Fire safety engineering researchers have demonstrated increasing the gap between the modules of commercial PV arrays and flat roof surfaces is a decisive factor in reducing fire risks. Experiments have identified a critical gap height below which flame spread rate increases significantly.

Researchers in Denmark have developed water-based nanofibers coated with a biological PV substance which can be easily injected into the body. The developers say excitable cells in the heart and brain could be regenerated by being electrically stimulated with the solution.

By this time next year we may be able to wave goodbye to that old chestnut about renewables endangering security of supply. Elsewhere, the price of lithium – and the products it goes into – could go either way after tanking this year.

Battery innovations started to come thick and fast this quarter as the hunt for alternatives to lithium-ion intensified and the latest slew of solar tenders indicated the relentless pressure on solar power generation costs was showing no sign of abating.

The Danish government has agreed to provide $19 million in funds for two large-scale hydrogen projects under development on the Jutland peninsula. The two projects will produce green hydrogen for the transport sector from renewables sources. Denmark’s largest energy company, Ørsted, has also announced plans for an ambitious 2 MW electrolysis plant with appurtenant hydrogen storage.

As solar and wind power enter the post-subsidy era, the next few years will be critical for China’s energy transition with investors learning to navigate the uncertainties of market reforms. With the 14th five-year plan – touted as a watershed in China’s energy system development – in the works, a report has recommended clear targets for 2021-2025 in terms of solar and wind power deployment and a reduction of coal consumption.

A week after the Danish government announced it may stop holding auctions for new solar and wind capacity a 155 MW unsubsidized solar project has been announced for the Jutland region. The plant will initially sell electricity to the Nordpool electricity market but its developers are also considering private supply deals.

Digital imagery with laser lights has been used to measure a solar cell’s performance for some time now through a process called light beam induced current (LBIC) mapping. However, due to the serial nature of image processing, it hasn’t been easy to do quickly. Danish start-up InfinityPV says it has employed a method that will expedite the LBIC speed by more than 10 million times.

The Danish Energy Agency allocated 252 MW of clean energy generation capacity, of which 83 MW was solar and 93 MW solar-wind hybrid facilities which included 34.1 MW of PV capacity. The average price premium to be paid on top of wholesale electricity rates to the successful bidders has fallen 30% in a year, prompting the authorities to muse they may be allocating too much public money to support such projects.

Britain’s renewable energy trade body has published a report examining the state of flexibility market readiness in nine European markets. The result makes for sobering reading for Germany, France and the U.K.
