Is bioenergy green? It depends, says Jessica Allen at the University of Newcastle. She lays out five key questions that should be asked about every bioenergy project. What is its source? Native forest residues, dedicated fast-growing biomass species, agricultural residues and “waste” biomass: all have pros and cons that must first be carefully measured. How many emissions are embodied in the collection and transport of the biomass to the plant? … [Read more...]
How can Biomass fulfil its potential in EU carbon markets?
In carbon markets such as the EU ETS participants must monitor and report their emissions and ultimately pay for them. Biomass occupies a unique place. It is well positioned to be a net-zero emissions energy source for hard-to-abate sectors. Coupled with effective on-site carbon capture technologies, it can be carbon negative. And there is a great diversity of project types involving forestry, biochar kilns, waste-to-energy, carbon capture and … [Read more...]
How much Carbon Capture will Germany need? Both nature-based and technological
Yet more studies have been published that show Germany needs carbon removal to meet its emissions targets. Simon Göss and Hendrik Schuldt at cr.hub add two, from the German Energy Agency and the Ariadne report (funded by the German Ministry of Education and Research), to those that already exist to shine more light on a carbon capture pathway. The main observation is that nature-based solutions (LULUCF: land use, land use change and forestry) … [Read more...]
10 Carbon Capture methods compared: costs, scalability, permanence, cleanness
We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
