Presentation on the occasion of the Workshop: Energiespeicher für die optimale Netzintegration erneuerbarer Energien in Chemnitz on October 25, 2012.
Article
This study demonstrates – based on a dynamical simulation of a global, decentralized 100% renewable electricity supply scenario – that a global climate-neutral electricity supply based on the volatile energy sources photovoltaics (PV), wind energy (onshore) and concentrated solar power (CSP) is feasible at decent cost. A central ingredient of this...
Conference Paper
The benefits of hybridising two solar technologies are not clear at first sight. Combining the low cost electricity generation by photovoltaics (PV) with the cheap thermal energy storage option available to concentrating solar thermal power (CSP) plants is what makes this package interesting. In this work we simulate hybrid power plants over the co...
Conference Paper
Ein Energieversorgungssystem mit hohen Anteilen fluktuierender Elektrizitätsquellen wie Photovoltaik (PV) und Windkraft zu entwerfen und zu betreiben ist eine Heraus-forderung. Es gibt jedoch viele Länder oder Regionen, die eine Stromversorgung aus 100 % erneuerbaren Energien (EE) anstreben: die Cookinseln, Costa Rica, Dominica, Fidschi, die Maledi...
Conference Paper
Rural electrification is a crucial factor for the development of countries globally. A lack of access to an electricity transmission and distribution grid due to a remote location leads to a widespread use of diesel generators to produce electricity. This is cost-intensive and leads to high CO2 emissions. The present paper summarizes the results of...
Conference Paper
Mini-grids with high shares of renewable energies usually require energy storage systems based on technological and economic reasons. According to natural conditions battery storage is often the only applicable storage technology and thus hybrid mini-grids can be considered as very attractive niche market in substitution of diesel mini-grids. Unfor...

Conference Paper
In a climate change constraint world, it is of utmost relevance that energy technologies offer a low level of greenhouse gas (GHG) emissions at a comparatively low cost level. We give an overview which clearly documents that the common view on PV systems clearly deprives the PV technology that status. However, only less research is available and mo...

Nearly all of the about 80% of Ethiopians living in rural areas have no access to electricity. Excellent solar conditions enable attractive small off-grid PV systems for rural population. Their today's energy budget allows short payback periods of only about 2 to 4 years. As a consequence of high oil prices, even larger PV systems are very competit...

Emitter wrap through solar cells (EWT) are known for exhibiting low fill factors (FF). In this contribution we explain the FF losses by a three-dimensional EWT simulation model. The origin of reduced FF of EWT solar cells can be explained by Via-resistance Induced Recombination Enhancement (VIRE-effect). A voltage drop along the EWT-via emitter enh...

... It is noticeable that especially NGOs tend to deal with longer timeframes than other stakeholder groups. Furthermore, we find that stakeholders also need demand modelling results at shorter time resolutions, as sector coupling, fuel swapping in final energy uses, and modifications in efficiency will lead to changes in the future demand profiles; not only in terms of absolute numbers but also in their shape [51,52]. This seems of specific interest to actors from industry and partly scientists. ...
... Recently, researchers developed several large-scale energy storage techniques [9], virtual power plants [10] and demand-side management methods [11] to improve the flexibility of power systems [2]. Besides, considering that the huge amount of water in district heating networks (DHNs) has an ability to store heat to improve the adjustability of CHP plants and that there is no extra initial investment for utilization of the existing DHNs [12][13][14], some researchers paid attention to the application of the passive heat storage capacity of DHNs. ...
... In our systemic analysis we study the fundamental structure of transforming an energy system from 0 % to 100 % renewable energy. The details of that analysis are discussed elsewhere [61]. ...
... Structural characteristics of renewable energy technologies fit well to fundamental requirements of energy technologies in the 21 st century: low greenhouse gas (GHG) emissions, high energy yield factors for a fast substitution of today's not sustainable technologies, i.e. short energy payback times (EPBT), stable energy learning rate, turning from GHG avoidance costs to benefits and pathways to reach a sustainable low cost level. PV well fulfils these requirements: GHG emissions are between 15 -45 gCO 2eq /kWh [61][62][63][64], energy yield factors are between 10 -30 due to a EPBT of 0.8 to 2.5 years [61][62][63][64], energy learning rate is about 14% for PV systems [65] and financial benefits and cost for avoiding GHG emissions range between benefits of about 400 €/tCO 2eq and costs of slightly less than 90 €/tCO 2eq [66] and fast declining LCOE (section 3.1 and 4). ...
... In contrast, isolated renewable energy (RE) systems have proven to be a very appropriate alternative in remote rural areas, as recommended by a large number of authors, i.e. [17][18][19][20][21][22]. The most relevant advantages of these systems are: the use of local resources in preventing costly transmission losses [23], the appropriateness for installations with low load factors [24], the prevention of dependency on fossil fuel supplies [25] and the promotion of energy independence in the population [26,27]. ...
... The recent tendency is the use of selective emitters and of MWT [157,158] as well as EWT [159] metallization techniques. The most impressive recent results come from Japan and from China. ...
... Regarding dispatching strategy of a PV-CSP system, Zhai et al. [19] proposes a technoeconomic analysis of a PV-CSP system in two dispatch strategies; the strategy that prioritizes the use of PV during the day and CSP during the night is more profitable than the strategy that operates PV and CSP independently. All studies confirm that the use of a PV-CSP system associated with thermal storage may achieve a high capacity factor and can provide more economical production in a long time comparing with a PV or a CSP plant, for all location of studies [19][20][21]. ...
... One of the main streams of literature correspond to studying P2G storage options as a mean to capture high renewable electricity production. (Moeller et al., 2014) show that P2G is a main part of a cost optimal energy system with renewable energy shares above 75%. However, (Kötter et al., 2016) show that a 100% renewable energy system can be realised with or without P2G as it is possible to use batteries. ...
... This means that 75% of Ugandans will not rely on grid connectivity for the provision of energy. Off-grid based RE solutions like mini-grids, and in particular solar home systems (SHS) provide a least cost solution for realizing the full electrification of rural people in Sub-Saharan Africa [11,12,17,6,81]. PVbased mini-grids can be established for initial electrification but also for upgrading existing and costly off-grid diesel-grids [16]. ...
