Wayne Hicks at NREL describes research that’s created a virtual blockchain “prosumer” accounting system that replicates a live utility-scale grid. The goal of a real-world application is to allow countless individual households with their own electricity storage and generation to buy and sell power to each other; a truly revolutionary pathway. Clearly, it will require a system that securely accounts for vast amounts of transactions - a big enough … [Read more...]

Grid-scale Solar PV storage can use re-purposed old EV batteries
Once an EV battery has declined to 80% of its original capacity it is considered too weak for continued vehicle use. Recycling the battery – at that point - to make another one is expensive. MIT’s David Chandler describes how researchers there have run experiments and models to show that old EV batteries can instead be packed together and used as backup storage for grid-scale solar PV installations. It’s cheaper than building new Li-ion battery … [Read more...]
EU Recovery Package mustn’t sideline Green R&D
Today (Wednesday 27 May) the EC releases its COVID-19 Recovery package and Multiannual Financial Framework. The Green Deal and net-zero ambitions are expected to be a substantial part of it. Eleonora Moro and LĂ©a Pilsner at E3G draw attention to Research & Innovation (R&I, or R&D), often in danger of being seen as a luxury in times of crisis because the big wins are not immediate. Already, the EU could do much better. Looking at … [Read more...]
10,000 sq km of Solar in the Sahara could provide all the world’s energy needs
A little over 10 years ago David MacKay drew attention by saying “All the world’s power could be provided by a square 100km by 100km area in the Sahara.” Furthermore, MacKay’s calculation of the full potential of the region’s Concentrated Solar Power (CSP) totalled 25 times the TWh/year the world uses today. That was looking at the Middle East and North Africa’s (MENA) high solar irradiance, ample available land and the technologies of the day. … [Read more...]
Allam Cycle carbon capture gas plants: 11% more efficient, all CO2 captured
Globally, carbon capture is making precious little progress. Is the Allam Cycle natural gas power plant an important step forward? David Yellen at the Atlantic Council Global Energy Center explains that, according to its designers, its energy conversion efficiency is 59%, 11% more than a standard combined-cycle gas turbine plant that’s carbon capture-equipped. It also captures 100% of the CO2, 10% more than the standard. NET Power plans to bring … [Read more...]
A Just Transition can address systemic inequality, not just clean energy jobs
For some, the concept of a Just Transition means more than re-skilling former coal workers. It’s an opportunity to reduce systemic inequality in their society. Energy costs represent a high portion of the spending of the poor, so any major overhaul of the energy system, like the Transition, can have a direct and positive impact on them. Writing for the Regulatory Assistance Project (RAP), Alice Napoleon, Donna Brutkoski and Nancy Seidman describe … [Read more...]
Promises of future tech make hitting the 2°C target harder: a history
Writing for Carbon Brief, Duncan McLaren at Lancaster University runs through the history of climate negotiations to show that, over “five phases”, the continuous overhauling of models and target-setting have always resulted in promises to reverse emissions sometime in the future, a poor substitute for the real job of cutting emissions now. His main criticism is aimed at future carbon capture (CCS, BECCS) and net-zero-by-2050 policies: anything … [Read more...]
EU Recovery Package should earmark €90 billion public funding annually towards building renovation for EU-27, new analysis shows
BRUSSELS, Belgium, 20 May 2020 | BPIE – The Buildings Performance Institute Europe has published an analysis of the economic opportunity for Europe’s building sector, which could help mitigate economic damage of the COVID-19 pandemic. The findings show that the total amount of public funding required to trigger a significant scaling up of the renovation rate and depth would add up to €90 billion annually until 2050, with €76 billion annually … [Read more...]
Energy Post panel discussion – Cross-Border Capacity [VIDEO]
Whilst renewable generation continues to grow, cross-border capacity fails to keep up. On May 19, 2020, Energy Post hosted a unique panel qualified to discuss the issue and shed some light on how we got here and what the options might be going forward. The discussion was moderated by Erik Rakhou - alternate member of the ACER board of appeal and consultant at Baringa. Representing the European Commission was Florian Ermacora and for independent, … [Read more...]
Developing nations: Efficiency is cheaper than Coal in Indonesia
Developing economies face a particularly big challenge in reducing emissions. Their economies are growing rapidly, industrialising and urbanising. Their populations surely deserve the same rewards of wealth that the rich countries – the historical and per capita big emitters - have experienced. Can they get there without all the emissions? Indonesia believes so, committing itself to 29% unconditional emissions reductions by 2030. Virginie … [Read more...]
Wireless recharging of EVs as they drive?
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars. Stationary wireless EV charging has already been piloted and promoted by companies like Connected Kerb in the UK and car manufacturers. Experiments with the mobile version have also been conducted. Clearly, the less often an EV has to stop to recharge the better. But this has run into the problems of energy conversion … [Read more...]
Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power
The lockdown has unexpectedly allowed us to model certain aspects of the energy sector’s possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [Read more...]
Re-shaping the EU ETS as a safety net, not a driver
The EU ETS (Emissions Trading System) has struggled to cope with the current economic crisis which has caused a drop in the European carbon price, while the expected drastic drop in 2020 emissions will only add to the existing surplus of allowances. This highlights how necessary it is to reform the mechanism for managing this surplus or even to implement a carbon floor price, explain Charlotte Vailles at I4CE and Nicolas Berghmans at IDDRI. They … [Read more...]
Clean Energy threatened by lockdown of critical minerals supply
Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric transport and grid storage are now the largest consumers of lithium and cobalt. Examples of rising consumption abound for other … [Read more...]
Enefirst – Making Efficiency First operational: New project aims to support policy makers put the European guideline into practice in view of the EU Green Deal
The Enefirst consortium released its first publication, which defines the principle of Efficiency First (E1st) in a way to make it operational. The 2.5-year project, funded under the EU’s Horizon 2020 programme for Research and Innovation, seeks to provide decision makers in Europe with concrete policy recommendations based on quantitative analysis and best practice mapping. The publication represents the consortium’s first step towards meeting … [Read more...]
