Highlights from Porritt's blog

Brilliant, authoritative writing from Jonathon, once more.

MY HIGHLIGHT QUOTES:

The rollout of CCS on power stations is about as naked an exercise in PREDATORY DELAY as can be imagined.

about a tonne of CO2 to be released for every tonne of cement produced.

the recent announcement from LafargeHolcim that it will be piloting more than 20 different CCS projects over the next few years.

Does this constitute PREDATORY DELAY? In my opinion, absolutely not.

Definitions:

‘grey hydrogen’ (using natural gas to make the hydrogen through a process called ‘steam methane reforming’), ‘blue hydrogen’ (using the same process, but capturing the CO2 emissions through CCS), and ‘green hydrogen’ (using electrolysis powered by renewable electricity).

all fossil fuel companies, and all EU countries and the UK, that now lump both Blue Hydrogen and Green Hydrogen together as ‘low-carbon hydrogen’.

the extra energy required to power the carbon capture process. What’s more, it takes many tonnes of natural gas to produce a single tonne of Blue Hydrogen.

In other words, unlike with concrete, blue hydrogen represents PREDATORY DELAY at its worse!
