  • The Role and Status of Hydrogen and Fuel Cells Across the Global Energy System
    The role and status of hydrogen and fuel cells across the global energy system Iain Staffell(a), Daniel Scamman(b), Anthony Velazquez Abad(b), Paul Balcombe(c), Paul E. Dodds(b), Paul Ekins(b), Nilay Shah(d) and Kate R. Ward(a). (a) Centre for Environmental Policy, Imperial College London, London SW7 1NE. (b) UCL Institute for Sustainable Resources, University College London, London WC1H 0NN. (c) Sustainable Gas Institute, Imperial College London, SW7 1NA. (d) Centre for Process Systems Engineering, Dept of Chemical Engineering, Imperial College London, London SW7 2AZ. Abstract Hydrogen technologies have experienced cycles of excessive expectations followed by disillusion. Nonetheless, a growing body of evidence suggests these technologies form an attractive option for the deep decarbonisation of global energy systems, and that recent improvements in their cost and performance point towards economic viability as well. This paper is a comprehensive review of the potential role that hydrogen could play in the provision of electricity, heat, industry, transport and energy storage in a low-carbon energy system, and an assessment of the status of hydrogen in being able to fulfil that potential. The picture that emerges is one of qualified promise: hydrogen is well established in certain niches such as forklift trucks, while mainstream applications are now forthcoming. Hydrogen vehicles are available commercially in several countries, and 225,000 fuel cell home heating systems have been sold. This represents a step change from the situation of only five years ago. This review shows that challenges around cost and performance remain, and considerable improvements are still required for hydrogen to become truly competitive.

  • Hydrogen Storage for Mobility: a Review
    materials Review Hydrogen Storage for Mobility: A Review Etienne Rivard * , Michel Trudeau and Karim Zaghib * Centre of Excellence in Transportation Electrification and Energy Storage, Hydro-Quebec, 1806, boul. Lionel-Boulet, Varennes J3X 1S1, Canada; [email protected] * Correspondence: [email protected] (E.R.); [email protected] (K.Z.) Received: 18 April 2019; Accepted: 11 June 2019; Published: 19 June 2019 Abstract: Numerous reviews on hydrogen storage have previously been published. However, most of these reviews deal either exclusively with storage materials or the global hydrogen economy. This paper presents a review of hydrogen storage systems that are relevant for mobility applications. The ideal storage medium should allow high volumetric and gravimetric energy densities, quick uptake and release of fuel, operation at room temperatures and atmospheric pressure, safe use, and balanced cost-effectiveness. All current hydrogen storage technologies have significant drawbacks, including complex thermal management systems, boil-off, poor efficiency, expensive catalysts, stability issues, slow response rates, high operating pressures, low energy densities, and risks of violent and uncontrolled spontaneous reactions. While not perfect, the current leading industry standard of compressed hydrogen offers a functional solution and demonstrates a storage option for mobility compared to other technologies. Keywords: hydrogen mobility; hydrogen storage; storage systems assessment; Kubas-type hydrogen storage; hydrogen economy 1. Introduction According to the Intergovernmental Panel on Climate Change (IPCC), it is almost certain that the unusually fast global warming is a direct result of human activity [1]. The resulting climate change is linked to significant environmental impacts that are connected to the disappearance of animal species [2,3], decreased agricultural yield [4–6], increasingly frequent extreme weather events [7,8], human migration [9–11], and conflicts [12–14].

It is demonstrated that perforation of graphene sheets results in increase of theoretically possible surface areas beyond the limits of ideal defect-free graphene (~2700 m2/g) with the values approaching ~5000 m2/g. This in turn implies promising hydrogen storage capacities up to 6.5 wt% at 77 K, estimated from classical Grand canonical Monte Carlo simulations.

  • Comparison of Hydrogen Powertrains with the Battery Powered Electric Vehicle and Investigation of Small-Scale Local Hydrogen Production Using Renewable Energy
    Review Comparison of Hydrogen Powertrains with the Battery Powered Electric Vehicle and Investigation of Small-Scale Local Hydrogen Production Using Renewable Energy Michael Handwerker 1,2,*, Jörg Wellnitz 1,2 and Hormoz Marzbani 2 1 Faculty of Mechanical Engineering, University of Applied Sciences Ingolstadt, Esplanade 10, 85049 Ingolstadt, Germany; [email protected] 2 Royal Melbourne Institute of Technology, School of Engineering, Plenty Road, Bundoora, VIC 3083, Australia; [email protected] * Correspondence: [email protected] Abstract: Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency Citation: Handwerker, M.; Wellnitz, and high prices for the required components, this domestically produced hydrogen cannot compete J.; Marzbani, H. Comparison of with hydrogen produced from fossil fuels on a larger scale.
