The Intertubes completely lit up earlier at this time, when the Australian authorities lastly green-lighted the large, lengthy awaited Australia-Asia Energy Hyperlink photo voltaic power mission. 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 non-public 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 Vitality By (Very) Lengthy Undersea Cable: Not A Dream

The thought of transporting photo voltaic power by undersea cable is a comparatively new twist on an previous thought. The usage of submarine cables for transporting renewable power 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 mission circumnavigating Africa, for instance, is 45,000 kilometers (about 27,961 miles) lengthy. “The deep-sea cable mission will join 32 different African nations and instantly help financial growth in Africa, fostering additional progress of 4G and 5G and elevated broadband penetration to thousands and thousands of individuals and companies throughout the continent,” Africa Enterprise Insider reported final February.

By comparability, the undersea photo voltaic power cable proposed by SunCable is available in on the modest scale of simply 4,300 kilometers (about 2,671 miles).

Alternatively, energy cables and fiber optic cables aren’t the identical factor. As an influence cable, the SunCable mission is by far essentially the most bold mission of its variety. So far, the Danish-British Viking Hyperlink mission is billed because the longest undersea energy cable on the planet with a complete size of 765 kilometers (475 miles).

Know-how apart, undersea cables usually fall sufferer to break, whether or not from passing anchors and fishing gear, deliberate sabotage, or collateral harm from geopolitical tensions. Nonetheless, that has not stopped stakeholders from investing in new cable initiatives. Earlier this yr, the agency MarketsandMarkets ran the numbers on submarine cables and reported that the undersea cable market is anticipated to achieve $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 Vitality Love With Singapore

As for the small print, the SunCable AAPowerLink mission surfaced on the CleanTechnica radar 5 years in the past. In its present iteration, AAPowerLink will draw on the wealthy photo voltaic power assets of Australia’s Northern Territory, with plans for setting up an enormous photo voltaic array within the Barkly area.

The clear kilowatts can be shunted to Darwin by overhead transmission strains earlier than heading out to Singapore by undersea cable on a 24/7 foundation, with an help from on-site power storage methods.

SunCable notes that the 800-kilometer overhead line will “typically” observe an current railway hall, with the intention of decreasing development prices and mitigating environmental impacts.

“The mission contains the event of the world’s greatest built-in renewable power and battery storage facility within the coronary heart of the Northern Territory which may over a number of phases have a capability of as much as 6GW of renewable power to Darwin and Singapore,” SunCable provides.

That’s only for starters. SunCable is billing AAPowerLink as a flagship mission, with extra to come back.

“Now we have a transparent and bold imaginative and prescient: to harness Australia’s unbelievable renewable power potential to energy cities, drive new economies, and help communities all through the Asia Pacific area,” SunCable explains.

In help 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 “crucial enabler of SunCable and different renewable transmission initiatives in Australia and past.”

Large Photo voltaic Vitality Undertaking Will get The Edge On Nuclear Vitality

Reuters was among the many many information organizations to catch the most recent information about AAPowerLink at this time. Reporter Renju Jose famous that the mission is going through opposition from nuclear power stakeholders, who argue that Australia can’t exchange its coal energy crops 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 abruptly wakes up at some point and decides to ban photo voltaic power, AAPowerLink is on a quicker observe.

In a press launch saying the approval, SunCable famous that the mission has now sailed by way of the Commonwealth EPBC Act in addition to the Surroundings Safety Act of the Northern Territory, “paving the best way for the following section of growth to ship industrial-scale electrical energy to clients in Darwin and Singapore.”

Don’t maintain your breath for all that photo voltaic power to start flowing. Though AAPowerLink has gotten previous a years-long environmental overview course of, a Last Funding Resolution is just not anticipated till the start of 2027. If all goes based on plan, the photo voltaic power will start flowing in 2030.

Within the meantime, SunCable lists the next steps to come back, any one among which may complicate the timeline:

• Persevering with negotiations of Indigenous Land Use Agreements (ILUAs) with Conventional Homeowners throughout the mission footprint within the Northern Territory;

• Participating with Singapore’s Vitality Market Authority on the conditional approval utility for the subsea cable interconnector part of the mission; and

• Participating with the Indonesian Authorities on regulatory and allowing issues to show the subsea route inclusive of information and hydrographic data-sharing.

What About The Vitality 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 Might, with an help from his Grok Ventures agency and the net-zero specialist Quinbrook Infrastructure Companions.

Whereas the bold mixture of photo voltaic power and undersea cable have generated a lot of the media buzz over the AAPowerLink mission, power storage can be going to be a key ingredient within the mission.

With that in thoughts, hold your eye on one other Grok Ventures portfolio firm, Antora Vitality. The California startup is neck deep within the discipline of lengthy length power storage innovation. The US Division of Vitality defines lengthy length 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 power, such because the AAPowerLink mission, the Vitality 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 Vitality Division to refine its lengthy length “thermal battery” for industrial use, so keep tuned for extra on that.
