No Andy I am afraid that statement from the National Grid simply won't do, at all.
The issue is the phrase "CCUS" which stands for "Carbon Capture Usage and Storage" by which the UK government mean in detail the content of this wholly unacceptable and unscientific PDF
Let's leave aside the "U" for usage or utilisation for now and focus on the unscientific claim of industrial-scale storage of carbon dioxide gas in disused North Sea oil and gas fields. This was previously promoted and referred to as "CCS" - Carbon, Capture and Storage - but for reasons I will explain should be more scientifically and accurately known as "CCS-LEAK".
There can be no guarantee that any carbon dioxide gas allegedly "stored" would never leak.
CCS-LEAK businesses could boost their profits by surreptitiously leaking carbon dioxide.
An accidental large leak of carbon dioxide would form a suffocating heavier-than-air cloud which would settle over the sea and perhaps drift over land - killing sea mammals like dolphins and whales and fishermen and over land could kill animals and people. A very large cloud release by a catostrophic failure caused by say an earthquake could release vast clouds of carbon dioxide which could kill a very large number of people - possibly millions. This is the most dangerous proposal you have ever read about - it is much more dangerous - a clear and present danger - than even global warming.
If global warming is the problem and CCS-LEAK is offered up as an alleged "solution" - then the so-called "solution" is much worse than the problem. In short, CCS-LEAK is what you get when bureaucracy and capitalism get their heads together to boost profits, sacrificing everything else - the environment, people and even the sanity of the UK's politics. CCS-LEAK is nuts.
There is not one shred of scientific credibility in the claims for CCS-LEAK - which was offered up as a smoke and mirrors deception to disguise fossil-fuel business as usual.
Now the "U" for usage, minus any claims for large scale "storage" but only if the carbon dioxide is sourced from biogas, biomass or any bio-fuel, could indeed be used for net zero - to make synthetic hydrocarbon fuels (such as methane, for the gas grid) by chemical combination with hydrogen gas sourced from electrolysis of water using solar, wind or tidal power.
However despite the merits of "U" without "S", those merits are trashed by inclusion with "S" in CCUS. So whilst CCU could be OK, CCUS is ruined as a concept by the inclusion of "S" for storage.
So why did the supporters of "U" not advocate it for separately, where it would get clear scientific support? Good question and the suspicion is that the supporters of CCS-LEAK - the fossil fuel industry lobby - have stuck a "U" in there to promote CCUS to try to greenwash their claims for CCS-LEAK, but no-one should be fooled. It is not really the "U" to use carbon dioxide the fossil fuel lobby are really all about, it is the "S" for storage they are really for and the "U" is just there as a kind of fig leaf to greenwash the fossil fuel CCS-LEAK scam.
Now, if the National Grid or anyone else wants to know how to design a 100% renewable energy, net zero electricity grid, they only have to read my 100% Renewable Energy blog - CCS-LEAK scams not included!
