Countermeasures against Freon gas are delayed ③

Expand business opportunities related to CFC countermeasures Prof. Hideaki Nakane of Kochi University of Technology (environmental science) is important not only to strengthen the application of penalties, but also to develop CFC-less greenhouse effect and use of alternative substances. Although it is not a frontal penalty, the development of substitutes for each company is progressing. The development of refrigerant, foaming agents, and detergents using a completely different type of material is also underway. For example, a large commercial refrigerator for ammonia and refrigerant is considered the use of old-fashioned ammonia, there is toxicity and flammable ammonia, there is a problem in the use of household refrigerators, Instead, hydrocarbons such as propane and butane have been researched and developed. Hydrocarbon. It seems that there is no problem because the amount of filling is small in the refrigerator for the home though it is flammable. In Europe, household refrigerators that use hydrocarbons are quite popular. Japan manufacturers have started production and sales since 2002. The introduction of hydrocarbons into air conditioners is also under research and development. Sales have been started in the Germany. Although non-flammable carbon dioxide is an ideal refrigerant, there is a drawback that there is no refrigerant effect in the environment with high outside temperature. However, the research and development to use it for the car air conditioner advances. On the other hand, the MH refrigeration system which uses the property "The heat is discharged when the hydrogen is absorbed and the hydrogen is emitted, and absorbs the heat" of the hydrogen adsorption alloy of the refrigeration system which does not use the refrigerant is one of the attempts. In addition, the electronic device is systemized. A system that utilizes the Peltier effect of "heat transfer from one metal to the other metal when electricity is passed to the junction of two metals", the cooling of the processor of the computer and the small refrigerator of the hotel and the hospital because it is quiet It is already used for the refrigerator of the wine only. Hydrocarbon and carbon dioxide for the foaming agent, the conversion to water has been partially practical, for the propellant is converted to hydrocarbons (liquefied natural gas: LPG) except for special applications. Water or the like is used for the cleaning agent. Environmental business is a mission to improve the environmental impact of "century in the Environment" in the 21st century, the needs are just growing.

The 21st century is the era of hydrogen civilization 4 - mobile devices and methanol cartridge

4. Increased use of mobile devices.

The 21st century is said to be "the age of Hydrogen civilization" in the 21st century, and its efforts are accelerating toward that era. The core of the technology is the fuel cell (FC: FUELCELL). A fuel cell is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy.

Fuel cells that can be used for longer periods of time than conventional batteries used in mobile phones, personal computers, and other mobile devices have been developed by electrical products and telecommunication equipment manufacturers. I hear that demand is surged to come here with the expanding mobile device market. However, the method of reacting the air with methanol is common, and it is now a bottleneck that it is difficult to bring in the methanol cartridge of the hydrogen collection to the airplane etc. by terrorism measures. In Japan, a resource small country that relies on foreign countries for the majority of the hydrogen harvesting energy resources from non-fossil fuels, we can secure resource security if we can collect hydrogen from "water resources" and "biomass" which can be domestically and procured domestically. In Japan, it seems that the "Hydrogen society" spread is in accordance with the national interest above all. This country is at a turning point in its energy policy.

The 21st century is the era of hydrogen civilization 3 - the fuel cell car

Development of fuel cells and hydrogen vehicles. It is said that the fuel cell car which runs with the electric motor is the final form of the eco car, and Toyota and the car maker are rushing development. The government's target is 40,000 in total by 2020, while the current state remains at 1800 units. If there is a place to stick to the running of the internal combustion engine by gasoline than the motor running as a car company, or hydrogen vehicle equipped with an internal combustion engine with hydrogen fuel? In both of these, the expansion of hydrogen supply stations (currently 90 several places) is required. In the media fuss. The electric car that they recommended by that gone arrest is inevitable, and the fuel cell car will be in the spotlight instead.

The 21st century is the era of hydrogen civilization 2 - the ene farm

As an "ene farm", "Energy farm" refers to the spread of fuel cells for domestic use as a means of fuel cell for households, and the coinage is coined by "energies" and "farm = farms". To make electricity and heat from hydrogen and oxygen. In a word, it can be said that the farm products are made by water and the Earth. "Ene Farm" is like introducing a power plant to each home in a manner of speaking. Make your own energy. Power generation and its accompanying exhaust heat can be used for heat source such as hot water and heating and cooling. Gas and oil companies are focusing on the spread of fuel cell power generation businesses since the East Japan earthquake in Tepco. Currently, there is a background that hydrogen is not the most cost of gas and oil harvesting. Since 2009, the market is being formed in earnest. As of July, 2018, a quarter of the home fuel cells were introduced, and the demonstration test was cause overturn. At that time, three companies of ENEOS, Toshiba and Panasonic were competing, but now Panasonic has one company left. 　The price is cut by two million yen. If one million yen is cut, the penetration rate might accelerate at a dash. The subsidy for the introduction is organized every year. By the way, the fuel cost is reduced by five to six million yen per year.

The 21st century is the era of hydrogen civilization 1 - the fuel cell

The 21st century is said to be "the age of Hydrogen civilization" in the 21st century, and its efforts are accelerating toward that era. The core of the technology is the fuel cell (FC: FUELCELL). There are three flows depending on the application. One is stationary type for home and business use. The second is for automotive vehicles and is already attracting attention as a fuel cell vehicle. The third is for mobile devices such as laptops and mobile phones. I tried to chase the fuel cell technology innovation is rapid progress.

Eco-friendly hotels are on the increase 2

I hear that more and more tourists and young people in Japan choose environmentally friendly accommodations. The Eco-hotel, which is based on a different ecological service than the traditional service, is established as a new hotel service. In the past, it was an opportunity to acquire ISO14001 certification for each hotel and to improve the environment of business activities. 　I followed the current situation of the Eco Hotel. It is said that the environment and the health of the service Japan the various services of environmental consideration are considerably late compared with Europe and America. There are only seven hotel hotels that have been certified as "Eco Mark". However, unrelated accommodations are canned with public eco-mark certification. The accommodation is born in various places to catch the eco-trend and put the axis on sustainable management. In the hotel opened in the center of the city, a lot of greening area on the site, bed of use of the old materials, use of recycled bicycles, to reduce the food loss (devised to use an organic carrot without peeling the skin), etc. various. At the hotel in Kawasaki City, a disposable toothbrush such as a waste plastic is made into solid fuel, and it is said that it makes electricity with hydrogen taken out there, and covered about 30% of the power consumption of the hotel. Some of the guests said, "I want to support such management, or say the effort to devise the environment consideration in the place where there are a lot of guest lure in the price competition in the TV.
