    A plan to consider turning all UK gas for heating and cooking to Hydrogen

    "Heating and cooling U.K. homes accounts for about half of all energy consumption and a third of carbon emissions. And about 80 percent of homes use natural gas (methane) for heating and cooking3. One of the options being explored is to replace methane with hydrogen, as hydrogen releases no carbon dioxide when converted to heat. A U.K.-wide conversion to hydrogen gas could reduce heat emissions by at least 73 percent as well as supporting decarbonisation of transport and localized electrical generation4."

    544 pages of study suggesting they are serious.

    "3.0Large scale hydrogen production and storage technologies" in the PDF covers the current technology very well. I think our CSIRO has made the Ammonia Cracking even cheaper and safer than the report

    Perth Hydrogen Fuel Cell Bus Trial | Eltis

    I note they carefully say "double decker"

    I spoke to the MD of the then BOC about this.
    He told me that the trial was the biggest challenge he had ever faced as MD of BOC and that the provision of Hydrogen pure enough for the limited fleet was the greatest challenge.
    Apparently most hydrogen is 97% hydrogen and appropriate for industrial purposes, however the buses required 100% pure hydrogen.
    He said that the provision of 100% hydrogen on a large scale was very difficult and expensive.(impossible?)
    I don't know whether subsequent developments have changed this scenario.

    One of these with 99% purity and powered by a few solar panels could work here. The poms might not have enough sun shine Wind might work for them



    IF below cost a lot less than the estimated "$10,000 per unit," I would happily have it on to my D3 for a 20-30% fuel savings " injecting hydrogen into the air-fuel mixture of a diesel engine can dramatically improve fuel mileage and lower its emissions. HyTech promises a 20 to 30 percent reduction in fuel consumption, 85 percent less particulate matter, and a reduction in nitrogen oxides of 50 to 90 percent. "

    Could the Future of Ultra Low Emissions Be...Diesel?

    i have always thought hydrogen could be the go.

    BMW have been working on them for quite a while.

    As would happen with any fuel,think LPG.

    LPG is compressed. is the hydrogen compressed?
