It can be argued that Wales is at the very forefront of the shift from traditional fossil fuels into renewable energy, with many large scale projects to tackle large scale energy delivery capacities.
Wales is home to the second largest wind farm in the world, which currently generates enough low carbon electricity to power over 400,000 homes. Due to its success, further turbines are being added to the network both offshore and inland to increase generation levels. Tidal energy projects are also underway along with thousands of other ground breaking ventures to continue to build upon the energy efficiency and power generation of the nation.
So how can coal mine water heat homes? The principles are quite simple really. Warm water is pumped from the mine and does through a heat exchanger which is fitted in each home. The heat from the heat exchanger is passed through the heat pump and warms the water in the central heating system. As the water from the coal mine does not enter into the central heating system, it can be pumped back underground into the mine where it will heat back up again.
Ironically, this clean source of reusable energy is being drawn as a direct of the fossil fuel that was once mined there, which seems to be a key factor in being able to gain access to the water approximately 750ft underground.
This scheme is projected to save each household around £100 per year as gas isn’t required to heat the water. Described as the fifth most deprived ward, the energy savings made to each household could aid in the reduction of fuel poverty whilst also continuing to make Wales even more greener.
