Ethylene is a key component of the world’s vast appetite for plastics. But it’s normally made using fossils as a feedstock, and is energy-intensive to produce. So the chemicals industry has long sought a way to biologically manufacture ethylene. It would be a double-win for clean energy: it would capture CO2 and displace the fossil-based feedstocks. Connor O’Neil at NREL describes new research that makes ethylene in a “one-step” process fuelled … [Read more...]
Biofuels “light-to-power” slump: because photosynthesis is no match for Solar PV
The success of energy crops depends on many things. But the first link in the chain is a weak one: natural photosynthesis, the conversion of light into energy by plants. The problem is the efficiency of photosynthesis is no match for that of a modern solar PV cell. And while solar technology keeps improving, mother nature – not a signatory to the Paris Agreement – has no plans to do so. Any progress must come from biotechnology which is slow … [Read more...]
