Globally, air pollution from cooking using fuelwood, coal and dung contributes to over , including .
In Zambia, having electricity at home does not automatically lead to cleaner cooking. In the global south, electricity only starts to support clean cooking once . In Zambia, of people have access to electricity. and high residential tariffs make cooking with electricity either unreliable or unaffordable.
We are renewable energy and green hydrogen researchers who set out to discover the potential for the use of green hydrogen as an alternative source of power. is produced from water and renewable electricity. It’s a clean, storable fuel that can be used like fossil gas, without the emissions. It could offer households a flexible, low-carbon substitute for charcoal or liquefied petroleum gas.
was based on a modelling exercise that looked at various factors related to green hydrogen and the situation in Zambia.
The renewable energy used to make green hydrogen usually comes from a solar or wind power system set up especially for the green hydrogen plant. For instance, the plans to use solar and wind power to produce green hydrogen for export and domestic use.
These systems are expensive to build and operate. They also require significant upfront capital and storage infrastructure to ensure reliable output.
used a computer simulation model to study the costs of green hydrogen plants, the amount of revenue they could generate, their technical performance, and their reliability. We also estimated the value that each unit of green hydrogen would bring to society through providing clean cooking energy.
