Geothermal power is a rapidly developing form of renewable energy, where heat is harvested directly from the Earth’s crust. One potentially abundant source of this energy is water in disused coal mines, which absorbs heat from the surrounding rock. There are thousands of these mines throughout Britain. With the right approach, Durham Energy Institute estimates that there is enough energy within them to meet the heating demands of every building lying over the coalfields. If achieved, this goal would not only be a significant step towards decarbonising the British economy; it could also provide immense benefits to disadvantaged former mining communities in the region.

Reinforced concrete is a cheap and versatile material that combines the high compressive strength of concrete with the ability to resist stress provided by embedded steel bars. While reinforced concrete can be highly durable, exposure to harsh environments can reduce its lifetime. One of the main threats is the corrosion of the steel bars, which causes solid oxides to build up. As these oxides build up, they put pressure on the concrete, causing cracks to form and grow. Over time, pieces of the outer concrete layer can flake off or separate. As the steel corrodes, it no longer sticks well to the surrounding concrete, and the metal bars become thinner. If left untreated, this can weaken the structure.
