Concentrated sunlight used to produce hydrogen

Researchers at the Swiss École polytechnique fédérale de Lausanne (Lausanne Federal Institute of Technology, or EPFL) created a device that uses a smaller amount of rare and costly materials required to produce hydrogen by concentrating sunlight to maintain a high solar-to-fuel efficiency. “Hydrogen will play a key role in reducing our dependence on fossil fuels. It can be sustainably produced using solar energy to split water molecules. The resulting clean energy can be stored, used to fuel cars or converted into electricity on demand,” says the research team at the EPFL Laboratory of Renewable Energy Science and Engineering (LRESE).

SA urged to home in on green-hydrogen export niche

The technology to produce green hydrogen, which is produced by electrolysing water using renewable energy, in South Africa is becoming cost-effective enough to develop the capacity to sell the product in local and international industrial markets, says technical advisory services firm Kambuku Consulting founding director Justin Wimbush. The available technology is viable for South African-produced green hydrogen to be supplied to the European transport markets. This is supported by the fact that countries, such as Japan, are putting in place arrangements to buy hydrogen generated in locations as distant as Chile, he highlights.
