Electric vehicles: chargers of the light brigade?
This 14-page note compares the economics of EV charging stations with conventional fuel retail stations. Our main question is whether EV chargers will ultimately get over-built. Hence prospects may be best for charging equipment and component manufacturers.

Solar+battery co-deployments: output profiles?
Solar+battery co-deployments allow a large and volatile solar asset to produce a moderate-sized and non-volatile power output, during 40-50% of all the hours throughout a calendar year. The smooth output is easier to integrate with power grids, including with a smaller grid connection. The battery will realistically cycle 100-300 times per year.

Sentient Energy: smart grid breakthrough?
This data-file is a technology review for Sentient Energy, assessing innovations in smart grids. Its technology can achieve energy savings via a combination of “Conservation Voltage Reduction” and “Volt-VAR optimization at the grid edge”. This also helps to integrate more solar and EV charging into power grids. We explain the technology.

Road costs: economic model?
A typical road costs $3M/lane-km to construct, with an effective cost of $0.25 per vehicle-km subsequently travelled. The range varies with utilization and road complexity. Around 10% of the costs are materials, mainly aggregates, while the remainder of the capex is spent on construction and engineering.

Australia energy supply-demand model?
Australia’s useful energy consumption rises from 820TWH pa in 2023, by 1.2% pa 1,100 TWH pa in 2050. As a world-leader in renewables, it makes for an interesting case study. This Australia energy supply-demand model is disaggreated across 215 line items, broken down by source, by use, from 1990 to 2023, and with our forecasts…

Demand shifting: electrical flexibility by industry?
Demand shifting flexes electrical loads in a power grid, to smooth volatility and absorb more renewables. This database scores technical potential and economical potential of different electricity-consuming processes to shift demand, across materials, manufacturing, industrial heat, transportation, utilities, residential HVAC and commercial loads.

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…
