Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.
A floating solar array will be located in the North Sea near an aquaculture and an offshore wind power facility. The €2 million pilot project is being developed by a consortium including Tractebel, Jan De Nul Group, Deme, Soltech and Ghent University.
Canadian gas giant ATCO has unveiled its Clean Energy Hub in Jandakot which will explore the potential of hydrogen for home use in gas appliances. On the same day, the Western Australian government has launched a renewable hydrogen strategy and announced the creation of a $10 green hydrogen fund.
Crossboundary Energy Access (CBEA) was established in January with large investment contributions from Rockefeller and Shell Foundations. The funding facility, which said it would work to unlock $11 billion in funding for the electrification of 100 million people in Africa, has penciled its first transaction with PowerGen Renewable Energy.
A new paper published by scientists from the Massachusetts Institute of Technology examines the potential for integrating small solar cells into the wireless sensors needed to power the fast-growing internet of things (IoT) ecosystem, many of which are located indoors. This market could represent a unique opportunity for thin film PV technologies, and perovskites in particular, to reduce the risk inherent to ramping up commercial scale production.
… and it will be quite an effort. The U.K.’s grid operator, National Grid, released a new report on possible energy system transformation pathways, amidst growing public concern over climate change. Ramping carbon emissions reduction targets up from 80% to 100% prompts technical challenges. These can be overcome but will require full alignment of policy effort and individual awareness and decision making.
Scientists at Pennsylvania State University have developed a new class of perovskite materials, which they say exhibits unique properties that could have several implications for the development of perovskite solar cells, as well as other electronic applications.
Scientists at Saudi Arabia’s King Abdullah University of Science Technology have set a new efficiency record of 21.09% for a single crystal perovskite. The researchers say this highlights a place for the technology to develop alongside the multicrystalline versions which are progressing toward commercialization.
In pursuit of a lower levelized cost of energy for the next generation of inverters, some manufacturers have turned to acquiring considerably more expensive semiconductors. While this may sound like a misstep at first, the trick could be pulled off — though not easily, and not always — yet.
