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 Parisâ climate change goals. To date, itâs fallen short â 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 1.5â or 2â climate change targets suggest we will be using bioenergy carbon capture and sequestration (BECCS) to mop up the worldâs total annual CO2 emissions by around 2070 (for 2â). This means moving from todayâs three BECCS power plants to 16,000 by 2060. But, explains Paul Behrens of Leiden University, large-scale BECCS is a âmonumentally tricky idea,â and, while aiming to fix climate disruption, it makes many things … [Read more...]
Why we canât reverse climate change with negative emissions technologies
The United Nationâs 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 GLâs 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. Shellâs 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...]
EU policy must wake up to carbon dioxide removal
Most scenarios to meet the Paris Agreementâs targets require negative emissions technologies. However, carbon dioxide removal is not part of the EUâs climate policy yet. Its integration presents a serious challenge to the EUâs low-carbon policy paradigm and experience, write Oliver Geden of the German Institute for International and Security Affairs, Vivian Scott of the University of Edinburgh and James Palmer of the University of Bristol. … [Read more...]
The dangers of green technology-forcing
Current technology-forcing policies imply that wind and solar power, combined with battery electric vehicles, represent our only viable energy future, observes independent researcher Schalk Cloete. Given the fundamental limitations of these technologies, this is a very dangerous notion, he argues. A shift to technology-neutral policies is needed, especially in developing nations. … [Read more...]
How Shellâs new Sky scenario achieves net zero emissions
In Shell's recently published Sky climate scenario, the energy system reaches net zero emissions by 2070 using several technologies that are at an early stage. David Hone, Chief Climate Change Advisor at Shell, explains how this would work and why Shell regards this scenario as plausible. Courtesy David Honeâs Shell Climate Change blog … [Read more...]
Poland’s love affair with coal: can the EU do anything about it?
The Polish governmentâs strong commitment to coal goes against EU policy direction and against market conditions, write Anna Mikulska of the Baker Instituteâs Center for Energy Studies and Eryk Kosinski of Adam Mickiewicz University. But coal has a special place in the nationâs collective heart. To wean Poland off coal will require EU support to coal-dependent regions and for alternative energy sources, the authors argue. … [Read more...]
Shellâs new SKY scenario shows how to meet the goals of the Paris agreement
Shell has launched a new scenario that illustrates a "technically possible but challenging pathway" for society to meet the goals of the Paris Agreement on climate change. The Sky outlook sees a rapid energy transition taking place over 50 years reaching net-zero emissions in the energy system by 2070. Courtesy David Honeâs Shell Climate Change blog. … [Read more...]
Shell executive describes inevitable transition to carbon-free energy
"Shell wants to be a voice and a leader in the energy transition", said Harry Brekelmans, the projects and technology director for Royal Dutch Shell, a founding member of the MIT Energy Initiative (MITEI). But the company must "not abandon the process that made us a leader", namely production and distribution of oil and gas. Brekelmans met with groups of MIT students and faculty members for a public discussion about energy issues with MITEI … [Read more...]
100% renewable energy for 139 nations detailed in Stanford report
Mark Z. Jacobson, the famed professor at the Stanford School of Earth, Energy, and Environmental Sciences, and 26 of his colleagues have compiled a report that shows exactly how 139 nations could transition to 100% renewable energy by 2050 without throwing millions of people out of work. In fact, they contend that the changeover would actually spur job growth while dramatically reducing carbon emissions, writes Steve Hanley. Article courtesy of … [Read more...]
Carbon capture and storage: too expensive for reducing power sector emissions
The hope that carbon capture and storage (CCS) can ever play a significant role in the reduction of power sector emissions is misplaced, write Jeffrey Rissman and Robbie Orvis of Energy Innovation, a San Francisco-based energy and environmental policy think tank. Coal-fired power is already more expensive than unsubsidized onshore wind and solar PV. Adding CCS will only increase this gap. The subsidies required to bring CCS costs in line with … [Read more...]
