A growing number of countries are announcing increasingly ambitious renewable energy targets. But how do you deliver the results? IRENAâs Elena Ocenic explains that they have developed a toolset for countries to plot their unique pathway to success. Those tools range widely across technology, market design and regulation, system operation practices, and business models. The article lists the tools, and runs through some notable successes. Ocenic … [Read more...]
Gas Switching Reforming: making Hydrogen to balance variable Wind, Solar
What is the best technology to balance the variable output of wind and solar? When there is little wind and sun the plant must produce power to compensate. When thereâs too much wind and sun it must utilise that excess power. In other words, given the high capital cost of the new balancing technology it must do both profitably enough to cover the time sitting idle. A paper co-authored by Schalk Cloete looks at Gas Switching Reforming (GSR). The … [Read more...]
The cost of climate inaction: putting a $ price on 4.5°C warming
Oriana Tannenbaum and Rushad Nanavatty at Rocky Mountain Institute (RMI) have gathered data that puts a price on not making the necessary investments in tackling climate change. For the U.S., a 4.5°C warming scenario (by 2050) will cost $5.2tn. At a more drastic 6°C the cost is $17tn. These projections are hard to do when treating the climate as an âinfrastructure assetâ, though proven methodologies do exist for tradition assets, and the authors … [Read more...]
The EU can support Central and East Europeâs transition
Six Central and East European nations, heavily dependent on coal, have been very cautious about the pace of the EUâs transition. For them - Bulgaria, Czechia, Hungary, Poland, Romania and Slovakia - the political and economic disruption looks far harder to bear. E3G has just released a report that suggests this picture can change. The reportâs authors â Felix Heilmann, Rebekka Popp and Ada Ămon â explain that coal is becoming less profitable, … [Read more...]
Biofuels âlight-to-powerâ slump: because photosynthesis is no match for Solar PV
The success of energy crops depends on many things. But the first link in the chain is a weak one: natural photosynthesis, the conversion of light into energy by plants. The problem is the efficiency of photosynthesis is no match for that of a modern solar PV cell. And while solar technology keeps improving, mother nature â not a signatory to the Paris Agreement â has no plans to do so. Any progress must come from biotechnology which is slow … [Read more...]
No Energiewende without Wärmewende: making Germanyâs Heating emissions climate neutral (…nearly)
In Germany, space and water heating in buildings accounts for almost a third of total final energy consumption. Because over 90% of its 22m buildings are fuelled by oil and gas, that makes the sector emissions very intensive. The governmentâs ambition is to have a "nearly climate neutral building stock" by 2050. But although those emissions have fallen by 44% since 1990, progress has largely stagnated since 2011. Freja Eriksen at Clean Energy … [Read more...]
Carbon Tax: âlaboratoryâ Europe shows U.S. it has no effect on aggregate jobs, growth
The issue of carbon taxes is under debate in the U.S. Congress. The fear is a new tax will destroy jobs and hinder growth. Will it? Meredith Fowlie at the Energy Institute at Haas says the U.S. should see Europe as a very useful carbon tax laboratory experiment: half the countries have some sort of tax, the other half donât. Sheâs pulled together evidence to answer the simple question: does a carbon tax affect aggregate employment and growth. Her … [Read more...]
U.S. EIA predicts Renewables will surpass Coal by 2021
Renewable electricity generation in the U.S. has risen so fast in the last 10 years that itâs expected to surpass coal by 2021, according to the latest report from the nationâs Energy Information Administration (EIA). This would have been âunthinkableâ in 2010, says Dennis Wamsted at IEEFA. Back then, nationwide, utility-scale solar generated 1.29bn kWh and wind 94.6bn kWh. By 2021 solar will have risen almost a hundredfold to 122bn kWh and wind … [Read more...]
Modelling total costs for Onshore Wind power plants: from site prep to grid connection
The costs of wind turbines is dropping. But that means all the other capital costs - site preparation, foundations, infrastructure, tower construction â will become a bigger part of the total. In the U.S. they currently account for around 30% of the capital expenditures needed to install a land-based wind plant. To keep those costs under control the National Renewable Energy Laboratory (NREL) has created a comprehensive open-source modelling … [Read more...]
Oil & Gasâs future: diversify into clean electricity, new fuels, says IEA
The oil and gas industry is not doing nearly enough to meet Transition targets, says the IEA. Only 1% is invested in non-core activities. That needs to rise to 15% within 10 years. The IEAâs article summarises their comprehensive report âThe Oil and Gas Industry in Energy Transitionsâ, released this month. It explains how the industryâs existing skills and âdeep pocketsâ make them ideally placed to invest in low-carbon fuels (Hydrogen, … [Read more...]
âClimate leaderâ UK: why did low-carbon electricity generation stall in 2019?
In 2019, just 1TWh of low-carbon electricity (wind, solar, nuclear, hydro, biomass) was added in the UK. Thatâs after a decade of adding an average of 9TWh/year. Why? The UK needs to know, given an extra 15TWh/year is required until 2030 to meet emissions goals on top of the planned electrification of transport and heating. Carbon Briefâs Simon Evans runs through their thorough analysis. Wind power alone rose by 8TWh in 2019, but was offset by … [Read more...]
Electric utilities: pathway to a costs and pricing revolution
The 20th century method of setting electric utility rates are being made redundant by the new technologies of the modern age. Itâs currently a three-step process - determining the revenue requirement, deciding how to divide costs among ratepayers, then designing the rates themselves. It uses traditional categories: generation, transmission and distribution; cost classifications (energy-related, demand-related, customer-related); customer/rate … [Read more...]
HVAC: New window âfilmâ cuts cooling load by 30%. No need for re-fits
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? MITâs Mary … [Read more...]
EV Charging Infrastructure: âhiddenâ soft costs are slowing take up
You donât buy an EV if youâve nowhere to charge it. So the take up of EVs depends on the availability â and therefore the costs - of charging infrastructure. Rocky Mountain Instituteâs Chris Nelder describes the surprising conclusion of their recent report âReducing EV Charging Infrastructure Costsâ, that itâs 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 sectorâs 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...]
