“…Many researchers have suggested that micro hydro is one of the most environmentally benign energy conversion options available because it does not interfere significantly with river flows (Fraenkel et al, 1991;Mishra et al, 2011). Yet environmental managers in the UK see microhydro power as a massive contemporary issue (Cussens, Natural England, pers.…”

Department of Geography, Durham University, Durham, DH1 3TE AbstractResearch around micro-hydro power is focused on technical aspects with limited understanding of the social organisation and environmental implications. We examine the ways in which microhydro is engaged by people and organisations as a means of contributing to the UK's policy ambition for renewable energy. We bring to the fore the way in which expertise is used and contested. A web based review of micro-hydro schemes in the UK was undertaken and a detailed evaluation of two schemes in the North of England was conducted to determine how expertise and contestation figures in community schemes. Results demonstrate a rapid expansion of micro-hydro in the UK. Ownership/control is highly 'community based'. Until now research around micro-hydro has been dominated by technical approaches with schemes defined in terms of hardware. We propose a third dimension to Walker and Cass's (2007) classification of renewable energy developments: the environmental dimension. We suggest this dimension of micro-hydro is critical, both in terms of the extent to which resources can be realised but also the ways in which it might attract controversy, in particular around how expertise is used and valued.

“…Furthermore, a World Bank study in 2006 showed that pico-hydropower is the most competitive offgrid power technology on a levelized cost of electricity (LCOE) basis ($/kWh), as shown in Fig. 1 [3,4]. In Rwanda for example, the national utility retail price for electricity in 2009 was $0.24/kWh [5], yet pico-hydro is estimated to cost less than $0.20/kWh.…”

An experimental investigation of design parameters for pico-hydro Turgo turbines using a response surface methodology

et al. 2016

a b s t r a c tMillions of off-grid homes in remote areas around the world have access to pico-hydro (5 kW or less) resources that are undeveloped due to prohibitive installed costs ($/kW). The Turgo turbine, a hydroelectric impulse turbine generally suited for medium to high head applications, has gained renewed attention in research due to its potential applicability to such sites. Nevertheless, published literature about the Turgo turbine is limited and indicates that current theory and experimental knowledge do not adequately explain the effects of certain design parameters, such as nozzle diameter, jet inlet angle, number of blades, and blade speed on the turbine's efficiency. In this study, these parameters are used in a three-level (3 4 ) central composite response surface experiment. A low-cost Turgo turbine is built and tested from readily available materials and a second order regression model is developed to predict its efficiency as a function of each parameter above and their interactions. The effects of blade orientation angle and jet impact location on efficiency are also investigated and experimentally found to be of relatively little significance to the turbine. The purpose of this study is to establish empirical design guidelines that enable small hydroelectric manufacturers and individuals to design low-cost efficient Turgo Turbines that can be optimized to a specific pico-hydro site. The results are also expressed in dimensionless parameters to allow for potential scaling to larger systems and manufacturers.
