It is if it is made with renewable energy. Stop pretending that it is not.

3% green means 97% filthy.

You seem to be confused about H2 and renewable energy.

Here's a video that may help:

And here's the "Father of EV's" in China. Do you imagine that you know as much as Wan Gang about electric vehicles and hydrogen?

I'm not confused at all.

The 3% figure comes from the very article you posted. The numbers on NZ's grid requirements if we ditched diesel and petrol come from government figures.

H2 is simply a store of potential energy, and requires energy to create. its a lossy process so inherently less efficient than burning pre-potentialised octane, but still heaps better than batteries.

You don't seem to be able to disentangle H2 and 'green' in your mind. You will forever be foolish if you can't separate the two and understand the true role of H2.

Doubling the electrickery requirements of a nation's energy supply is an immense task. replacing with 'renewables' that are anything other than geothermal, nuclear or hydro means that the supply becomes increasingly unstable, subject to massive undersupply in the case of storms (cf. south australia's repeated blackouts last year after they'd taken their coal powered backup offline).

So you either have to build conventional power sources that match the renewables in output then not use them efficiently, which is a net loss to pollution, or you have to build huge amounts of lossy and/or dirty storage. (cf. lakes of death in China associated with battery tech)

Do you think you can crack enough water to provide H2 to power electricity gen to match a doubled grid when the solar and wind goes down? Because that means you now need to have 2.5 - 3x the peak supply that we currently have.], plus H2 powered generating infrastructure that sits idle most of the time. Might be more efficient to push water uphill, at least that's not an explosion risk. And we are talking about immense H2 storage to buffer the grid.

H2 is great. It isn't green, its neutral at best.

Rubbish, piled on rubbish. I'm pretty sure I understand the "true" role of H2 after studying the industry for the last 5 years.

All of this and more has been studied by actual professionals, which it seems you are completely unfamiliar with

International Energy Agency: The Future of Hydrogen -Seizing today’s opportunities 203 pg study, 6/2019

At the request of the government of Japan under its G20 presidency, the International Energy Agency (IEA) has produced this landmark report to analyse the current state of play for hydrogen and to offer guidance on its future development.

The report finds that clean hydrogen is currently enjoying unprecedented political and business momentum, with the number of policies and projects around the world expanding rapidly. It concludes that now is the time to scale up technologies and bring down costs to allow hydrogen to become widely used. The pragmatic and actionable recommendations to governments and industry that are provided will make it possible to take full advantage of this increasing momentum.

Given a choice between an anonymous poster on the internet and IEA professionals, I'm going with the pros.

Think whatever you want about H2 and Renewable energy. Won't make even a tiny tiny difference to the Leaders in this sector- China, Japan, Korea and soon Australia

You are obviously informed, yet you still tout H2 as green and clean. Which makes you a liar. At best it is neutral.

You also need to brush up on the 'logical fallacy' crib sheet. Your responses carry zero weight. You don't address the points even slightly, just make calls to authority and ad hominem.

Which makes you a liar.

It's unfortunate that you have resorted to this. But I've come to expect it from the likes of you.

You also need to brush up on the 'logical fallacy' crib sheet.

You need to brush up on today's hydrogen industry. And I don't really care what you think about it. Directly insult me again and watch what happens. Now don't you have anything better to do?

More projection, and confirmation that you put me into a box because I didn't respond to your false claims of 'green' based on 3% renewable power to crack water.

You need to brush up on today's hydrogen industry.

Avoiding the issue again. It is patently obvious that I am informed about today hydrogen industry. But for some reason you refuse to address the reality of the power input required.

So I'm going to call you out again, as a liar. What you going to do?
