    Operating in a vicious cycle

    When project developers evaluate the potential profits for a new battery project in the NEM, one key variable being considered is the maximum allowable cycling rate of the battery. Cycling at higher rates can enable more arbitrage profits to be earned, but every MWh of energy that passes through the...

    How does thermal storage stack up compared to batteries?

    Along with the retirement of coal/gas power plants in the NEM, long-duration energy storage systems (LDESS), often exceeding 8 hours of storage, are becoming more crucial in transitioning to a more sustainable and renewable energy future. LDESS technologies, such as battery storage systems (BESS), thermal energy storage systems (TESS), compressed...

    Hydrogen hype: How cheap the hydrogen from electrolysis can be?

    Hydrogen is considered a potential replacement for fossil fuels for energy generation, transport etc. Currently, 96% of hydrogen production originates from fossil fuels through steam reforming and coal gasifications. Only a small fraction (~4%) is produced via electrolysis. The high Capex of the electrolyser is usually referred to as the...

    Australian Chart of the week | One of these things is not like the others: FCAS separation value

    Energy storage has been at the forefront of conversations resulting from AEMO’s newly released 2020 Integrated System Plan (ISP). The ISP states that 6-19GW of dispatchable resources are needed to support more than 26GW of new renewables. So where will battery energy storage fit in and where will they make...

    Pixie Chart of the week | CAISO investigates battery energy storage

    On 3 December 2019, CAISO presented its learnings when investigating the potential to use batteries to bridge the gap between peak solar generation and peak demand. In this week’s Pixie Chart of the Week, we take a look at load, net and generation vs Real Time Daily (RTD) prices in the Californian...
