In the current policy environment many energy technologies can appear attractive with the right set of assumptions: discounted clean energy technologies (wind, solar and nuclear) where the discount rate is heavily influenced by risk (see graph) and, perhaps surprisingly, new load-following fossil fuel plants (especially natural gas) where continued wind/solar technology forcing actually provides substantial upside potential. CCS researcher Schalk … [Read more...]
Aligning the IEA Sustainable Development Scenario to Paris goals
As part of its World Energy Outlook 2018 report, on 13 November the International Energy Agency will publish its latest Sustainable Development Scenario that it claims shows governments and companies how to reach Paris’ climate change goals. To date, it’s fallen short – perhaps because it thinks the goals are too difficult to achieve, says Greg Muttitt of Oil Change International, which is calling on the agency to start showing how those goals … [Read more...]
Bioenergy carbon capture: Climate snake oil or 1.5C panacea?
Most models for meeting 1.5℃ or 2℃ climate change targets suggest we will be using bioenergy carbon capture and sequestration (BECCS) to mop up the world’s total annual CO2 emissions by around 2070 (for 2℃). This means moving from today’s three BECCS power plants to 16,000 by 2060. But, explains Paul Behrens of Leiden University, large-scale BECCS is a “monumentally tricky idea,” and, while aiming to fix climate disruption, it makes many things … [Read more...]
Why we can’t reverse climate change with negative emissions technologies
The United Nation’s panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5oC. But these techniques are largely unproven, and the technical, economic and environmental barriers of negative emissions technologies (NETs) are very real, states Howard J. Herzog, Senior Research Engineer at Massachusetts Institute of Technology and a leading expert in CO2 capture and storage. … [Read more...]
DNV GL’s Energy Transition Outlook shows massive shift of investment from oil and gas into power lines
The global energy transition will lead to a massive expansion of power lines at all voltage levels as well as a steep growth in the number of transformers and substations in the electricity system. This is one of the major new findings of the second edition of the Energy Transition Outlook, the annual flagship publication of global technical consultancy DNV GL. As a result, grid costs will triple, yet this cost explosion is offset by cost … [Read more...]
Decarbonising heavy industry can’t be done without large-scale CCS effort
The decarbonisation will require a profound transformation, writes David Hone, Chief Climate Change Advisor at Shell. Shell’s Sky climate scenario shows it can't be done without large-scale carbon capture and storage (CCS). A new initiative should boost progress on CCS. … [Read more...]
The plethora of better alternatives to wind and solar power and electric cars
Technology neutrality can activate more than ten times greater sustainable development potential than current technology-forcing policies, writes independent researcher Schalk Cloete. In the second part of a series which follows an article about the dangers of technology-forcing of wind and solar power and battery electric vehicles, Cloete reviews eight alternative sustainable development solutions that he believes have greater climate mitigation … [Read more...]
