Where next for China’s energy transition?

A late rally boosted China’s domestic solar installations in 2019 to a better-than-expected 30.22GW. But Frank Haugwitz asks whether a renewed interest in locally available coal and an economic slowdown could conspire to slow recent momentum in China’s energy transition, in which solar has played a central role.

PV and ESS in Japan’s changing energy market landscape

It has always been anticipated that by the early 2020s, the feed-in tariff would have tapered away in Japan’s booming solar market. Andy Colthorpe speaks with analyst Izumi Kaizuka at RTS Corporation to learn more about what the future holds for post-subsidy solar in Japan.

Turkish PV defies political ghosts in year of the rooftop

New stats show Turkish solar has swiftly boomed to 6GW despite the national chaos after the 2016 coup attempt. Can the country continue to dodge volatility as it vies to become a 1GW-a-year PV market via a mix of large-scale and net-metering policies? José Rojo investigates.

Modi’s mission

India’s government insists that its target of 100GW solar by 2022 is still on track. But after 2019 proved another disappointing year, will the sector’s barriers be overcome in time? Catherine Early reports.

Fine tuning the hybrid proposition

Realising the theoretical promise of solar-wind-storage hybrids is far from straightforward, with individual projects likely to vary considerably. Ben Willis examines some of the technical complexities of combining different technologies into a single, profitable entity.

Taking charge: Energy Storage Association CEO Kelly Speakes-Backman

Despite making huge strides forward, the energy storage industry’s work in helping stakeholders across the value chain understand the technologies and the roles they can play in a renewable energy future is far from done. Andy Colthorpe speaks with Energy Storage Association chief executive, Kelly Speakes-Backman, at the forefront of the industry’s push into unchartered regulatory, policy and public affairs matters.

Contenders: Long-duration technologies and who’s behind them

While lithium-ion batteries get most of the headlines, long-duration energy storage solutions are gaining ground. Alice Grundy and Andy Colthorpe profile some of established and emerging concepts in this this increasingly important class of storage technologies.

Redox flow batteries for renewable energy storage

As energy storage becomes an increasingly integral part of a renewables-based electricity system, new technologies are coming to the fore. Jens Noack, Nataliya Roznyatovskaya, Chris Menictas and Maria Skyllas-Kazacos from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technology and the University of New South Wales, chart the rise of redox flow batteries, a promising alternative to lithium-ion-based systems.

Merchant renewables: a viable investment or a bubble fit to burst?

After several years with a moratorium on renewable energy incentives and no new build, Spain is seeing a new generation of projects being developed without subsidies as grid parity is achieved. Whilst this has encouraged an increase in renewable energy projects, it could be harmful to profits and have serious economic risks for investors. ÅF Pöyry Management Consulting’s Javier Revuelta considers the potential risks of taking a long-lasting grid parity in Spain for granted, how to mitigate these problems, and why it’s relevant to us all.
