Gulf states look beyond solar with foggy renewable vision

Gulf states look beyond solar with foggy renewable vision
  • Fog harvesting, hydro-electricity and waste-to-energy are among the innovative technologies rolling out in the region
  • The growth of renewable energy will also increase the need for innovative energy storage methods.

LONDON: From “harvesting fog” in Oman to vertical farming in Dubai, Gulf states are looking beyond solar power in the race to develop innovative renewable technologies.
A surge in investment, triggered by a regionwide economic diversification push, is helping to transform the region into an unlikely global hub for renewables innovation.
Dubai utility DEWA this year signed an agreement to study plans to build a 400MW pumped hydro storage power station — using water from Hatta Dam to generate hydro-electric power from water pumped using solar-powered turbines.
It forms part of the Dubai Clean Energy Strategy 2050 which aims to make the emirate a global hub for the green economy and source 75 per cent of its total power output from clean energy.
But it is only one of dozens of major renewable energy projects under way as the huge investment program in solar and offshore wind power in the region extends to other technologies.
“As renewable energy costs decline, technology advances and deployment accelerates around the world, we are entering a new age of energy transformation, with renewable energy becoming a significant driver of economic growth, job creation, and socioeconomic development,” said Adnan Amin, director-general of the International Renewable Energy Agency (IRENA).
Urbanization in the Gulf is also spurring investment as the region’s big cities warm up.
Arup, the London-based engineering consultancy, warns that “arid” cities need to innovate more or become less habitable, as they become drier.
Its report “Cities Alive: Rethinking Cities in Arid Environments,” argues that as air conditioning has enabled the growth of arid cities, many are seeing an “urban heat island effect,” where they become hotter than the surrounding rural areas, increasing water use and accelerating energy consumption.
The report urges cities to adopt measures such as industrial-scale fog and dew harvesting and cooling pavements that can reduce ambient temperatures by up to 7 degrees, as well as building more energy-efficient buildings.
“Cities in arid regions are expected to experience the highest rates of natural population growth and urbanization in the coming century. Yet most are still being planned and designed based on a global city-making paradigm from the 1950s. Cities need to adopt strategies that combine technological innovation with locally adapted and climatically appropriate solutions,” said Hrvoje Cindric, an associate at Arup.
Many cutting-edge renewables technologies are being developed at Masdar City in Abu Dhabi.
Masdar City includes IRENA’s headquarters and the new Masdar Institute and aims to be the first city to operate without fossil-fueled vehicles at street level.
“The region will be exploring different applications but they will always be secondary to wind and solar. This is where the main investment is,” says Zoheir Hamedi, MENA program officer at IRENA.
The Indian Ocean coast of Oman is seen as offering strong potential for wind power, as is Saudi Arabia’s northern quarter.
But Hamedi also points to the potential which bio-energy could offer as a renewable energy source in the region.
On this front, The Emirates Waste to Energy Company, a joint venture between Masdar and Bee’ah, signed terms earlier this year with CNIM on a design, build and operate agreement for the first waste-to-energy facility in the UAE in Sharjah.
Due for completion by 2020, the plant will treat more than 300,000 tons of municipal solid waste each year and generate around 30MW of electricity.
Meanwhile, in January, Dubai Municipality signed a 2.5 billion dirhams ($680,700) contract to build a major new waste-to-energy plant at Warsan which will treat 1.82 million tonnes of waste annually and generate some 185MW of electricity.
Swiss engineering company HZI and Belgian firm Besix Group are expected to start construction this year and the plant is expected to be partially operating by 2020.
Geothermal energy also offers potential in the region, particularly in Saudi Arabia, where a study has highlighted the scope for generating energy from a series of hot springs in the Al-Khouba area of Jizan province in the south west of the country.
Fog harvesting using vast vertical sheets of canvas has proved a useful source of water in areas of scarcity such as Morocco.
The Sustainability Pavilion at the Dubai Expo 2020 will use structures that generate solar energy and capture water from humidity in the air to supply much of its water needs.
Fog technology could be useful in KSA, which combines low rainfall with high per-capita water consumption. Data collected over a year at the Rayda reserve weather station suggested fog could provide a supplementary water supply for the agriculture sector in the south west of the Kingdom, according to research in Water and Environment Journal.
Fog collection projects have also been installed in desert areas worldwide, including Oman and Eritrea.
Meanwhile, to accelerate dew harvesting techniques, the partners of the SunGlacier Challenge recently invited teams of universities worldwide to make water from the air.
The growth of renewable energy will also increase the need for innovative energy storage methods.
“New technologies in energy storage will come to the fore, develop, evolve and become more cost-competitive,” said Dietmar Siersdorfer, chief executive of Siemens Middle East, in a recent report.
Hydrogen is seen as a ripe solution for energy storage from a range of a few kilowatts to gigawatts, for several weeks.
Decentralised systems will also allow power users in industry to produce energy independently for their facilities, reducing transmission losses and carbon emissions.
The Siemens report also highlights energy efficiency as a major area for growth in the region, potentially generating savings of up to 30 per cent.
It also notes the rise in energy efficiency services companies (ESCOs) in the region.
The UAE already has about 30 such companies, more than half of them based in Dubai.
Regional governments have stepped up efforts to remove subsidies in the energy sector in recent years as part of a broader push to wean Gulf economies off oil dependence.
However subsidies remain in place in some countries, which can deter investment in renewables, according to analysts.
“The whole thing needs to be re-thought with a proper plan,” said Rahmat Poudineh, lead senior research fellow, electricity at the Oxford Institute for Energy Studies.
For renewable resources to be integrated economically into the existing energy market, electricity tariffs need to be reformed. Letting renewables compete with existing sources of energy, on a level playing field, is the key issue, he said.
The region also needs to invest in energy efficiency. “Saving 1KWh (kilowatt-hour) of energy is much cheaper than producing 1KWh of clean energy,” Poudineh said.

  • "Biden moving into the White House could drive markets into a bull run more sharply than previous inaugurations," a financial expert says

DUBAI: Investors are expecting a “Biden bounce” in global markets following the inauguration on Wednesday of Joe Biden as the 46th US president.

“History teaches us that we can expect the markets to react favorably to the inauguration of a new US president — and this time around it is likely to be no different,” said Nigel Green, CEO of deVere Group, one of the world’s largest independent financial advisers, with over 80,000 clients and $12 billion under advisement.

“Indeed, Biden moving into the White House could drive markets into a bull run more sharply than previous inaugurations because it is hoped the incoming administration will bring stability and, possibly, a halt to the uncertainty following the fiercely contested election. 

“Investors will also be buoyed by the $1.9 trillion fiscal stimulus announced by Biden, the Federal Reserve’s willingness to support markets, the new president’s multilateral trade agenda and his plans for stepping up the vaccine rollout. All of this will encourage confidence and optimism,” Green said.

Mazen Al-Sudairi, head of research at Riyadh-based financial services company Al Rajhi Capital, agreed with the optimism regarding a “Biden bounce.”

“One of the important outcomes with Biden is stability in the market. But there is also the stimulus factor coupled with the vaccine that is giving an indication of recovery in the market. This perceived unity in the US will be healthy for the global and Saudi market,” he told Arab News.

However, Green said that investors should be cautious for three reasons: “First, a market rally is going to be difficult to sustain indefinitely due to the enormous economic scarring caused by the pandemic.

“The major long-term headwind is mass unemployment, which is hitting demand, growth and investment on Main Street and which, ultimately, will have to impact Wall Street.

“Second, the new administration will have policies that will have an effect on different sectors of the economy. There will be a readjustment period that needs to be taken into account.

“And, third, not all shares are created equal and stock markets are heavily unbalanced at the moment. A handful of sectors are bringing up entire indexes,” he said.
