The decarbonisation of heavy industry is making little progress. There are two main reasons. Firstly, there are no easy technology wins. Efficiency and carbon capture have been the favoured options. But efficiency gains have their limits, and carbon capture is still proving very expensive. Secondly, governments don’t want their home industries to lose competitiveness incurring costs reducing emissions. Dolf Gielen and Paul Durrant at IRENA say a … [Read more...]
Optimising Cyanobacteria for carbon fixation and biofuels
The landscape can be changed for energy transition technologies by research breakthroughs, and that includes work on bacteria and proteins. The National Renewable Energy Laboratory (NREL) and its partners have been running experiments on cyanobacteria. These single-cell organisms, also using photosynthesis, fix carbon dioxide twice as efficiently as plants. They grow rapidly, doubling their numbers in three hours. The first step is to understand … [Read more...]
“Green” chemical plants that ramp up and down with wind, solar
One solution to variable renewables is to create customers that have no problem with ramping up and down production along with the power. In fact, when the wind and solar is producing too much power for the grid it can be bought very cheaply, making intermittent customers very happy. Jim Conca describes a new design for a Chlor-Alkali Chemical Plant that can “idle” without critical components of the plant degrading – the main reason for a plant … [Read more...]
New EU Industrial Strategy focuses on emissions, but is it enough?
This month the European Commission released its new EU Industrial Strategy to set the direction of travel for the EU economy in the context of the European Green Deal. Energy-intensive industries - like steel, cement, aluminium, paper and chemicals - account for roughly 17% of EU emissions and have struggled to reduce them in recent years. But Johanna Lehne at E3G doubts the strategy is enough to meet the ambition of becoming the first … [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...]
“Hard-to-abate” sectors need Hydrogen. But only 4% is “green”
40% of global greenhouse gas emissions come from “hard-to-abate” industry sectors like industrial processing and transport. Electrification won’t be enough. They also need hydrogen, argue Patrick Molloy and Leeann Baronett at Rocky Mountain Institute. Hydrogen production is already well established and growing. But it’s mainly for the chemical industry, which never meant it to be “green”: sure enough, only 4% of current hydrogen production is … [Read more...]
