LDES

TES and CAES are challenging battery storage

According to new analysis thermal and compressed air technology are already cheaper energy storage solutions than battery storage.

According to new analysis by BloombergNEF, thermal and compressed air technology are already cheaper energy storage solutions than battery storage.

The latest research shows the growing competition faced by lithium-ion batteries from emerging long duration energy storage (LDES) solutions. Despite being in the early stages, certain LDES options, like thermal energy and compressed air energy storage (CAES), are demonstrating cost advantages over lithium-ion for longer durations.

Thermal energy storage and CAES, for example, have an average capital expenditure of $232/kWh and $293/kWh, respectively. Lithium-ion batteries meanwhile came in at $304/kWh for four-hour duration systems.

Experts highlight the crucial role of supportive policies and continuous technological advancements in promoting the broader adoption of LDES and boosting their competitiveness with lithium-ion batteries.

The news of the adoption of the Net Zero Industry Act by Governments across the EU will certainly help here too. Julia Souder, CEO of the Long Duration Energy Storage Council, said "It’s clear LDES technologies have entered into a virtuous cycle where growing market adoption is spurring increasing innovation and cost efficiencies.".

Hornsea wind zone: two projects online, Hornsea 3 under way, Hornsea 4 shelved

Ørsted's North Sea development has delivered two of the world's largest offshore wind farms. Its third phase is in construction with Apollo as a half-owner, while the fourth has been discontinued in its current form.

Construction workers in high-visibility clothing and hard hats install large black pipes at a heat network site, with stacked pipe sections and temporary fencing behind them.

Bradford heat network gets £9m government funding boost

The Department for Energy Security and Net Zero has announced £9m to expand Bradford's city-centre low-carbon heat network, with upgrades also planned for existing schemes in Leeds and York.
