  • New energies: the age of materials?

    New energies: the age of materials?

    Over the past decade, costs have deflated by 85% for lithium ion batteries, 75% for solar and 25% for onshore wind. Now new energies are entering a new era. Future costs are mainly determined by materials. Bottlenecks matter. Deflation is slower. Even higher-grade materials are needed to raise efficiency. This 14-page note explores the new…

  • Overview of inertia in renewable-heavy grids?

    Overview of inertia in renewable-heavy grids?

    This overview of inertia in renewable-heavy grids tabulates the typical inertia of rotating generators, then models the resultant Rate of Change of Frequency (ROCOF) during supply disruptions. In our base case, a grid with 6 MW-s/MVA of inertia rides through a 2% supply-disruption, buffered by 1% fast frequency response (FFR), via lowering grid frequency from…

  • Data center energy: caps lock?

    Data center energy: caps lock?

    Everybody knows “AI data centers use round-the-clock power”. Yet one of the biggest power challenges for AI data data centers is precisely that they do not use round-the-clock power. They incur large load transients that cannot be handled by batteries, power grids or most generation. This 15-page report explores data center load profiles, which may…

  • Verdox: DAC technology breakthrough?

    Verdox: DAC technology breakthrough?

    This data-file reviews Verdox DAC technology, optimizing polyanthraquinones and polynaphthoquinones, then depositing them on porous carbon nano-tube scaffolds. These quinones are shown to selectively adsorb CO2 when a voltage is applied, then desorb them when a reverse voltage is applied, unlocking 70% lower energy penalties than incumbent DAC?

  • Grid-scale battery operation: a case study?

    Grid-scale battery operation: a case study?

    Grid-scale batteries are not simply operated to store up excess renewables and move them to non-windy and non-sunny moments, in order to increase reneawble penetration rates. Their key practical rationale is providing short-term grid stability to increasingly volatile grids that need ‘synthetic inertia’. Their key economic rationale is arbitrage. Numbers are borne out by our…

  • Pumped hydro: the economics?

    Pumped hydro: the economics?

    This data-file assesses pumped hydro costs, to back up wind and solar. A typical project has 0.5GW of capacity, 12-hours storage duration, 80% efficiency, and capex costs of $2,250/kW. Thus it requires a 25c/kWh storage spread, in order to generate a 10% IRR.

  • Rare Earth mining and refining: the economics?

    Rare Earth mining and refining: the economics?

    The costs of Rare Earth mining and refining are captured in this model, requiring a $70/kg blended product price, to generate a 20% IRR on $150,000/Tpa of capex. Primary energy intensity exceeds 100 MWH/ton and CO2 intensity exceeds 20 tons/ton. Economics are particularly sensitive to ore grade, recovery rates and chemical costs.

  • Redox flow batteries: for the duration?

    Redox flow batteries: for the duration?

    Redox flow batteries have 6-24 hour durations and require 15-20c/kWh storage spreads. They will increasingly compete with lithium ion batteries in grid-scale storage. Does this unlock a step-change for peak renewables penetration? Or create 3-30x upside for total global Vanadium demand? This 15-page note is our outlook for redox flow batteries.

  • Capital goods market sizes: by category, by country?

    Capital goods market sizes: by category, by country?

    This data-file tabulates globally traded capital goods market sizes, based on the values of products exported from different countries-regions. Specifically, commodity Code 84 represents machinery and mechanical appliances, worth $2.5trn pa in 2023. About half of that represents classic capital goods categories, as decomposed in the chart above. Our top five conclusions follow below.
