Energy Storage

To get long-duration storage costs down to $0.05/kWh, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies – even thermovoltaics.

Battery innovations started to come thick and fast this quarter as the hunt for alternatives to lithium-ion intensified and the latest slew of solar tenders indicated the relentless pressure on solar power generation costs was showing no sign of abating.

Developer PowerGen has installed a new mini-grid in the country and plans to develop nine more projects with the support of the World Bank.

Storage has long been expected to be the handmaiden of a renewable energy world and its long awaited advances started to finally emerge in the third quarter as researchers posited R&D achievements ranging from potentially potent tungsten disulfide nanotubes to the business case for 10-year solar panels.

Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.

A monastic community on the Mt Athos peninsula this year installed a solar-storage-diesel mini-grid which is set to be augmented by a biomass combined heat and power system in March.

The first part of pv magazine’s review of 2019 considers Q1, when solar early adopter Italy offered an optimistic start to the year by fleshing out its plans for PV but uncertainty still clouded the world’s biggest solar market. The potential for household solar installations to rocket the world over – helped by ever cheaper panels – prompted strategic decisions in the inverter market and analyst expectations were confounded as the cobalt and lithium price plummeted, bringing the EV revolution a big step nearer.

With demand for lithium-ion battery cells picking up, largely driven by EVs but also from the fast-growing stationary storage segment, production capacities in China are ramping up quickly. But safety and quality must remain centrally important in the face of the need to scale, even more so after the numerous battery fires that shocked buyers globally and brought the South Korean market to a standstill. Clean Energy Associates (CEA) has launched the 2019 BESS Supplier Market Intelligence Program report, covering 40 suppliers, in an effort to support buyers navigating this novel supplier landscape. George Touloupas, CEA’s director of technology and quality for solar and storage, shares the company’s key findings on the supply chain and tells us what can have an impact on Li-ion safety and reliability.

The Danish government has agreed to provide $19 million in funds for two large-scale hydrogen projects under development on the Jutland peninsula. The two projects will produce green hydrogen for the transport sector from renewables sources. Denmark’s largest energy company, Ørsted, has also announced plans for an ambitious 2 MW electrolysis plant with appurtenant hydrogen storage.

Evergen, a solar and battery optimization specialist, and battery supplier Solar Service Group have joined forces to connect thousands of residential batteries across Australia. By delivering significant benefits to consumers, the joint venture hopes to boost the uptake of home batteries across the nation.
