2010-05-03 Pathways to Renewable Transport Fuels

I and Dr Richard Pearson were invited to a meeting held by Air Fuel Synthesis. In connection with this, I produced a roundup of renewable fuel plants in Europe, finding seven, and synthetic renewable fuel activities in the USA, finding two.

2013-11-01 Nuclear Power's Fatal Flaws

I had produced a 73-page study 'The Real Lessons of Fukushima', dated 2012-04-11, based on the evidence from over 230 references. This showed the crucial importance of 'decay heat' – an inherent characteristic of nuclear fission – in the event of a 'Loss of Cooling Accident' (LOCA). It also showed that the probability of a LOCA was unknowable, as the chains of events number billions, each requiring data on reliability, and failures could lead to catastrophic radioactive releases to air, land and sea. So nuclear disasters are inevitable, as the record shows.

2013-06-07 The Consequences of Major Nuclear Releases

The consequences of the Chernobyl and Fukushima nuclear releases are horrendous. Yet the 'worst-case' nuclear releases are 100 times greater, with far worse consequences.

2010-05-03 The CRI Renewable Methanol Process and Potential

The Icelandic company Carbon Recycling International has developed a process for synthesising methanol from renewable sources. The feedstocks are hydrogen produced by the electrolysis of water with geothermal and hydro electricity and carbon dioxide captured from geothermal hot water boreholes.

2018-10-23 The EU has spent nearly $500 million on technology to fight climate change—with little to show for it

In a report to be published later today, the European Court of Auditors will say that the EU spent more than €424 million ($486 million) over the past decade decade fruitlessly trying to establish carbon-capture technology. The EU considers the technology crucial to hit its climate goals, which will require the union’s member states to reach net-zero emissions within decades.

2017-07-10 Climate and Energy Topics

Topic 1) emphasises the urgency of energy transition.

Topic 2) is the main focus of the document, with the paper by Sgouridis et al, 2016.
This identifies the relationship between the remaining fossil fuel emissions cap, the transition time, and the required investment in Renewable Energy (RE) supply plant.

Topics 3) and 4) refer to the initial conditions prior to the energy transition.

Topic 5) compares the Energy Return on Investments (EROIs) of Renewable Energy (solar and wind power) supply measures with the weighted average value of 20 assumed by Sgouridis et al.
Topic 6 is concerned with the global limits of renewable power sources.
Where Topics 3) and 4) deal in UK quantities, Topic 6) deals in Global quantities. However, the UK must expect to use only a proportionate share - e.g. equal per capita.

Topics 7) and 8) consider energy demand measures as complements of the supply measures assumed by Sgouridis et al. They refer to two papers by Cullen and Allwood et al, 2010 and 2010.
Including energy demand measures will greatly ease an energy transition within the constraints, such as 2 C global warming.


2012-04-11 The Real Lessons of Fukushima

The Real Lessons of Fukushima - click for full size image
This study is based on evidence on the Fukushima disaster and it's consequences, almost all from the internet. Many quantitative studies have been found, but no proper studies from the IAEA or the UK ONR. The fast-moving and highly dangerous events of such a disaster require decision support. Thermal models of the reactors and spent fuel pools are essential to predict their behaviour under Station Blackout and to evaluate possible counter-measures. Also plume (dispersion) models of possible radioactive releases are essential to inform decisions on the magnitude and direction of evacuations. The Japanese have such a plume model, but it was ignored until later. Also they had no instrument for airborne radioactivity measurements at hand and had to rely initially on aerial surveys carried out by the Japan-based US Emergency Response Centers. These deficiencies were omitted or downplayed in the reports of the IAEA Fact Finding Mission, but most were included in the report of the Hatamura Panel.
