Dear Oliver, You’re not alone in your scepticism! However, you’re wrong about the CO2 emissions. The reality is that coal +CCS as currently defined/mandated emits significantly less CO2 than NG CCGT without CCS (‘unabated’), because authorities in the UK (and most countries except Japan) are demanding c.90% CO2 removal from coal, whereas CCGT emits about […]

"Electric power from offshore wind via synoptic-scale interconnection" – using HVDC interconnectors to smooth intermittent power
Abstract World wind power resources are abundant, but their utilization could be limited because wind fluctuates rather than providing steady power. We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected. Based on 5 yr of wind data from 11 meteorological stations, distributed […]

Limits to the costs of backup for variable generation
We have all the tools we need to manage wind penetrations to 70%, so it’s not a question of “if”, only of “which combination”. In this post, I explore some of the costs of those tools, and find a limit to those costs.
The Cogeneration or CHP Directive
This refers to the ”’Directive on the promotion of cogeneration based on a useful heat demand in the internal energy market and amending Directive 92/62/EEC”’, officially 2004/8/EC and popularly better known as the ‘CHP Directive’ It is a European Union directive for promoting the use of cogeneration in order to increase the energy efficiency and […]

They will be attempting to raise £20k for the charities Water Aid and NACC (National Association for Colitis and Crohn’s Disease). Any donations […]
Future Challenges for CHP in the UK and Continental Europe, F.Starr PhD, FIMMM, C. Eng : Feb 2010
Abstract: An objective, but broadly sympathetic, view has been taken of the future of cogeneration in the UK. Although its current problems, appear to have resulted from the market economy, the basis to these difficulties is structural. These arguments are supported by discussions on the electrical and CHP efficiencies of various prime movers. These include […]
Extract from Mailman transportation issues, trams, buses etc.
As more than one commentator has noted, we cannot convert our present motor vehicle fleet to non fossil liquid or gas fuels, because there is not enough bio-mass/arable land available, and internal combustion engines are very energy inefficient. Buses use a trivial amount of fuel compared to trucks and cars. Converting buses to run on electricity […]
