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.

Interview: The Energy Charts, developed by the Fraunhofer Institute for Solar Energy Systems (ISE) shows that the switch from coal to gas in Germany reduced CO2 emissions by one third in June. In a European wide transition, Eurogas General Secretary James Watson considers reductions of up to 45% possible by 2030. The gas sector is also willing to make the transition to renewables and decarbonised gases by the middle of the century. In the case of power-to-gas technologies, medium-term cost reductions which are comparable to the experience curve of photovoltaics is possible, Watson explained.

The IFC and the country’s power utility are planning to build small on-grid solar parks across three to five different sites, and are seeking a project consultant.

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.

UK based energy data service provider and consultancy EnAppSys released its quarterly review of the European energy market. While renewables have covered a large chunk of the continent’s demand, that trend will likely change in the second half of the year, as production from renewables falls. Meanwhile, coal generation is being pushed out of the U.K. market, although not fully to the benefit of renewables as gas-fired power plants are picking up momentum.

The huge floating plant is expected to be located on a water surface close to the Saemangeum, an estuarine tidal flat on the coast of the Yellow Sea. Construction on the facility is planned to start in the second half of next year. Around 4.6 trillion won ($3.9 billion) of private funds will be invested in the project.

Part three of our series on solar’s less covered markets takes us to Belgium, where despite impressive instsllation numbers from the rooftop market, a lack of volume means the country is unlikely to hit its EU mandated 2020 targets for renewable energy.

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 $10m 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.

Chinese thin film manufacturer Hanergy has announced plans to integrate its CIGS modules into the 150,000 square meter rooftop of a ‘sky bridge’ project planned as part of a major ‘tech city’ project under construction in Shanghai.
