Experts say that hydrogen is one answer to South Africa’s greenhouse gas emissions problem.
Hydrogen is a fuel source that is a possible alternative to fossil fuels. It can be used in fuel cells and to create heat, and its only by-product is water, meaning it does not release any greenhouse gases when burned.
Carbon dioxide is a chemical compound that presents as a gas in the Earth’s atmosphere. It consists of one carbon atom and two oxygen atoms.
Greenhouse gases are gases that trap heat in the atmosphere. This can be any gas that absorbs infrared radiation and contributes to the Earth’s warming or the greenhouse effect.
Since 2006, the amount of gas in the atmosphere has increased, according to NASA. The oil and gas industry has caused the majority of methane gas emissions since 2006, NASA says.
Biogas is a renewable energy source produced when anaerobic bacteria break down organic materials. It is different from natural gas as natural gas is a fossil fuel, while biogas is a renewable energy source.
In August 2021, South Africa’s National Business Initiative (NBI) published a government-backed report. It described the pathways that the country must take to decarbonise.
Currently, South Africa is neither a large exporter nor importer of LNG. However, there are now plans in the country to develop this fossil fuel industry.
