Shared grid connections, complimentary resource availability, and more grid-friendly power are among the key advantages of pairing wind farms with solar arrays – and developers are quickly moving into the emerging space.

Single-axis tracker deployment has increased dramatically in the past two-to-three years, both in terms of the number of PV plants adopting the technology and the sheer size of some tracking systems. Given this, durability in the face of high wind loads has been brought into sharp focus with new testing and calculation methods providing more certainty for EPCs, owners and investors.

The Consortium for Battery Innovation has outlined research goals for advanced lead-based battery concepts, claiming the potential of the technology is “nowhere near fully exploited”. The group, comprised of lead-battery industry stakeholders, says such devices can play an important role alongside lithium-ion and other storage technologies in electric vehicles, renewable energy storage and other applications.

Fundraising activity for solar leaped in the July-to-September period to provide healthy quarterly and year-so-far comparisons on 2018.

When Sony first commercially introduced lithium-ion batteries in 1991, the industry recognized their potential to revolutionize portable electronics. Ever since, there have been countless efforts to improve the technology, with many researchers focusing on energy density and longevity, in line with demand from emerging applications such as electric vehicles (EVs) and on-grid energy storage. Julian Jansen and Youmin Rong of IHS Markit discuss the effect of safety concerns on this rapidly growing global market.

Plans for a gigawatt factory in Saudi Arabia, bullet-proof warranties and an international vanadium rental service are propelling a new generation of batteries into the energy storage big league. Pioneers of redox flow technology claim that they can put an end to the degradation and safety issues afflicting lithium-ion batteries. They also expect imminent economies of scale to reduce the cost of bulk energy storage and unlock new markets for solar power.

The latest edition of the World Nuclear Industry Status Report reiterates that clean power is taking the lead in the world’s energy system and nuclear is not only too costly a remedy for carbon emissions but too slow to deploy.

ANZ has become the latest Australian signatory of The Climate Group’s RE100 initiative, joining a growing pool of businesses in the global transition to a zero carbon grid.

The global expansion of PV, wind power and other clean energies will see double-digit growth this year as solar continues to lead the pack.

Research has found even short-lived, 10 to 15-year solar panels could provide enough return for bankable projects. The researchers believe panel costs, coupled with an industry mindset now fixed on the final solar energy price rather than costs per kilowatt installed, may open opportunities for PV products currently snubbed because of a short lifecycle.
