Verzijlbergh, R.A. (author), De Vries, Laurens (author), Dijkema, G.P.J. (author), Herder, P.M. (author)The integration of large amounts of variable renewable energy poses fundamental challenges to the operation and governance of the energy system. In this article we address the main institutional challenges that are caused by the integration of variable renewable energy sources like solar and wind energy in the European power system. We first...journal article 2017

Bollinger, L.A. (author), Dijkema, G.P.J. (author)This paper reports the development and results of a model exploring the resilience of the Dutch electricity transmission infrastructure to extreme weather events. Climate change is anticipated to result in an increase in the frequency and severity of extreme weather events over the coming decades. Situated in a low-lying coastal delta, the...journal article 2016

Chappin, E.J.L. (author), Dijkema, G.P.J. (author)A framework for the modeling and simulation of transitions is presented. A transition, “substantial change in the state of a socio-technical system”, typically unfolds over a long timespan. We therefore suggest to use simulation to inform transition managers on the effect of their decisions. Transition models preferably meet five functional...journal article 2015

Chmieliauskas, A. (author), Chappin, E.J.L. (author), Dijkema, G.P.J. (author)AgentSpring is a new agent-based modeling framework especially suited to model and simulate complex socio-technical systems, such as energy markets or transport infrastructures. Common problems encountered when modeling and analyzing such systems are how to represent the variety of facts that describe the system and how to allow agents to make...conference paper 2012

Kasmire, J. (author), Dijkema, G.P.J. (author), Nikolic, I. (author)Horticulture, a pillar of the Dutch economy, has already achieved remarkable productivity increases through the use of natural gas for heating, lighting and CO2. Further innovative technologies that could aid the transition toward sustainable energy use, including heat/cold storage and deepgeothermal heat sources, are currently in development...conference paper 2012

Bollinger, L.A. (author), Dijkema, G.P.J. (author)While we rely on the continuous functioning of infrastructures such as water, electricity and Internet, 100% uptime is not possible. Infrastructure systems must therefore be resilient – they must be capable of flexing in response to disruptions and recovering quickly. In this paper we explore options for supporting infrastructure resilience from...conference paper 2012

Haruyama, S. (author), Kim, S.K. (author), Beiter, K.A. (author), Dijkema, G.P.J. (author), De Weck, O.L. (author)We developed a new education curriculum called "ALPS" (Active Learning Project Sequence) at Keio University that emphasizes team project-based learning and design thinking with systems engineering techniques. ALPS is a 6 month course, in which students work as a team and design and propose innovative systems. Students identify requirements,...conference paper 2012

Chmieliauskas, A. (author), Chappin, E.J.L. (author), Davis, C.B. (author), Nikolic, I. (author), Dijkema, G.P.J. (author)Our world is a complex socio-technical system-of-systems (Chappin & Dijkema, 2007; Nikolic, 2009). Embedded within the geological, chemical and biological planetary context, the physical infrastructures, such as power grids or transport networks span the globe with energy and material flows. Social networks in the form of global commerce and the...book chapter 2012

Nikolic, I. (author), Dijkema, G.P.J. (author)Infrastructure systems for energy, water, transport, information etc. are large scale socio-technical systems that are critical for achieving a sustainable world. They were not created at the current global scale at once, but have slowly evolved from simple local systems, through many social and technical decisions. If we are to understand them...journal article 2010

Chappin, E.J.L. (author), Dijkema, G.P.J. (author), De Vries, L.J. (author)Carbon taxation and emission trading are policy instruments for achieving significant CO2 emission reduction by inducing a shift in technology and fuel choice. Simulations with a quantitative agent-based model of a competitive electricity generation sector show that under both policies CO2 emissions increase for 10-15 years due to the long life...book chapter 2010

Chappin, E.J.L. (author), Dijkema, G.P.J. (author)Under the Kyoto Protocol, governments agreed on and accepted CO2 reduction targets in order to counter climate change. In Europe one of the main policy instruments to meet the agreed reduction targets is CO2 emission-trading (CET), which was implemented as of January 2005. In this system, companies active in specific sectors must be in the...journal article 2009

Dijkema, G.P.J. (author)Hydrocarbon and water are supplied to the anode (2) in a solid fuel cell (1), whilst oxygen is supplied to the cathode (3) to form synthesis gas. Carbon monoxide is converted into carbon dioxide, leaving a hydrogen-rich flow of gas with a low water vapor content. A method for preparing a hydrogen-rich gas stream (B) comprises the conversion of a...patent 1999

Dijkema, G.P.J. (author)Abstract of WO 9733828 (A1) The invention relates to a method for the production of ammonia, wherein a hydrogen-comprising discharge flow is utilized for the depletion of oxygen in air. Subsequently the oxygen-depleted air is - as nitrogen-comprising flow - brought into contact with water gas, which is the hydrogen - comprising flow. Oxygen...patent 1997
