TRANSPORTATION

Transportation causes significant environmental impacts – not least in the form of carbon dioxide emissions – but the development of improved vehicles, components and fuels is moving ahead quickly. Impacts can be moderated by everything from energy-optimized driving habits to hybrid engine technology and even ambitious proposals for far-reaching infrastructure upgrades.

The Smarter Electric Grid

Electric grids in most developed countries are engineered around centralized production from large hydropower installations, nuclear generators or combined heat-electric plants. These systems are designed for efficient production and distribution of electricity. Power generation is determined by projected demand, and when shortfalls occur reserve generators are brought online. But the electricity we use in the future will need to...

Reduced Friction Saves Fuel

The chemical compound tungsten disulfide, developed in the 1960s for the American space agency NASA as a dry-film lubricant, has found a number of applications in aerospace and auto racing. Although it offers excellent friction protection with only a thin surface film, existing tungsten disulfide coating methods remain too complex and expensive for most large-scale industrial uses. But now...

Volvo and Vattenfall Announce Plug-in Hybrid Venture

The Swedish automaker Volvo and the power generation company Vattenfall have created a joint venture company to develop a plug-in hybrid vehicle that can run on both electricity and diesel fuel. The unique cooperation calls for Volvo to begin series production of the hybrid cars in 2012, with Vattenfall supplying infrastructure in the form of public charging stations and...

“Green box” cuts pollution

Fuel expenses constitute a substantial portion of the total cost of operation for commercial vehicles. Quite simply, reducing fuel consumption increases profits. At the same time, fossil fuel consumption releases large amounts of carbon dioxide, which is believed to be causing global warming. So there’s no shortage of good reasons to look for improved efficiency. Automobile and truck makers...

Patented “eco-rubber”

Where do all the old car tires go? Before answering that question, let’s take a look at the composition of modern rubber tires. Just under half of a tire consists of natural and synthetic polymers, the most common of which is styrene-butadiene rubber (SBR). Tires also contain carbon black, metal, textile weave, zinc oxide, sulphur and various additives. Composition...

High precision for environmental protection

Ship drive trains are traditionally constructed with five components assembled in a series: diesel engines, gearboxes, propeller axles, propellers and rudders. This arrangement leads to certain limitations in ship construction. Large diesel engines are generally optimised for a certain operating speed, set to match the ship’s intended cruising velocity. But many vessels, such as cruise liners and those that...

Reduced environmental impact with new technology

Swedish companies Scania and Volvo approach climate issues by developing more fuel-efficient engines, using alternative fuels and making their production ”carbon dioxide-neutral”. The companies also develop systems to help their customers plan their transports, as well as with driver training. A driver who drives 180,000 km per year can save SEK 60,000 per year in reduced fuel costs if...

Treetop taxi

The benefits of driving private automobiles are fantastic, but there are also downsides in the form of environmental impacts, highway congestion and parking shortages, especially in cities. But traditional mass transit also has disadvantages: trips may require several transfers and waits can be lengthy. Could SkyCab be the way to make the most of the benefits of both cars and buses, while...

Oil from Sweden is better for the environment

Fossil oil is of fundamental significance to a modern society, both as a source of energy and as a chemical raw material. Refined oil is used to produce a wide variety of products such as petrol, diesel, heating oil and tarmac. It also is an ingredient in plastics, fabrics, hygiene and beauty products. The availability of high-quality oil is...

The quest for environmentally-adapted fuels

An increasing number of consumers want to drive environmentally-adapted cars. In recent years, demand for fuels for various types of transport has grown significantly. Traditional vehicle manufacturers and oil companies have developed their traditional and new products with greater care for the environment in mind. Engines have been adapted to operate on biofuel and be more fuel-efficient, while petrol...
