Underground gas storage : an introduction and UK perspective
No full textRising demand and the depletion of its offshore reserves has resulted in the UK becoming a net importer of natural gas. An increased reliance on imports and limited current storage availability mean that the UK faces increasing energy bills and risk of disruption to supply. Because of this the UK government has set about ensuring security of energy supply. Steps taken include the construction of major new pipelines from Norway and Holland and improvements to interconnectors in the southern North Sea. The Government also recognizes that improvements to the gas supply infrastructure are required, including the need for significant increases in gas storage capacity; best met by the construction of underground storage facilities. Focus on energy security has also raised the likelihood of a new generation of coal-fired power-stations. For such a step to be environmentally viable, clean-coal technologies with near-zero greenhouse gas emissions will be required. Underground CO2 storage will be a key element of this strategy. This volume reviews the technologies and issues involved in the underground storage of natural gas and CO2, by means of case-studies and examples from the UK and also from overseas. The potential for underground storage of other gases such as hydrogen, or compressed air linked to renewable sources is also reviewed

No full textHere is a curious book. Its title-page declares "The Artist's Book of Fables" but its pre-title-page has "Fables, Original and Selected, with a Memoir of the Author." After that title-page, it is identical with "Fables, Original and Selected" as in our copy printed by John Murray in 1833. There is again an AI at the front and an index of engravings and engravers at the back. I found that copy twenty years ago. I had found an inferior copy twenty-two years before that. At that time, I noted Aesopic fables here including "Stone Broth" and "The Mouse and the Oyster."This is a hardbound book (hard cover)James Northcote, R.A
A review of underground fuel storage problems and putting risk into perspective with other areas of the energy supply chain
Get PDFThe UK became a net importer of gas during 2004 and faces an increasing dependency on imports, yet has very little gas storage capacity. The UKs capacity to import, transport and store gas and liquid natural gas (LNG) has to be improved, requiring greater investment in new gas supply infrastructure. Construction of appropriately sited onshore underground gas storage (UGS) facilities is needed. However, local groups oppose most proposed UGS sites on the grounds of safety, citing the dangers of gas migration and rare fatal events, mostly in America.
This paper summarizes 228 reported events of widely varying cause, nature and severity at underground fuel storage (UFS) facilities; the majority at USA SPR facilities. Since UGS was first undertaken in 1915, reports of 13 fatalities, around 72 injured and the evacuation of at least 6700 people are found at UFS sites. Some communities have experienced multiple evacuations. In the context of the danger posed to the general public, three of those killed were staff at two UFS facilities. UGS (including LPG) has led to 10 civilian deaths, 25 injured and c. 1250 evacuated.
In other areas of the energy supply chain, casualties are orders of magnitude greater, with at least 1525 dead, 6826 injured and the evacuation of over 7000 at incidents involving above ground fuel storage tanks since 1951. When considering UK UGS applications, the risk of UGS and wider UFS experiences should be put into context. Worldwide, over 90 years experience in UGS now exists, with around 630 facilities of different types currently operational. Technologies used are often those of, or derived from, a well-regulated oil and gas exploration industry. In contrast to public perception, industry and academia recognize that UGS has an excellent health, safety and environmental record. Although it should not be claimed that gas will never be found outside the intended well or storage facility area, UFS casualty figures appear to corroborate claims by supporters of the technologies that salt caverns provide one of the safest answers to the problem of storing large amounts of hydrocarbons and that even in urban areas underground gas storage, oil and gas production can be conducted safely if proper procedures are followed. If gas is found outside the intended system, then after recognition of the problem, mitigation and safe operating procedures can and have been developed
Room temperature formation of rhodium nanoparticles on TiO<sub>2</sub> 110 via metalorganic chemical-vapour deposition (MOCVD) of [Rh(CO)<sub>2</sub>Cl]<sub>2</sub>
No full textRoom temperature adsorption of [Rh(CO)2Cl]2 on TiO2[110] is investigated using Scanning Tunnelling Microscopy (STM) which reveals the formation of nanoparticles that coexist with the mono-disperse Rh(CO)2Cl species; the spatial distribution of these particles indicates that nanoparticle formation occurs principally at step edges
Titania surface structures for directed growth of metal nanoparticles via metal vapour deposition and metal organic chemical vapour deposition
No full textIn this paper metal vapour deposition and metal organic chemical vapour deposition have been used to produce nanoscale metal particles on various TiO2(110) surfaces. The nanoparticles (Pd and Rh) are imaged directly by scanning tunnelling microscopy at ambient and elevated temperature in ultra high vacuum. The surface reconstruction of the TiO2 to a cross-linked (1 x 2) is used to form highly corrugated rectangular arrays that direct the growth of the Pd clusters. Thermal annealing at first induces a flattening and then a sintering of the nanoparticles. Ultimately the particles form a wide distribution of shapes and sizes. A crystal displaying crystallographic shear planes, composed of a self assembled array of alternating up-down step edges on the terrace, is used to direct the growth of Rh nanoparticles from [Rh(CO)(2)Cl](2). The particles are shown to grow mainly at the top edge of each step that runs at an angle to the principal directions of the surface
A review of onshore UK salt deposits and their potential for underground gas storage
Get PDFThe UK faces a major change in the nature of its gas supply as North Sea production declines and the country becomes increasingly reliant upon gas imports. As a result the UK Government recognizes that significant investment in gas supply infrastructure is required to maintain security of supply and manage the gas market. Part of that infrastructure will be additional underground gas storage capacity in specially designed and engineered salt caverns. This paper summarizes the distribution and nature of halite (rock salt) deposits in England and Northern Ireland, and reviews the details of existing and planned storage sites in salt caverns. There is considerable potential for further salt cavern development. However, not all of the UK salt fields are suitable, with the halite beds being too shallow, thin or impure
