    I was going to ask who was getting the bung, but I see that Toyota commented in the article ....

    IIRC, Honda have an interest in fuel cells as well?

    Thought I would have a look to see how many filling stations there were in the UK...

    https://www.netinform.net/H2/H2Stations/H2Stations.aspx

    Looks like there are 23 of which 8 are marked as "out of operation". A further 5 are "planned".

    Only London has any significant "coverage" but even there 2 out of the 6 are out of operation.

    If hydrogen is used as a combustion fuel in a vehicle, are there stil NOX issues?

    Steamy,

    Found a reference for you:

    http://www.krishisanskriti.org/vol_image/02Jul2015120719Paper%201.pdf

    See section 4.3

    The short answer would appear to be 'yes'. However, tuning of ICE engines for hydrogen will probably have much more development.

    So time to renew interest in lean burn engines (which diesels are I think).

    The problem with fine tuning combustion to minmise (even eliminate) particulates, NOx etc, is that it relies on top condition and maintenance-to-spec of physical and digital equipment. As soon as either of those drift off, as they do, the emissions revert to form (same applies to dreams of carbon-capture at power stations). As a solution for combustion, it's evidently un-robust, as our everyday experience shows.

    Question, though - does hydrogen fuel cell amount to 'combustion' in this sense?

    I don't think so. Fuel cells get warm but they don't get hot in the way an ICE does.

    The exhaust water from the Shuttle's fuel cells was processed to remove any excess hydrogen dissolved in it after which it was fit to drink. However, that might not be representative of car fuel cells as the Shuttle's took hydrogen and oxygen as input whereas car ones take hydrogen and air.

    Hydrogen vehicles generally use a fuel cell to convert hydrogen directly to electricity therefore no ozone produced by sparks so no NOX
