Railway operators can now feasibly connect solar plants to traction substations, claims a consortium that is now working on a similar demonstration project in the U.K. Almost all of the 30 kW installation’s output will be used to move trains, but in the future storage could come into the picture for larger “railway-connected” solar power projects, says 10:10, the U.K.-based climate change charity that developed the pilot.

Australia’s Northern Territory has given major project status to an ambitious plan to develop a 10 GW solar farm coupled with a 20-30 GWh storage facility near Tennant Creek and export solar power harvested in the Australian desert to Singapore via subsea cables.

Analysts have scrutinized the result of the recent A-4 auction which delivered, in theory, the world’s lowest price for solar electricity from an energy procurement exercise. The two plants in question, however, will sell 70% and 50% of their output outside the power deal signed in the auction.

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.

Switzerland deployed 271 MW of PV in 2018. According to Swiss PV association Swissolar, the current levels of development are not enough to meet the targets set by the country’s 2050 energy strategy.

The Anglo-American company is the latest utility to enter the utility-scale solar and wind development space by closing on its acquisition of Geronimo Energy.

In our series of renewable energy and geopolitics interviews, Indra Øverland – head of the Center for Energy Research at the Norwegian Institute for International Affairs – explains why hydropower can be the perfect match for intermittent renewables such as solar and wind. Hydropower assets are one of the biggest geopolitical stories of the energy transition but receive almost no attention. Nations with strong hydro potential may become linchpins of regional renewable energy.

The audit agency said at least half the EU member states will be unable to reach their 2020 renewable energy targets, including the Netherlands, France, Ireland, Poland and the U.K. It recommends citizen participation and more renewable energy auctions to increase investment and raise volume in the EU clean energy sector. Cross border renewables trade and grid improvements are also highlighted as necessary for a successful energy transition.

In a new interview in a series on renewable energy and geopolitics, Indra Overland describes the possible trajectory of China’s bid to become the world’s solar energy leader. After building a leading position in key technologies and manufacturing, China may find a potential partner in the European Union, especially if the U.S. government pushes forward with its trade war against Beijing, Overland says. Solar and renewables are also helping the country expand its influence in Southeast Asia, fuelling concerns among some of its neighbors, he adds.

Although the nation’s PV industry has recently established new landmarks, warnings have been sounded about the immediate outlook for the sector.
