Egypt’s new capital city is getting a $1 billion skyscraper which will be powered by clean hydrogen, according to the Saudi-controlled real estate firm that’s building it.

The temporarily named New Administrative Capital (NAC), initiated by President Abdel Fattah al-Sisi, is a new city situated thirty miles east of Cairo. It aims to accommodate Egypt’s growing population, which now exceeds 105 million.

Magnom Properties, a subsidiary of Saudi industrial group Rawabi Holding, is building the 50-storey Forbes International Tower, which will be an office building, according to Reuters.

The firm will break ground on construction soon, and it is expected to be completed by 2030, according to Karim Dayhoum, the company’s executive director of projects.

“We want to offer our tenants and our buyers and investors the opportunity to utilize the facilities and amenities across the region,” Dayhoum said, per Reuters. “It’s a network of sophisticated office space.”

The firm is seeking to later build sister buildings in Dubai and Riyadh.

The building is an innovation in the region, as it plans to be the first net-zero carbon tower in the Middle East and North Africa.

The tower’s Instagram page says it the world’s first tower to officially register for the International Living Future Institute (ILFI) Zero Carbon Certification.

Clean hydrogen is produced with minimal or zero carbon emissions, often through renewable energy or advanced carbon capture technologies.

Solar panels will also be fixed on the building’s exterior, which will aim to produce 25 percent of the electricity it consumes.

Dayhoum said: “We’re trying to completely eliminate any sort of reliance on utilities.”

The tower highlights Egypt’s ambition to establish itself as a green energy hub in the region. However, Reuters notes that clean hydrogen has not yet been proven at scale.

It will be built in partnership with French artist Richard Orlinksi, who Magnom have partnered with before, according to the tower’s website.

The building will be financed through various debt equity instruments, Magnom’s chief investment officer Ahmed Kassem said.

“We’re still at a group level discussing whether to retain full ownership of the building,” Kassem added.

The NAC is one of al-Sisi’s megaprojects that aim to develop the country’s economy. It will span 270 square miles and is expected to eventually house around 6.5 million people.

Some government functions have already started the transition from Cairo to the NAC, which has yet to be given a formal name.

Critics have expressed concern about the expense of the project—which is estimated to cost up to $60 billion to develop—as the country goes through a period of economic downturn.

Meanwhile, ordinary Egyptians continue to suffer from a cost of living crisis
