Solar changing shape of electricity prices in Northern Europe
Rising volumes of photovoltaic project capacity are increasing the incidence of negative price periods for electricity–and changing the times of day when they occur.
Solar power has to be about quality as well as quantity
Greater dispatchability will be required from solar as it becomes increasingly mainstream worldwide, or investors could experience diminishing returns as a victim of the technology’s success at bearing down on electricity prices.
Battery storage 30% cheaper than gas peaker plants for firming renewables
The contest is over. Faster, cheaper, more flexible than gas turbines – battery energy storage must be the future peaking energy service provider of choice, according to a new paper by Australia’s Clean Energy Council.
Australian researchers target rooftop solar in hunt for grid security
The University of New South Wales is leading a new research project to determine how rooftop solar PV and other distributed energy resources, including small-scale batteries, can be integrated into Australia’s power grid.
Solar could help Azerbaijan consolidate gains in Nagorno Karabakh after recent conflict
That was just one of the revelations of the latest Dentons’ Guide to renewables investment in Europe, which also noted solar plants could be switched off in Slovakia, Ireland could go either way on clean power pricing, and Luxembourg is struggling with a surprising headache.
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.
