Renewables could provide Australia with grid security, study shows
New research shows that renewables plus batteries could offer Australia’s electricity grid the same energy security as coal and gas generators, prompting calls for regulatory changes.
What will African nations require to produce competitive green hydrogen exports?
A robust national strategy, a portfolio of renewable energy assets, public subsidies and, ideally, existing gas pipelines will all favor African nations aiming to become exporters in the energy storage medium, participants heard at a recent two-day green hydrogen conference.
Solar could address Albania’s climate-change-sensitive hydropower dependency
Photovoltaics could offer peak generation at times of the year when the nation needs it most, says IRENA, but plenty will have to be done, including upgrading an aging grid and training an army of installers and building energy auditors.
Incentives crucial to avoid green, blue, and even purple hydrogen fading to grey
An Anglo-German report has suggested the environmentally-friendly desire to use only clean power to produce hydrogen, outlined by nations such as Germany, could end up being more emissions-heavy than the more pragmatic embrace of blue hydrogen under consideration in the U.K.
Greece, Cyprus and Israel take a further step to link their grids
The three Mediterranean countries of Greece, Cyprus and Israel signed this week an agreement to develop a subsea cable that links their electricity grids. Upon completion, the so-called EuroAsia Interconnector will be the world’s longest subsea power cable and could boost solar PV development in all three countries substantially.
Solar mini-grid to protect Austrian highway from blackouts
The Austrian motorway company Asfinag is planning to power, with solar-plus-storage, all its maintenance facilities. These installations are planned to power the stations at night and in the event of a grid failure.
Mongolia has first smart grid management system installed–from the UK
Covid-19 border closures meant the first ‘active network management’ system was planned and commissioned for the Asian nation by the U.K. division of Saudi-owned smart grid specialist ZIV Automation.
Solar could play big role in helping renewables displace UK’s planned gas fleet
Each 1.8 GW of new gas generation capacity could be replaced by 1.7 GW of solar as part of a cleaner, 6.3 GW collection of renewables and energy storage facilities–and that alternative already comes in cheaper than the business-as-usual approach, according to the Carbon Tracker thinktank.
New power electronic device to manage surplus solar power–Part II
The first pilot tests have been conducted for the EU-funded project ‘renewable penetration levered by efficient low-voltage distribution grids (RESOLvD). pv magazine has looked into the demonstrator and the related energy sharing algorithm.
Dutch grid operator mulls incentives to reduce or curtail solar
The Limburg section of the network could face congestion problems for a decade, according to transmission system operator Tennet, prompting talk of offering auction-determined incentives to clean-power generators to reduce their output.
