Scientists at Germany’s Karlsruhe Institute of Technology have developed a new class of electrolytes they say could bring calcium batteries – currently only a lab technology – a step closer to being a practical reality for energy storage.

The Consortium for Battery Innovation has outlined research goals for advanced lead-based battery concepts, claiming the potential of the technology is “nowhere near fully exploited”. The group, comprised of lead-battery industry stakeholders, says such devices can play an important role alongside lithium-ion and other storage technologies in electric vehicles, renewable energy storage and other applications.

The governmental body responsible for keeping mine pollution out of waterways has announced completion of the first phase of a plan to use solar to keep down its electricity bills.

LevelTen claims its online platform offers small companies the chance to band together to buy green energy and connects renewable energy producers and consumers in such an effective manner it has already driven $1 billion of green energy supply in its homeland.

A 6 MW solar plant and 5 MW/2.5 MWh storage system are set to increase the share of renewable electricity on the Pacific island of Nauru from 3% to 47%. The $27 million project is being supported by the Asian Development Bank (ADB).

Take-up has been slow considering the nation’s mammoth agricultural industry but, as a packed session on the topic at the recent Renewable Energy India show illustrated, attitudes may be changing in a nation which is already installing solar greenhouses.

The U.K. province’s grid operator SONI has announced a £500 million plan to prepare the network for an almost fully renewable electricity system within just five years. Despite the U.K. being seemingly paralyzed by Brexit, the network operator says it can already cope with 65% clean energy in the mix.

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.

The latest 8 MW of net metered solar capacity in Dubai indicates 11 MW were added across ten new arrays in just nine days as the Shams initiative continues to work up a head of steam.

Athens-based policy group The Green Tank labelled Greece’s decision “historic” while Europe Beyond Coal, an alliance of civil society groups working to make Europe coal free by 2030 said Hungary should target a more ambitious 2025 phase-out.
