More in store

The battery energy storage system (BESS) market is expected to double year on year in 2021, exceeding a volume of 10 GW, according to IHS Markit (pp. 12-13). For many this would appear an outstanding performance and a sign that battery deployment is at an inflection point – with nothing but good times in store.

Solar’s shipment struggle

The outlook for U.S. residential solar remains strong, according to Jesse Pichel of ROTH Capital Partners. The large-scale segment, however, is hampered by rising costs and the likelihood of sanctions on Xinjiang-made materials.

Sky’s the limit

The sky is the limit. Fortunately, this expression does not apply to current prices for PV panels, which have recently declined, following a continuous rise since the beginning of the year. Whether this situation holds, or whether prices drop further in the coming months is hard to say at the moment, writes Martin Schachinger of pvXchange. Polysilicon prices and thus wafer and cell prices could be in for a slight decline. However, a decisive movement in module prices in general is unlikely before the fourth quarter.

V2G outlook

Multiple drivers are combining to allow battery capacity in electric vehicles to be used as a grid asset through vehicle-to-grid technology, writes George Hilton, senior analyst for energy storage at IHS Markit. Vehicle-to-grid tech could offer low-cost energy storage at a huge scale, but there are many barriers to overcome.

Post-SNEC storage

China’s battery manufacturing industry is growing robustly in line with the rapid expansion of the electric vehicle market. The stationary storage sector currently lags behind developments in leading markets such as the United States and Europe, but strong growth is expected between now and 2030, driven by supportive policies. Fang-Wei Yuan, a senior analyst at InfoLink, examines the latest developments in China’s energy storage industry and looks at the announcements and product launches made at the Shanghai SNEC exhibition back in June.

EV race heats up

The race to electrify passenger cars is picking up pace, writes Prachi Mehta, senior research analyst for Wood Mackenzie. Competition among leading EV automakers is fierce, as 2024 looms as a watershed year when auto battery-pack prices cross a key consumer threshold.

Stored potential

As solar and wind make up larger portions of the energy mix, energy storage is becoming an increasingly important piece of the puzzle in keeping electricity networks running smoothly. And as battery costs fall, new business models are emerging to increase the value of battery energy storage projects for both grid operators and project owners. Focusing on two leading countries – the United Kingdom and Australia – pv magazine looks at what’s in store for large-scale energy storage.

Dirty double standard on display

Australia’s proposed 26 GW Asian Renewable Energy Hub has encountered what appears to be a governmental double standard, as the country’s environment minister has rejected an expanded proposal. Thankfully, the project’s proponents have not become discouraged in the face of this double standard; in fact, they’re doubling down.

A lifetime plan for your solar+storage asset

For developers and investors who are ready to start talking about solar+storage projects, there are some interesting and not so straightforward decisions to be made on the sizing of assets. Siobhán Green, lead on battery storage in continental Europe for Everoze, looks at the different approaches to sizing and how to choose between them. In particular, she assesses the ‘lifetime’ factors to dimensioning and discusses how to plan for degradation and potential through-life resets to the revenue stack.

Hot thermal hopes

Thermal energy storage is dense, efficient, and suitable for greenfield and brownfield projects, with a potentially long lifespan. It can also be built with recyclable or low-impact storage materials. So why is it taking so long to achieve widespread commercial success? Tristan Rayner explores the latest developments.
