This document discusses using liquid carbon dioxide as an alternative to water for hydraulic fracturing in shale gas extraction in India. The objective is enhanced gas recovery from Indian shales while sequestering the greenhouse gas carbon dioxide. Methods suggested include flooding experiments to model methane desorption and carbon dioxide adsorption capacities of Indian shale basins based on their total organic content. Previous works demonstrated that organic matter preferentially adsorbs carbon dioxide over methane, and that imaging techniques can provide insights into shale microstructure and flow properties. The conclusion is that using carbon dioxide for fracturing and sequestration could make shale gas extraction more sustainable while providing economic storage of carbon dioxide.

Strategies for the Success of Nuclear Powered Commercial Shippingwww.thiiink.com
ABSTRACT
The development of nuclear powered commercial ships has taken on greater
importance beyond transporting cargo cheaper. Increasing limitations on Sulfur Oxide
emissions from ships has put the global maritime industry on a search for economical
ways to meet current and future environmental regulations. With the inevitable
development of trans-Arctic shipping, nuclear power is the only means of preventing the
phenomenon of “graying of the ice”, which is the deposition of black carbon soot
particles on snow and ice from oil and natural gas burning engines, leading to increased
heat retention and melting. However, unless these next generation nuclear powered
ships are cost-effective and can achieve an acceptable level of safety, they will not be
deployed and their environmental advantages not realized. This paper discusses in
qualitative terms methods for the cost-effective and safe development of nuclear
powered commercial ships for world trade, specifically by a United States initiated
program. Discussed are changes to the nuclear regulatory model that can alleviate
certain economic burdens that ship-sized nuclear reactors may face, and
recommendations are made for how industry can actively lower nuclear power’s high
upfront costs. Emphasis is placed on the development of an inherently safe, widemarket
application reactor that can achieve these cost and safety goals.
The document discusses how Naval Surface Warfare Center Philadelphia Division (NSWCPD) engineers are experimenting with augmented reality (AR) technology to improve shipboard damage control. Specifically, they are working to develop a heads-up display for helmets using the Microsoft HoloLens that would allow sailors to see clearly through smoke and access compartment information. This AR technology could overlay a virtual 3D model of the space on the sailor's view, helping them navigate safely. NSWCPD hopes to integrate AR with their current work in areas like 3D modeling and improve shipboard maintenance and repair assistance. They are in the early stages of research but see potential for AR to enhance damage control and engineering support.

Introduction
SUPPORTERS ARGUE
There is no proven case of hydrofracking contaminating drinking water, and the process is perfectly safe. Natural gas can revive local economies, reduce U.S. dependence on foreign oil, and provide a cleaner-burning fossil fuel. Further regulation is unnecessary and will only prevent an opportunity for the United States to develop an alternative energy source and create jobs.
OPPONENTS ARGUE
The chemicals used in fracking fluid are toxic and pose a danger to public health if they contaminate drinking water reserves or leak out of wells. Oil and gas companies are not being honest with the public about the dangers of hydrofracking, and the federal government should apply much stricter, nationwide regulations to ensure that hydrofracking does not cause widespread health problems that could plague the public for generations.
Issues and Controversies: Hydrofracking Workers

Many observers have hailed natural gas as a solution to several energy problems facing the U.S. Utilizing the country's ample domestic supply of the resource, many have said, could greatly decrease U.S. dependence on foreign oil and possibly drive energy prices down. Furthermore, natural gas produces much less carbon dioxide than other fossil fuels, about half as much as coal, making it the cleanest burning fossil fuel available. Energy experts have also touted natural gas as a cheap alternative to renewable energy sources, such as wind or solar energy, until engineers devise a way to make renewable energy more cost efficient. According to the Department of Energy, natural gas already produces about one-fifth of the nation's electricity, a proportion that may increase as energy firms tap more domestic reserves of natural gas.
The Marcellus Shale, a 95,000-square-mile geologic formation deep underground that stretches from West Virginia through Pennsylvania to upstate New York, is estimated to contain as much as 500 trillion cubic feet of natural gas. In order to access the natural gas in the Marcellus Shale and other shale formations, however, energy companies have to employ a controversial procedure called hydraulic fracturing—also known as "hydrofracking" or simply "fracking." Hydrofracking is a technique that releases natural gas by pumping millions of gallons of water, laced with sand and chemicals, thousands of feet underground to blast open, or fracture, shale formations, freeing the gas.

1) Gas hydrate reservoirs can be characterized using well logs such as resistivity and acoustic logs to determine gas hydrate saturation. More advanced logs like NMR provide insights into pore-scale distribution and reservoir properties.
2) Studies including the Mount Elbert well in Alaska utilized logs like NMR alongside cores and pressure testing to understand gas hydrate occurrence in sediments and obtain properties like porosity, saturation, and permeability.
3) NMR can estimate fluid volumes like free water, clay-bound water, and gas hydrate saturation when combined with density logs, providing a more accurate understanding of gas hydrate reservoirs compared to resistivity alone.

A ROGUE CLIMATE EXPERIMENT OUTRAGES SCIENTISTS
A California businessman chartered a fishing boat in July, loaded it with 100 tons of iron dust and cruised through Pacific waters off western Canada, spewing his cargo into the sea in an ecological experiment that has outraged scientists and government officials. The entrepreneur, whose foray came to light only this week, even duped the National Oceanic and Atmospheric Administration in the United States into lending him ocean-monitoring buoys for the project. Canada's environment ministry says it is investigating the experiment, which was carried out with no government or scientific oversight. A spokesman said the ministry had warned the venture in advance that its plan would violate international agreements.
Marine scientists and other experts have assailed the experiment as unscientific, irresponsible and probably in violation of those agreements, which are intended to prevent tampering with ocean ecosystems under the guise of trying to fight the effects of climate change. Though the environmental impact of the foray could well prove minimal, scientists said, it raises the specter of what they have long feared: rogue field experiments that might unintentionally put the environment at risk.
The entrepreneur, Russ George, calling it a "state-of-the-art study," said his team scattered iron dust several hundred miles west of the islands of Haida Gwaii, in northern British Columbia, in exchange for $2.5 million from a native Canadian group. The iron spawned the growth of enormous amounts of plankton, which Mr. George, a former fisheries and forestry worker, said might allow the project to meet one of its goals: aiding the recovery of the local salmon fishery for the native Haida.
Plankton absorbs carbon dioxide, the predominant greenhouse gas, and settles deep in the ocean when it dies, sequestering carbon. The Haida had hoped that by burying carbon, they could also sell so-called carbon offset credits to companies and make money. Iron fertilization is contentious because it is associated with geoengineering, a set of proposed strategies for counteracting global warming through the deliberate manipulation of the environment. Many experts have argued that scientists should be researching such geoengineering techniques — like spewing compounds into the atmosphere to reflect more sunlight or using sophisticated machines to remove carbon dioxide from the air. But tampering with the environment is risky, they say, so any experiments must be carried out responsibly and transparently, with the involvement of the scientific community and proper governance.

A ROGUE CLIMATE EXPERIMENT OUTRAGES SCIENTISTS
A California businessman chartered a fishing boat in July, loaded it with 100 tons of iron dust and cruised through Pacific waters off western Canada, spewing his cargo into the sea in an ecological experiment that has outraged scientists and government officials. The entrepreneur, whose foray came to light only this week, even duped the National Oceanic and Atmospheric Administration in the United States into lending him ocean-monitoring buoys for the project. Canada's environment ministry says it is investigating the experiment, which was carried out with no government or scientific oversight. A spokesman said the ministry had warned the venture in advance that its plan would violate international agreements.
Marine scientists and other experts have assailed the experiment as unscientific, irresponsible and probably in violation of those agreements, which are intended to prevent tampering with ocean ecosystems under the guise of trying to fight the effects of climate change. Though the environmental impact of the foray could well prove minimal, scientists said, it raises the specter of what they have long feared: rogue field experiments that might unintentionally put the environment at risk.
The entrepreneur, Russ George, calling it a "state-of-the-art study," said his team scattered iron dust several hundred miles west of the islands of Haida Gwaii, in northern British Columbia, in exchange for $2.5 million from a native Canadian group. The iron spawned the growth of enormous amounts of plankton, which Mr. George, a former fisheries and forestry worker, said might allow the project to meet one of its goals: aiding the recovery of the local salmon fishery for the native Haida.
Plankton absorbs carbon dioxide, the predominant greenhouse gas, and settles deep in the ocean when it dies, sequestering carbon. The Haida had hoped that by burying carbon, they could also sell so-called carbon offset credits to companies and make money. Iron fertilization is contentious because it is associated with geoengineering, a set of proposed strategies for counteracting global warming through the deliberate manipulation of the environment. Many experts have argued that scientists should be researching such geoengineering techniques — like spewing compounds into the atmosphere to reflect more sunlight or using sophisticated machines to remove carbon dioxide from the air. But tampering with the environment is risky, they say, so any experiments must be carried out responsibly and transparently, with the involvement of the scientific community and proper governance.

Investigating the implications of a new-build hybrid power system for RoRo ca...Janie Ling Chin
This document summarizes a study that used life cycle assessment to evaluate the environmental impacts of a proposed hybrid power system for roll-on/roll-off cargo ships from manufacturing to end of life, compared to a conventional power system. The study estimated resource usage, emissions, and impacts and identified operating diesel generators and disposing of metallic scrap as particularly significant processes. It verified the environmental benefits of the hybrid system in most impact categories.

Navy researchers say they have developed a "game changing technology" for creating fuel from
seawater - a process that could keep ships out at sea longer.
The U.S. Naval Research Laboratory's (NRL) Materials Science and Technology Division announced
Monday that it had already flown a radio-controlled replica of a World War II plane using
hydrocarbon fuel made from seawater.
The fuel is created with the help of an electrolytic cation exchange module, a machine which
2. removes carbon dioxide from seawater while simultaneously producing hydrogen. The gases are
then formed into liquid hydrocarbons by a metal catalyst in a reactor system, the lab said in a
statement.
"In close collaboration with the Office of Naval Research P38 Naval Reserve program, NRL has
developed a game changing technology for extracting, simultaneously, CO2 and H2 from seawater,"
said Dr. Heather Willauer, an NRL research chemist. "This is the first time technology of this nature
has been demonstrated with the potential for transition, from the laboratory, to full-scale
commercial implementation."
Fuel produced this way would cost an estimated $3-6 per gallon, the NRL says, and could be
commercially viable within the next seven to ten years with proper funding and partnerships.
"Pursuing remote land-based options would be the first step towards a future sea-based solution,"
the NRL said in a statement.
The laboratory, which is based in Washington, D.C., focuses on overcoming technological challenges
that the Navy faces.
