We are betting the bank on hydrogen. But are we ready for it?

Green hydrogen holds many promises: it can serve as a "battery" for energy storage, it can be used in the chemical industry, and its only emission will be water vapor. But, unfortunately, green hydrogen is not yet widely ...

Cooking with solar ovens in sub-Saharan Africa

Although sub-Saharan areas may seem perfect for solar ovens, many people use wood or coal as the main source of energy for cooking, especially in areas that are not connected to the power grid.

Energy storage

Energy storage media are matter that store some form of energy that can be drawn upon at a later time to perform some useful operation. A device that stores energy is sometimes called an accumulator. All forms of energy are either potential energy (eg. chemical, gravitational or electrical energy) or kinetic energy (eg. thermal energy). A wind up clock stores potential energy (in this case mechanical, in the spring tension), a battery stores readily convertible chemical energy to keep a clock chip in a computer running (electrically) even when the computer is turned off, and a hydroelectric dam stores power in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy)at night to meet peak demand for cooling . Even food is a form of energy storage, chemical in this case.
