heat is to strengthen the competitiveness of solid biomass use in the heating plants (i.e. energy efficient and generally less costly) which, due to the introduction of system support of electricity production, lags behind the competitive prices offered by major sources that use biomass fuels in the form of biomass co-incineration for primary production. The introduction of such support would also help in meeting the new development objectives of the country by 2020, which will newly include heat and fuels designed for final consumption (including transport). The current rate of effective use of energy from biomass fuels is relatively low, owing to the widespread burning in condensing power plants, and the targeted support for heat production could help to correct this negative trend. It would then also increase the supply of biomass fuels on the market (thanks to its ability to also use the more expensive alternatives).
Renewable energy source for a central heat source in Bechyně
The project concerns the construction of a biomass boiler in the heat management system of the town of Bechyně, in which biomass combustion makes up 80% of total heat production. Part of the project is the technological connection of two separate heat sources. An energy audit was compiled within this project, which forms an annex to the grant application from the Operational Programme Enterprise and Innovation 2007-2013 ECO-ENERGY.
Biomass Action Plan – energy and technological use of biomass
The Ministry of Agriculture of the Czech Republic has decided to update the Biomass Action Plan for the Czech Republic (hereinafter referred to as the “BAP”), whose first version was drafted in 2007 and is valid for the years 2008 to 2010. The area of energy and technological use of biomass is a very important part of the Action Plan, and SEVEn, as one of the team members, was delegated the task of its preparation. The goal of SEVEn’s contribution was to assess the different ways of primary energy conversion in organic matter into usable forms of energy and, at the same time, to recommend the further development of the sector with regard to the potential of various available forms of biomass. The recommendations confirmed the need in future policy for a clear preference for waste and by-products of agricultural and food production whose use is not in conflict with food security yet provides an interesting potential exploitable at reasonable economic costs. At the same time, the priority should be given to increasing the efficiency of conversion processes, which currently often lags far behind the possibilities of contemporary technologies.
