Electricity costs

Experience from California during the 1990s indicates that biomass plants were able to operate profitably when the wholesale cost of electricity was

$0.040/kWh; they did, however benefit from a subsidy of $0.015/kWh, suggesting that they could generate power for $0.055/kWh. More generally, a plant with an efficiency of around 23% could deliver power at $0.05/kWh provided the cost of the fuel was below $1/GJ, or well below the cost at which fuel will be available in the USA in the foreseeable future. However if the plant has an efficiency of 35%, the fuel cost could rise to $2.8/GJ. It should be possible to deliver an energy crop for this price in the USA today but the energy conversion efficiency required is only currently available with co-firing.

These estimates apply to the USA and even there they can only offer broad guidance. However it seems probable that co-firing could deliver power at a competitive price today in some parts of the world whereas dedicated biomass power plants will not be able to compete effectively without some form of incentive.

Solar Stirling Engine Basics Explained

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
