Some Bad Vaccine News From Italy

This reassuring article in The Times with a reassuring title of Single Covid Vaccine Reduces Risk Of Going To Hospital By 90%.

But it does contain one piece of bad news.

An Italian study has suggested that the Pfizer vaccine is less effective in overweight people.

H2 Green Steel Plans 800 MW Hydrogen Plant In Sweden

The title of this post, is the same as that of this article on montel.

The title says it all.

In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.

Ryze Hydrogen are building the Herne Bay electrolyser.

  • It will consume 23 MW of solar and wind power.
  • It will produce ten tonnes of hydrogen per day.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

This would mean that H2 Green Steel’s electrolyser could be producing around one hundred and forty thousand tonnes of hydrogen per year or 380 tonnes per day.

What About Scunthorpe?

I very much believe that Scunthorpe in Lincolnshire, would be the ideal place for hydrogen steelmaking in the UK as I outlined in Green Hydrogen To Power First Zero Carbon Steel Plant.

So could 800 MW of electricity be available to produce the hydrogen in the area.

Currently, the world’s largest offshore wind farm is Hornsea One with a capacity of 1218 MW, which feeds into the National Grid at Killingholme.

This Google Map shows the distance between Scunthorpe and Killingholme.

Note.

  1. Scunthorpe is in the South-West corner of the map.
  2. Killingholme is in the North-East corner of the map.

The distance is about twenty miles.

When fully developed, the Hornsea Wind Farm is planned to have a capacity of 6 GW or 6000 MW, so there should be enough renewable energy.

Could The Hydrogen Be Created Offshore?

In ITM Power and Ørsted: Wind Turbine Electrolyser Integration, I wrote about combining wind turbines and electrolysers to create an offshore wind turbine, that generates hydrogen, rather than electricity.

This approach may be ideal for the later phases of the Hornsea Wind Farm.

  • Redundant gas pipes can be used to bring the hydrogen ashore.
  • Worked-out offshore gas fields can be used to store hydrogen.
  • Worked-out gas fields in the area, are already being used to store natural gas from Norway.
  • The hydrogen can be fed directly into the HumberZero hydrogen network.

But the main reason, is that some serious commentators feel it is more affordable approach in terms of capital and maintenance costs.

It is also easy to convert hydrogen back to zero-carbon electricity, if you have a handy gas-fired power station. There could be as many of three of these at Keadby.

Conclusion

It’s all coming together on Humberside.

Anything the Swedes can do, we can do better!
