The restructuring of energy use, including the development of renewable energy, is clearly important and frequently appears in global headlines. But while renewable energy is growing in importance, its storage is comparably less discussed.
The storage of renewables is more difficult than that of traditional energy because the generation of renewable energy tends to be unstable during a given time span, said Bastian Mingers, executive team manager of Energy Storage Europe at Messer Dusseldorf in Beijing on May 10.
"Renewables are a major issue for energy storage solutions. Take PV energy and wind power for example, which are going up and down. You can't estimate when you will need the power, so have to store the energy they generate," said Mingers.
He explained that the generation of PV energy and wind power is heavily affected by weather. In ideal conditions, the sudden surges will upset the power grid. Therefore, to store the energy by a capacitator will be necessary to "smooth the electric current."
Mingers compared new-type of energy storages to a Swiss army knife, since the latest energy storage products "can do more than just store energy" and are "more than just a battery."
Mingers admit that Chinese users in both the industrial and residential sectors are only beginning to understand the importance of power storage and how much difference a proper power storage product or solution will make on their electricity bills.
Messer Dusseldorf was a co-organizer of the 5th International Conference and Expo on Energy Storage and Microgrids in China, which was held from May 10-12. Messe Dusseldorf holds annual meetings on energy storage in San Diego, Mumbai and New Delhi, as well as its home turf of Dusseldorf.
