The Intertubes completely lit up earlier right now, when the Australian authorities lastly green-lighted the huge, lengthy awaited Australia-Asia Energy Hyperlink photo voltaic vitality venture. Beneath the purview of the startup SunCable, AAPowerLink will join the nation’s huge photo voltaic assets to the energy-hungry island of Singapore by undersea cable. The personal sector enterprise could seem quixotic at first look, however the expertise items are in place — it’s only a matter of subsequent steps.
Photo voltaic Power By (Very) Lengthy Undersea Cable: Not A Dream
The concept of transporting photo voltaic vitality by undersea cable is a comparatively new twist on an outdated thought. The usage of submarine cables for transporting renewable vitality is commonplace, partly by advantage of the offshore wind trade.
Lengthy undersea cables are additionally commonplace and they’re getting longer, particularly within the discipline of information transmission. The brand new Meta undersea cable venture circumnavigating Africa, for instance, is 45,000 kilometers (about 27,961 miles) lengthy. “The deep-sea cable project will connect 32 other African countries and directly support economic development in Africa, fostering further growth of 4G and 5G and increased broadband penetration to millions of people and businesses across the continent,” Africa Enterprise Insider reported final February.
By comparability, the undersea photo voltaic vitality cable proposed by SunCable is available in on the modest scale of simply 4,300 kilometers (about 2,671 miles).
Then again, energy cables and fiber optic cables aren’t the identical factor. As an influence cable, the SunCable venture is by far essentially the most bold venture of its sort. Up to now, the Danish-British Viking Hyperlink venture is billed because the longest undersea energy cable on the planet with a complete size of 765 kilometers (475 miles).
Expertise apart, undersea cables typically fall sufferer to break, whether or not from passing anchors and fishing gear, deliberate sabotage, or collateral injury from geopolitical tensions. Nonetheless, that has not stopped stakeholders from investing in new cable initiatives. Earlier this 12 months, the agency MarketsandMarkets ran the numbers on submarine cables and reported that the undersea cable market is predicted to succeed in $27 billion by 2029, up from $18.2 billion in 2024. The demand for energy cables is driving the market, in addition to the demand for fiber optic cables.
Australia To Share The Photo voltaic Power Love With Singapore
As for the main points, the SunCable AAPowerLink venture surfaced on the CleanTechnica radar 5 years in the past. In its present iteration, AAPowerLink will draw on the wealthy photo voltaic vitality assets of Australia’s Northern Territory, with plans for establishing an enormous photo voltaic array within the Barkly area.
The clear kilowatts can be shunted to Darwin by overhead transmission traces earlier than heading out to Singapore by undersea cable on a 24/7 foundation, with an help from on-site vitality storage methods.
SunCable notes that the 800-kilometer overhead line will “generally” comply with an present railway hall, with the intention of decreasing development prices and mitigating environmental impacts.
“The project includes the development of the world’s biggest integrated renewable energy and battery storage facility in the heart of the Northern Territory which could over multiple stages have a capacity of up to 6GW of renewable energy to Darwin and Singapore,” SunCable provides.
That’s only for starters. SunCable is billing AAPowerLink as a flagship venture, with extra to return.
“We have a clear and ambitious vision: to harness Australia’s incredible renewable energy potential to power cities, drive new economies, and support communities throughout the Asia Pacific region,” SunCable explains.
In assist of that purpose, the corporate is laying plans for in-house cable manufacturing to make sure speedy manufacturing. SunCable anticipates that its manufacturing operation can be a “critical enabler of SunCable and other renewable transmission projects in Australia and beyond.”
Large Photo voltaic Power Mission Will get The Edge On Nuclear Power
Reuters was among the many many information organizations to catch the most recent information about AAPowerLink right now. Reporter Renju Jose famous that the venture is dealing with opposition from nuclear vitality stakeholders, who argue that Australia can’t substitute its coal energy vegetation by 2050 with out lifting a present ban on nuclear development.
That’s going to be a troublesome row to hoe. Until the Commonwealth Authorities immediately wakes up sooner or later and decides to ban photo voltaic vitality, AAPowerLink is on a sooner monitor.
In a press launch asserting the approval, SunCable famous that the venture has now sailed via the Commonwealth EPBC Act in addition to the Setting Safety Act of the Northern Territory, “paving the way for the next phase of development to deliver industrial-scale electricity to customers in Darwin and Singapore.”
Don’t maintain your breath for all that photo voltaic vitality to start flowing. Though AAPowerLink has gotten previous a years-long environmental evaluation course of, a Remaining Funding Choice shouldn’t be anticipated till the start of 2027. If all goes in line with plan, the photo voltaic vitality will start flowing in 2030.
Within the meantime, SunCable lists the next steps to return, any one in every of which might complicate the timeline:
• Persevering with negotiations of Indigenous Land Use Agreements (ILUAs) with Conventional Homeowners throughout the venture footprint within the Northern Territory;
• Partaking with Singapore’s Power Market Authority on the conditional approval utility for the subsea cable interconnector element of the venture; and
• Partaking with the Indonesian Authorities on regulatory and allowing issues to show the subsea route inclusive of information and hydrographic data-sharing.
What About The Power Storage?
The newly issued approval for AAPowerLink represents fairly a turnaround for SunCable. The agency was initially co-founded by Andrew Forrest of Fortescue Metals Group and the equally deep-pocketed Mike Cannon-Brooks of Atlassian. A battle royal later ensued and the corporate went into voluntary administration. Cannon-Brooks lastly emerged with the corporate in hand final Could, with an help from his Grok Ventures agency and the net-zero specialist Quinbrook Infrastructure Companions.
Whereas the bold mixture of photo voltaic vitality and undersea cable have generated a lot of the media buzz over the AAPowerLink venture, vitality storage can be going to be a key ingredient within the venture.
With that in thoughts, preserve your eye on one other Grok Ventures portfolio firm, Antora Power. The California startup is neck deep within the discipline of lengthy period vitality storage innovation. The US Division of Power defines lengthy period as 10 hours at naked minimal, far outdoing the present 4-6 hour capability of standard lithium-ion battery arrays. For grid storage and different industrial-scale customers of wind or photo voltaic vitality, such because the AAPowerLink venture, the Power Division has its eye on even longer durations lasting days, weeks, months, and complete seasons.
When CleanTechnica final checked into Antora, it was working with the Power Division to refine its lengthy period “thermal battery” for industrial use, so keep tuned for extra on that.
