LONG-DURATION ENERGY STORAGE
Diversifying the multi-day storage layer.
IMVE is exploring whether Dutch salt-cavern adiabatic CAES can complement batteries, hydrogen, and other long-duration technologies as part of a resilient European storage portfolio.
THE CHALLENGE
Europe does not need a single storage winner. It needs a portfolio.
Lithium-ion is the workhorse for fast response and daily cycling, and it's hard to beat there. A new generation of long-duration batteries — flow, metal-air — is now pushing into the multi-hour and multi-day range, much of it being built here in the Netherlands. Hydrogen will carry the seasonal storage, the industrial feedstock, and the sectors that are hard to electrify at all.
What interests me is the layer in between, where the economics stop being about round-trip efficiency and start being about power rating, asset life, local geology, and not leaning the whole system on one supply chain.
CAES doesn't replace batteries, it sits alongside them. The real question is narrower: can Dutch salt-cavern adiabatic CAES earn a place in that mix, as one part of a diversified long-duration portfolio for the Northern Netherlands?
THE APPROACH
A credible, European answer to the multi-day gap.
IMVE is testing whether local geology, European engineering capability, and existing energy infrastructure can support a credible long-duration storage platform. The current work is pre-feasibility: stress-testing cavern access, permitting, revenue design, and technical integration before moving toward a scoped feasibility phase.
Diversified by design
A resilient grid needs several long-duration technologies, not one. CAES decouples energy from power, so at high power across many hours its cost structure is hard to beat.
European resources
Built on the subsurface geology, engineering, and supply chains that already exist on the continent.
Sovereign value
Keeping the know-how and the assets of the energy transition on European soil.
THE ASK
Stress-test the thesis
I am speaking with operators, researchers, investors, and regional stakeholders to test whether this concept deserves a scoped feasibility phase.
