Advances in wellbore integrity

 CO2 storage relies on the injection of the gas either via pre-existing wellbores or, in the future, new wells. CO2 is potentially corrosive and in certain conditions can induce rapid cooling. Both conditions are detrimental to wellbores so it's important to understand how these conditions occur and what mitigation options are available. The G...

Opening Speech GHGT-13 Kelly Thambimuthu

 As I spoke to open GHGT-13 today COP22 is underway in Marrakech. It is worth reflecting on the historic agreement that was made at the preceding COP21 meeting held in Paris last year. Paris set us the added aspiration of a new global temperature target of below 20C, even though we are working towards a 20C target. We know very well that even ...

Pressure Testing Experiment at the Swiss Mont Terri Rock Laboratory

 The Swiss are making an important commitment to long-term CO2 storage through international collaboration and research. This is notably evident at the Mont Terri Rock Laboratory situated in the Jura Mountains about two hours drive north of Lausanne. This facility has been deliberately constructed within an impermeable shale called the Opalinu...

The use of natural analogues to study patterns of CO2 migration.

 The geomechanics session at GHGT-13 in Lausanne has covered a variety of topics including the value of studying natural analogues. Useful insights into CO2 migration within formations can be gained especially where fractures provide natural conduits for geochemical alteration. Exposures of the Jurassic Entrada formation in Utah provide an exc...

“Keep calm and carry on” - COP-22 underway, with CCS events, and American developments.

COP-22 got underway in Marrakesh in unseasonable heavy rain. Several thousand delegates are gathering at the tented city that is the conference centre for the work to start developing the implementation details of the Paris Agreement, in terms of frameworks, processes and mechanisms. Negotiations commenced under SBSTA on the Technology Framework in...

New IEAGHG Report: 2016-13 Fault Permeability

Fault zones are widely recognised as being important to the secure long term storage of CO2 as they could provide a leakage pathway out of the target reservoir. Fault characterisation within reservoirs, especially where they extend into caprock, and other overlying formations, needs to be thoroughly understood as part of any risk assessment for CO2...

New IEAGHG report: Evaluation of process control strategies for normal, flexible and upset operation conditions of CO2 post combustion capture processes

 It is important for power plants to be able to operate flexibly to respond to changes in consumer demand for electricity. Flexibility is also becoming increasingly important due to the greater use of other low carbon generation technologies, particularly variable renewable generators. The issue of operating flexibility of power plants with ca...

Regional Assessments of the Economic Barriers to CO2 Enhanced Oil Recovery in the North Sea, Russia and GCC States

 The use of CO2 for enhanced oil recovery (EOR) is a well established commercial practice in the United States where it has been used for over 40 years. There is widespread potential for CO2-EOR in other mature petroleum producing regions. If CO2-EOR could be implemented it would offer an economic stimulus to develop CO2 storage. There are, ho...

Visit to Tomakomai Project

 During the CSLF week of meetings in Tokyo, the Japanese hosts RITE and JCCS Company arranged for a day visit to the Tomakomai project on the northern island of Hokkaido. This project is capturing CO2 from a gas stream from the hydrogen production unit at the Tomakomai refinery using a unique two-stage pressure swing absorption system, and inj...

Paris Agreement Enters into Force.

The Paris Agreement has now entered into force. To date 74 countries have joined the agreement, 55 were needed. These countries represent 58.83% of global greenhouse emissions, breaking the required 55% threshold. That was the easy bit, now the hard work starts, there a big hill to climb to get to below 2 degree C temperature rise.

Climate Scientists say 1.5C is inevitable.

 In a recently published paper called "The Truth about Climate Change", a group of climate scientists tell us that, "By 2015, the global temperature had risen by 1°C above pre-industrial levels, that it is certain to rise another half a degree by 2030 and will continue to rise to 2°C by 2050 unless drastic action is taken to reduce emissions" ...

Ratification of Paris Agreement moves closer.

 According to the UNFCCC as of today (23rd September 2016) 62 countries representing 49.3% of global CO2 emissions have now ratified the Paris Agreement. To enter into force the agreement needs 50 countries representing 55% of global emissions to sign. So milestone one has been passed and milestone 2 is close to being achieved. At a single eve...

Keeping up Momentum on HFC reduction.

 The Montreal Protocol is expected in October 2016 to agree an amendment to phase down HFC emissions. Ahead of that decision the US Government has this week hosted a meeting with over 100 delegates who called for securing an ambitious amendment with an "early freeze date". The freeze date is the year when countries stop increasing the producti...

China and USA Ratify Paris Agreement

 At the G20 meeting in Japan China and the USA have both announced their intention to ratify the Paris Agreement. This means that he two biggest emitters of greenhouse gases have committed themselves to the principle of moving to a temperature target of below 2 degrees centigrade. Both countries have now formally lodged their instruments of ra...

Global Warming started in 1830’s

 New research led by Australian scientists, and recently published in the journal Nature suggests human impacts had begun to change the climate as back as the 1830's, earlier than previously expected. Their conclusions were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice ...

If we didn’t know already, 2015 was the hottest year on record.

 The 2015 State of the Climate report has recently been published in the Bulletin of the American Meteorological Society. The report confirmed that 2015 surpassed 2014 as the warmest year since at least the mid-to-late 19th century. The record heat resulted from the combined influence of long-term global warming and one of the strongest El Niñ...
