  • Amprius: silicon anode technology review?

    Amprius: silicon anode technology review?

    Amprius is commercializing a lithium-ion battery with a near-100% silicon anode, yielding 80% higher energy density. It can achieve 80% charge within 6-minutes. The company is listed on NYSE. We have reviewed Amprius’ silicon anode technology. The patent library is excellent, goes back to 2009 and has locked upon a specific design. This allows us…

  • Aker Carbon Capture: technology review?

    Aker Carbon Capture: technology review?

    Aker Carbon Capture is a public company, listed in Norway, with c120 permanent employees. It has developed novel solvents for post-combustion carbon capture, modular CCS plants (JustCatch, at 40-100kTpa, and BigCatch at >400kTpa). The company aims to secure contracts for 10MTpa of CCS by 2025. This technology review looks for a moat in the patents.

  • MIRALON: turquoise hydrogen breakthrough?

    MIRALON: turquoise hydrogen breakthrough?

    MIRALON is an advanced material, being commercialized by Huntsman, purifying carbon nanotubes from the pyrolysis of methane and also yielding turquoise hydrogen. This data-file reviews MIRALON technology, patents, and a strong moat. Our model sees 15% IRRs if Huntsman reaches a medium-term cost target of $10/kg MIRALON and $1/kg H2.

  • Redox flow batteries: costs and capex?

    Redox flow batteries: costs and capex?

    Redox flow battery costs are built up in this data-file, especially for Vanadium redox flow. In our base case, a 6-hour battery that charges and discharges daily needs a storage spread of 20c/kWh to earn a 10% IRR on $3,000/kW of up-front capex. Longer-duration redox flow batteries start to out-compete lithium ion batteries for grid-scale…

  • Thermal energy storage: cost model?

    Thermal energy storage: cost model?

    This data-file captures the costs of thermal energy storage, buying renewable electricity, heating up a storage media, then releasing the heat for industrial, commercial or residential use. Our base case requires 13.5 c/kWh-th for a 10% IRR, however 5-10 c/kWh-th heat could be achieved with lower capex costs.

  • Sugar production: the economics?

    Sugar production: the economics?

    The costs of sugar production are estimated at $260/ton for a 10% IRR at a world-scale sugar refinery, in a major sugar-producing region. Higher returns are achievable at recent world sugar prices, and by valorizing waste streams such as molasses for ethanol and bagasse for cogenerated electricity.

  • Solar plus batteries: the case for co-deployment?

    Solar plus batteries: the case for co-deployment?

    This 9-page study finds unexpectedly strong support for co-deploying grid-scale batteries together with solar. The resultant output is stable, has synthetic inertia, is easier to interconnect in bottlenecked grids, and can be economically justified. What upside for grid-scale batteries?
