Schalk Cloete summarises his co-authored study that explains how to make hydrogen at unbeatably low prices from coal/biomass co-gasification. Though the âblueâ hydrogen process creates CO2, the self-contained plant using a membrane-assisted water-gas shift (MAWGS) reactor means 100% is captured easily. Better still, the use of biomass means the plant achieves negative emissions. The overall efficiency of the process is a very impressive 69%. The … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
Buildings: France and Flanders lead on decarbonising new builds
Buildings are responsible for 36% of total EU carbon emissions. So, since the start of 2021 European legislation requires all new buildings to be ânearly zero energyâ. The frontrunners are France and Flanders in Belgium, according to a new report from the Buildings Performance Institute Europe (BPIE), writes Clare Taylor. Both jurisdictions have plans for phasing out fossil fuels in new buildings within five years. Taylor explains how Flanders … [Read more...]
What is making Denmark a decarbonisation success? Policy, society, geography
Denmark is proving itself to be a decarbonisation leader, happy to turn its back on its history of oil and gas production and heavy reliance on coal. Its ambitious goal of cutting GHG emissions by 70% by 2030 makes it a global policy frontrunner, second only to Finland which aims to be climate neutral by 2035. Thibault Menu references his report for IFRI that asks what makes Denmark special. It has a long tradition of  providing stability and … [Read more...]
EU Recovery funds: where is the support for District Heating?
District Heating is an efficient way to heat homes, particularly in a country like Latvia where 58% of its primary energy consumption is used for heating. But SelÄ«na VancÄne at Riga City Council is very concerned that the draft EU Recovery plans do not include any support under the climate goals for district heating projects. Perhaps itâs because of a blind spot: most of Europe is prioritising individual heating units powered by electricity. … [Read more...]
Swedenâs new âprosumersâ: electricity generation at the city, village and residential level
54% of Swedenâs power already comes from renewables â the target is 100% by 2040 - and more and more is being generated locally on a small distributed scale, says Harry Kretchmer writing for the World Economic Forum. âDistrict Heatingâ plants are today using excess heat to warm over 75% of Swedish homes. Residential generation is happening too, creating âprosumersâ who both produce and consume. In Ludivika, 1970s flats have been retrofitted with … [Read more...]
Waste Heat Recovery can help replace Polandâs District Heating coal
Three quarters of all district heating in Poland comes from burning coal. So the country is looking for ways to reduce this. Itâs why subsidies are provided for combined heat and power (CHP) plants that burn either coal, gas or biomass, which all have lower emissions. But a report by IEEFA authored by Gerard Wynn, Arjun Flora and Paolo Coghe says that waste heat recovery (WHR) â currently unsubsidised â is both emissions free and can be … [Read more...]
No Energiewende without WĂ€rmewende: 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...]
