Vårgårda, a small town in the south west of Sweden, took a crucial step toward more sustainable public housing when it turned six apartment blocks into energy-independent buildings by using a combination of PV solar panels, batteries and hydrogen fuel cells.

Besides replacing old devices to put in newer, more efficient ones, there also seems to be a trend toward more complex solutions. For example, Sunfire expects that at some point, entire neighborhoods will be supplied with energy through a combination of solar PV, heat pump and large fuel cell devices. These multi-energy residential systems will no longer produce heat and power for individual buildings but several residential units at once.

Among all German states, Brandenburg has had the most trouble striking the right balance between its fossil and renewable sources of energy. Many jobs in the south of state depend on lignite mining, while large wind farms have been put up in the north and around Berlin. The state government, a coalition of The Left and the SPD, has been trying for years to find an equitable solution to its very own energy dilemma.

Concentration on Hydrogen and Fuel Cells

Concentration on Hydrogen and Fuel Cells

I’ve been following the hydrogen and fuel cell industry for 20 years. In 1997, you couldn’t even call it a niche market. Back then, many engineers didn’t know the term “fuel cell” existed at all and hydrogen was just another element of the periodic table. Only a handful of companies were tinkering with metal hydride storage or phosphoric acid fuel cells. Within a few years, the technology became the latest development everyone in the automotive and heating industry was pinning their hopes on. But nothing came of the ambitious plans businesses were announcing. Even years later, the situation hadn’t changed. (more…)
