Rio Tinto’s Big Energy Project Attracts Multiple Bidders
The title of this post, is the same as that of this article on Mining Technology.
The article has this subtitle.
The company seeks to offset its power consumption with a massive renewable plant.
These two paragraphs introduce the project.
British and Australian mining giant Rio Tinto has attracted multiple bids for a massive renewable power infrastructure project.
The company currently seeks suppliers to build up to 4GW of renewable generation for its alumina and aluminium operations in Queensland, Australia. Speaking to the Melbourne Mining Club, the company’s CEO of Australia, Kellie Parker, said that it had received proposals for “a lot more than 4GW”. Parker also said that construction of the project “would not be easy” due to the cost of construction for Australian projects.
In the UK, we may talk of wind farms like Hornsea, which could produce 6 GW, but the Aussies can produce similar amounts of energy from the sun.
This will be the fourth major renewable power development in Australia to be announced in the last few months.
- The Asian Renewable Energy Hub could generate up to 26 GW in Western Australia.
- I wrote about Andrew Forrest’s ambitions in Andrew Forrest Snaps Up Pilbara And Gascoyne Cattle Stations For Green Energy Production.
- The Australia-Asia Power Link will export solar power from Australia to Singapore.
Australia is certainly looking to power the world.
Energy Storage
Rio Tinto are also talking about energy storage, as other systems of this type and size do. Could this be one of a number of Australian projects mentioned on the Highview Power web site?
BHP To Trial Battery Locos On Pilbara Iron Ore Network
The title of this post, is the same as that of this article on Railway Gazette.
The article summarised all the battery-electric locomotives ordered to bring the iron ore to the coast by mining companies; BHP, Fortescue, Rio Tinto and Roy Hill.
The article indicates some of the innovative operations that will be tried. This is a sentence from the article.
A key element will be to assess the potential for capturing regenerated braking energy on the loaded downhill runs, and storing it to power empty trains back uphill to the mines.
I would hope that the South Wales Metro, the Buxton branch and the East Kilbride branch will use similar energy conservation techniques.
Aviva To Eject Company Directors If Climate Goals Are Not Met
The title of this post is the same as that of this article in The Sunday Times.
Increasingly, I am seeing company boards taking decisions, that will cut their company’s carbon footprint.
Only yesterday, I wrote Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway, which was about First Group’s moves to decarbonise some of their locomotive-hauled trains.
I have also written about BHP, BP, Fortescue, Go-Ahead and Rio-Tinto taking action to decarbonise.
It does seem that some company boards are following Aviva’s guidance, but then it is in the directors own interest.
Many directors of large companies own shares and in a big public company, these are publicly traded.
I would suspect, that if a company board, do the right thing in terms of decarbonisation, that the share price will rise.
So by following the accepted climate science, they are actually helping themselves.
If they don’t believe that, then aggressive shareholders from Norwich will punish them.
Rio Tinto Orders Wabtec FLXdrive Battery Locomotives To Reduce Emissions
The title of this post, is the same as that of this press release from Wabtec.
This is the introductory paragraph.
Wabtec Corporation (NYSE: WAB) and Rio Tinto announced today an order for four FLXdrive battery-electric locomotives to support sustainable operations of the mining company’s rail network in the Pilbara region of Western Australia. The 100-percent, battery-powered locomotive will help Rio Tinto’s effort to achieve a 50-percent reduction in Scope 1 and 2 carbon emissions by 2030.
Some other points from the press release.
- The locomotives have 7 MWh batteries.
- The first locomotive will be delivered in 2023.
- The FLXdrive is anticipated to reduce the company’s fuel costs and emissions in percentage by double digits per train.
This paragraph describes how the FLXdrive locomotives will be used.
The mining company plans on using the locomotives in multiple applications including as a shunter in the railyard and ultimately in mainline service. In mainline operations, Rio Tinto currently uses three diesel-electric locomotives in a consist to pull trains with 240 cars hauling about 28,000 tons of iron ore. The FLXdrives will transition from the diesel locomotives in mainline service to form a hybrid consist, and recharge during the trip through regenerative braking and at charging stations. Wabtec’s next generation energy-management software system will determine the optimal times to discharge and recharge the batteries along to route ensuring the most fuel-efficient operation of the entire locomotive consist during the trip.
I can see this approach leading to even bigger fuel and emission savings.
Especially, if Wabtec developed a compatible locomotive, that was powered by hydrogen.
This was rumoured in FLXdrive ‘Electrifies’ Pittsburgh, where a partnership between Carnegie-Mellon University (CMU), Genesee & Wyoming and Wabtec to create the Freight Rail Innovation Institute was described.
Conclusion
There certainly seems to be a consensus between some of the world’s largest mining and rail companies about the future of heavy freight trains to support the mining industry.
