Wind and solar power generation will continue to grow in the energy supply of the future, but its inherent variability (intermittency) requires appropriate energy systems for storing and using power. Storage of possibly temporary excess of power as methane from hydrogen gas and carbon dioxide is a promising option. With electrolysis hydrogen gas can be generated from (renewable) power. The combination of such hydrogen with carbon dioxide results in the energy carrier methane that can be handled well and may may serve as carbon feedstock of the future. Biogas from biomass delivers both methane and carbon dioxide. Anaerobic microorganisms can make additional methane from hydrogen and carbon dioxide in a biomethanation process that compares favourably with its chemical counterpart. Biomethanation for renewable power storage and use makes appropriate use of the existing infrastructure and knowledge base for natural gas. Addition of hydrogen to a dedicated biogas reactor after fermentation optimizes the biomethanation conditions and gives maximum flexibility. The low water solubility of hydrogen gas limits the methane production rate. The use of hollow fibers, nano-bubbles or better-tailored methane-forming microorganisms may overcome this bottleneck. Analyses of patent applications on biomethanation suggest a lot of freedom to operate. Assessment of biomethanation for economic feasibility and environmental value is extremely challenging and will require future data and experiences. Currently biomethanation is not yet economically feasible, but this may be different in the energy systems of the near future.
Power to methane provides a solution to a couple of two problems: unbalanced production and demand of wind plus solar power electricity and the low methane content of biogas by storing electricity via hydrogen into methane gas using carbon dioxide from biogas and methanogenic bacteria. The four-year project is performed by a consortium of three research institutes and five companies. In WP1 the-state-of- the-art of scientific knowledge on P2M technology is reviewed and evaluated.
PurposeThis study explores how and when intuitive forms of planning can be used in a family firm's succession process.Design/methodology/approachThe study uses an extended focus group meeting, consisting of individual, group and subgroup discussions with seven highly experienced external family business advisors in the Netherlands to gain a holistic understanding of the succession process and its underlying logic. The study also employs pre- and post-group questionnaires.FindingsThis study reveals that advisors perceive intuitive forms of planning as an integral part of the succession process, with the latter containing both intuitive and formal logic and activities. Both logics are used situationally and flexibly to deal with the uniqueness and unpredictability of the succession process and to build strong relations and manage relational dynamics in business families to address tasks, dilemmas and contingencies.Originality/valueThe succession process is an important part of business families' achievement of transgenerational intent. Creating commitment among potential successors begins when they are children, and understanding the role of the more intuitive forms of planning during the succession process will provide us with a more holistic perspective on its dynamics.
To reach the European Green Deal by 2050, the target for the road transport sector is set at 30% less CO2 emissions by 2030. Given the fact that heavy-duty commercial vehicles throughout Europe are driven nowadays almost exclusively on fossil fuels it is obvious that transition towards reduced emission targets needs to happen seamlessly by hybridization of the existing fleet, with a continuously increasing share of Zero Emission vehicle units. At present, trailing units such as semitrailers do not possess any form of powertrain, being a missed opportunity. By introduction of electrically driven axles into these units the fuel consumption as well as amount of emissions may be reduced substantially while part of the propulsion forces is being supplied on emission-free basis. Furthermore, the electrification of trailing units enables partial recuperation of kinetic energy while braking. Nevertheless, a number of challenges still exist preventing swift integration of these vehicles to daily operation. One of the dominating ones is the intelligent control of the e-axle so it delivers right amount of propulsion/braking power at the right time without receiving detailed information from the towing vehicle (such as e.g. driver control, engine speed, engine torque, or brake pressure, …etc.). This is required mainly to ensure interoperability of e-Trailers in the fleets, which is a must in the logistics nowadays. Therefore the main mission of CHANGE is to generate a chain of knowledge in developing and implementing data driven AI-based applications enabling SMEs of the Dutch trailer industry to contribute to seamless energetic transition towards zero emission road freight transport. In specific, CHANGE will employ e-Trailers (trailers with electrically driven axle(s) enabling energy recuperation) connected to conventional hauling units as well as trailers for high volume and extreme payload as focal platforms (demonstrators) for deployment of these applications.
MKB-bedrijven op het gebied van architectuur, gebiedsontwikkeling, ontwerp, digital design en technologie-ontwikkeling zien een nieuwe ‘markt’ ontstaan in de toenemende interesse voor de stedelijke commons. Dat zijn lokale gemeenschappen waarin mensen resources zoals energie, mobiliteit of woonruimte met elkaar delen en beheren, op een duurzame en pro-sociale manier. MKB-bedrijven zien kansen om in co-creatie met deze leefgemeenschappen nieuwe diensten en producten te ontwikkelen waarmee bewoners hun hulpbronnen gemeenschappelijk kunnen managen. MKB-bedrijven zien de ontwikkeling van stedelijke commons daarnaast als mogelijke oplossing voor urgente maatschappelijke vraagstukken en missies op het gebied van inclusieve woningbouw, duurzaamheid en de energietransitie. Voor het goed functioneren van de commons is een heldere articulatie en implementatie van hun onderliggende (maatschappelijke) waarden essentieel. Dit vraagt van MKB-bedrijven een zoektocht naar nieuwe manieren van gebieds- en technologie-ontwikkeling in samenwerking met bewoners. Een specifiek probleem daarbij betreft het vertalen van de commons-waarden naar een technologisch systeem dat het gezamenlijk beheer van hulpbronnen mogelijk maakt. Hiervoor wordt veel verwacht van digitale platformen en distributed ledgers technologies zoals de blockchain. Dit zijn databases die precies bijhouden wie wat bijdraagt en gebruikt. Ze koppelen zo’n boekhouding ook aan rechten, plichten en reputaties van de deelnemers. Bij de inrichting van zo’n systeem moeten ontwerpers steeds keuzes maken en rekening houden met spanningen tussen bijvoorbeeld privacy en transparantie, of individuele en collectieve belangen. In dit ontwerpproces stuiten MKBs op een kennishiaat. Hoe kunnen de onderliggende (maatschappelijke) waarden van commons-gemeenschappen 1) worden gearticuleerd en 2) vertaald naar een ontwerp voor de organisatie van een stedelijke commons met behulp van digitale platformen? Dit onderzoek verkent deze vragen in een fieldlab in Amersfoort, op twee ‘transfersites’ in Amsterdam en Birmingham, en met community of practice partners. Samen met hen worden een set design-principes en richtlijnen ontwikkeld voor het ontwerp van DLTs voor de stedelijke commons.
The transition to a circular, resource efficient construction sector is crucial to achieve climate neutrality in 2050. Construction stillaccounts for 50% of all extracted materials, is responsible for 3% of EU’s waste and for at least 12% of Green House Gas emissions.However, this transition is lagging, the impact of circular building materials is still limited.To accelerate the positive impact of circulair building materials Circular Trust Building has analyzed partners’ circular initiatives andidentified 4 related critical success factors for circularity, re-use of waste, and lower emissions:1. Level of integration2. Organized trust3. Shared learning4. Common goalsScaling these success factors requires new solutions, skills empowering stakeholders, and joint strategies and action plans. Circular TrustBuilding will do so using the innovative sociotechnical transition theory:1.Back casting: integrating stakeholders on common goals and analyzing together what’s needed, what’s available and who cancontribute what. The result is a joint strategy and xx regional action plans.2.Agile development of missing solutions such a Circular Building Trust Framework, Regional Circular Deals, connecting digitalplatforms matching supply and demand3.Increasing institutional capacity in (de-)construction, renovation, development and regulation: trained professionals move thetransition forward.Circular Trust Building will demonstrate these in xx pilots with local stakeholders. Each pilot will at least realize a 25% reduction of thematerial footprint of construction and renovation
