Increased biodiesel mix: Countdown begins

It’s lower than a month earlier than the implementation of the Division of Vitality’s (DOE) order for a 3-percent coco methyl ester (CME) mix in all diesel gas offered nationwide. The directive is a component of a bigger effort to extend the biofuels mix, which not solely contributes to cleaner air, but additionally leads to decrease gas costs on the pump.

The DOE Round No. 2024-05-0014 issued in Might requires all downstream oil trade individuals to implement a 3-percent CME mix beginning Oct. 1, 2024, and regularly growing the proportion to 4 p.c in 2025, and 5 p.c in 2026. I wrote about this welcome information earlier in a column titled, “Cleaner air, cooler planet with biofuels” (5/30/24). You possibly can entry the column right here.

Allow us to take into account the advantages of utilizing biodiesel. First, when blended with diesel, CME, a fatty acid ester produced from coconut oil, turns into coco-biodiesel. By decreasing ranges of particulates, carbon monoxide, and hydrocarbons in diesel-powered autos, biodiesel contributes to combating local weather change and environmental air pollution. The mandated mix of three p.c is decrease than the biodiesel mix being offered in america, Germany, and a few European nations, as diesel in these areas is being blended with ester at a proportion of 5 to twenty p.c. This comparability relies on a research by the Philippine Coconut Authority (PCA) and the Division of Agriculture (DA). (You possibly can entry the research right here: https://tinyurl.com/jnsav7t3).

Substituting diesel with CME. In 1995, the PCA studied the method of transesterification, which converts fat into biodiesel. When diesel-powered transport autos have been fed with one hundred pc CME, findings confirmed that it might be “technically viable to substitute petroleum diesel with CME, however not economically viable because of the excessive value of CNO (coconut oil).” Nevertheless, the passage of Republic Act No. 8749, or the Philippine Clear Air Act in 1999, supplied an impetus to develop CME as a diesel gas additive to assist the transport sector adjust to the smoke emission requirements set by the legislation.

The Biodiesel Improvement Venture, which took off in Might 2001, demonstrated that with a 1-percent CME mix, a 50-percent discount in smoke emissions may very well be achieved with out engine modifications. A separate research by professors on the Technological College of the Philippines and Japan’s Nihon College on the engine efficiency and emission of a single-cylinder four-stroke diesel engine additional proved the viability of CME as a diesel additive for low-sulfur diesel. A median discount of 20 p.c in NOx (nitrogen oxides) and even higher, a 70-percent discount in particulate matter, was recorded. The next CME mix of 5 p.c additionally leads to a 10-percent enhance in mileage, comparable to an estimated web financial savings of P4.17 per liter of diesel, in keeping with the DOE.

Electrical vehicles. In fact, the greener possibility is to change to electrical autos (EVs), which have decrease emissions and produce fewer heat-trapping greenhouse gases. In america, EVs are instantly turning into extra reasonably priced to potential consumers. “Extra environment friendly manufacturing, falling battery prices, and intense competitors are decreasing sticker costs for battery-powered fashions to inside placing distance of gasoline vehicles,” The New York Occasions (NYT) reported on June 3.

The $7,500 federal tax credit, along with different state incentives, are a further incentive for purchasing new electrical vehicles, despite the fact that they’re nonetheless dearer than gasoline automobile fashions, the NYT added. Within the absence of considerable subsidies from the Philippine authorities, we are able to select plug-in hybrid electrical vehicles that make the most of batteries to energy their electrical motors, whereas utilizing gas akin to gasoline to energy their inner combustion engines. Essentially the most accessible possibility, nonetheless, is using biofuels akin to biodiesel and ethanol mixing in gasoline gas as they assist scale back the carbon footprint of conventional combustion engine-powered vehicles.

Carbon neutrality. The Biofuels Act of 2006 mandates that every one liquid fuels for motors and engines offered within the nation be blended with biofuels, that are different gas sources constituted of biomass. When burned, they produce fewer emissions of particulate matter, sulfur dioxide, and different poisonous air pollution akin to these emitted by fossil fuels (oil, coal, and pure gasoline). The usage of biofuels is a step in the best route towards the gradual decarbonization of our transportation sector. The objective of reaching “web zero emissions” by 2050 remains to be a great distance off as a result of it might require a way of life change from all of us. To restrict world warming, web zero (or carbon neutrality) requires that every one emissions of heat-trapping greenhouse gases be counterbalanced by the discount of fossil gas use in equal quantities.

To make this a actuality, each authorities and personal sectors ought to pursue large investments in “zero-carbon” renewable sources, together with wind, photo voltaic, biomass, hydropower, and geothermal.
