Buildings represent one third of energy usage in the U.S., and that will be typical of similar economies around the world. The cost of re-fitting buildings to conserve energy is very high and can take decades. Specifically, 30% of the energy used to heat and cool buildings is down to the heat that either escapes or enters through windows. What if there was a way to control that heat flow without re-designing or replacing the windows? MIT’s Mary … [Read more...]
EV Charging Infrastructure: “hidden” soft costs are slowing take up
You don’t buy an EV if you’ve nowhere to charge it. So the take up of EVs depends on the availability – and therefore the costs - of charging infrastructure. Rocky Mountain Institute’s Chris Nelder describes the surprising conclusion of their recent report “Reducing EV Charging Infrastructure Costs”, that it’s the soft costs that are stubbornly refusing to go down in the U.S. That means things like permitting delays, complex utility … [Read more...]
The Six Energy Paradoxes that slow the sector’s progress
Gerard Reid at Alexa Capital takes a high level look at what he sees as six systemic problems faced throughout the energy sector. They can be found at every level, across all technologies and markets. He calls them the Six Energy Paradoxes. All of them are acting as a serious drag on progress, Transition or not. Take the Market Efficiency Paradox. Utilities should adjust their prices to meet changes in energy supply and demand. Higher supply or … [Read more...]
$7tn investor BlackRock announces Coal divestment, but not across all funds
BlackRock’s decision to divest from coal, as the world's largest asset manager with a long shareholder history of voting against climate action, sends a powerful signal. By mid-2020 BlackRock’s $1.8tn of actively managed funds will divest from any firm generating more than 25% of revenue from thermal coal. Further reviews of sectors heavily reliant on thermal coal will also take place. Tim Buckley, Tom Sanzillo and Melissa Brown at IEEFA welcome … [Read more...]
U.S. Presidential Election: for the first time, climate is a top priority
Another climate action “first” this year will be the 2020 U.S. Presidential election. Never before has climate change featured as a top priority for American politicians and voters, says Arnault Barichella writing for the IFRI Centre for Energy & Climate. It’s thanks to the growing evidence of human-caused global warming in collision with a current President who calls it all a hoax and has been rolling back the regulations of his predecessor. … [Read more...]
Lithium-Sulphur batteries: cheaper, greener, hold more energy
The rapid expansion of electric power across the world is putting a strain on battery production. The standard lithium-ion battery depends on minerals and metals in limited supply, so alternatives are needed urgently. Mahdokht Shaibani at Monash University describes the work of her team on developing lithium-sulphur batteries. There are many advantages, not least the abundance of sulphur, the 16th most common element on Earth. Added to that, … [Read more...]
EU pathway to 3m EV charge points by 2030
Right now the EU has around 185,000 public charge points, which is enough for today’s market (seven cars for each point). The current policy scenario targets 33m electric cars by 2030 (44m for climate neutrality). Transport & Environment’s Nico Muzi summarises their latest report that plots their ambitious pathway. It’s driven by the forceful idea of a European ‘right to plug’, and enabled by their new Public Charging Supply metric, using a … [Read more...]
Can emissions trading work without Article 6 of the Paris Agreement?
Article 6 of the Paris Agreement creates the framework for mechanisms that will allow nations and sub-national actors to trade emissions. Executed correctly, it must raise ambitions and reduce total emissions. It must also ensure there is transparent and accurate accounting for emissions, with no double-counting. It made little progress at December’s COP25. This was partly due to some countries “insisting on accounting loopholes”, writes Isabella … [Read more...]
Gas infrastructure leaks methane: fix it, or accelerate to clean energy
Natural gas, because it’s low-carbon, is being used as a bridge fuel away from the old fossil fuel world. But there are two main problems. The infrastructure leaks methane (the main component of the gas) which is 25 times more potent than CO2 over a 100-year period (and 86 times over a 20-year period!). And, crucially, nobody is properly measuring those leaks. That means policy makers are growing the gas mix without knowing by how much it’s … [Read more...]
Is Germany’s emissions drop thanks to the EU ETS, not Berlin?
The good news is that 2019 saw a big decrease in Germany’s emissions, meaning a 35% reduction since 1990. It was only 30.8% by 2018, so the acceleration was thanks to a sharp drop in coal use. But emissions rose in transport and buildings, making the 2020 target of 40% more daunting. Add to that the slump in wind installations (permit problems) and the planned nuclear exit by 2022 (will more fossil fuels be needed to fill that big gap?), … [Read more...]
CCUS, nuclear, industrial heat, hydrogen, smart grids: “large unit” innovation needs more support
How do we accelerate innovation across all technologies? Simon Bennett at the IEA breaks down the task into “small unit” and “large unit” challenges. The first is easier and moves faster. Thanks to their small size and unit cost, heat pumps, EVs and solar panels benefit from mass production, mass deployment (100,000 to 100m units/year globally) and large customer markets with fierce competition. They can also easily leverage other fast-evolving … [Read more...]
Nuclear in 2020: a global look ahead at policy, financing, politics, by country
Dan Yurman presents his worldwide review of nuclear’s prospects. 19 nations are covered. He explains while some countries are planning to scale down nuclear, like South Korea and France, some are increasing investment, like China. Others remain stuck over policy, pricing, financing and politics (e.g. Japan, the U.S.). Exporters of plants, led by Russia, are making moves – not always easily - in Eastern Europe and the Middle East. R&D … [Read more...]
High-efficiency “spacecraft” solar cells are coming down in price
Solar cells commonly used in spacecraft are highly efficient but too expensive to be used commercially down here on Earth. Two methods, HVPE (hydride vapour phase epitaxy) and the preferred MOVPE (metalorganic chemical vapour phase epitaxy), have been used to make these super-cells, reaching efficiencies of 29.1%. The National Renewable Energy Laboratory (NREL) says its scientists have discovered a method, D-HVPE, that should achieve those … [Read more...]
Don’t wait for international agreements. Sector-wide action can accelerate the Transition
December’s COP25 in Madrid showed how difficult it is proving to get agreement between nations on how to ramp up the deep decarbonisation the world needs. David Victor at the University of California, San Diego, writing for Rocky Mountain Institute, accepts that international consensus is never going to be easy. Instead, he recommends that individual sectors take control of their destiny. His co-authored report “Accelerating The Low Carbon … [Read more...]
