Analysis of ground-source heat pumps in north-of-England homes

YesThe performance of Ground Source Heat Pump (GSHP) systems for domestic use is an increasing area of study in the UK. This paper examines the thermal performance of three bespoke shallow horizontal GSHP systems installed in newly built residential houses in the North of England against a control house which was fitted with a standard gas boiler. A total of 350 metres of High Density Polyethylene pipe with an external diameter of 40 mm was used for each house as a heat pump loop. The study investigated (i) the performance of a single loop horizontal Ground Heat Exchanger (GHE) against a double loop GHE and (ii) rainfall effects on heat extraction by comparing a system with an infiltration trench connected to roof drainage against a system without an infiltration trench above the ground loops. Parameters monitored for a full year from October 2013 to September 2014. Using the double GHE has shown an enhanced performance of up to 20% compared with single GHE. The infiltration trench is found to improve performance of the heat pumps; the double loop GHE system with an infiltration trench had a COP 5% higher than that of the double loop GHE system without a trench

Fighting the Pipe: Neoliberal Governance and Barriers to Effective Community Participation in Energy Infrastructure Planning

Development of effective participatory mechanisms within infrastructure planning governance has been dependent on how far the outputs of participatory processes have an impact upon strategic policy priorities. However, neoliberal modes of governance are characterised by ‘recentralisation’ within arms-length regulatory bodies and private corporations. Tensions between participatory governance and recentralisation are exemplified by the relationship between energy privatisation and energy infrastructure planning. With this study we examine these tensions using a case study of a critical infrastructure project in the UK, the South Wales Gas Pipeline. Findings confirm arguments in the literature that siting conflicts often centre on policy issues as much as local concerns. The study reveals that the neoliberal recentralisation of some governance functions exacerbates such conflicts. We argue that, although new efforts to secure effective participation in neoliberal regimes are necessary, they will face obstacles in the form of risk-based governance structures, as exemplified by the privatised energy sector

Energy Business in Gambia: An Industry Review for Theoretical and Practical Implications

Based on the case study approach, this chapter precises the structural foundation of the Gambian energy sector to understand how the sector has become a key contributor of the Gambian economy. However, the sector encounters significant socio-economic challenges, the Gambian government’s revitalization policy has appeared instrumental to encounter the challenges. Following the recent trade and service liberalization policy, the energy sector, which has been very narrow for many years, in terms of its governance structure and contribution to the economy, is now moving positively forward with continuous investment opportunities. Private sector investment and further energy market development positively impact on the growth of the sector to help reducing the challenges of insecurity and unemployment in Gambia. The theoretical implications of this revitalization policy are discussed
