An enormous solar park in the Sahara could soon be exporting electricity to Europe if Tunisia’s government approves an energy company’s request to build it. The 4.5GW mega-project planned by TuNur would pipe electricity to Malta, Italy, and France using submarine cables in the grandest energy export project since the abandoned Desertec initiative. Four years ago, the €400bn Desertec initiative imploded, leaving dreams of a Saharan power battery for Europe in the dust – and a lasting regional wariness.
The resulting solar complex would sprawl over an area three times the size of Manhattan, harnessing the power of the Saharan sun with several towers up to 200m tall. The project’s land would be leased from a local tribe which remains “extremely positive” about the project. Hundreds of thousands of parabolic mirrors would reflect sunlight onto these towers, heating molten salts within them that would in turn boil water, generating enough steam to power turbines that could electrify 2m European homes.
Kevin Sara, TuNur’s chief executive said: “If European governments want to meet the less than two degrees target for global warming, we need to start importing renewables. 60% of Europe’s primary energy is currently imported from Russia or the Middle East. Does the EU really want to be investing in infrastructure that lasts 50 years but which just enables more fossil fuel use?”
The EU is already considering awarding priority status to an underwater cable linking Tunisia with Italy, and TuNur expects construction work on a €5bn plant to begin by 2019 in southwest Tunisia. “We would target delivering power to the European grid via Malta by 2021,” Sara said. The following year, the first of two cables to Italy could be laid, with a French connection up and running by 2024, he added.
Up to 20,000 jobs could be created by the private sector initiative, which unites the London-based solar developer Nur Energie with Tunisian and Maltese developers. Water usage will be restricted to wastewater from a local date tree plantation that would not otherwise be recycled, Sara said. The company also remains willing to supply electricity within Tunisia, which is itself facing power shortages.
