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.

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.

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.

New fuels and accompanying hikes in ticket prices will be essential to clean up air travel and avoid the worst effects of climate change, according to a new report.
Aviation is responsible for 5 per cent of global warming, and it is on track to power through a quarter of the planet’s annual carbon budget by 2050.
Despite some fledgling efforts to develop electric aircraft for short-haul flights, air travel is proving one of the most difficult sectors to decarbonise.In its analysis, European green transport group Transport and Environment (T&E) found that replacing fossil fuels in planes with “electrofuels” is the “only technically viable solution that would allow aviation to exist in a world that avoids catastrophic climate change”.
This will present a challenge to consumers as well as the industry, as the expense of these fuels means the cost of a plane ticket is projected to rise 58 per cent if they replace kerosene in all aircraft.

“The good news is that radically cleaner aviation is possible even with today’s technology,” said Andrew Murphy, aviation manager at T&E.
“Getting to zero starts with properly pricing flying and progressively increasing the use of sustainable synthetic fuels.
“There is a cost to this, but in light of how cheap subsidised air travel has become, and the incalculable cost of runaway climate change, it’s a price worth paying.”


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.
