Ground & Water Source Heat Pumps – Royal Festival Hall

This article below is incorrect, given that water source heat pumps have been used in Britain since 1945, with the Royal Festival Hall in London being heated by a heat pump taking heat from the River Thames in 1951.: Excerpt from David Banks, Introduction to Thermogeology: Ground source heating and cooling. Second Edition, Blackwell (2012) ” […]

Commission to clarify guidance for energy

By Dave Keating – European Voices, 17 October 2013 Wide range of approaches across the EU http://www.europeanvoice.com/article/imported/commission-to-clarify-state-aid-rules-for-energy-/78442.aspx The European Commission’s energy department is expected to publish next week draft guideance on subsidies for renwable energy, to bring greater clarity and predictability to member states’ approaches. But data showing that fossil fuels and nuclear energy together […]

Pentland Firth – Nick Balmer

This was written as a comment to: http://rspa.royalsocietypublishing.org/content/469/2157/20130072.full A few years ago I was working for BAM Nuttall pricing renewable energy projects including offshore windfarms. We became part of a consortium looking at the possibility of installing wave or tidal current turbines in the Pentland Firth. It was one of the most interesting projects that […]

Australian idea for ammonia transmission of wind energy

https://mail.google.com/mail/?shva=1#inbox/1384c714ccc80b76 takes you to mail with file attached… ——– Original Message ——- I am wondering if you all might be interested in a proposal I am pushing in Australia that might also be relevant to other places with renewable energy resources in remote areas such as in North Africa, the Middle East, desert areas in China […]

wind turbine kW input when the wind isn't blowing, maximum output capacity, annual load factor and the

Dear Claverton, Below is a table of the complete fleet of eastern Australian wind turbines showing the maximum output capacity, annual load factor and the kW input when the wind isn’t blowing. Some farms apparently have their own auxiliary power and don’t draw from the grid but in any event the drain on the grid […]

CCE-SJG Gasproducer System TAR FREE Gasifiers for electricity generation and / or heat applications

We are the manufacturers / suppliers of the unique CCE-SJG Gasproducer System and currently only produce four types of TAR FREE Gasifiers for electricity generation and / or heat applications in the following ranges: 1. A 120 Nm³/h, with a max output of 50kVA/ 40kWe (120kWe), or 180kWth 2. A 180 Nm³/h, with a […]

Are large thermal stores and Combined Heat and Power District Heating (CHP) with District Heating (DH) pipes to deliver heat to buildings is more likely to be a better solution to de carbonising the building heating sector than relying on large-scale electricity storage of renewable or nuclear electricity (the “all electric solution”) delivered to buildings via cable?

One of the most intractable energy problems in Europe is how to deal with the heating load of buildings, (11 EJ/y), which is the largest user of primary energy and is presently met largely with gas. This heat load will not go away due to the expense of insulating the legacy buildings beyond quite modest […]
