Geoff_H Posted December 8, 2021 Share Posted December 8, 2021 It looks like Twiggy is backing hydrogen. Liddell power station has been making hydrogen by electrolysis since the 1971. Just a much larger scale. 1 Link to comment Share on other sites More sharing options...
Flightrite Posted December 8, 2021 Share Posted December 8, 2021 The bulge was typical of the era built by the Pom’s, they liked ugly! The cockpit door was narrow so access into the office was tight and an ergonomic mess! Superb handling though👍 Link to comment Share on other sites More sharing options...

The only reason I can see him doing this for is to lower the carbon emissions of steel manufacture. He's hoping to combine a healthy dose of government funds with an industry opportunity.

I have worked in WA and met a few people that have worked with Twiggy. He is a great guy and is truly interested in the community. His grandfather Lord Forest was a great guy also, he did a lot to develop WA. He doesn't have an office he sits in a big room with all other employees. He does huge effort promoting the aboriginal.peoples lifestyle. 1 Link to comment Share on other sites More sharing options...
Ian Posted December 8, 2021 Share Posted December 8, 2021 It wasn't meant to be disparaging I think that he's done a great job of building wealth in Australia. Steel production is currently very carbon intensive, Twiggy's business revolves around iron ore. This is a problem for his business model. You can make mostly green steel using Hydrogen by directly reduced iron (DRI) and then further processing it in an electric arc furnace. This is viable if H2 becomes cheap enough which it may do, the most efficient plant for the production of H2 is estimated to product H2 for about US 60c/kg over the life of the plant. This doesn't include power or storage. So you need lots of cheap power using something like solar to make this viable. Australia has lots of space and a goodly amount of sunshine so this can make lots of cheap power some of the time. In theory this might provide energy for the above. All this doesn't change the fact that H2 sucks a bit as a transport fuel for the reasons stated, though it might become a sufficiently cheap feedstock for processes like this on https://www.pnas.org/content/116/26/12654 Ironically I lot of these processes require CO2 as a feedstock. Also Twiggy did admit in 2011 that Forteque Metals had never paid any Tax https://www.abc.net.au/news/2011-11-09/fortescue-mining-company-tax/3655270 So I wouldn't expect him to do anything without getting the maximum return from Government.

Geoff_H Posted December 9, 2021 Share Posted December 9, 2021 One of the biggest carbon emitters are mines! One particular iron ore mine, a confidentially agreement prevents me from disclosing much) burns 3,000,000 litres of oil per month. Hydrogen powered machinery would prevent this diesel/explosives from emitting. There must be many mines also with high emssions. Most electricity is from burning natural gas from the pipelines in gas turbines (hence my involvement). Link to comment Share on other sites More sharing options...

onetrack Posted December 9, 2021 Share Posted December 9, 2021 (edited) The outback mines in W.A. are rapidly moving over to green energy sources, solar in particular is such low cost, it's a no-brainer. Being a diesel supplier to a remote mine is no longer a massive growth business, and it will become a business with little future. https://www.abc.net.au/news/rural/2021-11-15/green-mines-a-renewable-energy-evolution/100613266 Edited December 9, 2021 by onetrack 1 Link to comment Share on other sites More sharing options...

He said wind cost 4 times gas turbines. Never quite sure what he was about but he did say it was an expensive installation (interest on investment?,) And you still need to have a gas or diesel power plant. The overwhelming amount of energy is in trucks and loaders....a solar panel on the roof of the trucks, or maybe a wind turbine? One panel in a sunlit day produces enough energy to drive a Tesla 4km. 5MW motor on a dump vehicle may be just too much LoL 1 Link to comment Share on other sites More sharing options...

They are currently diesel/electric (the electric motors give them 100% torque at zero - perfect for optimum startability and there is no highway cycle. 1 Link to comment Share on other sites More sharing options...

Old Koreelah Posted December 9, 2021 Author Share Posted December 9, 2021 Modern sails can propel vessels at big angles off the prevailing wind. So why don’t commercial ships use wind? As I’ve been saying for yonks: oil is too cheap. Link to comment Share on other sites More sharing options...

If controlled buy AI, neither of your objections should be of concern. Fuel is a critical facto with ships, but canvas and rigging has obvious issues with training, fire and loading/unloading cargo as well as hull shape. What was trialled a few years ago were vertical cylinder "sails" which avoided those problems. When the cylinders were spinning they acted as sails. Some were fitted to cruise ships as a means of reducing their fuel consumption. Similar cylinders have also been trialled as aircraft wings. The trend didn't catch on, but I'm not sure why; perhaps the fuel lost in spinning them offset the gain through sailing. Link to comment Share on other sites More sharing options...

Large parachute type sails were developed as well. https://en.wikipedia.org/wiki/SkySails Wind suffer from the same issues on the sea as on land, intermittency so the gains aren't as large on some routes as they are on others.
