atteries but are different in that they require a continuous source of fuel and oxygen or air to sustain the chemical reaction, whereas in a battery, the chemicals present react with each other to generate electricity. Fuel cells can produce electricity continuously for as long as these inputs are supplied. There are many types, but all comprise anode, cathode, and electrolyte that allow positively charged hydrogen ions (or protons) to move between the two sides of the fuel cell. As by-products, fuel cells produce water, heat and only very small amounts of nitrogen oxides and other emissions. So they are very clean, and the efficiency is also high, at around 40 – 60% (up to 85% efficient if waste heat is captured for use). The fuel cell market is growing, and Pike Research (via Wikipedia) has estimated that the stationary fuel cell market will reach 50GW by 2020. A big advantage is the technology’s use of hydrogen, which will never run out, but other advantages include cleanliness, high power output and they need little maintenance. However, the disadvantages are that to separate the atoms of the hydrogen and oxygen and generate hydrogen fuel, fossil fuels are needed. This defeats the purpose of an alternative <strong>energy</strong> source at least partially. Also, while fuel cells are non-toxic, there is a flammability (and even explosion) risk, and they are also expensive to make. The effect of the ‘Internet of Things’ There is one technology, which while again is not sustainable in itself, is becoming so fast growing and important that it must be mentioned here. That is the Internet of Things (IoT). The IoT is the network of physical objects or ‘things’ embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. The IoT will lead to automation in nearly all fields, including of course, heating, ventilation, smart meters - and all things sustainable as well. ■ Fuel cells are very clean, and the efficiency is also high, at around 40 – 60% (up to 85% efficient if waste heat is captured for use).
