The main task of this module is to identify sustainable supply technologies in South Africa for energy supply of the cities and foster their application.
This overall objective can be concretised with the following tasks:
· To evaluate the economic and environmental performance of supply technologies and to apply pilot installations.
· To assess resources, current as well as future market development for supply technologies and energy sources.
· To compile this information into a “Technology Handbook”
· To contribute to the integrated assessment in module 1.
· To develop recommendations for sustainable supply technologies in South Africa.
The module is structured in 6 work packages as shown in the figure.
The aim of each work package is briefly explained below:
· WP1: Identifying the potentials of different energy sources and supply technologies.
· WP2: Evaluating the technical, economic and environmental aspects of available energy sources and supply technologies.
· WP3: Describing the technologic-economic perspectives of supply technologies for today and the future including cost-potential curves and cost-benefit assessment.
· WP4: Presenting, monitoring, evaluating and verifying the implementation of sustainable technologies on base of examples (see Module 7).
· WP5: Determination of opportunities and barriers in the South African energy market and among the stakeholders.
· WP6: Giving a summarised evaluation of supply technologies and recommendations for sustainable technologies.
Energy supply technologies that are investigated in Module 5 are grouped below:
1) Renewable Energies
• Solar technologies – SWH, PV, solar cooling, solar cooking, etc.
• Biomass: (fuel) wood, charcoal, algae (oil), maize and others
• Biofuels: bio-oil, biodiesel, bio-ethanol, bio-methane
• Residues and waste: biogas
• Geothermal Energy: heat pumps
2) Conventional and fossil based energies
• Electricity from conventional sources
• Cooking fuels: coal, paraffin, gas
• Synthetic fuels from coal, natural gas
3) New energy technologies
• Fuel cells
• Energy storage
• Others …
For each group the following technology aspects will be considered particularly:
· power plants – generators - CHCP systems
· grid based - off-grid technologies
· individual - community based
· Supply and distribution systems, incl. storage
