Poultry farming is one of high energy consumption and energy-intensive industries that requires significant amount of fuel fossil to provide the desired internal temperature for health and production level of chicken, which results in high running cost and growth of greenhouse gas (GHG) emissions. Renewable and sustainable energy technologies are being employed in the area of poultry farming in order to achieve energy saving, GHG emission reduction and to some extent supply potential selective benefits for farmers. Therefore, it is very necessary for generalizing the state-of-the-art technologies including the solar photovoltaic, solar photovoltaic/thermal, ventilation and wind turbine, air/water/ground sources heat pump and thermal energy storage. It is demonstrated that the system energy saving could achieve up to 85% with a payback time of 3–8 years, compared to the conventional heating system.

This chapter aims to design, construct and test a new and renewable heating system for fulfilling the energy demand and ameliorating the interior environment of poultry farming in the UK. This system consists of a photovoltaic/thermal module attached to the polyethylene heat exchanger integrated with a geothermal copper pipe array and heat pump. The thermal and electrical energy performance of the hybrid renewable heating system is investigated based on a numerical model and experimental test. Moreover, the economic analysis (and environmental assessment are conducted. It is concluded that the electrical energy production from the photovoltaic array could reach 11867 kWh per annum whereas the heat pump thermal output is about 30210 kWh per annum. Meanwhile, the overall gas and electrical cost of the hybrid renewable heating system are £320 and £129, which are much less than that of the gas burners system and could save £763 and £750, respectively, resulting in less than 6-year of payback period. The energy consumption of the hybrid renewable heating system could decrease about 28873 kWh, resulting in a reduction in total CO2 emission of approximately 8.3 tons, in comparison with the gas burners system.
