The Viura natural gas field is situated beneath the Autonomous Community of La Rioja, some 12 kilometres from Logroño, with proven reserves of 1 bcm. The complex has been in commercial operation since the end of January 2015, having been commissioned by Unión Fenosa Gas as operator in consortium with two other companies. The complex uses traditional methods to extract natural gas then conditions it at the processing plant before it is injected into the Enagás national gas transmission grid.

The Viura field is a geological structure dating back to the Cretaceous period, more than 100 million years ago, made up of sedimentary sandstone whose pores house natural gas at a depth of some 4,000 metres. Since that era, layer on layer of clay have been deposited on top of the porous sandstone, forming a perfect seal to maintain the water tightness of this field.

It is estimated that this field contains at least a proven volume of 1 bcm (or 1 billion cubic metres of natural gas), but there is a possibility that the porous rock could house even larger amounts. This proven volume would be the equivalent of five years supply at current consumption levels for the whole of La Rioja. Read more…

Allison Transmission dedicated Sept. 25, the first day of “Truck Emotion,” to a Ride & Drive at the F1 Monza Circuit to demonstrate the outstanding performance of natural gas vehicles (CNG and LNG) fitted with Allison fully automatic transmissions. Leading European OEMs discussed the advantages of Allison-equipped, alternative-fuel vehicles – from ease of use, comfort and safety to reduced fuel consumption and emissions.

European fleet representatives in the distribution and refuse industries attended the event.  Presenters included Antonio Bravo, machinery department director at FCC Environment, a European leader in public waste and resource management, operating in 35 countries. In his presentation, “Application of Natural Gas in Urban Vehicles for Environmental Services,” Bravo shared FCC’s considerable experience with Allison-equipped CNG vehicles, noting they currently have over 1000 trucks in operation. Renault D-Wide

“At FCC, we first fitted an Allison transmission on one of our refuse trucks back in 1990,” said Bravo. “After realizing the economic advantages for a fleet as large as ours, we began using Allison Automatics in all of our refuse trucks. We strongly believe in this technology, and in the last few years, we also have been fitting Allison transmissions on our waste-bin washers, tankers and skip loaders,” he said.

According to Bravo, the economic, environmental and safety benefits Allison Transmission’s technology delivers are “crystal clear.” “Without a manual clutch, the maintenance costs decrease dramatically; Allison’s controlled acceleration reduces emissions and noise pollution; and safety increases together with driving comfort,” he said.Allison-fitted Volvo at the test-drive

OEMs including Iveco, Renault, Volvo and Scania made Allison-equipped CNG vehicles available for the Ride & Drive following the workshop. CNG day guests were able to experience the benefits discussed during the morning’s workshop firsthand in a variety of vehicles, including a Scania G340 tractor on the Formula 1 Circuit.The Scania on Monza's circuit

In the afternoon, industry media joined the Ride & Drive and interviewed some of the participating fleet managers. Among Allison’s international guests, was the French group Fraikin, a European leader in industrial and commercial vehicle rental, with 175 branches in Europe and approximately 650M euro in annual sales volume. The company owns about 100 Allison transmissions fitted on medium- and heavy-duty trucks, according to Remi Paing, project manager at Fraikin.

Chandon pointed out that natural gas engines in heavy trucks are relatively Allison Standsmall, compared to diesel models, which can raise valid concerns among fleet managers regarding startability and power. Since Allison has been supplying Iveco with fully automatic transmissions featuring Continuous Power Technology™ for the last 15 years, responsiveness in Allison-equipped alternative-fuel vehicles is not a concern at Iveco.

Duro Felguera (DF), in a 50/50 consortium with Elecnor, has won the tender called by the Comisión Federal de Electricidad (the Federal Electricity Commission or CFE in Spanish) in Mexico to build the Empalme II combined cycle power plant in the State of Sonora. The project is for 397 million dollars, equivalent to 349.3 million Euros. The deadline for delivery is estimated at 30 months.

According to the contract terms, signed at the close of business on Friday 23 October in Mexico City, the capacity of the Empalme II plant will be roughly 790 MW, and it will be gas-fired. There will be two gas turbogenerator units, two heat recovery boilers with three pressure levels and a steam turbine. The cooling system will be simple and will employ seawater. The plant will be connected to a 400 kW substation.

According to CFE, the purpose of the facility is to meet the growing demand for electricity in the north-west of the country.

Mexico is the country where DF has delivered most projects in Latin America, mainly in the field of energy. The power installed is almost 4,500 MW. Since 1998 the company has collaborated in the delivery of combined cycle, open cycle and cogeneration power plants with technologists such as Westinghouse, Siemens and Alstom Power.

DF’s first steps in Mexico in the field of energy were taken in 1998 in projects that the group had contracted by means of its subsidiaries Felguera Montajes y Mantenimiento and Mompresa, for the installation of turbomachinery. Both companies had previous experience in Colombia and started work in Mexico with the electromechanical assembly at the 150MW open cycle power plants of El Sauz, Hermosillo and Huinalá.

These projects were delivered to Westinghouse and followed by the full electromechanical assembly of recovery boilers at the combined cycle plants of Monterrey I, II and III, and Hermosillo, and for the full electromechanical assembly of the Rosarito plant, this time for the multinational ABB Alstom Power, and in larger facilities. In the first decade of the 21st century, the company was contracted by Siemens-Westinghouse to deliver the majority of the work at the open cycle plants of El Sauz II and El Encino: preparing the land, civil works, supplying the balance of plant equipment, the complete electromechanical assembly and commissioning.

These experiences enabled DF to keep on working in the country, with practically the whole assembly of the power plants of Valle de México, Naco Nogales, San Lorenzo and Tuxpan, in some cases almost 350 MW. In addition to the work on all these gas-fired power plants, in 2003 and 2004 the company delivered an EPC turnkey project for a cogeneration plant within the Pemex petrochemical Pajaritos plant, located in Veracruz. In this case DF took on the whole project, from the engineering to commissioning: 39 MW and 180 tons of steam per hour. Almost ten years later, Mompresa built further cogeneration plants in Mexico: one for the paper manufacturer Biopappel in Veracruz, and another for the textile company Kaltex Fibers in Altamira.

Apart from the energy field, DF has also worked on projects on Mexico for the petrochemical, iron and steel, cement and bulk handling sectors, for clients as important as Pemex, Cemex and Altos Hornos de México.

Siemens will provide H-class power plant technology to Mexico yet again. The equipment will be installed in the new combined cycle power plant 298 CC Valle de México II.

The natural-gas-fired power plant will have an installed capacity of 615 megawatts and will be located in the municipality of Acolman. The customer is a consortium consisting of Cobra Instalaciones y Servicios and Initec Energía from Spain, and Avanzia Instalaciones from Mexico that will build the plant on an EPC basis. The three companies belong to Spanish Construction and Services Group ACS. Commercial operation is scheduled for December 2017.

Siemens will supply two SGT6-8000H gas turbines, one SST6-5000 steam turbine, three SGen-1000A generators as well as the SPPA-T3000 control system for the turbines. Additionally, Siemens will supply the auxiliary equipment, materials, spare parts and special tools, as well as TFA onsite engineering support.

The gas turbines, generators and the steam turbine will be produced in the Siemens Charlotte gas turbine manufacturing plant in North Carolina in the United States.

Siemens has sold 74 H-class gas turbines and is now present in the world’s biggest energy markets: North and South America, Asia, Europe, and Africa. The fleet of Siemens H-class world-record gas turbines has achieved more than 3,700 starts and more than 160,000 fired hours. In May this year Siemens has been awarded a contract to supply two SGT6-8000H gas turbines and two generators to Mexico. The components are to be installed at the Empalme I Combined Cycle Power Plant (CCPP) in Sonora, Mexico.

Wärtsilä has been contracted to supply a major Flexicycle power plant to Energía del Pacífico S.A. in Acajutla, El Salvador. It will be the largest and most efficient power plant in El Salvador, and the first in Central America to be fired by LNG-based natural gas. The 378 MW installation will feed electricity to the national grid.

The order is estimated to be included in Wärtsilä’s order book in 2016, and the plant completion is scheduled for 2018. The value of the order is approximately EUR 240 million.

As of today, about 50 percent of the 1600 MW generation capacity in El Salvador is based on oil. The new power station will decrease the price of electricity because the fuel, LNG-based natural gas, is cheaper than oil. Natural gas also produces 30 percent less carbon emissions and 99 percent less sulphur dioxide emissions than oil.

The power plant will be the first in Central America to run on LNG-based natural gas. A dedicated LNG import terminal will be built at the same location.

The power plant will comprise nineteen Wärtsilä 50SG engines and a combined cycle steam turbine, producing high fuel efficiency of close to 50 percent. The Dry Flexicycle technology with a closed loop cooling system requires zero water consumption, which is a major benefit in El Salvador which has recently suffered from the worst droughts in 40 years.

Wärtsilä’s installed capacity in Central America and the Caribbean is approximately 4800 MW, and globally 58 GW.

Natural gas is a fossil fuel, but not a petroleum product. Due to its composition, which is essentially methane (CH4), it is a very light gas when it is released, rising into the atmosphere and dissipating, thus eliminating the risk of accumulations at ground level. Natural gas also offers a renewable alternative via biogas/biomethane that is still the same chemical product – methane gas – but is produced from the fermentation of biomass of any type. Valdemingómez in Madrid is home to Europe’s largest biomethane plant from solid urban waste that every year injects into the grid an amount of biomethane gas equal to the consumption of Madrid’s 450 refuse trucks all of which run off compressed natural gas (CNG).

As it is the hydrocarbon with the simplest molecule, it offers very clean combustion with significant environmental advantages. Apart from almost entirely eliminating the emission of particles and NOx, the emission of NO2, which is the NOx component used to measure air quality in cities, completely disappears. It is thus a paradox that the sharp fall in NOx that has taken place in diesel engines from €1 to €5 has resulted in all NOx being NO2, leading to an increase in the specific emission of NO2.

This is one of the reasons for alarm bells ringing in Madrid in January because of NO2 and during the end of July due to high levels of troposphere ozone, a secondary contaminant caused by the effect of the sun on NOx and others elements of the air we breathe. CNG in urban fleets is helping improve the air quality of our cities and this is why it will end up becoming the urban fuel of choice. Read more…

Axpo Iberia S.L. has decided to strengthen its presence in the Portuguese energy market by acquiring 25% of the share capital of Goldenergy, a company belonging to the Grupo Dourogás which has a current portfolio of more than 250,000 customers to which it supplies electricity and natural gas within different consumption categories: industry, services and the domestic market. Present in several areas of Portugal, Goldenergy has been selling natural gas and electricity on the Portuguese market since May 2008 and directly and indirectly provides employment for around 400 workers.

Following the liberalisation of the Portuguese natural gas market, which took place in recent years, Goldenergy has posted notable growth in consumers’ transition from the regulated market to the free market. It currently has a 23% market share in terms of the number of customers in the domestic gas consumption sector on the liberalised market and it believes that there are still opportunities for growth. Axpo is therefore the ideal shareholder to provide the financial soundness and experience needed.

To date, Axpo has had a limited presence in the Portuguese market with a market share of around 1.3%, very much based on supplying energy to industrial customers spanning practically all lines of business. This transaction will decidedly strengthen its activity in Portugal and it will take on new markets with lower consumption customers, SMEs and even domestic consumers.

The agreement was arranged in Lisbon on 30 july between Nuno Afonso Moreira, CEO from Golden-ergy, and Ignacio Soneira, CEO at Axpo Iberia, S.L. “Following this transaction, Goldenergy will be able to benefit from Axpo’s international experience, experience with wholesale energy markets and its risk management. Its financial robustness will be key in financing our plans for growth and together we will be able to improve both companies’ positions in the Iberian market”, Nuno Afonso Moreira com-mented.

Ignacio Soneira stated after concluding the agreement: “Until now, Axpo Iberia’s presence in Portugal was limited to the large and medium customer segments and with this transaction we are taking a major step towards entering into a new segment such as domestic gas and electricity customers. This represents a highly attractive challenge and an opportunity to learn and continue to grow in other markets and segments”.

This agreement is subject to approval by the authorities regulating the market, and it is forecast to come into effect in October. Following the share investment, Goldenergy’s management team will stay intact, and so will the business structure and employment positions.

Since it entered the Iberian market in 2002, Axpo Iberia has gradually expanded its lines of business in Spain and Portugal. It currently covers a wide range of services: electricity and gas sales; energy management for special system producers; Operation and control power generation centres (CECOGEL in Spanish); structured products and electricity, biomass and CO2 trading.

No-one can deny the fact that CHP is one of the most efficient ways of generating power. To name but a few of its advantages, it helps reduce natural gas consumption and the energy bill; by being generating at the points of consumption there are no losses from its distribution; it strengthens the security of the energy supply; it increases the competitiveness of those industries that use it; it creates jobs and contributes to the industrialisation of the country. And these are not its only benefits. So why are we letting it die out?

There are many reasons to defend CHP as a technology that we cannot do without as it generates electrical energy and heat. The above benefits are the most obvious; they are those that would feature in any efficient energy generation manual. But they are not alone.

In 1990, the Member States of the European Union undertook that, by 2020, they would reduce greenhouse gas emissions by 20%; increase the presence of renewables by 20%; and bring down the consumption of energy by 20% through increased energy efficiency. The majority of the States are, to a lesser or greater extent, complying with the first two objectives. However, both globally and individually, we are a long way from achieving the 20% energy saving target. Read more…

Today, gensets with biodiesel- or natural gas-powered engines, are one of the most widely-used technologies in the distributed generation market, whether for emergency applications, prime or continuous power, CHP and so on. The global market keeps on growing and in line with two reports published by Navigant Research, global installed capacity in diesel gensets could grow from 62.5 GW in 2015 to 103.7 GW in 2024. Natural gas gensets are forecast to grow from 12.9 GW in 2015 to over 27.1 GW in 2024. Despite the predominance of diesel gensets, the line between both is increasingly blurred given the growing popularity of dual-fuel diesel-gas gensets. This article covers some of the main conclusions of these reports.

Reciprocating engines represent the most widespread and mature technology for any type of energy generation, from small portable gensets to larger industrial engines that power generators of several megawatts. Reciprocating engine-based gensets can be grouped together to form power plants, even though their primary use is for distributed generation.

As a source of emergency, continuous or prime power, diesel gensets have historically been the most popular for energy generation applications, in almost any power range and are positioned to continue this steady growth in most regions and power classes. Read more…

At the World Gas Conference in Paris last month, Chevron chief executive John Watson highlighted the need for investors and stakeholders in prospective liquefied natural gas (LNG) projects to remain focused on the long-term goals ahead, warning them not to defer new developments due the anticipated wave of cheap United States LNG. New business models are required, he remarked, to keep alive the next wave of projects that would be needed to serve the rise in global demand for gas over the next decade.

The significant majority of this new demand will come from Asia, and from emerging economies seeking to develop gas and LNG infrastructure. Although a recent International Energy Agency (IEA) report highlighted the need for gas to make itself more competitive with other fuel sources, tightening markets are forecasted not to last long as demand is again likely to outstrip supply beyond 2020 – with much of this rising demand coming from new Asian markets.

Critical in the goals to continue developing new gas and LNG infrastructure – and to repel short-term investor wobbles – will be placing natural gas at the forefront of Asia’s drives to reduce air pollution, reduce carbon emissions and further expand gas as a transportation fuel – onshore and offshore. Major suppliers now look firmly to Asia for positive momentum and the uptake of new sources of gas and LNG supply, thus fuelling confidence in new projects and ensuring demand growth will continue to be met beyond 2025.

In line with focusing business in this region, the world’s leading investors, stakeholders and players in gas and LNG will gather in Singapore this October. Facilitating and driving these business discussions and connections is the Gastech Conference & Exhibition, which will arrive in Singapore from 27 to 30 October 2015, coinciding with Singapore’s Golden Jubilee.

The event’s four day conference programme features a wealth of C-level executives representing key investor, procurement and supplier interests. Truly reflective of the regional shift, the opening plenary sessions on Tuesday 27 October focus on connecting global suppliers with key Asian consumers, with leadership confirmed from CNOOC Gas & Power, JERA (Chubu-TEPCO), Tokyo Gas Company, CPC Taiwan, KOGAS, IE Singapore, Pavilion Energy, Chevron, ExxonMobil, RasGas/Qatar Petroleum, ENGIE, and more.

Highlighting more specific commercial and technical aspects, the remaining three days of the conference will address 10 highly-relevant topics: gas market outlook, future use of gas and LNG in the Asian fuel mix, contracting, pricing and trading, LNG projects: non-technical risks and deliver, application of innovative technology, shipping, gas as a transport fuel, health, safety, security and environment, emerging gas market developments and investment, and FLNG innovation with containment and storage.

With Singapore at the heart of Asia’s drive for economic prosperity and its government’s regional ambitions in gas and LNG trade, Gastech will provide attendees an insight into regional and global opportunities, and a unique and first-hand outlook of the city state’s overseas energy investment plans. The opportunities for those working in gas and LNG to develop new business and new markets are unprecedented, with the focus firmly on the role Asia will play in leading the ongoing growth of gas and LNG, through key business development, partnerships and deal-brokering.

Gastech Conference & Exhibition is hosted by BG Group. The event is also supported by the Energy Market Authority (EMA) Singapore, International Enterprise (IE) Singapore and the Singapore Exhibition & Convention Bureau (SECB), and will be held in association with the Singapore International Energy Week (SIEW).
