The residential sector presents one of the most pressing decarbonisation challenges, especially within historically gas-dependent nations such as the UK. Compounding this challenge, issues of social acceptance have slowed efforts to advance the residential decarbonisation agenda in the UK context. To date, existing technologies such as heat pumps and smart meters, as well as emerging technologies
Hybrid energy systems have become a promising strategy for enhancing power utilization efficiency while preserving ecology. Previous research has predominantly focused on developing models with fixed ecological constraints. However, the fixed ecological constraints overlook dynamic ecological uncertainty and its interaction with operation decisions. This study proposes adaptive operating rules for
Colloidal halide perovskite nanocrystals are promising candidates for next-generation optoelectronics because of their facile synthesis and their outstanding and size-tunable properties. However, these materials suffer fromrapid degradation, similarly to their bulk perovskite counterparts. Here, we survey the most recent strategies to boost perovskite nanocrystals stability, with a special focus o
In this paper, balancing electricity production using renewable energy such as wind power, PV cells, hydropower, and CHP (combined heat and power) with biomass is carried out in relation to electricity consumption in primarily one major region in Sweden, SE-3, which contains 75% of the country’s population. The time perspective is hours and days. Statistics with respect to power production and con
District heating and cooling systems offer a cost-effective and secure supply of heating and cooling to connected buildings. They are widely recognised as a key solution to decarbonise the building sector due to their high potential of integrating renewable energy sources. The systems traditionally involved generating heating and cooling centrally with distribution through separate pipes before de
This study applies the technological innovation system framework to the case of the fuel cell sector in Taiwan. Many Asian latecomers, such as Taiwan, tend to adopt a top-down approach to emphasize the importance of environmental issues but the result is limited. We aim to take Taiwan’s fuel cell innovation system as an example to explore why Taiwan has formulated a technological innovation system
When trying to integrate more fossil-free heat sources such as renewable energy and heatrecycled from other processes into the current district heating systems, problems occur due tothe high temperature levels in the systems. There are many reasons to why the temperaturelevels are high, but one frequently occurring issue is that the return temperatures of thecustomer in
Softwood is of interest as a renewable carbon source for production of lactic acid. Softwood hydrolysate contains a high content of mannose. Lactic acid production from mannose by two modified strains, L-lactic acid producing Pediococcus acidilactici TY112 and D-lactic acid producing ZP26, was investigated in the current work. The two strains efficiently converted mannose to L- and D-lactate isome
Transitioning into a sustainable energy system is becoming ever more pressing as the reality of an anthropogenic ecological crisis becomes difficult to ignore. Due to the complexity of the matter, proposed solutions often address the symptoms of the current socioeconomic configuration rather than its core. To conceptualise possible future energy systems, this Perspective focuses on the disconn
Enabling vehicles to draw energy from an electric road system (ERS) significantly reduces the need for battery capacity on board the vehicle. It is not necessary, nor realistic, to cover every meter of every stretch of road with ERS. The question then arises how and where the ERS sections should be placed. One way of doing it is to place equally long sections of ERS with a certain separating dista
Anion exchange membrane water electrolysis (AEMWE) is a potentially low-cost and sustainable technology for hydrogen production that combines the advantages of proton exchange membrane water electrolysis and traditional alkaline water electrolysis systems. Despite considerable research efforts in recent years, the medium-term (100 h) stability of AemionTM membranes needs further investigation. Thi
Stiff, elastic, viscous shear thinning aqueous gels are formed upon dispersion of low weight percent concentrations of cationically modified cellulose nanofibrils (CCNF) in water. CCNF hydrogels produced from cellulose modified with glycidyltrimethylammonium chloride, with degree of substitution (DS) in the range 10.6(3)-23.0(9)%, were characterised using NMR spectroscopy, rheology and small angle
Drag torque in a disc brake is the residual torque when the brake is not activated. This torque can adversely influence the total energy consumption, life of the brake components, and level of airborne wear particles from vehicles. Drag torque is of special interest for long haul trucking since it could have an effect of the total energy consumption. Drag torque performance of a disc brake is usua
Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently attached to the enzyme, some GHs are able to catalyse synthesis reactions called transglycosylation. In transglycosylation reactions a hydroxyl-co
Neuromorphic computing has seen great interest as leaps in artificial intelligence (AI) applications have exposed limitations due to heavy memory access, with the von Neumann computing architecture. The parallel in-memory computing provided by neuromorphic computing has the potential to significantly improve latency and power consumption. Key to analog neuromorphic computing hardware are memristor
Theories of energy justice are standardly used to evaluate decision-making and policy-design related to energy infrastructure. All too rarely attention is paid to the need for a method of justifying principles of justice as well as justice-based judgments that are appealed to in this context. This article responds to this need by offering an engaged ethics approach to normative justification usefu
Popular Abstract in Swedish Europaparlamentet vill minska primärenergianvändningen samt minska beroendet av energiimport till unionen (EU Direktiv 2012/27/EU). Ett hjälpmedel för att uppnå detta mål kan vara användandet av individuell mätning och debitering (IMD) av värme och varmvatten i flerbostadshus. IMD innebär att boende i flerbostadshus endast ska betala för deras egen konsumtion, vilket skIndividual metering and charging (IMC) means that tenants in multi-apartment buildings should pay only for their own energy consumption, which gives an economic incentive for energy-conscious behaviour. In April, 2014, Swedish legislation about energy metering in buildings (SFS 2014:267) was passed by the Swedish Parliament as an implementation of the EU Energy Efficiency Directive 2012/27/EU. The
The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. Attention has also been devoted to the quest for sustainability within the field of chemistry. The concept of “green chemistry” is being intro
District heating is one of the technologies that can contribute to the decarbonisation of the European heat sector. Nonetheless, these infrastructures only deliver about a tenth of the heat demands in the continent. Therefore, it is essential to assess the expansion potential of these systems and to identify which areas should be target for further investigations, which calls for easy-to-use and s
