Utility Scale Storage

Professor Thomas Nann told pv magazine Australia that a breakthrough idea was almost too simple: “Actually when we submitted the patent in the first place, the patent officers came back to us and said ‘well, that’s too trivial’ and we made exactly that argument – why did no one else do that then?” said Nann.

The Solar Energy Corporation of India (SECI) shall sign a 25-year power purchase agreement with the successful bidders for these energy storage system projects. The projects are to be set up on a build-own-operate basis.

We will need 10.7 TW of clean energy generation capacity this decade to stay on track with the most ambitious of the climate change paths agreed in Paris, which would include plenty of solar investment and jobs, according to the International Renewable Energy Agency.

With many developers now working on solar+storage projects, it’s time to look more closely at specific business plans. Siobhán Green, lead on battery storage in continental Europe for Everoze, looks at three key questions.

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.

The energy company says it will use hybrid-technology projects, round-the-clock renewables, battery storage, floating solar and green hydrogen as it attempts to wind down the 69% of its energy generation fleet based on thermal power.

LNJ Bhilwara, a diversified business group with presence in graphite electrode manufacturing, has formed a joint venture with Pune-based Replus Engitech to create lithium battery solutions for both e-mobility and stationary applications. The JV aims to have 1 GWh capacity operational in Pune by mid-2022 and eventually scale it to 5 GWh by 2024. 

The State-run power producer has more than 65 GW of installed capacity comprising gas, coal, hydro, and renewable energy based power stations.

The diversified business group will invest over INR 60,000 crore ((US$ 8.1 billion) over the next three years to build Giga factories for solar, energy storage, electrolyzers, and fuel cells, respectively, to create a fully integrated, end-to-end renewables energy ecosystem. Additional INR 15,000 crore (US$ 2 billion) is planned to create a value chain, partnerships, and future technologies.

If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?
