Clearly, renewable energy is now a viable alternative to traditional generation from a cost perspective. However solar and wind’s penetration of the grid is constrained by ageing infrastructure, high grid connection costs and their intermittent, weather-dependent nature. Scott McGregor looks at how long-duration energy storage on an industrial scale can help.

Younicos CEO Stephen L. Prince ponders the role of energy storage within the three ‘Ds’ revolutionising energy: digitisation, decentralisation and decarbonisation.

On-board batteries are the way of the future. Energy storage is the right approach to make energy systems on board ships more intelligent and efficient. Energy storage systems can be especially beneficial on vessels with a widely fluctuating fuel consumption profile. Nidec ASI discuss two recent projects to bring battery storage onto such vessels.

To date, Primary Control Reserve (PCR) has dominated the energy storage debate in Germany with more than 100MW of battery storage installed in 2016 alone specifically for participating in the PCR market. At the same time, with close to 25,000 systems sold in 2016, residential storage has been stealing the limelight in the behind-the-meter segment. Julian Jansen of Delta-ee looks at how his team expects the commercial and industrial (C&I) segment to start catching up.

Each battery storage system is a potential source of danger. An ingenious battery management system as well as high-quality cells are the key to a safe operation. For this you need a lot of know-how. Dr Olaf Wollersheim of Solarwatt talks through some of the main topics and solutions.

Software platforms are emerging as a crucial element in the rapidly expanding energy storage industry. Alex Eller of Navigant Research explains the crucial role software plays in underpinning the value of energy storage systems.

The complexities of combining batteries and solar microgrids are explained by Sam Duby, who is co-founder and director of research and development at mini-grid technologies company SteamaCo Ltd and consults for TFE Consulting. TFE Consulting is a strategy consulting firm focusing on accelerating the energy transition in emerging markets and is active in Africa, India, Southeast Asia and Latin America.

Increasing Li-ion demand will help to continue to lower energy storage costs, but also brings up an important issue: what should be done with the batteries after they are used in vehicles? Chris Robinson of Lux Research weighs up the pros and cons of recycling versus repurposing for second-life use.

To date, the vast majority of the entries into the energy storage market have depended on lithium-based battery chemistry, but, the idea that lithium-ion is the technological and economic front-runner in the stationary storage space is a myth that is in dire need of de-bunking, claims Ron Van Dell.
