    • Coal: 60%

    • Renewables & Waste: 19%

    • Crude oil: 15%

    • Petroleum Products: 2%

    • Nuclear: 2%

    • Gas: 1%

Natural Gas Policy Questions

  1. Just Energy Transition:

    • Debate: Does RSA need natural gas for its Just Energy Transition or can renewables suffice?

  2. Gas Utilization Master Plan (GUMP):

    • Indicates ongoing revisions to policy to adapt gas strategies in RSA.

Global Natural Gas Demand

  • Wood Mackenzie Projections:

    • Global primary energy demand by source shows a steady increase in natural gas consumption projected up to 2048.

  • Shift from Oil to Gas: Natural gas is now considered more resilient than oil due to its supportive role in electricity generation and its compatibility with renewable energy growth.

Challenges Facing Natural Gas in RSA

  • Gas Cliff:

    • Declining natural gas supply anticipated from Mozambican fields could lead to significant job losses and energy shortages.

    • -

  • Growing Demand Challenges:

    • Limited local supply and lack of infrastructure hinder industry growth.

    • Stranded assets risk if current supply issues are not addressed.

Future Gas Supply & Infrastructure

  • Potential Sources for RSA's Gas Supply:

    1. Karoo: Hydraulic fracturing presents environmental concerns.

    2. Southern Coast: New offshore gas finds require analysis of infrastructure and market access.

    3. Namibia and Mozambique: Potential LNG imports but limited by market logistics and political factors.

  • LNG Infrastructure Needs:

    • Floating Storage and Regasification Units (FSRUs) as potential solutions for rapid LNG import capacities.

Regulation of Natural Gas in RSA

  • Nersa's Role: NERSA (National Energy Regulator of South Africa) regulates maximum gas prices where competition is inadequate.

  • Gas Pricing Models: Requires balancing supply and demand while attracting investments for infrastructure.

  • Policy Uncertainty: Lack of coherent energy and gas policy complicates the regulatory environment.

Liquefied Petroleum Gas (LPG) Overview

  • Differences from Natural Gas:

    • LPG is produced from both natural gas processing and oil refining and has distinct regulatory and market dynamics.

  • Storage and Pricing Challenges: LPG has faced notable shortages and is regulated differently with maximum price methodologies determined by local costs and import parity.

Summary of Natural Gas and LPG Regulatory Framework

  • Regulatory Bodies: Multiple regulators including NERSA oversee different aspects of LPG and natural gas supply chains, raising questions of efficiency and enforcement.

  • Future of Gas in SA:

    • The energy transition necessitates clear policies to ensure a reliable and cost-effective gas supply, while addressing environmental and sustainability goals.

Natural gas is primarily composed of methane (CH₄) and is used as a critical energy source across various sectors, including electricity generation, heating, and as a fuel for vehicles. It is considered more environmentally friendly compared to other fossil fuels like coal and oil because its combustion releases significantly lower amounts of carbon dioxide and other pollutants. Natural gas plays a significant role in the global energy system as a bridge fuel in energy transitions, aiding the move towards more sustainable energy practices while supporting existing infrastructures.

Current Energy Landscape

RSA Primary Energy Sources (2020):

  • Coal: 60%

  • Renewables & Waste: 19%

  • Crude oil: 15%

  • Petroleum Products: 2%

  • Nuclear: 2%

  • Gas: 1%

While South Africa has a high reliance on coal, there is an increasing push towards diversifying the energy mix with renewables and a more significant role for natural gas.

Natural Gas Policy Questions

  1. Just Energy Transition:

    • Debate: There is an ongoing debate about whether South Africa needs natural gas for its Just Energy Transition or if renewables alone can suffice. Proponents of natural gas argue that it can serve as a transitional fuel that stabilizes electricity supply while renewables are scaled up.

  2. Gas Utilization Master Plan (GUMP):

    • This plan indicates ongoing revisions to policies aimed at adapting gas strategies in South Africa, including investments in infrastructure to enhance gas supply chain efficiency.

Global Natural Gas Demand

Wood Mackenzie Projections:

  • Global primary energy demand projections indicate a steady increase in natural gas consumption, which is expected to continue up to 2048.

  • The shift from oil to gas is significant, as natural gas is viewed as a more resilient energy source due to its supportive role in electricity generation and its compatibility with renewable energy growth.

Challenges Facing Natural Gas in RSA

  1. Gas Cliff:

    • A decline in natural gas supply is anticipated from Mozambican fields, which could lead to significant job losses and energy shortages in South Africa. This scenario raises concerns about energy security and economic stability.

  2. Growing Demand Challenges:

    • Limited local supply and a lack of infrastructure are major hurdles that hinder the growth of the natural gas industry.

    • There is a risk of stranded assets if current supply issues are not addressed, especially as investments in gas infrastructure may become unviable.

Future Gas Supply & Infrastructure

  1. Potential Sources for RSA's Gas Supply:

    • Karoo: There is potential for hydraulic fracturing (fracking), which raises environmental concerns and public resistance.

    • Southern Coast: New offshore gas finds are emerging, requiring thorough analysis of the necessary infrastructure and market access for effective distribution.

    • Namibia and Mozambique: Potential for Liquefied Natural Gas (LNG) imports exists, though this is limited by market logistics and political factors.

  2. LNG Infrastructure Needs:

    • Floating Storage and Regasification Units (FSRUs) are being considered as potential solutions for rapidly expanding LNG import capacities, crucial for meeting future demand.

Regulation of Natural Gas in RSA

  1. Nersa's Role:

    • The National Energy Regulator of South Africa (NERSA) regulates maximum gas prices where competition is inadequate, ensuring consumer protection while fostering market development.

  2. Gas Pricing Models:

    • Models must effectively balance supply and demand to attract investments necessary for infrastructure development.

  3. Policy Uncertainty:

    • The lack of coherent energy and gas policy complicates the regulatory environment, making long-term planning and investment more challenging for stakeholders in the natural gas sector.

Liquefied Petroleum Gas (LPG) Overview

  1. Differences from Natural Gas:

    • LPG is produced both from natural gas processing and oil refining, leading to distinct regulatory and market dynamics that differentiate it from natural gas, particularly in usage, pricing and distribution strategies.

  2. Storage and Pricing Challenges:

    • LPG has faced notable shortages, and its pricing is regulated differently, with methodologies that determine maximum prices based on local costs and import parity principles.

Summary of Natural Gas and LPG Regulatory Framework

  1. Regulatory Bodies:

    • Multiple regulators, including NERSA, oversee various aspects of LPG and natural gas supply chains, raising concerns about efficiency and enforcement capabilities across the regulatory spectrum.

  2. Future of Gas in SA:

    • The energy transition necessitates clear, coherent policies to ensure a reliable and cost-effective gas supply while addressing broader environmental and sustainability goals, essential for long-term economic viability and energy security in South Africa.
