Azerbaijan subsequent week will garner a lot of the eye of the local weather tech world, and never simply because it is going to host COP29, the United Nation’s large annual local weather change convention. The nation is selling a grand, multi-nation plan to generate renewable electrical energy within the Caucasus area and ship it hundreds of kilometers west, below the Black Sea, and into power–hungry Europe.
The transcontinental connection would begin with wind, photo voltaic, and hydropower generated in Azerbaijan and Georgia, and off-shore wind energy generated within the Caspian Sea. Lengthy-distance strains would carry as much as 1.5 gigawatts of fresh electrical energy to Anaklia, Georgia, on the east finish of the Black Sea. An undersea cable would transfer the electrical energy throughout the Black Sea and ship it to Constanta, Romania, the place it might be distributed additional into Europe.
The scheme’s proponents say this Caspian-Black Sea power hall will assist lower international carbon emissions, present reliable energy to Europe, modernize growing economies at Europe’s periphery, and stabilize a area shaken by conflict. Organizers hope to construct the undersea cable inside the subsequent six years at an estimated value of €3.5 billion (US $3.8 billion).
To perform this, the governments of the concerned international locations should rapidly circumvent a collection of technical, monetary, and political obstacles. “It’s an enormous undertaking,” says Zviad Gachechiladze, a director at Georgian State Electrosystem, the company that operates the nation’s electrical grid, and one of many architects of the Caucasus green-energy hall. “To place it in operation [by 2030]—that’s fairly formidable, even optimistic,” he says.
Black Sea Cable to Hyperlink Caucasus and Europe
The technical lynchpin of the plan falls on the profitable building of a excessive voltage direct present (HVDC) submarine cable within the Black Sea. It’s a formidable job, contemplating that it could stretch throughout almost 1,200 kilometers of water, most of which is over 2 km deep, and, since Russia’s invasion of Ukraine, plagued by floating mines. In contrast, the longest current submarine energy cable—the North Sea Hyperlink—carries 1.4 GW throughout 720 km between England and Norway, at depths of as much as 700 meters.
As formidable as Azerbaijan’s plans sound, longer undersea connections have been proposed. The Australia-Asia PowerLink undertaking goals to supply 6 GW at an enormous photo voltaic farm in Northern Australia and ship a few third of it to Singapore by way of a 4,300-km undersea cable. The Morocco-U.Ok. Energy Venture would ship 3.6 GW over 3,800 km from Morocco to England. An analogous try by Desertec to ship electrical energy from North Africa to Europe finally failed.
Constructing such cables includes laying and stitching collectively lengths of heavy submarine energy cables from specialised ships—the experience for which lies with simply two firms on the earth. In an evaluation of the Black Sea undertaking’s feasibility, the Milan-based consulting and engineering agency CESI decided that the undersea cable may certainly be constructed, and estimated that it may carry as much as 1.5 GW—sufficient to produce over 2 million European households.
However to fill that pipe, international locations within the Caucasus area must generate far more inexperienced electrical energy. For Georgia, that can largely come from hydropower, which already generates over 80 p.c of the nation’s electrical energy. “We’re a hydro nation. We have now quite a lot of untapped hydro potential,” says Gachechiladze.
Azerbaijan and Georgia Plan Inexperienced Vitality Hall
Producing hydropower also can generate opposition, due to the way in which dams alter rivers and landscapes. “There have been some circumstances when buyers weren’t capable of assemble energy vegetation due to opposition of locals or inexperienced events” in Georgia, says Salome Janelidze, a board member on the Vitality Coaching Middle, a Georgian authorities company that promotes and educates across the nation’s power sector.
“It was positively an issue and it has not been completely solved,” says Janelidze. However “to me it appears it’s doable,” she says. “You’ll be able to procure and assemble if you happen to work intently with the native inhabitants and see them as allies slightly than adversaries.”
For Azerbaijan, many of the electrical energy can be generated by wind and photo voltaic farms funded by international funding. Masdar, the renewable-energy developer of the United Arab Emirates authorities, has been investing closely in wind energy within the nation. In June, the corporate broke floor on a trio of wind and photo voltaic tasks with 1 GW capability. It intends to develop as much as 9 GW extra in Azerbaijan by 2030. ACWA Energy, a Saudi power-generation firm, plans to full a 240-MW photo voltaic plant within the Absheron and Khizi districts of Azerbaijan subsequent yr and has struck a cope with the Azerbaijani Ministry of Vitality to put in as much as 2.5 GW of offshore and onshore wind.
CESI is presently working a second examine to gauge the practicality of the complete breadth of the proposed power hall—from the Caspian Sea to Europe—with a transmission capability of 4 to six GW. However that beefier interconnection will doubtless stay out of attain within the close to time period. “By 2030, we are able to’t declare our area will present 4 GW or 6 GW,” says Gachechiladze. “1.3 is life like.”
Indicators of political help have surfaced. In September, Azerbaijan, Georgia, Romania, and Hungary created a three way partnership, based mostly in Romania, to shepherd the undertaking. These 4 international locations in 2022 inked a memorandum of understanding with the European Union to develop the power hall.
The concerned international locations are within the strategy of making use of for the cable to be chosen as an EU “undertaking of mutual curiosity,” making it an infrastructure precedence for connecting the union with its neighbors. If chosen, “the undertaking may qualify for 50 p.c grant financing,” says Gachechiladze. “It’s an enormous funds. It should enhance drastically the monetary situation of the undertaking.” The commissioner answerable for EU enlargement coverage projected that the union would pay an estimated €2.3 billion ($2.5 billion) towards constructing the cable.
Whether or not subsequent week’s COP29, held in Baku, Azerbaijan, will assist transfer the plan ahead stays to be seen. In preparation for the convention, advocates of the power hall have been taking worldwide journalists on excursions of the nation’s power infrastructure.
Looming over the undertaking are the safety points threaten to thwart it. Delivery routes within the Black Sea have turn into much less reliable and protected since Russia’s invasion of Ukraine. To the south, tensions between Armenia and Azerbaijan stay after the latest conflict and ethnic violence.
With the intention to enhance relations, many advocates of the power hall want to embody Armenia. “The cable undertaking is within the pursuits of Georgia, it’s within the pursuits of Armenia, it’s within the pursuits of Azerbaijan,” says Agha Bayramov, an power geopolitics researcher on the College of Groningen, within the Netherlands. “It would enhance the prospect of them dwelling peacefully collectively. Possibly they’ll say, ‘We’re answerable for European power. Let’s put our egos apart.’”
