Think of solar panels more like apple trees: We need a fairer approach for what we use and sell, says researcher

Garde01 mins
As we race to decarbonize by electrifying everything, solar panels—now cheaper per square meter than marine-grade plywood—will do much of the heavy lifting. But if we don’t rethink how our rooftop panels plug into the grid, the transition will be unfair and costly—for both people who own solar panels (and electric cars and smart appliances) and people who don’t.

Rolling blackouts are costing South Africa dearly. The electricity crisis is a barrier to growth, destroys investor confidence and handicaps almost every economic activity. It has raised input costs for producers and retailers, and has triggered a new round of inflation and interest rate increases.

Developing technologies to reduce the cost of green hydrogen production

Garde01 mins
Green hydrogen, which produces hydrogen without the use of fossil fuels or the emission of carbon dioxide, has become increasingly important in recent years as part of efforts to realize a decarbonized economy. However, due to the high production cost of water electrolysis devices that produce green hydrogen, the economic feasibility of green hydrogen has not been very high. However, the development of a technology that drastically reduces the amount of rare metals such as iridium and platinum used in polymer electrolyte membrane water electrolysis devices is opening the way to lower production costs.
