How variable is rooftop solar power?
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
Photovoltaics vs. concentrated solar power
Omani researchers have compared the performance of PV and concentrated solar power (CSP) in terms of energy generation intensity and the effective use of land at low latitudes near the Tropic of Cancer. They described nine project typologies and ranked them with three different simulation tools.
Floating PV for water pumping, desalination
An irrigation community has built a 786 kW floating solar array on a small water reservoir in Murcia, Spain. The facility will provide power for a solar water pumping system, a desalination unit, and the community itself.
Market operator launches grid connections tool
The Australian Energy Market Operator has launched an online connections simulator designed to improve and accelerate the grid-connection process for new energy generation and storage projects in the National Electricity Market.
Neoen signs connection agreement for Goyder South project
Renewable energy developer Neoen has inked a connection agreement with network operator ElectraNet which will allow for the first stage of its $3 billion (USD 2 billion) Goyder South project to connect to the grid in South Australia, paving the way for future wind, solar and battery storage opportunities at the site.
Martin Green’s solar cell efficiencies at a glance updated
A research group led by Professor Martin Green has published Version 61 of the solar cell efficiency tables. The tables include a world record for a silicon heterojunction cell, announced by Longi earlier this week, as well as five more new results.
Lithium-vanadium battery for renewables storage
AMG Advanced Metallurgical Group has energised its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.
Rise of renewables sparks closure of Torrens Island gas power plant
Energy giant AGL has disclosed it will shutter its gas-fired Torrens Island B power station in South Australia within four years, citing the impending completion of a new electricity interconnector that will link power grids across three Australian states, unlocking gigawatts of new wind, solar PV and storage projects.
Building renewables emits carbon, but building them faster emits far less
A new study by Columbia University’s Climate School looks at the carbon emissions needed to build renewable energy.
Feds give CEFC $500m funding boost for renewable tech commercialisation
The Clean Energy Finance Corporation, effectively the federal government’s green bank, has been allocated a further $500 million (USD 332 million) to invest in the commercialisation of renewable energy, energy efficiency and other technology innovations.
