A Qatar Airways flight from London to Qatar has become the first passenger plane to be powered by cleaner-burning natural gas that was converted to kerosene.
“Today’s flight opens the door to an alternative to oil-based aviation fuel,” said Malcom Brinded, international executive director of Royal Dutch Shell, which is partnering with Qatar Petroleum to produce so-called gas-to-liquid (GTL) kerosene from Qatar’s abundant natural gas reserves.
Biofuels – made from algae and non-food plants – are emerging as a potentially viable alternative to conventional jet fuels. Although big challenges remain, the reductions in greenhouse gas emissions could be major.
Earlier this year, a Continental jet accelerated down the runway at George Bush Intercontinental Airport in Houston. Nothing out of the ordinary for Capt. Rich Jankowski, who countless times in his 38-year career had eased such two-engine Boeing 737-800s into the sky. Except on this experimental flight, one of the engines Jankowski relied on was burning fuel derived from microscopic algae to push the 45-ton aircraft into the air and keep it aloft — a first in aviation history.
Africa is the most under-supplied region of the world for electricity, and access to it is very different throughout the continent. While industry receives plenty of cheap power, 80% of the population lives off the power grid. As in other parts of the world, African economies utterly depend on electricity, “but levels of inequality are particularly pronounced here due to the inherent unevenness of ‘electric capitalism’ on the continent,” writes David A. McDonald in his recent book Electric Capitalism: Recolonising Africa on the Power Grid.
The international community is trying to improve the quality of life in Africa, and different sources of energy are being developed and installed. “Initial delivery of electric service to rural Africa is far from a ‘one size fits all’ technical solution, especially given the seasonal diversity of energy needs, as well as the availability and quality of candidate renewable energy resources”, argues S.R. Connors in an article titled “Providing Electricity Services to Rural Africa.
