Today we’ll take a look at three impressive energy-saving projects that are set to launch in the coming years.

The Great Solar Wall in Kubuqi Desert (China)

The almost lifeless Kubuqi Desert in Inner Mongolia is now being given a new lease on life thanks to a project unofficially called the Great Solar Wall, which is based on the installation of solar photovoltaic panels. The construction is part of China’s multi-year plan to create an area designed to generate enough energy to power Beijing.

The project, expected to be completed in 2030, will be 400 kilometers (250 miles) long, 5 kilometers (3 miles) wide, and have a maximum generating capacity of 100 gigawatts.

Amaravati (India) – the 100% sustainable city of the future

The new administrative capital of the Indian state of Andhra Pradesh, Amaravati is now becoming a global environmental leader. Architects Foster + Partners have designed the master plan for the new government complex, which is the centrepiece of the 217 square kilometre city. Situated on the banks of the Krishna River, the new city is strategically located to benefit from an abundant supply of fresh water and will be one of the most environmentally sustainable in the world. Inspired by Lutyens’ New Delhi and New York’s Central Park, a clearly defined green spine runs the length of the city, providing the foundation for the environmental strategy of the master plan, with at least 60% of the area covered by greenery or water. The city has been designed to the highest standards of sustainability, using the latest technologies currently being developed in India, such as photovoltaics. The transport strategy includes electric vehicles, water taxis and dedicated bike routes, as well as shaded streets and squares that will encourage people to walk around the city.

Viking Libra (Italy) – the world’s first hydrogen-powered cruise ship

The largest Italian shipbuilder Fincantieri and the cruise line Viking announced in early April the imminent launch of Viking Libra, the world’s first hydrogen-powered cruise ship capable of operating with zero emissions. Viking Libra, already under construction at Fincantieri’s Ancona shipyard, is scheduled for delivery in late 2026.

Viking Libra will have a gross tonnage of approximately 54,300 tons with 499 staterooms that can accommodate 998 guests. Although considered a sister ship to Viking’s award-winning ocean-going fleet, she will feature a propulsion system based in part on liquefied hydrogen and fuel cells. This hybrid propulsion system will allow the vessel to navigate and operate with zero emissions, allowing it to reach even the most environmentally sensitive areas.
