On Q&A last night I understood Finkel to say basically three things (summarizing part of the COAG briefing report): 1. Combining consumption of natural gas with renewables makes sense as a transitional situation since, unlike coal, gas powered turbines can be ramped up and down far more quickly. Hence gas can be used as a supplement to renewables rather than renewables supplementing fossil fuel; 2. Natural gas can be seen as an interim measure, over a 10 to 30 year timescale, while efficient production of green hydrogen is improved to replace it. Infrastructure supporting the use of natural gas - pipelines, turbines etc. can be switched easily to using green hydrogen; 3. Green hydrogen is potentially sourced from water and from hydrocarbons involving low carbon dioxide emissions some of which includes carbon dioxide capture and storage. I think this was a useful contribution to the public discussion.

Hydrogen strategies for cars or export are invariably a delay tactic by fossil fuel and conservative interests. The only useful thing to do with Hydrogen in Australia would be direct reduction of Iron ores, entirely a consumption at point of use industry which eliminates the horrible storage and transport costs of Hydrogen. The export of this 'Green Steel' would be the effective way to de-facto export energy, much the way Iceland exports Aluminum as a means to export its hydro and geothermal energy. The market is assured because the Asian importing nations that already buy Australian Iron and Coal will increasingly not want the polluting smelting processes done in their backyards.

This was surprising as it seems odd to ship hydrogen half way round the world, when it could be made in the UK. If the large sunny land areas are a significant factor in the cost, then Spain or Morocco perhaps are closer. Given that hydrogen has a very low density even when compressed of liquified, it requires large, high pressure or cryogenic transport tanks which will weigh much more than the contents.

Battery production is increasing in an unimaginable way all thanks to Tesla. It truly is inconceivable the amount of batteries that will be available in just a few short years.

Why will CCS be any different for Hydrogen production from steam reforming? Further, nobody can guarantee sequestered CO2 will remain permanently safely contained underground. Western Australia has an appallingly bad record in transitioning to renewable energy. We have an abysmal 11% renewable energy. South Australia is at well over 50%. Tasmania close to 100%.

There are also, in those depleted gas sites, ready made storage by injection for hydrogen gas storage. Couple that with CSIRO’s patented technology to quickly and easily convert hydrogen gas to ammonia (which is much easier to transport in liquid form) and back again at the receiving point (more detail, here www.csiro.au/en/Research/EF/Areas/Renewable-and-low-emission-tech/Hydrogen/Hydrogen-membrane ) and Western Australia is in a solid position to be an exporter of clean hydrogen.

Open the market place by reducing regulation and force natural gatekeepers to the energy market like grid operators to allow anyone to buy and sell energy at market prices. 3. Tax technologies with unwanted side effects at the most fair and simple point in the supply chain. Tax the extraction of carbon from the earths crust directly and let the market figure out how to use the more expensive carbons best or to use alternatives. 4. Counter international forces that try to control the domestic markets.

You are very correct. Not sure how far hydrogen will percolate down into road traffic but as a base load power role there is a place. Ideally renewable power capacity should be many times the current fossil fuel based limited level. Ten, twenty. fifty times current levels. It should be abundant and cheap. At those levels only a fraction of it would require buffering via storage technology. It does not all need to be stored - the rest could be utilized literally for making hay while the sun shines. There is a huge demand for water in Australia. Desalination plants could run on excess generated electricity, winding down overnight and when the wind stops blowing then powering up again each morning supplying towns and farms. There is nothing impossible to overcome, mostly vested interests fighting to maintain the status quo.

Australia had a TV program called, Beyond 2,000 here from 1985 - 1999. It featured expected breakthroughs that should have eventuated after 2,000. Many of these were Australian breakthroughs. Sadly, I can't recall one that happened off the top of my head. Beyond 2,000 Revisited will be a very interesting TV program. I will watch it. The original was well done. I know about Cochlear and Helicobacter Pylori which were truly Australian breakthroughs. Like much of the West, Australia is also terminally ill with political correctness. Nuclear energy is Satan and solar and wind are in their pantheon of gods. Australia has the biggest storage battery in the world powered by the sun. Here is what it really can do: chrismalan.blogspot.com/2019/10/jamestown-south-australia-grid-battery.html You won't see these real-world figures touted about. I suspect greenies may make pilgrimages to the thing to pray to it. The answer is nuclear energy. But just the word, nuclear is enough to make a greenie prolapse her uterus or twist his spermatic cord. This video was highly speculative. I'd bet against hydrogen being available cheaply. My advice to Just Have a Think is to stay in the real world and steer clear of pie in the sky.

Good observations Chris. One thing we all know is that money buys politics. Right now, the fossil fuel industry has the financial means to determine energy policy in all western "democracies", and they will not give this up easily. I personally don't think that nuclear will play a significant role in cleaner energy - even with the emerging science involving thorium, etc. One advantage of course is the possibility of small-scale reactors that could "supplement" wind and solar, help with grid balancing, and provide a relatively "steady" flow of electrons into large battery (and other) storage facilities. As pointed out by many observers, hydrogen is still "atoms", and therefore requires sophisticated and extremely costly physical infrastructure to manufacture, store and transport. Even with the most efficient extraction methods, the energy required to produce it does not yet match the cost-efficiency of solar and wind. Hornsdale seems to be showing us a viable and cost-effective combination of clean generation, storage and grid balancing. Additionally, the cost of wind and solar (the infrastructure) is declining rapidly, and the technology is getting more efficient and reliable. The point of price-parity is being lowered, and hydrogen is not keeping pace. H2 seems it will forever be more expensive than solar+wind+battery - so it will be very unlikely that H2 will become a predominant energy source.

The purpose of the "Tesla Big Battery" was not to supply volumes of power, but to help keep the grid stable in a world of variable renewable energy, and in the case of Australia, a fragile grid resulting from lack of investment over the past two decades since the conservative government sold it off to the private sector. The Hornsdale Power Reserve (as it is officially named) does this very well, and also lowers the cost of power to consumers by breaking up the cartels of fossil fuel generators that game the Australian electricity market to force up power prices and increase their profits. reneweconomy.com.au/sa-big-batteries-again-steer-state-through-interconnector-dramas-28099/ reneweconomy.com.au/hornsdale-big-battery-doubles-savings-to-consumers-and-keeps-lights-on-85139/ reneweconomy.com.au/south-australias-renewables-grid-separates-from-nem-lights-dont-go-out-14232/ reneweconomy.com.au/how-the-tesla-big-battery-kept-the-lights-on-in-south-australia-20393/ As for nuclear power, that is the worst answer. It will take years to build, it is inflexible (even worse than coal in its ability to ramp up and down to meet the needs of a modern grid), and if it is ever actually finished it will generate the most expensive power in the grid.

I live just 80km from Dongara (Pronounced Don-g-ra) And everyone I know in my region of Western Australia wants more renewable energy. My town has a large power distributing facility and also the town and region has massive salt lakes. (mostly caused by land degradation) If we got large scale solar and wind farms we could use them to not only produce more hydrogen but also convert those salt lakes into extremely high quality fertiliser and get all the necessary minerals to produce huge quantities of batteries. (The state government predicts we could produce up to 40% of the worlds batteries) The only thing stopping this from happening is the federal government who are convinced that natural gas, "clean" coal and "clean" nuclear are what we should invest in. (Most of which is foreign owned and costs the Australian tax payer billions) All that being said, the Western Australian government is fighting back; not only did the state ban nuclear technology (after the shock of British nuclear weapons tests) but also it's already made it's own plans by creating the "Future battery Industry Strategy." Plus, the state plans on investing heavily in hydrogen and the state owned power company has also put forward targets on ending reliance on "Out of state" energy sources. All that being said, the Federal Government and coal lobby are pretty annoyed at this. They believe that Western Australia producing cheep, clean energy and building new industries is unfair to Queensland coal miners and mining companies... But the state government doesn't care, if the federal government won't do it, the state will do it themselves!

Amazing how small this facility talked about here will be compared to the Asia Renewable Energy Hub planned for the Pilbara region of Western Australia.

You might want to do a video on the efficiency of using hydrogen as a battery. At first glance, it seems as if it might be 100% efficient, as every electron that goes into the water goes into a released hydrogen atom. Then, every hydrogen atom that joins with an oxygen in a fuel cell releases an electron. However, is that really the case?

@grindupBaker

All energy loss is in the form of either heat or transverse electromagnetic radiation (TER). Offhand I don't recall processes that "waste" energy by emitting unwanted TER (well I do, such as welding & others but the electrolysis/fuel cell seems unlikely for that). This means that a 100% efficient system that has a purpose other than heating (probably always being the purpose of making kinetic energy, electrical energy , potential energy, pressure or TER) generates no heat. If the system can be closed then it could be assessed that way, the amount of heating as a proportion of the total energy is its inefficiency. It has to be closed to provide thermal insulation & to convert sound & mechanical/kinetic energies to heat so it can all be measured as the final energy loss, which is heat. The pressure change would also need to be measured. My point is that if "it might be 100% efficient, as every electron that goes into the water goes into a released hydrogen atom. Then, every hydrogen atom that joins with an oxygen in a fuel cell releases an electron" is correct then no heat is made (Law of Conservation of Energy). Does electrolysis run without causing heating ? Does a fuel cell run without causing heating ? Did I forget anything ?

@@grindupBaker Yes, I know the basic laws of thermodynamics and conservation of mass and energy. However, there may be electrons that go straight through the water to the other electrode. So the only result is heat. But, if that heat is contained, does it eventually contribute to making it easier for some OTHER electron to release a hydrogen atom? That "unproductive" electron still had to travel through all the wires going out to the solar panels, so we can't trap ALL it's wasted energy in the water. And we can't "imagine a spherical cow" by pretending we can even keep all the heat that was created in the water actually IN the water. Heat is also released by fuel cells. If that is trapped inside the fuel cell, does it make the fuel cell more efficient, or less? If we choose to transfer that heat to the original water (perhaps by immersing the fuel cell into the water) does that eventually make the hydrolysis more efficient? What if we allow the water to get so hot it converts to stream? Do we use that to drive a turbine to reclaim some of that "wasted" energy? What about the water vapor from the fuel cell. As vapor, that contains energy. Do we condensed that water to replenish the water in the original tank? Where do we put the heat that was extracted from there water vapor? Do we release it or use the water tank as a means of condensing the vapor. We could just literally bubble the vapor from the fuel cells through the water to directly transfer the heat and water vapor molecules into the water in the tank. We can tell if all the energy is going into the tank because no bubbles would reach the surface. So, we could design such a system to use as few additional pumps, etcetera as possible for maximum efficiency. All the pumps and hydrogen/oxygen storage tanks could be sealed and immersed in the water tank to keep all the heat inside the system. From the outside, it would look like just a big, insulated tank of water with two terminal posts sticking out of it. Like a giant car battery. My question is: Is anyone doing that? Has anyone made these calculations? Has anyone even considered using such a closed system ONLY as a battery for intermittent alternative energy sources? Would it be more efficient than a bank of lithium ion batteries? More environmentally friendly? What about energy density? But would that matter in this situation? What about cost per amp hour stored? Would this be a nonstarter based on that alone? I have no clue. Someone could build these systems to fit into the space of a standard shipping container. Then just stack them up and connect the wires, just like giant batteries.

@@GrantSR H2 + O fuel cells have been around for quite a while, they provided the power for the Apollo spacecraft. The main problem as ever has been the high cost of the fuel cells, particularly the expensive platinum catalysts and the cost of H2 generation and storage. Most fuel cell vehicles use a Li ion battery as the main propulsion due to intermittent high current draw such as taking off from lights. The battery also allows some limited regenerative braking. The fuel cell acts like a range extender continually charging the battery to give the vehicle decent range. The problem for H2 proponents is that the batteries used in BEVs have improved substantially in recent years undercutting the need for range extension. Most Tesla's for example have better than 500 km range, the model S goes further than 600km. This together with fast charging has undermined the case for hydrogen vehicles. Hydrogen might be useful for static power, but even there it has to compete with fluid batteries such as vanadium and liquid sodium. All in all green H2 looks too troublesome as an energy storage medium and will likely only feature in niche applications such as steel making and the chemicals industry.

Problem here is hydrogen production inefficiency. You are wasting 2/3 of energy. E.g. if solar/wind farm produces 10GWh of electricity and you make hydrogen with it, you get ~4 GWh from that hydrogen from fuel cells, and you wasted 6 GWh. Does not make much sense.

Except that in many cases, the distribution capacity of that cheap, renewable, and intermittent energy to the consumer is limited. Already we are seeing many renewable power facilities that often need to throttle production because they have reached the capacity of their distribution connections. Battery storage of electricity will always quickly become uneconomic for longer durations of storage as batteries are best used for short term energy storage. Using synthetic fuels and hydrogen for medium and longer term energy storage can become a much better option. So, pairing a renewable, or a network of renewable energy facilities together with a green fuel plant will likely be an excellent way to achieve higher levels of renewable development, as their development and placement will no longer be so dependent upon the robustness of the energy grid.

If solar and wind produced hydrogen can undercut steam reforming then that’s another nail in the coffin for gas, along with peaker batteries. If rising demand for hydrogen leads to more solar and wind building then the price of the technology will fall further. This is a really intriguing proposition which completes the roadmap to replacing fossil fuels in heavy transportation, industrial processes and even perhaps aviation.

Geometry and molecular-derived tensile strength to you Sir! (I am respectful - very - of your beautifully presented trains of ideas) 1) The ‘single-stalk’ wind turbine is a structural delinquency: material need be a fraction of a cost to support the vertical blade if constructed using the geometry of the tetrahedron with the whole mount swinging to keep into the wind. 2) I do not know the statistics but am told the motors frequently burn out and need replacing. Is that true? 3) The cost of a single wind-turbine might be converted into so many spinnaker sails - many scores if not hundreds of thousands. These (rationalised) deployed in a sturdy ocean current would work from the tensile principle of the molecular bond and produce so much more work in powering a land- or ocean-platform based turbine equal to their strength. At limit of trajectory all that is necessary is to release one side of the restraint and wind in to recontribute as part of the cycle. 4) Similarly wind-interfacing turbines present so little to so much - the neglected science of geodesics could - potentially - address whole weather systems placed at sea and away from shipping lanes. Dynamic Geodesics rather than the space enclosures generally explored by R.B. Fuller. Might suggest in this connection that off-shore platforms may benefit from employment of the geometry of the syncopated cubeoctahedron known as ‘khat matrix’ - a dry fix modular assembly which can fix sea-water in position to any desired degree.

How about doing a vid about Carbon Negative Algea Bio Fuel, that permanently removes 10 pounds of CO2 for every gallon of Algea fuel!.

Also Algea is grown in Photo Bio Reactors( PBR) that are easy, cheap and quick to build, and could be rolled out country wide in 5-10 years. As I said I truly and strongly believe we need to use our ICE to sequester Carbon, as we have no other way to sequester enough CO2 in next 10 years. And no other alternative fuel can transition as fast as Algea Bio Fuel, let alone be Carbon Negative. Also the Algea can be fed Landfil runoff, industrial gasses, Waste water etc. So helping the environment and saving energy while it grows, and would create millions of local Green jobs, and keep fuel money locally for other transitional projects.

Like a nice Mueseum Australian will be johny come lately. www.secure-supply.com www.hot-rod-usa.com ps this channels is very good but unforntunatley the aussie media is so far behind and false that the people are not even aware of the size of the gap

Most Aussie media is unfortunately controlled by Murdoch. This is a better source reneweconomy.com.au/

The Germans were using hydrogen to fly around the world in the late 1930's.

I read that Japan is considering producing their own hydrogen via onsite production adopting the H2IL method. Makes sense as there is not shipping and transportation of the gas needed. Green hydrogen using sea or rain water in any part of the world without tapping into fossil fuel or renewables....

Yeah... as soon as I hear "carbon capture and storage" I know that bullshit is about to be perpetrated.

Very useful information. Energy Green storage is critical. Hydrogen provides reliable power.

How can this channel only have 374K subs ?
