Greenhouse gas emissions from domestic hot water: heat pumps compared to most commonly used systems

Abstract

We estimate the emissions of the two most important greenhouse gasses (GHG), carbon dioxide (CO2) and methane (CH4), from the use of modern high-efficiency heat pump water heaters compared to the most commonly used domestic hot water systems: natural gas storage tanks, tankless natural [...]

University of Texas study underestimates national methane emissions at natural gas production sites due to instrument sensor failure

Abstract

The University of Texas reported on a campaign to measure methane (CH4) emissions from United States natural gas (NG) production sites as part of an improved national inventory. Unfortunately, their study appears to have systematically underestimated emissions. They used the Bacharach [...]

A bridge to nowhere: methane emissions and the greenhouse gas footprint of natural gas

Abstract

In April 2011, we published the first peer-reviewed analysis of the greenhouse gas footprint (GHG) of shale gas, concluding that the climate impact of shale gas may be worse than that of other fossil fuels such as coal and oil because of methane emissions. We noted the poor quality [...]

Engineering evaluation of direct methane to methanol conversion

Abstract

Investigations into direct methane to methanol conversion are justified based on the avoidance of synthesis gas generation, which accounts for around 60% of the capital cost of synthesis gas to methanol conversion. A significant body of information already exists on the process chemistry, [...]

Assessment of plug-in natural gas versus electric vehicles on the Groningen energy network

Abstract

This study aims to evaluate the effect in the energy network of a big shared of decarbonise vehicles (NGV and EV) based on car-use profiles of current conventional and electric vehicles in the city of Groningen. Charging profiles were developed within CBS dataset of mobility and transport, [...]

Natural Gas Transmission Pipelines: Risks and Remedies for Host Communities

Abstract

Transmission pipelines deliver natural gas to consumers around the world for the production of heat, electricity, and organic chemicals. In the United States, 2.56 million miles (4.12 million km) of pipelines carry natural gas to more than 75 million customers. With the benefits of [...]

The economic implications of natural gas infrastructure investment

Abstract

Since 2001, the Indonesian government has issued natural gas master plans annually holding the planned gas infrastructure developments in order to motivate private parties who are not motivated due to the lack of the gas infrastructure increase. Since 2002, there were only three segments [...]

New Challenges for the Russian Energy Industry

Abstract

Currently many sectors of the Russian economy, including the fuel and energy sector, are undergoing structural changes. This is due both to the energy transformation (a significant change in the structure of the energy balance) and the recent events of 2022. The article analyzes how these changes will affect the Russian energy sector. Firstly, the risks of reducing natural gas exports to the EU countries are assessed. Gas supplies to the EU are a significant part of Russia's export earnings, and the supplies themselves are difficult to redirect to other directions. Secondly, it is analyzed how recent changes will affect the development of the energy sector using the example of two scenarios for the development of the energy industry before and after 2022. Finally, it is assessed how the changes that have taken place will affect the effectiveness of an active climate policy in Russia. The possibility of a reduction in domestic demand for gas in the EU or an increase in production is unlikely. However, an increase in LNG (liquefied natural gas) imports is possible, which may allow the EU to abandon natural gas imports from Russia in the coming years. EU nominal regasification capacity allows for a potential increase in EU LNG imports by 110 billion cubic meters per year. This can be done both by redirecting supplies from other countries to the EU, and by increasing production and liquefaction of LNG. As a result of an increased sanctions pressure, with a high degree of probability, without an active climate policy, the level of greenhouse gas emissions will increase significantly. In addition to climate effects and associated negative environmental impact, this also negatively affects the prospects for economic development. Thus, greater consumption of fossil fuels makes the economy more dependent on their prices and reduces the potential for an increase in the volume of export. An analysis of decarbonization scenarios has shown that because of the recent events, an active climate policy will cost more, with more modest results.

The volatility of natural gas prices - Structural shocks and influencing factors

Abstract

The paper examines the primary drivers and factors influencing the volatility of natural gas prices in the world from January 2007 to July 2020. In addition to the narrow dependence between crude oil and natural gas prices, the influence of renewable energy production and coal [...]
