Biomass-to-Energy in Taiwan
In order to reduce the emissions of carbon dioxide (CO2) from existing fossil fuel plants, biomass or lignocellulose-based waste was used directly as a solid fuel or as a supplement to fossil fuels. Although the traditional combustion of solid-type biomass in open fires or cook stoves could have an impact on human health and the environment, bioenergy for power generation (or electricity) and transport fuels (i.e., bioethanol and biodiesel) has been growing quickly, mainly because of the policy support and regulatory compliance. In order to reduce the dependence on imported energy supply as well as to mitigate greenhouse gas (GHG) emissions, the Taiwanese government has been actively promoting renewable energy development to increase the indigenous energy supply for electricity and heat generation in the energy and industrial sectors.

Substance Release from Polyelectrolyte Microcapsules
Controlled release of substance from polyelectrolyte microcapsules is a triggered degradation of the microcapsule membrane that is extensive enough to release the contained substances out into the environment. Membrane degradation can be a result of enzymatic digestion, ultrasound or light exposure, heating, application of a magnetic field, pH or ionic strength changes in the solution or bacteria-mediated processes. This technology can be used for the targeted release of drugs, and for the development of self-healing materials and new generation pesticides.

Aerobic Granular Sludge–Membrane BioReactor (AGS–MBR)
Membrane-fouling represents a major drawback hampering the wider application of membrane bioreactor (MBR) technology. Fouling can be mitigated by applying aerobic granular sludge technology, a novel kind of biofilm technology characterized by high settleability, strong microbial structure, high resilience to toxic/recalcitrant compounds of industrial wastewater, and the possibility to simultaneously remove organic matter and nutrients. Different schemes can be foreseen for the AGS–MBR process. However, an updated literature review reveals that in the AGS–MBR process, granule breakage represents a critical problem in all configurations, which often causes an increase of pore-blocking.

Natural Coagulants for Pharmaceutical Removal from Wastewater
Pharmaceutical contamination threatens both humans and the environment, and several technologies have been adapted for the removal of pharmaceuticals. The coagulation-flocculation process demonstrates a feasible solution for pharmaceutical removal. However, the chemical coagulation process has its drawbacks, such as excessive and toxic sludge production and high production cost. To overcome these shortcomings, the feasibility of natural-based coagulants, due to their biodegradability, safety, and availability, has been investigated by several researchers.

Scour Protections Design Optimization
The offshore wind is the sector of marine renewable energy with the highest commercial development at present. The margin to optimise offshore wind foundations is considerable, thus attracting both the scientific and the industrial community. Due to the complexity of the marine environment, the foundation of an offshore wind turbine represents a considerable portion of the overall investment. An important part of the foundation’s costs relates to the scour protections, which prevent scour effects that can lead the structure to reach the ultimate and service limit states. Presently, the advances in scour protections design and its optimisation for marine envi-ronments face many challenges, and the latest findings are often bounded by stakeholder’s strict confidential policies.

Plug-In Electric Vehicles in the Netherlands
The adoption of plug-in electric vehicles in the Netherlands is actively supported by the Dutch government through the exemption of the registration fee and road taxes. These purchase incentives have been adjusted over time. Considering the potential of plug-in electric vehicles in the country due to its relative small size and geography, the Dutch government set a target of 15,000 to 20,000 electric vehicles with three or more wheels on the roads in 2015; 200,000 vehicles in 2020; and 1 million vehicles in 2025. The first two targets were achieved two years earlier than planned. The Dutch plug-in market was dominated by plug-in hybrids until 2016, when the tax rules changed after it became apparent many users rarely used the electric motors and only bought the cars for their tax advantage. In 2019, plug-in electric passenger cars had a market share of 14.9%, and rose to 24.6% in 2020, with battery electric vehicles dominating sales in both years. (As of December 2020), there were 297,380 highway-legal light-duty plug-in electric vehicles on the road in the Netherlands, consisting of 182,481 fully electric cars, 108,652 plug-in hybrids, and 6,247 all-electric light utility vans. (As of December 2012), the Netherlands was the country with the highest ratio of slow charging points to electric vehicles (EVSE/EV), with a ratio of more than 0.50, while the U.S had a slow EVSE/EV ratio of 0.20. The Netherlands' mix of slow and fast chargers has allowed it to become the country with the highest number of charging point per capita in the world. (As of December 2016), there were 11,768 public slow charging points available 24/7, 14,320 slow charging point with limited public access, 612 public and semi-public fast charging points, and over 72,000 private charging points.

Prospects of Using Hydrogen–Methane Blends
The use of methane–hydrogen mixtures in internal combustion engines improves their performance and emission characteristics. The most important aspect is the concentration of hydrogen in the fuel mixture, which affects the combustion process of the fuel and determines the optimal operating conditions of the engine. When using methane–hydrogen mixtures with low hydrogen content, the safety measures and risks are similar to those that exist when working with natural gas. Serious logistical problems are associated with the difficulties of using the existing gas distribution infrastructure for transporting methane–hydrogen mixtures.

Power systems stability with IBGs
Electrical power system stability is of upmost importance for a secure and reliable supply of electrical energy to residential, commercial and industrial premises. Voltage stability of microgrids, as new components of a power system, is an emerging research area within the concept of power system stability. The main purpose of developing microgrids is to facilitate the integration of renewable energy sources into the power grid. Renewable energy sources are normally connected to the grid via power electronic inverters. As various types of renewable energy sources are increasingly connected to the electrical power grid, power systems of the near future will have more inverter-based generators (IBGs) instead of synchronous generators (SGs). Since IBGs have significant differences in their characteristics compared to SGs , particularly with regard to their inertia and capability to provide reactive power, their impacts on the system dynamics are different compared to SGs. A comprehensive review on voltage stability of power systems with the inclusion of inverter-based generators is presented.
