Abundant, versatile, energy dense and clean at point of use, hydrogen is viewed as an increasingly important component of our future energy mix and key to the decarbonisation of our heating and transport systems.The problem is that the bulk of the hydrogen currently used is derived from fossil fuels using processes that the International Energy Authority (IEA) says is responsible for around 830 million tonnes of CO2 emissions per year.Clearly, if hydrogen is to truly deliver on its environmental potential, cleaner methods of production are going to be critical, and the winner of this year's energy and environment category ERM Dolphyn (Deepwater Offshore Local Production of HYdrogeN) offers an inspiring and highly innovative example of how that could be achieved.
