Saudi ACWA Power’s investment in Africa reaches $7bn, CEO says

  • Marco Arcelli said all the investments revolve around renewables
  • Recent agreements with the Egyptian and Tunisian governments underscore ACWA Power’s commitment to advancing green hydrogen projects and expanding its impact in Africa

RIYADH: Saudi ACWA Power has invested $7 billion in Africa to date, according to the electric power generation company’s CEO.

Speaking during a panel discussion titled “Powering Africa: What is the Future of Energy Investments” during the Future Investment Initiative New Africa Summit in Riyadh, Marco Arcelli said that all those investments revolve around renewables.

This falls in line with the firm’s position as the leading private investor in the continent’s renewable energy sector.

It also aligns with the company’s goal to triple its business size announced in 2023 and expand worldwide, driven by its mission to deliver affordable and reliable energy solutions that foster economic and social development.

“Our experience, ACWA Power is probably the largest energy transition company today, certainly a leading investor in Africa. We have invested more than $7 billion today, 100 percent of that is renewables,” Arcelli said.

“I’m not saying the gas is not part of the transition, in fact, it is because countries like the countries in Africa that are emerging, they need all the energy that they can,” the CEO added.

He went on to say that there is a lot to be done and that the cheapest, fastest, and most secure way to do that is through renewables.

“But certainly, when the economy is growing at the speed that is growing in Africa, you need a complement, so you need the gas and potentially other sources,” Arcelli said.

The world’s largest private water desalination company has also announced that its Redstone Concentrating Solar Power plant in South Africa has reached 50 MW and is set to achieve its full 100 MW capacity in the coming days.

The project will provide clean energy to nearly 200,000 households while significantly reducing carbon emissions. 

Recent agreements with the Egyptian and Tunisian governments underscore ACWA Power’s commitment to advancing green hydrogen projects and expanding its impact in Africa.

Also speaking during the same panel, Kola Karim, group managing director and CEO of Shoreline Group, said looking at the dynamics of Africa, it is evident that it cannot be benchmarked at the same standards as other continents.

“We talk about the industrial revolution in the world, the Western nations have had their first, second, third and Africa has not had its first,” Karim said.

“So, my view is Africa’s blessed with a lot of natural resources, gas is one of them,” he added.

Also present at the panel, Osa Igiehan, CEO of Heirs Energies Limited, said that Africa’s energy future is going to be dominated by gas and renewables.

“Gas is very key. It’s a transmission fluid and we have plenty of it, but renewables is going to be very compelling because it offers us opportunities to address energy gaps in areas that are underserved today,” Igiehan said.

Vera Songwe, chair and founder of Liquidity and Sustainability Facility, was also partaking in the panel, in which she said that there is a question about growth and how fast and how far Africa wants to grow.

“If Africa wants to grow today, our GDP (gross domestic product) is about $3.2 trillion and we need to do a lot more and a lot faster than we need all the technologies we can harness,” Songwe said.

“Africa is already at a tipping point on the transition; 60 percent of Africa’s energy is renewable because of hydro. We have a lot of the economies, they are using hydro,” she added.

Riham Elgizy, CEO of Voluntary Carbon Market, said that 43 percent of Africans do not have access to electricity.

“What century are we in? This is very important for the continent that we finance; be it renewable, be it gas, be it others. All options are on the table,” Elgizy said.

“We need to look at it from a lens of carbon markets and how we can utilize that to scale projects on finance because the major problem in Africa right now is financing. So, this is how to utilize different tools. This is very important to look at and how to be innovative in neutralizing those,” she added.

In September, Saudi Arabia’s FII announced that it would host two summits before its eighth edition, set to take place in Riyadh from Oct 29 to 31. 

Both being held for the first time, one gathering will center on Africa, while the second, titled the “Horizon Summit,” occurring on Oct. 28, will focus on women empowerment and will be chaired by Princess Reema bint Bandar, the Saudi ambassador to the US. 

Under the theme “Infinite Horizons: Investing Today, Shaping Tomorrow,” this edition of the forum will facilitate discussions on how investments can drive a thriving and sustainable future, pushing the boundaries of what is possible for humanity. 

This aligns with FII’s mission to create a purposeful present and a promising future, as well as its vision to bring together the brightest minds and most promising solutions to serve humanity.

How KAUST is transforming waste into wealth

  • Researchers target $275m market with waste-to-value algae innovation

RIYADH: Turning food waste into a valuable industrial product may sound improbable, but scientists at King Abdullah University of Science and Technology are proving it is possible — using algae that has existed for millions of years. 

Last month, researchers at the university unveiled a sustainable method that harnesses an ancient red microalga to reduce food waste in the Kingdom while producing a high-demand natural pigment.

The study was led by bioengineering student Mauricio Masson, with support from Michael Fox, assistant professor of marine science, alongside researchers from KAUST and the Arizona Center for Algae Technology and Innovation. The international team included Kyle Lauersen, KAUST associate professor and lead author of the study.

The research highlights a “sustainable bioprocessing” approach, demonstrating how an aquatic plant can convert chocolate factory waste into C-phycocyanin — a blue pigment with a global market expected to reach $275 million over the next four years.

“Our research focused on an extremophilic red alga that can thrive in harsh conditions and efficiently consume sugars and nutrients found in food waste streams,” said Lauersen.

Lauersen is an associate professor and chair of the bioscience and bioengineering programs in the Biological and Environmental Sciences and Engineering Division at KAUST. He explained that a key objective of the study was to show that food waste — often discarded or sent to landfills — can be repurposed as a feedstock for producing high-value compounds, including natural pigments and proteins, through algae-based bioprocesses.

“Our main goal was to develop an environmentally friendly approach to turn waste into useful products that have the potential to be scaled,” Lauersen told Arab News.

Did you know?

• By 2030, the global market for C-phycocyanin is projected to exceed $275 million, reflecting growing demand across food, health, and industrial sectors.

• C-phycocyanin has demonstrated potential benefits in antioxidation, inflammation, cancer research, antimicrobial activity, neurodegeneration, diabetes management, and wound healing.

• As a natural pigment, C-phycocyanin offers a healthier alternative to synthetic food colorants and is approved by the US FDA for use in food products.

He added: “Algae are especially well suited for this because they grow quickly, require relatively few resources, and can metabolize a wide range of organic compounds.”

The red microalga Galdieria yellowstonensis feeds on chocolate waste rich in residual sugars, producing a protein-dense biomass that contains C-phycocyanin, according to KAUST. The pigment is widely used as a natural food coloring — found in products such as ice cream and blue-colored beverages — as well as in cosmetics and pharmaceuticals.

Beyond the study’s original goals, researchers also discovered that elevated levels of carbon dioxide significantly enhance algae growth, even though CO₂ is typically considered a byproduct of microbial sugar consumption.

Another major outcome of the research is its potential to reduce land pollution by transforming food waste into a nutrient source for algae, offering a sustainable alternative to disposal.

KAUST believes the findings could positively impact Saudi Arabia’s economy by helping food manufacturers lower production costs while addressing environmental concerns.

“The species we studied can grow on waste streams that are unsuitable for conventional crops or microorganisms,” said Lauersen.

“This makes algae an attractive platform for circular economy solutions, where waste is transformed directly into valuable materials rather than being treated as a disposal problem.”

The research effort is ongoing. Scientists at KAUST are currently collecting chocolate waste locally and plan to scale up the process using other industrial waste streams available across the Kingdom. The initiative aims to support companies in transitioning toward a circular carbon economy while contributing to Saudi Arabia’s green agenda.

“Food waste is a major global challenge, contributing to greenhouse gas emissions, resource inefficiency, and environmental degradation,” said Lauersen.

“By recycling waste into useful products, we can reduce pressure on landfills, lower emissions, and make better use of existing resources.”

“These types of solutions are essential as industries worldwide face growing demands to become more sustainable and climate resilient, especially in the Middle East, which relies on heavily on imports.”
