The International Renewable Energy Agency’s (IRENA) latest report Renewable Power Generation Costs in 2018 details the global weighted-average levelised cost of electricity (LCOE) for all commercially available renewable technologies. It states that renewables are already the lowest-cost source of new power generation in many parts of the world today. By as soon as 2020, onshore wind and solar PV will join hydropower in consistently offering a … [Read more...]
Carbon Capture: Can CO2-EOR really provide carbon-negative oil?
Enhanced Oil Recovery (EOR) injects CO2 into oil reservoirs, increasing the pressure and forcing the oil out. 20% of global oil production uses EOR. But if that CO2 doesn’t stay underground it hasn’t been captured. If it was itself extracted from natural underground CO2, there is no benefit – or worse. Ideally, it should come from already captured CO2. But most oil wells are nowhere near a CCUS (carbon capture, usage and storage) facility: in the … [Read more...]
Interview bio-energy expert André Faaij: “So much nonsense has been told – high time for the real story”
“An enormous amount of nonsense” has been told about bio-energy, says André Faaij, scientific director of Energy Academy Europe and professor Energy Systems Analysis at the University of Groningen in the Netherlands. According to Faaij, it is high time for the real – scientifically validated – story. “The bio-based economy is indispensable for our climate policy and can mean huge progress for agriculture and nature in developing countries”. … [Read more...]
