Around the world organisations are changing to zero carbon energy obtained from renewable sources or recycled organic waste. Electrochemical energy conversion with fuel cells is two or three times more efficient than combustion and there are no other emissions of nitrogen oxides or particulate matter.
Fuel Cell Power Spring 2021 illustrates applications in double decker buses, trains, marine vessels, a passenger plane in local flight, cars, service vehicles, unmanned aerial vehicles (UAVs) and providing combined heat and power (CHP) for buildings and industry.
Engineers concerned about air pollution and climate change have been working for decades to make zero emission fuel cells available but there has been little interest from established industries which are backed by governments. There is now growing demand for cost effective zero emission energy systems both in advanced and developing countries and international programmes are essential to make fuel cells available.
