Re: Alstom H2 Trains in UK - not all goo... Alstom signed a 10 year deal with Canadian company Hydrogenics to supply FCs. The German demo train Corada iLint wasreported to use 8x35kW units (they show bigger units in their catalogue so not sure why so many small units, maybe more controllable). Siemens have also signed up with Ballard to develop a hydrogen FC train, based on a 200 kW unit with German Govt funding targetting 2021 deployment. H2[link]

Re: Alstom H2 Trains in UK - not all goo... Joatmon"In order to separate the atoms of the hydrogen and oxygen and actually generate hydrogen fuel, fossil fuels are needed. "Not strictly true. H2 can be produced by electrolysis of water using electricity from renewable sources, solar wind etc. or by conversion of biomass, (wood, straw etc).That said most hydrogen is currently produced from fossil fuels. But then most electricity to recharge battery electric vehicles is produced from fossil fuels. Power generation emits a lots of NOx, CO2, SOx, particulates etc. Most H2 production also emits similar emissions depending on the process used, so Battery Vehicles have many of the same benefits and drawbacks as FC Vehicles. FC NOx emission from membrane FCs used in vehicles is (I believe) much lower than the cleanest ICE. CO2 can be sequestered (pumped into a suitable geological structure) but that isn't cheap or efficient. The only really carbon free routes to H2 or Battery EVs are renewables, or nuclear.

Re: Alstom H2 Trains in UK - not all good? From the internet:"Disadvantages of Hydrogen Fuel Cells. In order to separate the atoms of the hydrogen and oxygen and actually generate hydrogen fuel, fossil fuels are needed. This completely defeats the purpose of an alternative energy source. If we ran out of fossil fuels we would no longer be able to produce hydrogen energy."List of Disadvantages of Hydrogen Fuel CellsNitrogen Dioxide Emission. Critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions. ...Storage Issues. ...High Cost. ...Highly Flammable. ...Climate Change Aggravation.

Telegraph- Alstom H2 Trains in UK Hydrogen train initiative (below), probably a lot better route to eliminating diesel loco's than electrifying all routes. Hydrogen distribution relatively easy, you know where the trains are going so can cover with limited number of refuelling stations. Fairly easy to package bulky and heavy hydrogen storage cylinders or cryo storage on a train. Cryo would be a good fit for trains due to high volume needed, but liquid H2 supply in UK is I believe still very limited so I guess high pressure gas would have to be used. Unclear whether H2 is a better option than battery for trains, it would seem easy to provide rapid recharge points along the route, either whilst stationary or for a short electrified section. I imagine Alstom will be getting Govt or EU funding support.I am less convinced that hydrogen will be competitive for road transport against battery vehicles, the size and weight of the storage and overall cycle efficiency from fuel to propulsion (including either road hauling from bulk supply or compression of on-site electrolysis, but that technical race is not yet decided. H2French train manufacturer Alstom is set to become the first company to bring hydrogen trains to the UK with its plans to convert an existing fleet.The company said the move was the “first substantive industry response” to calls by the Government for the removal of all diesel rolling stock by 2040.Alstom will convert a fleet of Class 321 electric trains by fitting hydrogen tanks and fuel cells to power them. The fuel cell on the trains will produce electricity through a combination of hydrogen and oxygen to create water. The electrical energy is then intermediately stored in batteries and the train is powered by an electrical traction drive. The only exhaust is steam and condensed water.Alstom will carry out the work at its site in Widnes, Cheshire and will also partner on the project Eversholt Rail.The move will be welcomed by the Government after Rail Minister Jo Johnson called in February for the removal of all diesel rolling stock by 2040.[link]

Gas battles and demand for gas. From the beeb."Off the coast of Western Australia, a battle between mega giants is unfolding. The combatants involve the world's biggest semi-submersible platform, the longest subsea pipeline in the southern hemisphere, and the largest floating facility ever built.They're all there for the same reason: natural gas - and they're hoping to start drawing it up this month. As several countries begin to move away from coal as an energy resource, this alternative fossil fuel, which produces 50% less carbon dioxide for every unit of energy generated, is increasingly in demand in our energy hungry world. Consumption is forecast to rise to 177 trillion cubic feet (tcf) or 5,012 billion cubic metres by 2040, up from 124tcf in 2015, says the US Energy Information Administration.That's why Shell's gigantic Prelude platform - which is 488m (1,600ft) long and displaces roughly as much water as six aircraft carriers - is competing with Japanese firm Inpex for access to gas in the Browse Basin.Although they are working on separate gas fields, those fields are connected. Shell and Inpex are essentially vying for the same resource."The way I describe it - I have a slide I present to clients and I have a picture of two people drinking out of the same milkshake," says Saul Kavonic, an analyst at energy consultancy Wood Mackenzie.Prelude is a true behemoth. The largest vessel the world has ever seen, it has been designed not only to collect gas from sub-sea well heads, but also liquefy it on board at temperatures of -162C. As a liquid, the gas takes up significantly less space, making it easier to transport around the world on ships. This liquefaction would usually be done after piping the gas onshore, but Prelude can do the job herself - something never achieved on such a scale before.Some serious technology is involved in making this happen. Prelude has high-capacity pumps that can draw 50 million litres of water from the sea every hour to help cool down the natural gas. Once liquefied, it is then stored in massive storage tanks with a volume equivalent to 175 Olympic swimming pools.And this all has to keep going even through the worst imaginable weather. Prelude's hefty mooring chains are designed to survive Category 5 cyclones.While Inpex has opted for sending its gas onshore for liquefaction, it also has a huge offshore semi-submersible platform to extract water and impurities from the gas first. And nearby, there is a floating storage and off-loading facility called Venturer. However, both projects have been beset by delays and spiralling costs, which may be why neither company was prepared to talk to the BBC for this feature. The pressure to start drawing gas first is obviously intense. The race for Browse Basin gas has even ignited competition on an international scale. Australia may overtake Qatar to become the world's top exporter of liquefied natural gas (LNG) once Ichthys and Prelude production is in full swing. But will any future vessel match or even exceed the scale of Prelude? Mr Kavonic says the fossil fuel industry isn't likely to try to build one any time soon."We need new projects to meet demand [for gas] in the early 2020s," he explains. "We needed projects to be sanctioned last year and that didn't happen, we only saw one."That single project will be built by Italy's oil and gas giant Eni. A floating facility off the coast of Mozambique, it will have a slightly smaller capacity than Prelude - 3.4 million tonnes of LNG per year versus Prelude's 3.6 million. The capacity of Ichthys will be much bigger, at 8.9 million tonnes."There's so far no [other] similar projects under the radar," says Jean-Baptiste Dubreuil from the International Energy Agency. Without more projects for gas production, industry watchers worry that, in about five years' time, demand for natural gas could outstrip supply. There is the "spectre of an LN
