Unleashing the potential of green hydrogen in SA Mareli Botha, technical director at Zutari, talks about green hydrogen as a ‘beacon of hope’ for the sustainable energy transformation, particularly in South Africa.

converged to propel it into the spotlight. The plummeting costs of renewable energy, ad vancements in fuel cell technology, a thriving green product market, and a deeper under standing of hydrogen's applications have all contributed to this resurgence. But how does green hydrogen fit into South Africa’s energy landscape? At Zutari, we recognise that the value chain of green hydrogen encompasses various specialised domains. From sourcing renewable energy to water procurement and purification for electrolysis, each step requires expertise and strategic integration. Our capabilities span these domains, offering tailored solutions to clients navigating the complexities of green hydrogen projects. In South Africa, where the focus has pre dominantly been on solar and wind energy, green hydrogen presents a new frontier. While short-term applications may seem limited due to cost considerations, there is growing interest in sectors such as mining, where the reliability and stability of hydrogen outweigh immediate economic concerns. Looking ahead, green hydrogen holds immense promise for sectors beyond energy

storage. Industries such as steel production and chemical manufacturing stand to benefit, tapping into burgeoning international markets for green products. However, there is an ethi cal imperative to ensure local benefits amidst global exports. South Africa must navigate this balance, leveraging its natural resources, while fostering a sustainable economic ecosystem. At Zutari, we envision a future where green hydrogen drives economic growth, creates jobs and positions South Africa as a global leader in sustainable innovation. Yet, achiev ing this vision requires concerted efforts to address regulatory, financial and infrastruc tural challenges. It is a journey fraught with complexities, but one brimming with oppor tunities for meaningful change. Green hydrogen is not just a buzzword; it is a catalyst for transformation. As we chart the course towards a greener, more sustainable future, let us seize the potential of green hy drogen to power progress, locally and globally. Together, we can build a brighter tomorrow fuelled by innovation, collaboration, and a steadfast commitment to sustainability. www.zutari.com

A mid global conversations about sustainable energy solutions, one term has emerged as a beacon of hope: green hydrogen. But what sets today’s discourse apart from the excite ment of two decades past? With a keen eye on the intricate dynamics of energy systems, I will explore this question and shed light on the transformative potential of green hydro gen, particularly within the unique context of South Africa. First, let us demystify hydrogen itself. It is a lightweight gas that serves as an energy carrier, boasting high energy content per unit mass. However, its energy density per volume is low compared to traditional fuels such gaso line. Crucially, hydrogen is not a primary fuel; it must be produced using energy, with green hydrogen specifically relying on renewable sources. So, why is there a buzz around green hydrogen at present? Several factors have

Hydrogen must be produced using energy, with green hydrogen specifically relying on renewable energy sources.
