From pulling carbon dioxide out of the air to turning water into fuel, innovators are developing new technologies and pairing existing ones to help slow global warming.
Achieving zero emissions in the energy sector by 2050 is technically and economically possible. Indonesia can modernise its economy through various green projects.
Ever watched a space shuttle launch? The fuel used to thrust these huge structures away from Earth’s gravitational pull is hydrogen. Hydrogen could also be used as a household energy source.
By embracing natural gas made from renewable sources, we can still use gas for heating, cooking and industry, while slashing greenhouse emissions and even keeping much of the same infrastructure.
Deriving fuel from trees costs more than wind and solar power and it emits more carbon than coal. There are many heated debates about this kind of energy, known as forest or woody biomass.
Natural gas is touted as a “bridging fuel” to displace coal while moving to a low-carbon economy. In New Zealand, this is shortsighted and could lead to stranded assets and hold back renewables.
The development of alternative airline fuels needs serious support from national governments if we are going to see greener skies overhead any time soon.
Rooftop solar power is exploding in the US but some scientists are pursuing a radically different route in renewable energy: storing solar energy as a liquid fuel.
Converting renewable energy into electricity is one thing; converting it into fuel is quite another. The vast majority of global energy demand is for fuel, and a renewable source could help us heat our…
