Zinc batteries with double efficiency and the ability to produce hydrogen

The renewable energy revolution wants to build a climate-friendly future for the world. But the move away from fossil fuels will remain a challenge as long as efficient means to store green energy are still lacking. A research consortium has set itself the goal to tackle exactly this problem with cheap-to-make zinc batteries that not only store electrical power, but can also be used to produce hydrogen.

A proposal to build a sub-Saharan Africa electrical grid across 12 countries

A team of economists and engineers from China, Turkey and Nigeria has published a proposal based on simulations to build a sub-Saharan Africa electrical grid across 12 countries. In their paper published in the journal Scientific Reports, the group outlines which countries would be involved, factors that would be used to build such a grid, and estimated costs.
