How Oman is embracing agrivoltaics for a sustainable future
Beneath the bright Omani sun, a quiet transformation is taking root. Fields that once lay exposed to the harsh desert heat may soon be shaded by rows of solar panels - not as a replacement for agriculture, but as its ally. This is agrivoltaics: a forward-thinking approach where farming and solar energy generation go hand in hand, promising a new model of land use for arid regions like Oman. Agrivoltaics - the practice of combining solar panels with agriculture on the same land - was first proposed in 1981 by German physicist Adolf Goetzberger as a solution to the competing demands for land, food, and energy (AgTech Digest, 2024). By shading crops and reducing water loss while generating electricity, agrivoltaics is particularly suited to arid, sunny regions like Oman. Globally, the market is expanding rapidly: Global Market Insights (2024) valued the agrivoltaics sector at $6.3 billion, forecasting a compound annual growth rate (CAGR) of 5.6% through 2034. A UK-based study by the University of Sheffield (2024) further highlighted that deploying agrivoltaics on 20,272 km² of high-grade farmland could generate around 338 terawatt-hours of electricity annually, while maintaining agricultural output - a model with clear potential for countries seeking sustainable land use. For Oman, where Vision 2040 prioritises both sustainable agriculture and renewable energy, agrivoltaics offers an opportunity to make its land work smarter: producing food, conserving water, and harvesting energy from the sun. The concept is simple but powerful. By combining agriculture with solar installations, land can serve two purposes at once; growing crops while generating clean electricity. The panels provide shade that reduces evaporation and heat stress for plants, while the ground below helps cool the panels, improving their efficiency. It's an elegant solution to some of the most pressing challenges facing Oman today: water scarcity, food security, and the urgent need to expand renewable energy. Earlier this year, Oman announced plans for its first large-scale agrivoltaics project: a 300-acre agri-solar park backed by an investment of over RO 61 million. Singapore's V-Plus Agritech will contribute advanced technologies, including vertical aquaponics and circular farming systems. The project supports Oman's Vision 2040, which calls for economic diversification and greater sustainability across all sectors. Few countries are better suited to agrivoltaics than Oman. The Sultanate enjoys year-round sunshine — an abundant natural resource that remains underutilized. At the same time, water is precious, and conventional agriculture faces rising challenges due to climate change. In this context, the ability to grow food while producing clean power and conserving water represents a major opportunity. The country's recent momentum in solar energy supports this path. By the end of 2025, Oman's small and mid-scale solar capacity is expected to reach about 130 MW, and the launch of giga-scale solar projects signals growing ambition. Integrating agrivoltaics into this mix could multiply the benefits, generating local jobs, enhancing food resilience, and positioning Oman as a regional leader in sustainable land use. For Oman, agrivoltaics is more than a technological innovation — it's part of a broader journey toward a balanced, sustainable future where land works harder and smarter for the people who depend on it. If successful, the first projects could pave the way for more; transforming the landscape of farming, energy, and opportunity in the years to come.

CEO TALK: From boardroom to bedrock: Decarbonising the planet, one rock at a time
WALAA HAMDAN MUSCAT, JUNE 1 In the escalating global battle against climate change, few figures personify purpose-driven entrepreneurship as compellingly as Talal Hasan, Founder and CEO of Omani climate-tech startup 44.01. At the heart of his venture lies a deceptively simple yet world-changing mission: to remove as much carbon dioxide (CO₂) from the atmosphere as possible—permanently, affordably, and at scale. Hasan's personal and professional transformation began not in a laboratory, but with a headline in 2018 that revealed the grim reality that Oman's seas contained the world's largest known ocean 'dead zone'—a vast, oxygen-depleted area where marine life could no longer survive. At the time, Hasan was working in venture capital at IDO Investments, backing high-growth tech and energy startups. But that sobering report shifted his trajectory entirely. 'I grew up as an environmentalist,' he recalled at a recent Startup Grind Muscat event, hosted by Walaa Hamdan. That revelation about Oman's marine life spurred deep research into climate science, eventually leading him to carbon capture—and more importantly, carbon storage, the Achilles' heel of many climate solutions. 'There was all this talk about capturing carbon, but no one was asking where to put it,' he explained. His answer? Mineralisation—a natural process that turns captured CO₂ into rock by injecting it into peridotite-rich formations, which are abundant in Oman. This process offered the promise of permanent, verifiable CO₂ removal. That idea crystallised into 44.01, named after the molecular weight of CO₂. Yet, moving from idea to implementation wasn't easy. Hasan left behind a prestigious, well-paid role in government—a 'very comfortable' position, he admitted—to found an unproven startup in a highly technical field. 'My own family thought I'd gone crazy,' he joked. 'But if you really believe in what you're doing... I just went for it.' The early days were lean and uncertain. "We didn't even know what kind of team we needed," he admitted. But he knew people were everything. Leveraging his network, he brought in a renowned carbon mineralisation scientist, a trusted colleague from IDO, and even interns from IDO programmes. Each person was chosen not just for technical skill, but for cultural fit. 'Spend time on culture,' he emphasised. 'Spend a lot of time on it.' At 44.01, team culture is intentional. They hold annual offsites, empower individuals to lead, and foster what Hasan calls a 'culture of thinking big.' As he put it, 'If you develop that culture of punching big, of being ambitious, and you get everyone in the team thinking like that, it starts to drive itself.' One of the company's first major hurdles was securing regulatory approval. 'Our first step was: Can we get the permit?' Hasan said. After months of pushing, they earned the world's first permit to mineralise CO₂ in this way—a milestone that validated their method and opened the door to commercial projects. Partnerships have been vital to scaling the vision. Early on, Hasan found himself navigating regulatory minefields, bringing six different government agencies to the same table—many of them meeting each other for the first time. 'If you can get more people to collaborate and get them in a room together, the sky's the limit,' he said. But partnerships aren't just about access or capital—they're about alignment. One potential lead investor dropped out of their Series A round for geopolitical reasons. Hasan later saw it as a blessing in disguise: 'Be picky about your investors,' he warned. 'Say no to money if the alignment isn't there. The wrong partners can pull you in the wrong direction.' That principled stance has paid off. 44.01 now boasts high-profile backers, including Sam Altman and Breakthrough Energy, the climate fund led by Bill Gates. The company has won the prestigious Earthshot Prize, along with multiple XPrize accolades—important endorsements, especially in a region more accustomed to importing rather than exporting advanced climate tech. Hasan remains clear-eyed about the stakes. 'If we can't do this in a way that's affordable, it won't scale,' he asserted. Economic viability is just as critical as environmental impact. To that end, 44.01 is now expanding into Europe, leveraging favourable regulatory frameworks and secured patents. Long term, the goal is to digitise the technology and license it globally, allowing others to deploy carbon mineralisation wherever the geology allows. As Hasan reflects on the journey from boardroom to bedrock, one message rings clear: 'Purpose comes before product.' For him, building 44.01 wasn't just about creating a business; it was about answering a personal calling to protect the planet—one mineralised tonne of CO₂ at a time.

OIA lauded for economic diplomacy via investments
MUSCAT: A new report by the SWF Global has commended the Oman Investment Authority (OIA) for strengthening Oman's global ties through targeted foreign investments, joint funds, and reinvesting divestment proceeds and returns into national projects. This approach sets OIA apart from its peers, as it adopts a unique philosophy centered on the 'Omani Angle' making it a foundational principle in its investment decision-making. SWF Global is a specialized organization focused on tracking activities of state-owned investment organizations, including sovereign wealth funds, central banks, and pension funds worldwide. The report highlighted OIA's success in building an extensive network of strategic relationships by promoting the concept of economic diplomacy with various countries across the Middle East, Asia, North Africa, Europe, and the Americas over the past five years. Among the most recent strategic partnerships is the signing of a joint fund agreement with Algeria worth $300 million, targeting investments in vital sectors such as mining, food security, and pharmaceuticals. Additionally, OIA partnered with Turkey's OYAK Fund to establish a joint investment fund valued at $500 million and launched a joint fund with Uzbekistan, which focuses on establishing a university in Tashkent in collaboration with Arizona State University of USA. Furthermore, OIA has invested in the Vietnam-Oman Investment Company, which has allocated nearly $400 million to projects in solar energy, infrastructure, healthcare, education, and food. The report also noted that OIA's focus is not limited to establishing strategic partnerships through joint investment funds alone, but also extends to direct investments in global companies, which primarily aim to localize advanced global technologies in the Sultanate of Oman, in addition to generating returns that are later reinvested into local projects. Notable examples include OIA's stake in Elon Musk's artificial intelligence firm 'xAI, in addition to 'Tidal Vision', a US-based company offering cutting-edge technological solutions to address pollution and climate-related challenges in the agriculture and water sectors. In the technology sector, OIA partnered with 'Golden Gate Ventures' of Singapore to establish a $100 million joint fund, leading to establish a local venture office in Muscat to manage joint investments between the two countries, and investing in local companies like 'Bayanat'. Collectively, these efforts underscores OIA's commitment to embedding the Omani angle across all its investments and partnerships. Moreover, the report highlighted OIA's policy to carry out strategic divestments from certain government assets, which contributed to revitalizing the Muscat Stock Exchange. Among the most notable of these divestments was the initial public offering (IPO) of 25% of 'OQ Exploration & Production' shares in October 2024, which marked the largest IPO in the history of the Sultanate of Oman. The offering aimed to strengthen foreign investor confidence in the Omani market while also involving citizens in the transformational shift of Oman's economy, in which OIA plays a central role. The report further noted that since mid-2022, OIA has successfully divested from 19 assets, generating returns exceeding RO 2.7 billion. These included public offerings such as 'The Pearl REIF', 'Abraj Energy Services' and 'OQ Gas Networks', all of which witnessed demand surpassing the supply. These IPOs are not only about generating financial returns; they are also intended to inject liquidity into Oman's financial markets, attract long-term foreign investment, and pave the way for future divestments. Locally, the report discussed OIA's efforts to strengthen its investments in the national economy through the National Development Fund (NDF), noting that total capital investment spending in local projects rose to RO 1.9 billion, surpassing the initial target of RO 1.7 billion. The report stated that the NDF represents 60% of the assets managed by OIA, and its investments are aimed at supporting the objectives of Oman Vision 2040. Additionally, OIA established Future Fund Oman (FFO) with a capital of RO 2 billion, of which 90% is allocated to large direct investments in viable local projects, and 10% to small, medium, and emerging enterprises- with the latter portion exceeding $519 million. The NDF focuses on sectors such as green energy, industry, and tourism to support the diversification of the Omani economy. FFO has witnessed strong interest in its first year, attracting investments worth more than US$ 2 billion, 70% of which came from foreign investors, across ten priority sectors, including artificial intelligence, fintech, clean energy, and ICT. This approach has distinguished OIA from its regional counterparts, where investment strategies are predominantly focused on the oil and real estate sectors.
