The British Rail Class 600 Breeze was a proposed class of hydrogen fuel cell-powered multiple units that was to have been converted from existing BREL Class 321 electric multiple units. The project commenced in 2018, but was cancelled in 2022 before any conversions took place.
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...
Hydrogen fuel cell powered Mercedes-Benz Citaro at Stratford in 2004. In January 2004, three hydrogen fuel cell powered buses were introduced on route 25 on a two-year trial. [20] [21] These were transferred to route RV1 in September 2004, [22] and were tested in commercial service on the route at peak times only. They were withdrawn in January ...
The Hydrogen Expedition is currently working to create a hydrogen fuel cell-powered ship and using it to circumnavigate the globe, as a way to demonstrate the capability of hydrogen fuel cells. [134] In August 2021 the UK Government claimed it was the first to have a Hydrogen Strategy and produced a document. [135]
Hydrogen is a common and easy to find element, given that each molecule of water has two atoms of hydrogen for every oxygen atom present. [10] Hydrogen can be separated from water via several means, including steam reforming (normally involving the use of fossil fuels) and electrolysis (which requires large amounts of electricity and is less commonly used).
Japan got its first commercial hydrogen fueling station in 2014. [107] By March 2016, Japan had 80 hydrogen fueling stations, and the Japanese government aims to double this number to 160 by 2020. [108] In May 2017, there were 91 hydrogen fueling stations in Japan. [109] Germany had 18 public hydrogen fueling stations in July 2015.
Hydrogen can be deployed as an energy source in fuel cells to produce electricity, or via combustion to generate heat. [169] When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapour. [169] Combustion of hydrogen can lead to the thermal formation of harmful nitrogen oxides. [169]
Given a heat value of a fuel, it would be trivial to convert from fuel units (such as litres of gasoline) to energy units (such as MJ) and conversely. But there are two problems with comparisons made using energy units: There are two different heat values for any hydrogen-containing fuel which can differ by several percent (see below).
