High oil prices, competing demands between foods and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming of algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels. Algae can be efficienctly grown on land that is not suitable for agriculture and hold huge potential to provide a non-food, high-yield source of biodiesel, ethanol and hydrogen fuels. Several recent studies have pointed out that biofuel from microalgae has the potential to become a renewable, cost-effective alternative for fossil fuel with reduced impact on the environment and the world supply of staple foods, such as wheat, maize and sugar. What are Algae? Algae … Continue reading →
“The CO2 problem” has traditionally been understood as the fact that excessive CO2 produces global warming. But near the end of the 20th century, scientists started talking about a second CO2 problem, “ocean acidification”. Ocean acidification results from the fact that about 30 percent of our CO2 emissions have been absorbed by the ocean. This absorption keeps down the warming of the atmosphere that would otherwise be produced by these emissions. Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the … Continue reading →
Gulf Cooperation Council countries are burgeoning economies which are highly dependent on hydrocarbons to fuel their needs for economic growth. GCC nations are fully aware of the mounting consequences of increasing levels of CO2 on the environment, mainly attributed to soaring energy demand of domestic and industrial sector. Regional countries are undertaking concrete steps and measures to reduce their carbon footprint through the introduction of renewable energy and energy efficiency measures. Among other options, Carbon Capture and Storage, popularly known as CCS, can be an attractive proposition for GCC nations. What is CCS Carbon capture and storage (or carbon capture and sequestration) … Continue reading →
