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 gasoline offered nationwide. The directive is a component of a bigger effort to extend the biofuels mix, which not solely contributes to cleaner air, but in addition leads to decrease gasoline costs on the pump.
The DOE Round No. 2024-05-0014 issued in Could requires all downstream oil business contributors to implement a 3-percent CME mix beginning Oct. 1, 2024, and progressively growing the proportion to 4 % in 2025, and 5 % in 2026. I wrote about this welcome information earlier in a column titled, “Cleaner air, cooler planet with biofuels” (5/30/24). You may 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 lowering ranges of particulates, carbon monoxide, and hydrocarbons in diesel-powered automobiles, biodiesel contributes to combating local weather change and environmental air pollution. The mandated mix of three % is decrease than the biodiesel mix being offered in the USA, Germany, and a few European nations, as diesel in these areas is being blended with ester at a share of 5 to twenty %. This comparability relies on a examine by the Philippine Coconut Authority (PCA) and the Division of Agriculture (DA). (You may entry the examine 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 automobiles have been fed with one hundred pc CME, findings confirmed that it will be “technically viable to substitute petroleum diesel with CME, however not economically viable as a result of excessive value of CNO (coconut oil).” Nonetheless, the passage of Republic Act No. 8749, or the Philippine Clear Air Act in 1999, supplied an impetus to develop CME as a diesel gasoline additive to assist the transport sector adjust to the smoke emission requirements set by the regulation.
The Biodiesel Improvement Challenge, which took off in Could 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 examine 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 mean discount of 20 % in NOx (nitrogen oxides) and even higher, a 70-percent discount in particulate matter, was recorded. A better CME mix of 5 % additionally leads to a 10-percent enhance in mileage, similar to an estimated web financial savings of P4.17 per liter of diesel, in response to the DOE.

Electrical automobiles. After all, the greener choice is to modify to electrical automobiles (EVs), which have decrease emissions and produce fewer heat-trapping greenhouse gases. In the USA, EVs are all of the sudden changing 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 automobiles,” The New York Instances (NYT) reported on June 3.
The $7,500 federal tax credit, along with different state incentives, are a further incentive for purchasing new electrical automobiles, though they’re nonetheless costlier than gasoline automotive fashions, the NYT added. Within the absence of considerable subsidies from the Philippine authorities, we are able to select plug-in hybrid electrical automobiles that make the most of batteries to energy their electrical motors, whereas utilizing gasoline similar to gasoline to energy their inside combustion engines. Probably the most accessible choice, nonetheless, is using biofuels similar to biodiesel and ethanol mixing in gasoline gasoline as they assist cut back the carbon footprint of conventional combustion engine-powered automobiles.
Carbon neutrality. The Biofuels Act of 2006 mandates that each one liquid fuels for motors and engines offered within the nation be blended with biofuels, that are different gasoline sources made out of biomass. When burned, they produce fewer emissions of particulate matter, sulfur dioxide, and different poisonous air pollution similar to these emitted by fossil fuels (oil, coal, and pure fuel). Using biofuels is a step in the proper course 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 will require a life-style change from all of us. To restrict world warming, web zero (or carbon neutrality) requires that each one emissions of heat-trapping greenhouse gases be counterbalanced by the discount of fossil gasoline use in equal quantities.
To make this a actuality, each authorities and personal sectors ought to pursue huge investments in “zero-carbon” renewable sources, together with wind, photo voltaic, biomass, hydropower, and geothermal.
