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...]
Can Teresa Ribera transform Spain into a green champion?
In a draft bill released on 13 November, the Spanish government is proposing to ban fossil fuel subsidies and fracking, reduce greenhouse gas emissions by 20% by 2030 (37% compared to current levels) and 90% by 2050, boost the share of renewables to 35% (70% of power generation) in 2030 and discourage diesel and petrol cars. Natalie Sauer of Climate Home News portrays the woman behind the plan, ecological transition minister Teresa Ribera, and … [Read more...]
Study says no way to decarbonise the gas sector by 2050
Gas industry advocates argue that expansion of gas infrastructure is justified because it will be possible to switch to low-carbon gases such as hydrogen and biomethane in future. But research by the International Council on Clean Transportation (ICCT) predicts that biomethane production will remain modest, even with massive subsidies. … [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...]
Are solar microgrids the future in the developing world?
Setting out to evaluate the real-world performance of solar microgrids in developing countries, a team from the Energy Institute at Haas partnered with startup Gram Power to provide small smart grid systems to unelectrified rural communities in India. While many industry experts see microgrids as important for future electrification, what the team found was that few communities wanted them, and they were difficult to implement and operate. … [Read more...]
Energy transition: The greatest switch capital markets have ever seen
Even the most engaged energy pundits tend to gloss over what may be one of the biggest changes of all in a clean energy transition: how we pay for and finance the energy we use, and what that may mean for the investors, industries and companies that provide that energy. David Nelson of Climate Policy Initiative explains why investment strategies, financial markets and business models also need to transform. … [Read more...]
Tesla big battery defies sceptics, sends industry bananas over performance
It’s less than a year since the Tesla big battery was installed at Hornsdale in Australia and the world’s largest lithium-ion battery has exceeded all expectations, says Giles Parkinson of Reneweconomy.com. Quicker, cheaper and with greater reliability, versatility, accuracy and efficiency than predicted, the storage system also looks set to provide a fast return on investment – results that have led to a rash of new battery projects in the … [Read more...]
