Hydrogen Fuel Supplies? Options

[Blake]

As part of my overall commitment to reducing my carbon footprint and moving evermore toward living sustainably, I am looking to buy a hydrogen-powered car like a Toyota Mirai.

Does anyone know any gas stations in West Berkshire that currently supply hydrogen to the consumer?

And stop buying goods from supermarkets that use diesel lorries for deliveries, and stop using diesel trains.
And cruise liners, and container ships.
You post as if petrol vehicles breath out fresh air!
Sorry to be cynical here but people seem to want the best of both worlds.
A nice comfortable modern lifestyle but not pay the environmental price?

..and let's not forget the environmental impact every time a plane jets us off somewhere nice. We all like to go on holiday don't we?


Rather than just pretend it's nasty diesel cars clogging up your air passages lets calculate CO2 emissions from fuel consumption per flight.

A Boeing 737-400 jet is typically used for short international flights.

For a distance of 926 km the amount of fuel used is estimated to be 3.61 tonnes, including taxiing, take-off, cruising and landing.

Using a seating capacity of 164 and an average seat occupancy (or 'load factor') of 65%, this gives a fuel use of 36.6g per passenger km.

CO2 emissions from aviation fuel are 3.15 grams per gram of fuel, which gives CO2 emissions from a Boeing 737-400 of 115 g per passenger km.

At a cruising speed of 780 km per hour, this is equivalent to 90 kg CO2 per hour.

The corresponding figures for a Boeing 747-400 (used for long distance international flights) are:
Distance: 5556 km
Fuel used: 59.6 tonnes
Seats: 416
Seat occupancy: 80%
Fuel use: 32.2 g per passenger km
CO2 emissions: 101 g per passenger km
Cruising speed: 910 km per hour
CO2 emissions: 92 kg CO2 per hour

So for both aircraft, the emissions are around 90 kg CO2 per hour.

These CO2 emissions are generally into the high atmosphere, and this is thought to have a greater greenhouse effect than CO2 released at sea level. The emissions are therefore adjusted by multiplication by a factor of 2.00 (see 'Radiative forcing' below) to give 180 kg CO2 equivalent per hour.

Further allowance is needed for fossil fuel energy used in :
• extraction and transport of crude oil
• inefficiencies in refineries (around 7%)
• aircraft manufacture and maintenance, and staff training
• airport construction, maintenance, heating, lighting etc.

The CO2 emissions are therefore rounded up and the Carbon Independent calculator takes a values of 250 kg i.e. ¼ tonne CO2 equivalent per hour flying.

And there are planes taking off and landing every second of the day...
