Accelerating solar-plus-storage key to boosting the efficiency & resilience of global energy networks, making clean energy supply more reliable

14 June 2023

Accelerating solar-plus-storage in the next five years will be important for boosting the efficiency and resilience of global energy networks, according to 92% of energy industry professionals.

The finding is from DNV’s Industry Insights research, which surveyed global energy industry professionals on their outlook, expectations and priorities for the year ahead. Frequently referred to as the ‘power couple’ of the energy world, combining solar and storage aims to tackle the intermittency of solar power. 

DNV’s Energy Transition Outlook forecasts that solar will grow 20-fold globally by 2050 and installations are increasingly being planned with dedicated storage. Within a decade, about one-fifth of all PV installed will be with dedicated storage, and by mid-century, this share will have risen to half.

“Global emissions are continuing to rise; the good news is that we have the technologies to prevent further increase of emissions. Combining solar and storage also opens a wide range of possibilities to provide 100% renewable energy for society in a reliable and cost-efficient way. It’s important that we act fast for the collective good, remove barriers to clean energy and plan for long-term progress,” says Ditlev Engel, CEO of Energy Systems at DNV.

The forecast also shows that despite its current higher costs, solar-plus-storage has an advantage over solar PV on capture price. Plants with storage can charge batteries when sunlight is plentiful during the day and sell the stored electricity when the price is high. By 2038, the capture price advantage of solar-plus-storage over regular solar PV plants will surpass the cost disadvantage on a globally averaged basis.  

Of those surveyed for Industry Insights, respondents working in the solar industry clearly see investment in storage as a priority, with two-thirds revealing they already have revenue-producing business interests in the sector and 56% expecting to increase their investment in the year ahead.

However, skills shortages and lack of policy support could stand in the way of progress, with both solar and storage industry respondents citing these as the biggest barriers to growth.

Sixty-three percent of respondents from the solar industry stated that not enough people are entering the workforce in the sector. Sixty-two percent revealed that their own organization is finding it increasingly difficult to attract employees with the skills required for the energy transition.

Digital tools that speed up the implementation and management of solar-plus-storage projects will drive the uptake of this technology. GreenPowerMonitor, a DNV company will be showcasing their offering (including advanced analytics for underperformance detection) at this year’s Intersolar in Munich.

When it comes to policy support, 47% believe that inadequacy, delays or surprises in public policy represent the biggest risk to their organization’s near-term success. A further 87% of solar industry respondents stated that reforms to permitting and licensing processes are critical to meeting net-zero targets.

DNV’s Industry Insights research was conducted in January and May 2023 and includes over 1,500 respondents from Europe, North America, Latin America and Asia Pacific.
