Hydrogen, an abundant and simple element on Earth, presents a hugely attractive fuel option as it is high in energy and its by-product of combustion is water, meaning that when compared to traditional hydrocarbon sources of fuel it can truly be described as a clean alternative. Important scientific strides have been made in the conversion of hydrogen into electricity while the hydrogen fuel cell remains a hot topic of discussion in some circles. US CleanTech are focused on hydrogen science and developing innovative technologies and solutions that can efficiently exploit the potential of hydrogen energy.

With hydrogen we can imagine a future with the potential to create a clean, sustainable fuel. Hydrogen does not occur naturally and therefore needs to be created and subsequently stored as a fuel, which can then be converted to energy via hydrogen fuel cells.Excitingly it is possible to create hydrogen from solely renewable resources with the environmental impact rated as low to negligible. There are however a number of obstacles must be overcome for this hydrogen future to be realised principally regarding safe and efficient storage. Logistical issues are also associated with implementation of hydrogen as a widely used fuel source, the ultimate goal is to carry hydrogen as a liquid, as cars running on fuel cells could employ existing liquid fuel infrastructure.

Solar-to-Hydrogen Conversion technology

The focus on pathways to reduce the use of fossil fuels in the transport sector is intense in many countries worldwide. Considering that biofuels have a limited technical production potential and that battery electric vehicles suffer from technical limitations that put constraints on their general use in the transport sector, hydrogen-fuelled fuel cell vehicles may become a feasible alternative. Introduction of hydrogen in the transport sector will also transform the energy sector and create new interactions as a result we continually monitor the emerging developments and opportunities in this field.
