Renewable and alternative energy

It is vital for any enterprise, let alone agricultural ones, to have a steady, reliable and cost-effective source of energy. The power constraints in South Africa mean that surely we should be looking at all our options now! There is no way that Eskom alone can fund and deliver energy enough to meet the country’s generation, transmission and distribution infrastructure needs to 2030 (Creamer, 2019). A greater diversity of energy resources is in the best interests of national and international security.

Renewable energy resources have a security of supply, being continually replenished. Start-up costs are increasingly affordable, and as tariffs increase the lower the break-even point (the time the system takes to pay for itself) becomes (Lemmer & Schmidt, 2019). After this, energy is sourced from the sun, wind, water or other natural/organic matter, and done so without pollution (why we call renewable energy technologies “clean technologies”).

The renewable energy sector is currently four times more employment-intensive than SA coal and nuclear (SAWEA, 2019). It is the fastest growing energy sector in the world (Unwin, 2019). For South Africa, renewable energy could mean job creation, sustainable development, and a reduced burden on Eskom. It is also a sane, logical response to global warming.

Biogas

Visit http://biogasassociation.co.za.

What is biogas ?

A biogas digester (also known as a biogas plant), comprises a large tank in which biogas is produced through the decomposition/breakdown of organic matter (Such as food waste and plant matter) through a process called anaerobic digestion. It’s called a digester because organic material is eaten and digested by bacteria to produce biogas.

Biogas is a mixture of carbon dioxide and methane, that resembles liquid petroleum gas. Like natural gas, biogas is used as a fuel to produce electricity, to power farm equipment, for lighting applications, in gas cookers for cooking, and even as fuel for vehicles. Biogas is widely used across the world.

How does a biogas digester work?

A typical biogas digester has a container that holds organic matter and water, called slurry. A digester also has second container that holds the gas that has been produced after the organic matter is broken down. A series of pipes connect the slurry into the digester and from there connect to the container that will hold the gas output. There is also a transport system to take the biogas to where it will be used. The digester also has a mechanism for ejecting the residue.

Biomass

Biomass is a term generally referring to any plant or animal matter. Examples of biomass as a direct fuel source include wood, animal manure, sugar cane residue and agricultural wastes, particularly in rural areas.

Energy can also be produced by converting biomass to a gas. Plant oils are also produced from biomass. These oils can be extracted from sunflowers, soybeans, groundnuts, vegetables and other plants, and turned into fuel.

Biogas is dealt with under the previous heading. For notes on biofuels (ethanolo and biodiesel), please consult the separate “Biofuels” chapter.

Geothermal energy

This is energy contained in the heated rock and fluid that rises from the extremely hot core of the Earth and filters into cracks and pores in the Earth’s crust. It can exist as hot water, steam or hot dry rocks. In order to access it, wells are drilled into the Earth’s surface. South Africa does not have many geothermal resources, except in the area around Aliwal North and in the Cape Fold mountains.

Hydro energy

Energy in water, in the form of motive energy or temperature differences, can be harnessed and used. Since water is about a thousand times heavier than air, even a slow-flowing stream of water can yield great amounts of energy.

Hydroelectricity, a renewable energy source obtained from moving water, supplies about 20% of the world’s electricity. With seven major rivers (Nile, Niger, Congo, Senegal, Orange, Limpopo and Zambezi) Africa, which holds about 10 percent of the world hydro-energy potential and, with very low energy per capita consumption level, has so far exploited a small part of its capability.

There is a high capital cost, and social and environmental impact to large dams. Because of this, renewable hydro developments today are increasingly focused on smaller-scale projects (less than 10MW). These smaller hydro-plants do not impact on riverine eco-systems, and using local technology and skills to develop small-scale hydro can also create local jobs.

Hydroelectricity can also be generated from the ocean (marine energy or marine power).

Solar

One hour of sunlight packs enough energy to power the world for a day.

An area of 70km x 70 km could provide all of South Africa’s electricity requirements from concentrated solar power (CSP)

Solar resources are by far the most abundant and readily accessible in South Africa, as Africa is well endowed with sunshine the whole year round. We have twice as much sunlight than that in Europe where solar power units are compulsory in some countries such as Switzerland. In Europe you find solar power “farms” where farmers make more money from selling surplus solar power to the national grid than from traditional farming.

There are two distinct ways we can utilise solar power, either by using the heat of the sun (solar thermal) or by converting sunlight into electricity with photovoltaic panels. There is also “passive solar” – buildings are constructed in such a way that they absorb the heat of the sun (by facing north) thereby reducing heating costs.

Solar power for farms in remote regions is a viable option because they may not have direct access to grid-fed electricity.

Waste to energy/landfill gas

Also see the “Waste management” chapter.

Landfill gas is a complex mix of different gases created by the action of micro-organisms within a landfill. These gases can be collected and used to produce heat or electricity. Not only are landfill gas projects an important source of energy (what a creative form of waste management!), they also reduce greenhouse gas emissions.

Wind energy

An example of wind energy with which everyone is familiar is the good old windmill (also in a separate chapter). But let’s move on…

South Africa, with its ample coastline, has the potential for major electricity generation from wind. Indeed, wind contributes 52% of South Africa’s renewable energy power, with more than 900 wind turbines spread over three provinces (SAWEA, 2019).

The 7th of the Sustainable Development Goals (SDGs) is “affordable and clean energy”. See www.un.org/sustainabledevelopment.

According to BP’s 2019 “Energy Outlook”, renewable energy accounted for 8.5% of the world’s power generation in 2017 and could rise to 29% by 2040. Europe is the leader in renewable energy power generation, with 21.7% of its energy coming from renewables, and could be at 53.4% by 2040 (Unwin, 2019).

Local business environment

To date (March 2019), 3 776 MW of electricity generation capacity from 62 IPP projects has been connected to the national grid.

In just 8 years (including a 3-year period where no new procurement was undertaken), government’s Renewable Energy Independent Power Producer Procurement Programme (REIPPP) has attracted R209.4 billion in committed private sector investment (SAWEA, 2019).

Local communities have already benefited from over R1 billion spent by IPPs on education such as upskilling of teachers, extra teachers and classrooms, and 600 bursaries to students from disadvantaged communities, the provision of health facilities and medical staff, social welfare such as feeding schemes, support to old age homes and early childhood development and support to and establishment of more than a 1 000 small enterprises.

The South African renewable energy sector has created 38 701 Full Time Equivalent (FTE) person-years of employment for youth, woman and citizens from the surrounding communities. The sector is currently four times more employment-intensive than SA coal and nuclear.

Source: https://sawea.org.za/stats-and-facts-sawea/

The motivation to become less reliant on the national energy grid are several:

• Improved regulatory support for alternative sources
• Increased electricity tariffs
• Awareness and acceptance of renewable energy technologies
• Decreasing costs of the hardware and installation
• South Africa’s ready supply of renewable resources for energy production
• An increasingly unreliable supply of power from the national utility.

South Africa has reached the tipping point in moving from dependence on fossil-based energy to renewable energy, and this trend will escalate further in the near future.

National strategy and government contact

Find the government/parastatal role players under the next heading.

Renewable energy generation is seen as a possible catalyst for increased economic benefits and industrial development by achieving various objectives in South Africa:

• job creation
• improved export competitiveness
• assisting South Africa to reach its carbon mitigation commitments
• safeguard exports from possible carbon tariffs and taxes and
• build energy security

Renewable energy plays a vital role in assisting South Africa to reach its commitment to reduce greenhouse gas emissions with the potential of creating employment opportunities and generating green investment.

The Integrated Resource Plan 2019 (IRP 2019) contains proposed allocations to renewable energy. Find it at www.energy.gov.za.

Small-scale embedded generators (SSEGs) or installations generating less than 1MW do not require a generation licence. SSEGs or farmers producing electricity via a renewable source must register with NERSA and Eskom. A business installing an SSEG can write off 100% of its investment in the first year.
