Comments Off on Smelly but smart: ships to use ammonia as "zero-carbon" fuel

While the world rushes against time to curb carbon emissions from cars, trains and airplanes, another area of transport raises concerns. Today, almost  90% of all goods traded globally are transported by water . As massive fuel guzzlers compared to other transportation methods, ships exacerbate the emissions problem. To deal with the issue of carbon pollution by ships, several companies and organizations are exploring ammonia as a possible solution.  In 2008, the International Maritime Organization(IMO) set a target of halving its emissions by 2050. To accomplish this, IMO intends to use ammonia as a fossil fuel alternative. Ammonia makes a great alternative since it does not contain carbon; the pungent-smelling gas can burn within an engine and power it without emitting carbon dioxide. Due to ammonia’s ability to provide clean energy, several companies are now testing the gas as an alternative fuel. A German company, Man Energy Solutions, has announced plans to install an ammonia-ready engine on a ship. According to the company, the first model will be dual, allowing the ship to run on traditional gas with an ammonia option. Meanwhile, Eidesvik, a Norway-based company, plans to invest in ammonia-powered ships. By 2023, the company will install ammonia-powered cells on all its ships. Similar to batteries, these cells will generate energy to power the ship’s motor. Though ammonia is less energy-rich than many other marine fuels, it proves more energy-dense than hydrogen . Hydrogen, another zero-emission gas, has been used to power cars, trains and planes. While cheaper to produce than ammonia, hydrogen presents handling difficulties due to its -253 degrees Celcius storage temperature. “Ammonia sits very nicely in the middle,” Dr. Tristan Smith of University College London said. “It’s not too expensive to store and not too expensive to produce.”  If the shipping industry adopts ammonia as a fuel source, there is still more work required to keep it clean. Ammonia produces nitrogen oxides, which can be toxic. Fortunately, there is a technology that can purify the oxides before they are released.  + BBC Image via Pexels

Solar-powered bubble shield focuses on physical distancing in public

Comments Off on Solar-powered bubble shield focuses on physical distancing in public

As of May 5, more than 3.5 million people in 215 countries around the world have been infected with the novel coronavirus , according to the World Health Organization . While the world continues to socially distance, designers and creatives are beginning to imagine different ways to protect people from the virus; case in point, this futuristic bubble shield by DesignLibero. Amid the COVID-19 pandemic, Milan-based DesignLibero has imagined a product that brings a whole new meaning to personal space. The team has released a concept for the “bubble shield” to provide wearers with a private, protective barrier for public spaces. According to the designers, the clear, inflatable plastic dome will let users walk around in public without coming into contact with germ-filled droplets or pollution . Related: 6 ways to save energy while sheltering in place So how would this bubble shield work? The designers imagined a way to go in public without worrying about microparticles of the coronavirus or even air pollution. In addition to its anti-pollution and anti-virus properties, the shield would run on solar energy thanks to a built-in set of flower-shaped, flexible solar panels on top of the plastic dome. The solar energy would fuel a fan coil and air pump to maintain an air supply and cool the inside of the bubble. The conceptual barrier would be made using thermic-welded ETFE , a type of fluorine-based polymer material. The battery pack in the backpack is used to inflate the microstructure and acts as a power supply for the air pump compressor and fan coils. Interchangeable filters are designed to purify the air inside the bubble. There are two separate halves attached together with an easy-open zipper so that wearers can simply step in and out of the bubble to use it. + DesignLibero Images via DesignLibero

Investors Ask the Bank of England to Ditch Carbon-Heavy Investments

Comments Off on Investors Ask the Bank of England to Ditch Carbon-Heavy Investments

Investors, environmental groups and academics sent a letter to the  Bank of England ( which is responsible for keeping England’s economic stability ) this week urging it to assess the risk that carbon intensive investments in the United Kingdom have on citizens and investors alike. Five of the 10 largest companies in the U.K.’s benchmark stock index, the FTSE 100, are high carbon companies and the group addressing the letter believes that puts the U.K. at risk financially. The authors of the letter argue that depending on finite, unsustainable resources for investing while the world moves into renewable technology is untenable and poses a threat to everyone affected by investments in those companies.
