The International Air Transport Association (IATA) called on South Africa to mobilise its experience, resources, and infrastructure to accelerate the development of Sustainable Aviation Fuel (SAF) production. The call came as government and industry officials gathered in Johannesburg for the IATA Wings of Change Focus Africa conference.

“South Africa has vast potential to become a leading Sustainable Aviation Fuel (SAF) producer in the region. And there is a waiting market for SAF as airlines work to achieve net zero carbon emissions by 2050. More than a strategy in support of aviation’s decarbonisation, it is a strategy for economic development and should be a top priority for the new South African government. Across agriculture, energy, and transportation, new jobs and industries are waiting to be created that would not only help fight poverty but also contribute to greater energy independence,” said Marie Owens Thomsen, IATA’s senior vice president for sustainability and chief economist.

Growth in Africa and across the world

South Africa chaired the 2022 ICAO Assembly at which governments agreed to a long-term goal aligned with the aviation industry’s net-zero carbon emissions by 2050 commitment. The role of SAF in achieving this goal was emphasised by the ICAO CAAF/3 objective of a 5% average global reduction in aviation’s carbon emissions by 2030. As decarbonising aviation will require global collaboration, it is critical that global or regional stakeholders like States, development banks, industry, academia and other relevant parties bring forces together to help countries with SAF potential to develop their industry.

“Airlines are ready and waiting to purchase SAF as evidenced by the fact that every drop of SAF produced has been purchased and used. But the production volumes are a minute fraction of what aviation needs. That’s why it is essential for governments of countries with production potential, such as South Africa, to embrace what is a unique win-win-win opportunity for economic development, energy transition, and decarbonised air transportation,” said Thomsen.

Synergy Consulting discusses the advantages and challenges of e-fuels, and how a favourable environment can be created for their growth

E-fuels, or electro fuels, are synthetic fuels produced using electrolytic hydrogen. They are considered low-emission fuels when both their hydrogen and carbon inputs are derived using methods that result in minimal life-cycle greenhouse gas emissions. The production of e-fuels involves combining hydrogen with other elements to create different types of fuel products, each with specific applications and infrastructure requirements. Various different fuel types can be produced along this basic route.

Different fuel products can be further categorised by their ease of use. Drop-in e-fuels such as e-kerosene, e-diesel and e-gasoline are compatible with existing refuelling infrastructure and can be blended with limited constraints with petroleum-derived counterparts. By contrast, alternative e-fuels such as e-ammonia and e-methanol require investments in distribution infrastructure and end-use equipment to enable their use in the transport sector.

These types of fuels present yet another avenue in our quest towards a cleaner future by reducing greenhouse gas emissions in the energy and transportation sectors given that they utilise renewable electricity for their production. Drop-in e-fuels offer an easier transition due to their compatibility with existing infrastructure, whereas alternative e-fuels, despite their potential, require significant upfront investments.

E-fuels offer significant advantages in terms of reducing greenhouse gas emissions and utilising existing infrastructure, but they also face substantial challenges, particularly related to production costs, energy efficiency, and the need for substantial investments in new infrastructure. Balancing these factors is essential for the successful development and deployment of e-fuels.

Reduction in greenhouse gas emissions: E-fuels can significantly lower life-cycle greenhouse gas emissions when produced using renewable energy sources and sustainable carbon capture methods
Compatibility with existing infrastructure: e-fuels like e-diesel, e-gasoline, and e-kerosene can be used with existing refueling and distribution infrastructure, reducing the need for significant changes or new investments
Energy storage and transport: can store energy from intermittent renewable sources (like wind and solar) in a stable, transportable form, addressing the challenge of renewable energy storage
Energy security: By producing these fuels domestically, countries can reduce their dependence on imported fossil fuels, enhancing energy security

However, there still exist significant challenges in a greater adoption of such fuels. The current cost of producing e-fuels is relatively high compared to conventional fossil fuels due to the energy-intensive nature of the processes involved and the need for advanced technologies.

The overall energy efficiency of e-fuel production can be low, as significant energy is required for electrolysis and subsequent synthesis processes, leading to higher overall energy consumption.

In addition, alternative e-fuels such as e-ammonia and e-methanol require new investments in distribution and refuelling infrastructure, as well as modifications to end-use equipment, posing a financial challenge. Many technologies related to e-fuel production are still in the development or early commercialisation stages, requiring further research, development, and scaling up to become viable.

Given these challenges, accelerated deployment of e-fuels thus requires a comprehensive approach that includes policy support, infrastructure investment, cost reduction of key technologies, R&D promotion, and exploitation of synergies with other sustainable technologies.

Integrating e-fuels with biofuels and carbon capture utilisation and storage (CCUS) can lead to maximising benefits.

By addressing these areas, host countries and governments can create a favourable environment for the growth of the e-fuel industry, driving down costs and making e-fuels a viable alternative to conventional fossil fuels.

The International Renewable Energy Agency (IRENA) has formed a significant partnership with Africa50, a leading pan-African infrastructure investment and asset management firm

As part of this agreement, Africa50 has committed up to US$100mn to support and co-finance renewable energy transition projects and infrastructure across Africa through IRENA’s Energy Transition Accelerator Financing (ETAF) platform. This partnership aims to enhance sustainable development and advance climate action initiatives throughout the continent.

The agreement was signed on the margins of the OPEC Fund Development Forum in Vienna by IRENA director-general, Francesco La Camera and Africa50 CEO, Alain Ebobissé.

"For the first time in a decade, the most recent data show that the number of people without access to electricity has increased significantly," said La Camera. "With Sub-Saharan Africa representing the majority of those impacted, we must be diligent and committed to urgently addressing this growing issue. Renewables represent the most effective, climate-safe solution available, and this partnership with Africa50 will be pivotal in strengthening the ETAF Platform’s impact across Africa."

Alain Ebobissé, CEO of Africa50 said, “The continent must focus on the dual goals of reducing emissions and accelerating economic development. Investing in and developing transformational renewable infrastructure is a critical step to achieving net-zero. The IRENA ETAF platform will be an important launchpad to scaling and accelerating our investments into renewable projects that will ultimately reduce the negative impact of climate change on our people and help build a more sustainable future”.

Established in 2021 with backing from the United Arab Emirates, the Energy Transition Accelerator Financing (ETAF) platform aims to scale up renewable energy projects that align with developing countries' Nationally Determined Contributions (NDCs). It seeks to enhance energy access and security for communities, promote economic growth, and foster diversification.

Africa50's recent involvement has expanded the ETAF Platform to include 14 partners, collectively pledging US$4.15bn. This growth underscores its status as a leading inclusive financing platform for transitioning to renewable energy. The partnership capitalises on IRENA's global membership to attract project proposals through the ETAF Platform and Africa50's expertise in project development and equity financing.

Hewlett Packard Enterprise and Danfoss are collaborating to deliver the HPE IT Sustainability Services – Data Centre Heat Recovery, an off-the shelf heat recovery module, helping organisations manage and value excess heat as they transition towards more sustainable IT facilities.

The rapid integration of AI technologies across organisations and businesses is expected to have a dramatic increase in the power demand and utilisation of AI optimised IT infrastructure.

According to the International Energy Agency, by 2026 the AI industry is expected to have grown exponentially to consume at least ten times its electricity demand in 2023. To mitigate these challenges, IT leaders and data centre facility operators are taking action to reduce energy usage, such as implementing modern power-efficient capabilities and improved cooling systems.

Excess heat in the EU alone represents an estimated 2,860 TWh/y, almost equal to the EU’s total energy demand for heat and hot water in residential and service sector buildings. The flow of excess heat from data centres is uninterruptible and therefore constitutes a very reliable source of clean energy.

“Our strategic partnership with HPE is a great example of how we revolutionise building and decarbonising the data centre industry together with customers,” said Jürgen Fischer, president, Danfoss Climate Solutions. “With this latest cross-industry partnership we’re building the blueprint for the next generation of sustainable data centres – using technologies available today”.

“The Data Center industry is booming in MENA, and at Danfoss we are committed to providing solutions to reduce their carbon footprint and enhance energy efficiency. This is one of the excellent initiatives taken, where we lead the way in providing the industry with the right know-how and paving the way to greener data centres”, added Ziad Al Bawaliz, regional president at Danfoss Turkey, Middle East and Africa.

Modularity's advantages and flexibility

Direct liquid cooling (DLC) technologies are included into HPE's MDC to optimise energy production and distribution and increase energy efficiency by more than 20%, resulting in significant energy savings.

The compact design maximises the temperature differential between the input and exit, which encourages the capture of excess heat, and minimises energy loss by shortening the distance for the transmission of energy and cooling fluid. Additionally, the MDC's flexibility and the removal of heavy industrial components significantly shorten the time to market by eliminating the requirement for pricey, traditional building materials.

Three times as fast as with typical data centres, deployment can be completed in as little as six months, as opposed to eighteen.

Last but not least, the MDCs' smaller footprint and adaptability enable their placement close to data creation locations, which lessens the energy impact and bottlenecks related to sophisticated networking solutions and data transfer while simultaneously promoting improved data governance and security.

“At HPE, we believe in the power of collaboration to create transformative solutions,” said Sue Preston, vice president and general manager, WW Advisory & Professional Services & Managed Services, HPE. “Our partnership with Danfoss brings together HPE’s innovative modular data centre with Danfoss’ groundbreaking heat reuse technology. Together, we are not just adding value; we are multiplying it. By harnessing the typically untapped resource of waste heat, turning waste into worth, showing the future of energy usage is efficient, intelligent, and, most importantly, achievable now.”
