Here is a a story I wrote for the Finnish company Wärtsilä recently: Emissions from ocean-going ships are now being investigated and discussed in public, and there is a demand for stricter regulations. While land industries and other transport forms have been widely regulated during the last decades in order to limit the emission, the ocean transports have been ignored. This might be due to the fact that shipping takes place on the high seas away from populations who can readily see impacts of emissions has been part of the reason the industry’s fuel standards lagging behind other industries.

Alkylated gasoline is a newer type of gasoline on the Danish market, it is branded as “green gasoline”. It is not, but it has advantages to traditional gasoline. The new type of fuel is directed to smaller engines typically used in private gardens, but it also has a history of use in high performance sport engines.
The gasoline, which is technically called ‘alkylated gasoline’, are cleaner than traditional gasoline, Soder less and gives a more complete combustion. It is an advantage for those who use tools with internal combustion engines, such as garden tractors or chain saws. Alkylated gasoline is storage stable and does not change, although it has been stored in a cold tank all winter long. Conventional petrol contains reactive substances that can get gasoline to oxygenation, and thus reduced quality already after few weeks of storage.
“Everybody knows the situation where you have to start a chain saw or lawn mower in the spring and the motor has difficulty to jump in again. It is often caused by petrol. With alkylated gasoline the problem is partly solved. Alkylate gasoline is the cleanest fuel that can be produced at a petroleum refinery, “says Steenbuch, Product Manager at Bauhaus, who now sells the alkylated gasoline brand Aspen.
Aspen is among a few special refineries to produce alkylate. Gasoline has in recent years been taking off as consumers’ environmental awareness and greater emphasis on the interaction between the engines and fuel quality.
“It is quite natural for us to present alkylate gasoline for our environmentally conscious consumers. First and foremost, we have a green policy that applies to all our product lines. In addition, we have for many years had various types of oil on the shelves, primarily for our motorized garden tools, “says Steenbuch. Read the rest of this entry »

Recently I visited a heating system in the Danish city of Svendborg. A new double gas boiler should in future keep city residents warm - and it happens to a plant which promises more than 100 percent efficiency.
“We have an efficiency of currently more than 100 percent. It sounds crazy, but it is actually possible, when we simultaneously make use the heat from the collected fluid, which is a byproduct of flaring, “said Ove Andersen, who is head of Svendborg plant. He points out that the extensive surveillance of the facility has made it easy to fine tune production, according to what is most effective. For example, it appears that the best answer is to have two boilers running at partial strength, rather than to have one boiler running at full strength. Such observations are used to get the maximum out of the facility both economically and environmentally.
The advanced mechanics and monitoring of the new plant has been developed and delivered by Weishaupt and Lemvigh-Müller.

I just read about a new type of solar based water heaters for households, that are already on the market. The setup is pretty much the same as with normal solar water heaters. There are panels for absorbing solar heat, a pump and a an indoor tank for accumulation. But with this type, there is no water circulating. Instead the system uses gas that will boil at a temperature about 0 degrees. The gas will then be transported inside to a compressor and this will create a temperature at about 100 degrees. The pump and compressor uses a minimum of electricity - far less than the popular ground- air- or lake heating system.
The amazing thing about this setup is that:

I just came across this Canadian invention that lets you reuse the thermal energy from your shower. The great thing about is that is so simple and it is has no moving parts meaning no energy consumption. The downside is that it has to be build in with your drain. This is on my list for my future house. Check it out at http://www.ecodrain.ca/
The cold water that you usually mix with the hot water gets heated by the used water. This increases the efficiency of the water heater by 25%-40%, says ecodrain.

I am in the market for a new car. To my surprise there is no alternatives in Denmark to gasoline and diesel cars. It is possible to order a Prius, but no dealers has a model home I can test. It is also possible to import a hybrid, electric or plantoil/biodiesel ready car but theres is not one single place in this country I can go and see and have a spin in such a car.
Importing a car is a difficult task, there will be doubt about the tax until the car is imported and I would prefer to have a local salesman to address for service and if something goes wrong.
I do not understand why this is. All major car manufacturers have electric cars, hybrid and plant oil ready cars and they are on the market in several countries, why not here? Why do they not test the Danish market - they would find me and possible a lot of others potential buyers.
Some months ago the tax on new cars were differentiated, so it makes environment friendly cars a lot cheaper. This is said to have increased the sale of small gasoline cars - but so far no new products have been introduced. Thats a shame, now I’ll buy a Hummer instead…

Japan was the largest producer of solar power until Germany exceeded it in 2005. European countries have been expanding their production of solar power more rapidly than Japan. Germany now accounts for 39 percent of total production, while Japan’s contribution is 38 percent. Germany, which will host the summit meeting on global warming in June, has a reputation for being environmentally conscious, and subsidies for solar power have been increased, with the stable price of such power helping to make solar power generation more popular. However, in Japan, subsidized projects by the New Energy Foundation, aimed at generating solar power for private residents ended in fiscal 2005, and now only local governments have subsidized projects.

Google.org – the philanthropic arm of Google - yesterday lauched an exciting project that offers a glimpse of a smarter energy future: cars that plug into an electric grid powered by solar energy. Plug-in hybrid electric vehicles can quadruple the fuel economy of the average car on the road today. As Google.org demonstrated at yesterday’s event, plug-in hybrids can sell power back to the electric grid when it’s needed most through vehicle-to-grid (V2G) technology
Google.org’s core missions is to address climate change. In the U.S., transportation contributes about one-third of all greenhouse gas emissions –- with more than 60 percent of those emissions coming from personal vehicles. By accelerating the adoption of plug-in hybrids and vehicle-to-grid (”V2G”) technologies, this new project, RechargeIT.org, aims to reduce emissions and dependence on oil while promoting clean energy technologies and increasing consumer choice. Linking the U.S. transportation system to the electricity grid maximizes the efficiency of our energy system. From these efforts, we believe the environment will benefit - and consumers will have more choices to fuel their cars.viagra anxiety Does Medicaid Cover Viagra Kentucky taking viagra woman

China announced yesterday it had made a breakthrough in excavating natural gas hydrate, the so-called “flammable ice”, which is believed to be a potential natural energy source. Zhang Hongtao, deputy director-general of China Geological Survey (CGS), said gas hydrate samples were successfully collected from the northern part of the South China Sea last month. China is the fourth country after the United States, Japan and India to make such a technological achievement. Zhang said the development was expected to ease the country’s dependence on oil and coal. Initial estimates indicate the potential volume of gas hydrates around continental slopes in the area exceeds 100 million tons of oil equivalent, Zhang said. The samples were collected from two different stations in the Shenhu (Magic Fox) continental slope on May 1 and May 15, he said. Nicknamed “flammable ice”, gas hydrates are crystalline solids, which occur when water molecules form a cage-like structure around smaller “guest molecules” of methane, ethane, carbon dioxide and other substances. Stable only at low temperatures and/or high pressures, gas hydrates are extremely fragile, and mainly exist either in the seafloor or below tundra at high latitudes. The resource has become a hotspot of international research in recent decades, as scientists believe gas hydrates are a perfect alternative fuel resource to oil and gas, writes China Daily.
