  • Hydrogen Trains – an Effective Alternative to Rail Electrification?
    HYDROGEN TRAINS – AN EFFECTIVE ALTERNATIVE TO RAIL ELECTRIFICATION? Tuesday 22 May 2018, Edinburgh Conclusions Hydrogen is increasingly being used as an energy vector in transport. The Workshop examined these applications and looked at the use of hydrogen, fuel cells for trains as an alternative to electrification. The Workshop concentrated predominantly on regional trains and drew attendees from the hydrogen and rail industries in roughly equal numbers. Policymakers from different tiers of government were also represented. Some participants came from mainland EU and Canada but the majority of participants were from the UK. Policy Developments • Alternative solutions to diesel trains are needed so that the rail sector can comply with energy and environmental policies and decarbonise the rail network. • The European Commission will continue to encourage cleaner fuels, both through "carrots" such as funding for research (including the Fuel Cell Hydrogen Joint Undertaking which is 50% funded by EU money) and "sticks" such as legislative requirements for clean fuels infrastructure • The UK Railways Minister has challenged the rail industry to look at the way in which diesel only trains can be removed from operation by 2040 as part of a wide challenge to reduce carbon emissions and improve air quality across the rail sector. • In response to the Minister’s challenge, a Task Force has been set up with Malcolm Brown (Chief Executive, Angel Trains) as Chair. It will report back to the Minister in Autumn 2018. • There is no one size fits all when the UK Government looks at alternatives to diesel. Considerations such as affordability and Value for Money will be important considerations.

  • Options of Natural Gas Pipeline Reassignment for Hydrogen: Cost Assessment for a Germany Case Study
    Options of Natural Gas Pipeline Reassignment for Hydrogen: Cost Assessment for a Germany Case Study Simonas CERNIAUSKAS,1(1) Antonio Jose CHAVEZ JUNCO,(1) Thomas GRUBE,(1) Martin ROBINIUS(1) and Detlef STOLTEN(1,2) (1) Institute of Techno-Economic Systems Analysis (IEK-3), Forschungszentrum Jülich GmbH, Wilhelm-Johnen-Str., D-52428, Germany (2) Chair for Fuel Cells, RWTH Aachen University, c/o Institute of Techno-Economic Systems Analysis (IEK-3), Forschungszentrum Jülich GmbH, Wilhelm-Johnen-Str., D- 52428, Germany Abstract The uncertain role of the natural gas infrastructure in the decarbonized energy system and the limitations of hydrogen blending raise the question of whether natural gas pipelines can be economically utilized for the transport of hydrogen. To investigate this question, this study derives cost functions for the selected pipeline reassignment methods. By applying geospatial hydrogen supply chain modeling, the technical and economic potential of natural gas pipeline reassignment during a hydrogen market introduction is assessed. The results of this study show a technically viable potential of more than 80% of the analyzed representative German pipeline network. By comparing the derived pipeline cost functions it could be derived that pipeline reassignment can reduce the hydrogen transmission costs by more than 60%. Finally, a countrywide analysis of pipeline availability constraints for the year 2030 shows a cost reduction of the transmission system by 30% in comparison to a newly built hydrogen pipeline system.

  • Hydrogen Enriched Compressed Natural Gas (Hcng) – a Futuristic Fuel for Internal Combustion Engines
    HYDROGEN ENRICHED COMPRESSED NATURAL GAS (HCNG) – A FUTURISTIC FUEL FOR INTERNAL COMBUSTION ENGINES by Kasianantham NANTHAGOPAL a*, Rayapati SUBBARAO b, Thangavelu ELANGO a, Ponnusamy BASKAR a and Kandasamy ANNAMALAI c a Automotive Research Centre, SMBS,VIT University, Vellore-14, Tamilnadu, India, e-mail: [email protected] b Department of Mechanical Engineering , Indian Institute of Technology Madras, Chennai-25, India. c Department of Automobile Engineering , MIT Campus, Anna University, Chennai-25, India Air pollution is fast becoming a serious global problem with increasing population and its subsequent demands. This has resulted in increased usage of hydrogen as fuel for internal combustion engines. Hydrogen resources are vast and it is considered as one of the most promising fuel for automotive sector. As the required hydrogen infrastructure and refueling stations are not meeting the demand, widespread introduction of hydrogen vehicles is not possible in the near future. One of the solutions for this hurdle is to blend hydrogen with methane. Such types of blends take benefit of the unique combustion properties of hydrogen and at the same time reduce the demand for pure hydrogen. Enriching natural gas with hydrogen could be a potential alternative to common hydrocarbon fuels for internal combustion engine applications. Many researchers are working on this for the last few years and work is now focused on how to use this kind of fuel to its maximum extent. This technical note is an assessment of HCNG usage in case of internal combustion engines. Several examples and their salient features have been discussed. Finally, overall effects of hydrogen addition on an engine fueled with HCNG under various conditions are illustrated.

  • Developing Hydrogen Fueling Infrastructure for Fuel Cell Vehicles: a Status Update
    www.theicct.org BRIEFING OCTOBER 2017 Developing hydrogen fueling infrastructure for fuel cell vehicles: A status update This briefing provides a synthesis of information regarding the global development of hydrogen fueling infrastructure to power fuel cell vehicles. The compilation includes research on hydrogen infrastructure deployment, fuel pathways, and planning based on developments in the prominent fuel cell vehicle growth markets around the world. INTRODUCTION Governments around the world continue to seek the right mix of future vehicle technologies that will enable expanded personal mobility and freight transport with near-zero emissions. This move toward zero emissions is motivated by the simultaneous drivers of improving local air quality, protecting against increased climate change impacts, and shifting to local renewable fuel sources. Electricity-powered plug-in vehicles and hydrogen-powered fuel cell electric vehicles offer great potential to displace the inherently high emissions associated with the combustion of petroleum- based gasoline and diesel fuels. Hydrogen fuel cell electric vehicles offer a unique combination of features as a zero-emission alternative to conventional vehicles. Fuel cell powertrains, converting hydrogen to electric power to propel the vehicle, tend to be about twice as efficient as those on conventional vehicles. Hydrogen fuel cell vehicles are typically capable of long trips (i.e., over 500 kilometers or 300 miles) and a short refueling time that is comparable to conventional vehicles. Furthermore, fuel cell vehicles are expected to be less expensive than conventional vehicles in the long run. The Prepared by: Aaron Isenstadt and Nic Lutsey. BEIJING | BERLIN | BRUSSELS | SAN FRANCISCO | WASHINGTON ICCT BRIEFING diversity of fuel pathways to produce hydrogen allows for the use of lower-carbon, renewable, and nonimported sources.
