Storage in days, not hours: Temasek Trust's C3H leads Certain Energy's $13.62M round — TNGlobal
The Imperial College spinout builds manganese flow batteries that hold renewable power for days at roughly one-tenth the marginal storage cost of vanadium, with round-trip efficiency above 75% and a twenty-year life.
Positive-sum angle: Long-duration storage priced off an abundant element widens the market for everyone building on intermittent renewables. Solar developers, grid operators and industrial offtakers all get a cheaper firming layer, and each deployment gives the next project a financeable cost curve to underwrite.
What's the impact: The first grid-connected system lands in India, not ASEAN. Indonesian and Philippine developers wrestling with island grids should court manganese-chemistry vendors while pilot slots stay cheap, before firming capacity gets written into the next round of power purchase agreements.
Who owns the road under the data centres? Indosat and Arsari open 86,000 km of fibre — TNGlobal
PT Infra Fiber Teknologi, formed by Arsari Group and Indosat Ooredoo Hutchison with Northstar backing, launched RAIA Grid, a carrier-neutral platform selling 86,000 kilometres of fibre to operators, hyperscalers and data centres.
Positive-sum angle: A carrier-neutral layer turns route diversity into something any operator can buy rather than build. Smaller ISPs, edge providers and regional cloud entrants reach routes that previously required a national incumbent's balance sheet, which lowers the cost of the next data centre in Java.
What's the impact: Indonesian infrastructure builders should treat backhaul as procurable now and compete on the layers above it: interconnection, latency guarantees, data residency. Founders siting compute outside Jakarta gain a route argument they could not make eighteen months ago.
