Excellent video mate, well done. For clarity, I'm ex offshore oil and gas (one of the engineers that installed Pohokura) and currently developing renewable energy projects in New Zealand. I do have a bit of knowledge on what is happening in the NZ energy industry and I think you did really well, as in very accurate.
Really good well researched video mate, I've since gone back and watched your Electricity System and Tiwai videos, and I'm now subscribed (and I'm looking forward to your Tiwai update explainer).
Great video! Oji Kinleith make pulp for export and packaging papers that are used by converters in NZ and Aussie to make cardboard boxes and paper bags. The majority of gas is used in boilers to generate steam for process heat via a cogen turbine. The rest of the gas is used in lime kilns.
Well researched, accurate, and balanced. Great job! The great hope for hydrogen production is cheap electrolysis of water powered by excess solar and/or wind. (Might take a few years to get there though.) I was disappointed that the govt decided in favour of off-shore sea-bed mining off the South Taranaki coast, instead of the wind farms that wanted to use the same bit of sea. Making the backward-looking choice as usual.
Another excellent video. It's criminal how few subscribers you have, considering the effort you pour into these videos. I've noticed that we kiwis absolutely love and devour online content just as much as any other nation but for some reason we're deathly scared of pressing that free 'Subscribe' button. I wish you the best of success. I enjoy your videos and have subscribed.
75% as usually but man your videos are great source of information ❤ can you dive into the monopoly of companies here? This is alarming! Is there no anti-monopoly laws here?
Another of your excellent interesting videos ! Good job only 50% faster than my brain can retain ! When you mentioned "gas lost in transmission " I thought it was to do with post election events/outcomes...... Al very interesting ! Thankyou 😉🙃😎
Nice video. I have a large house with plenty of gas appliances (flued heaters / gas hobs etc). One of the issues with moving to electricity (I would love an induction hob) is that the electric connection to the street isn't sized to run this sized house just on electricity. This would be a quite common issue I would think and I would ideally want another phase or two added. Increasing the lead in now would come at quite some cost. Although not great for the economy, it would be good for the current residential gas consumers if the industrial transitioned to electricity. The gas reserves would last a lot longer if some of the main gas users stopped (esp methanol production) and left the reserves for the existing residential users, limiting new residential connections.
You make good points. My house had gas cooking, hot water and I had a gas space heater but I got my gas disconnected in 2007. Heating is now mostly by heat pumps, I have solar hot water panels to help the electric hot water and I got a small stove that plugs in to a regular outlet (not a solution for everyone). So yes it is do-able without increasing the capacity of the electricity supply cables to your house but some compromises have to made.
@@johnhornblow4347 63A at 220V (not 240 due to voltage drop, also local conditions) = 13.8KW capacity. In the last 6 months my peak load has been 10125W (I have a phototransistor on the pulse light of my meter and have detailed records), but, this is with gas heating and probably not running everything at once. I don't have the capacity to add 4-6 KW using multiple burners and heat the house. Ah, I also have a gas storage heater so that's more load that would need to be added (2-3KW) if fully converting. Induction heaters are more efficient, as in more of their energy is converted to heat, don't pollute locally, give better air quality and are more responsive but, I don't have the spare capacity in my house to add this. If I had a second phase I could split and move things around but the leadin is single phase and quite inaccessible now. Also - would need new power cables run to hob location as the current (heh) ones only sized for the ignitors (2.5mm²). Given the distance from the power board, and the insulation, I would probably need a 16mm² cable run to be added. A similar induction hob (fisher and paykel CI926DTB4) to what I currently have in gas can pull 11.1KW according to the specs, up to 48A on a single phase. Obviously you normally wouldn't be pulling all of that at a time, but, this sort of appliance needs more than a bit of thought put into installing it.
Is it possible to use a 3 phase domestic battery/ batteries to power an induction hub with? Have the 'trickle' recharge of the battery overnight on a night rate or from roof solar panels. Even if you upgrade the supply power cable to the house, the grid power is always likely to increase. Concrete containment for the battery/ ies may be a consideration.
Awesome videos. So much useful information, and it's really cool that you've travelled to many of the locations for shooting. Kudos! I do think on average viewers (and your channels growth) would benefit from having you talk a bit slower though (those who like to listen faster can increase the speed).
I would say an LNG import setup is very likely for NZ. Australia is probably building at least 2 LNG import terminals- one south of Sydney and offshore from Melbourne. At Huntly the coal storage areas can be seen on google earth, they might need to build a few days supply of gas storage in the farm land away from the town. Gas is probably preferable to ripping into the countryside for wind farms like are taking place in Northern Queensland. (see Stephen Nowakowski)
NZ has far greater offshore wind potential than it can use. Unless you have massive dispatchable RE like proper hydro, synthesising something you can burn in power stations to fix intermittency is a solid plan. That same plan, for countries with giant VRE and hungry neighbours, promises lucrative exports too. It's unfortunately a 'windfall' harvest though, like organic farming, so investors don't like it.
In Scotland we have pumped storage for filling peaks in the demand for electricity. Even coal and gas can't 'spin up' fast enough to cope with 4 million kettles going on after TV soaps finish or a big football, soccer' game ends.
Ok watched. Good. Methane is economically/industrially upstream of an awful lot of other stuff, like your examples. In Qatar they make motor fuels with it by "Gas-to-Liquids", and elsewhere it's feedstock for polymers. Decarbonisation itself is barking mad, but we have to stop adding fossil carbon to the modern atmosphere and also 'fix' the extra we've added. The obvious answer to me for countries with giant VRE (like UK, NZ) has always been e-NG. We can 'slip it in' without upsetting anyone like most other NetZero policies have.
nice. However, NZ being 70-80% hydro means we can just smash into installing wind + solar as much as possible, without having to think about energy storage too much.
Except that we don't have much hydro storage. Pukaki is our largest energy storage lake with 800Twh. Unfortunately, its pretty much those with Hydro asset that can afford to get into the big leagues with wind and solar. The risk is too high for anyone else to contemplate.
NZ is not 70 - 80% hydro. Hydro accounts for only about 40% total energy. If you are speaking about electricity supply only - I think it fairer that you should say so.
@@flit-the-history damn, I thought it was much higher than that. Worth remembering that we're not trying to replace supply with renewables, we're trying to replace demand, which is a much smaller number. LCOE of wind or solar + battery is still the cheapest electricity to install right now. There really is no excuse for nz not to go fully renewable, even with increasing demand. Economies larger than ours are doing it, and economies smaller than ours are doing it. We just have to start doing it.
the sped up speaking is excellent I can keep up easily, be careful how far you will step into the Green/ Greenies Zone because of retraction is nearly impossible if you go too far in. Think about this if any of the things to replace fossil fuels worked beautifully efficiently cost-effectively and could actually be done . The fossil fuel companies would love to transition over they don't care what they sell as long as they sell . By the way my new cooktop is magnificent it uses more electricity than my welding machine by a lot
Yes, so long as we keep putting our eggs in the 'weather dependent sources of electricity' basket, we're going to need systems to cover the shortfall. We don't like comprehensive forward thinking in this country, so where a massive system of batteries would be needed (at great cost and complexity) it will probably fall to gas peaking plants to actually keep the lights on. A real solution to replace gas and have the overhead to make up for industrial electrification is to build more sustainable clean energy sources. Wind and Solar kind of fit the bill, if they didn't last less than 30 years and also need enormous storage systems, be they heat batteries, electrochemical batteries, or pumped water storage. Hydroelectricity is always an option, there are plenty of places in New Zealand projected to get rainier as climate change deepens. However it's highly unpopular. Which really leaves two proven options for New Zealand going forward: A lot more geothermal, or a nuclear power plant. I would honestly prefer we build a nuclear power plant. Something like 2-5 CANDU 6, 9 or ACR reactors to permanently shutter every gas and coal plant in New Zealand, while leaving overhead for having a reactor out of service for maintenance. CANDUs in particular owing to their relative simplicity, and the ability to refuel them while they're operating. They can also operate on unenriched uranium, spent fuel from LWRs and BWRs, reprocessed fuel, mixed-oxide fuel from decommissioning nuclear weapons (which I feel would mesh quite nicely with New Zealand's anti-nuclear weapons stance), and may even be able to breed their own fuel if they were configured as fast-neutron reactors, which is what India's been trying to do with their CANDU-style reactors.
Yes well done, you quoted a number. But the overwhelming majority of that generation is exactly what I said is the stuff we need to be focusing on, geothermal and hydroelectricity. Dispatchable, sustainable sources of electricity. As of 2130 4/11/24 the mix is: 3267 MW Hydro 946 MW Geo 747(heh) MW Wind 90 MW Coal 76 MW Gas Building nuclear, hydro, or geothermal means we can shut down the fossil fuels, and when the wind farms come to the end of life we don't need to replace them, and also won't need to build pumped storage (though it's nice to have) and we similarly won't need to build any other forms of batteries, centralised or distributed, nor will we need a massive grid reconstruction effort. Y'know, saving the country money while at the same time making all our electricity low-carbon, which is the goal?
@@TheSonic10160 Haha not a solution! No mention of solar? That is the solution, not nuclear (far too expensive and slow, too large for NZ, radioactive, needs lots of cooling water), not hydro (no suitable rivers left), not geothermal (far too small to be significant, no suitable sites left). Surely wind can continue to complement solar and batteries have been shown to be sufficient storage because wind and solar are intermittent but reliable (the sun comes up every day). The whole grid needs redesigning to allow for distributed generation and managed consumption. We already do this with Tiwai point smelter, we could do this more with vehicle charging. All this is much cheaper, quicker, easier to implement in a staged manner.
Everyone should check the £4bn out of the public purse every year for UK's "Nuclear Dustbin Authority". Widely regarded to be necessary to pay for 100,000 years, it'll go up with every new reactor we fuel, and we can never stop paying it for mistakes we made last century. I think the objective is for our descendants not to say "cunts" every time they mention us?
Great video. I hate everything you talked about. Overseas everyone thinks our country is so clean and green, yet for our population size we do an incredibly detrimental amount of fossil fuel extraction and consumption. Things need to change but our government wants to do MORE! Overwhelmingly depressing how bad of a decision that is.
Methane is emitted when there is no oxygen when it decays and CO2 when there is I thought. How are they going to get all the organic matter under water?
You are totally not from Taranaki Stafford 😂 it’s Stratford i live in kapuni and and a engineer all I say is drill baby drill we just need a new government that has no politicians and everything will be way better for the whole country
Drilling costs money and there's no guarantee of a strike. You don't have to drill for wind or sunshine. As at 1.30pm 4th Nov. 2024, 98% of NZ's electricity is coming from renewables. Source: Transpower.
Using gas infrastructure for hydrogen, what a joke. Hydrogen leaks through metal itself, and even more-so at the joins. It is a greenhouse gas because it uses up radicals that would otherwise be converting methane to CO2. Thanks for the video, didn't need .75 speed like a lot of commenters, keep it going!
To compliment the phrase "biogenic carbon" I made up the words "geogenic" and "aerogenic". Biogenic = carbon source is from living matter and is carbon neutral. Geogenic = carbon source is from underground and is carbon positive. It's cheap energy (for now at least) but it's warming the planet. We've got to stop using it at some point. Aerogenic = carbon source is from the air. Very expensive (for now at least) but carbon neutral if it is burnt or carbon negative if put underground. We'll need to eventually do this, probably once solar is so cheap it's basically free at certain times of the year.
Finally, a video I don't have to play at 1.5x

Renewable Natural gas (AKA biomethane) can replace natural gas in the heating sector.
