The Cabo Delgado province in the northernmost part of the long Mozambican seaboard is now home to Africa’s three largest liquefied natural gas (LNG) projects; these projects have attracted many of the world’s major multinational energy companies, accompanied by massive LNG investments. There can be little doubt that the discovery of rich LNG reserves is a potential game changer for Mozambique’s economy and the development agenda of the country. It is potentially an opportunity for the rapid advancement of a country that currently ranks close to the bottom of the United Nation’s Human Development Index. World Bank data annually ranks Mozambique as among the poorest countries in the world.

Mozambique ‘has hit the jackpot’

Since 2011, rich LNG reserves have been discovered off the coast of Cabo Delgado in the Rovuma Basin. With the discovery of major offshore gas fields, many observers have been prompted to suggest that Mozambique, one of the poorest countries in the world, ‘has hit the jackpot’ – and recently, it has been claimed that by the mid-2020s, Mozambique could become one of the top ten LNG producers globally. Together, the gas projects are estimated to be worth $60 billion, and this could obviously revolutionise Mozambique’s economy of $15 billion.

However, despite the billions in investments by major multinational energy companies since 2012, the people of Cabo Delgado are yet to see the material benefits from these projects. One of the biggest risks for international investors in the LNG industry is the many unknowns associated with the threat posed by the militant Islamic movement, Ansar al-Sunna, which has especially been active in the Cabo Delgado province since 2017. Whereas Ansar al-Sunna, locally known as Al-Shabaab, initially advocated the ‘purification’ of Islam in Mozambique by preaching a moving away from the practices of the mystical traditions of Muslim Sufis – who are the majority of Muslims in Mozambique – and projecting Sufis as degenerate, the movement eventually made it clear that its goal was to impose Sharia law (Islamic law) in Cabo Delgado.

Since independence in 1994, the central government of Maputo has lacked a monopoly over the means of violence in its territory and its long coastline. In this context, Renamo regularly clashed with the central government in a 16-year civil war that claimed more than a million lives. Fast forward to the future – Ansar al-Sunna with its ISIS links now poses the main security threat to the Mozambican government and its armed forces.

The situation has gone from bad to worse

The escalation of violence and armed conflict since early 2020 has raised some pressing questions over the future of LNG investments, and even put the future of the LNG industry at high risk. Obviously, the foreign companies with their substantial investments feel threatened, especially at the current stage where final investment decisions have to be taken.

In recent months, the situation in Cabo Delgado has gone from bad to worse. In November 2020, dozens of people were reportedly beheaded by Islamic militants in northern Mozambique. Now the beheadings and bloodshed have spread to the town of Palma; taking the bloodshed to another level. This is not good news for the LNG industry in Mozambique, as Palma is supposed to become the manufacturing hub where hundreds of skilled workers will be located.

Amid the development of an increasingly alarming human rights situation towards the end of last year, including the killing of civilians by insurgents, the United Nations High Commissioner for Human Rights, Michelle Bachelet, has appealed for urgent measures to protect civilians in what she described as a “desperate” situation and one of “grave human rights abuses”. She also stated that more than 350 000 people have been displaced since 2018.

In conclusion, there is little doubt that Islamist insurgents have managed to increase the scale of their activities in Cabo Delgado, and that the lack of governance and a proper security response by both the Mozambican government and Southern African leaders make this a case of high political risk, which can potentially jeopardise the successful unlocking of the country’s resource wealth. Until now, the main LNG installations and sites have not been targeted or directly affected, but the security risks to these vast investments – and Mozambique’s development potential – are certainly on the increase and posing a threat to the LNG industry.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
