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.

SECU-Box for Better utilization of Load Capacity

The forest products company Stora Enso is one of Sweden’s major users of transportation services, incessantly moving timber from remote forests to small-town pulp mills, and finished paper products to markets at home and abroad. Basic geographical realities make truck transportation the only practical solution for much of this transportation, but the company ships by train when possible—for both...

Flameless Combustion Cuts Air Pollution

Catalytic combustion, in which volatile organic compounds (VOCs) are oxidized by using a catalyst to promote the burning process, has been around for many years. The process is an effective way to cut VOC pollution, but practical applications have been limited to gaseous fuels. Now the Swedish company Zemission is preparing to introduce a product that will make catalytic...

Any Car Can Be Emission-free

The zero-emission car has long been seen as a distant dream, but a Swedish company is making the dream a reality. Many people still equate electric cars with flimsy plastic boxes that fall far short of the standards we’re used to in passenger cars. Energy efficiency and sustainability are strong arguments for a certain segment of the buying public,...

Trucks Take the Train to Reduce Climate Impact

The Swedish province of Jämtland is so sparsely populated that trees outnumber inhabitants. Approximately half of the region is covered in forest and built up areas constitute a mere one percent. It’s not surprising that many Swedes associate Jämtland with outdoor sports and camping. But there are also plenty of talented business minds, with numerous small companies and an...

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...
