Sustainable Biofuels For A Cleaner Environment

Do you know that when oil and gas are burned to fuel vehicles it creates so much contribution to pollution? Transportation contributes 30 percent to climate change as a result of pollution. It is just about time that we rethink how we fuel our modes of transportation. By using biofuels and biodiesels manufactured from organic materials such as corn and switchgrass, we can decrease the number of hazardous emissions from vehicle engines.

While the whole world is working to bridge the gap among nations through the English language by encouraging English courses like the Bakirkoy English Course (bakırköy ingilizce kursu), programs to clean the growing issue of pollution. The Natural Resources Defense Council (NCR) pushes the use of biofuels that are sustainable, protect landscapes, and decrease pollution throughout their lifecycle. The NCR is working at the federal and state levels to build benefits for clean fuels. They had been working also with the aviation industry as well as other large purchasers to make sure they actually buy biofuels.

The California State Low Carbon Fuel Standards

The NRDC has also helped layout and approve the California State low-carbon fuel standards that provide benefits to engine fuel producers, including corn ethanol and gasoline, to lessen the carbon depth of fuels distributed in the state. Carbon pollution is being computed from the standard extraction, refining, and combustion. This enables the company to escape from fouling fuels like tar sands. The California standard expects a rise in the use of alternative fuels in the field of transportation and energy by 2020 and even triple in percentage use by 2025. Together with other oil-saving and carbon-reduction steps, the California standard may help reduce consumer fuel costs by roughly $1,000 for every home by the year 2022. That is approximately a total financial savings of $50 billion.

Many oil companies have battled the cause of low-carbon fuel use. They filed lawsuits and launched ad campaigns which delayed the proposal and implementation of low-carbon fuel use. Along with other allies in the industry, the NDRC fought to defend the cause in court. They’ve documented the many health advantages of lowering tailpipe pollution. The coalition of leaders in the business and health industry help win the case.

Pushing Sustainable Biofuels In The Midst Of Industrialization

The NDRC is working to make sure that the developing industry for biofuels is sourced by genuinely clean materials. Huge fuel purchasers may find it difficult assessing if biofuels are made sustainably or in fact eliminate wildlife environment and boost carbon exhausts. NRDC analyzes certification courses to ensure they effectively measure carbon cutbacks, forestry influences, and wildlife dangers throughout the whole biofuels lifecycle. They give attention to the aviation market since it is a major customer that is prone to depend on liquid fuels for a number of years. The council launched a Biofuel Sustainability Scorecard for the Aviation business that measures successes of airlines in acquiring sustainably produced biofuels. Obtaining the market to invest in 100 % accredited sustainable biofuels can inspire sellers to begin providing the clearest fuels.

SCR: How It Works

With SCR or Selective Catalytic Reduction, the nitrogen oxide (NOx) reduction process takes place after combustion – so as to not diminish engine performance.

The process is simple: diesel exhaust fluid (DEF) is sprayed into the hot exhaust gases. The fluid consists of urea and deionized water. This mixture passes through a catalytic chamber.

When the hot exhaust combines with the DEF within the catalytic chamber, the exhaust is broken down into harmless nitrogen and water vapor – two natural components of the air we breathe.

The bottom line with EGR is it adds cost, complexity, hotter running performance and increased engine noise.
Fleets were slow to adopt yet another technology especially after the impact of the EGR engines that reduced fuel mileage and added maintenance cost. In 2010 US fleets had reached a 20-year high in vehicle age at approximately 6.9 years. But, now they are ordering new SCR vehicles and they are growing rapidly. There were approximately 400 SCR equipped Class 8 vehicles at the end of 2012. Effective the first of this year 2013 100% of all diesel on-road vehicles are utilizing SCR technology.

Why Tata Motors is offering both EGR and SCR in BS IV trucks and buses?

Tata Motors, the country’s largest truck and bus manufacturer, announced readiness of SCR (Selective Catalytic Reduction) and EGR (Exhaust Gas Recirculation) technologies for BSIV compliant engines, powering its range of Commercial Vehicles.

Exhaust Gas Recirculation (EGR) technology adopted by Tata Motors in 2010 will continue to power small-to-medium category of commercial vehicles with engine power requirements up to 180HP. EGR helps toreduce NOx emissions from the engine. Additionally, Tata Motors has adopted the globally proven SCR technology since 2014 for its Medium and Heavy-Duty Commercial vehicles ranging from 130HP to 400HP. Tata Cummins Ltd, a JV between Tata Motors and US-based Cummins Inc. has developed these engines. SCR technology allows engine to operate at more optimal combustion temperature providing better power, fuel efficiency and lower NOx and particulate matter generation.
