New aluminum batteries for renewables storage
The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.

Is This The Next Big Thing In Solar?
Solar power installations out in the open are a common sight in many parts of the world, but how about household solar generators? A team of Swedish and Chinese scientists recently reported this might become part of our future after they successfully converted indoor light to electricity using organic photovoltaic cells.

The slow, inexorable rise of green hydrogen
The International Renewable Energy Association says the integration of hydrogen into the energy transition will not happen overnight and electrolysis costs will not be halved until the 2040s. That hydrogen and related products could revolutionize the world energy landscape, however, is not in doubt.

Live fast, die young: MIT study proposes use of 10-year panels
Research has found even short-lived, 10 to 15-year solar panels could provide enough return for bankable projects. The researchers believe panel costs, coupled with an industry mindset now fixed on the final solar energy price rather than costs per kilowatt installed, may open opportunities for PV products currently snubbed because of a short lifecycle.

Solar, renewables and hydrogen for greener marine transport
A new report in Sweden suggests that renewables are an ideal source of power for marine vessels, based on a case study in which solar PV and proton-exchange membrane fuel cells, combined with a diesel generator, were used to reduce the greenhouse gas and particulate emissions of cruise ships by almost 10%

The blackest black for more efficient solar cells
MIT scientists claim to have created a material 10 times more black than anything witnessed to date. It is said to be able to absorb more than 99.96% of incoming light and reflect 10 times less light than other superblack materials. The invention may be interesting for the development of black silicon PV technology and carbon nanotube-based solar cells.

SMA: We can’t be credible if we’re not sustainable
Credibility comes not just from offering products that generate clean electricity, but also from the way in which those products are manufactured, says SMA Solar Technology CEO Jürgen Reinert. Here, transparency and sustainability are key. That’s why one of the world’s largest PV inverter producers has partnered with pv magazine’s UP sustainability initiative. In the following Q&A, Reinert lays out what SMA is doing to step UP its green game.
