The prospects for renewable energy are enhanced through the use of hydrogen energy systems in which hydrogen is an energy carrier. As easily accessible fossil fuel supplies become scarcer and environmental concerns increase, hydrogen is likely to become an increasingly important chemical energy carrier. As the world’s energy sources become less fossil fuel-based, hydrogen and electricity are expected to be the two dominant energy carriers for the provision of end-use services, in a hydrogen economy. Thus, hydrogen energy systems allow greater use of renewable energy resources. In this presentation, the role of hydrogen as an energy carrier and hydrogen energy systems, and their economics, are described and reviewed.
There are many commercial processes for producing hydrogen from fossil fuel and non-fossil fuel sources (including renewables). Technologies for the storage and distribution of hydrogen exist. Technologies are developing for utilizing hydrogen as an energy carrier, especially in transportation. The technologies needed for hydrogen energy systems are undergoing much research and development.
City University of Hong Kong, Hong Kong SAR, China

He also contributes to many reputable international conferences as committee members and invited speakers. He holds fellow membership in many professional institutions, such as FASHRAE and FCIBSE
The interest in zero carbon building developments is increasing year by year. This makes it important to maximize the renewable power outputs and thus favors the use of hybrid generating systems. Combined active and passive solar design is an evolving science in building technology. Traditionally, building facade is one crucial element in architecture. Nowadays, it has escalating importance in services engineering owning to its significant influence on the engineering system performance and energy use. Building integrated solar devices may be installed either at the building façade or on the roof. The system can be designed as invisible, aesthetically appealing, or appearing as an architectural concept. Advances in the development of multi-functional photovoltaic/thermal (PV/T) facades may provide an important stimulus for architectural expression. On the other hand, the design of extensively-glazed building is a world-wide architectural trend. At this end, the PV ventilated glazing technology offers substantial energy saving opportunities through air conditioning load reduction, more favorable daylight penetration, and solar energy utilization. On the other hand in the liquid-flow window option, a thermosyphon-induced liquid stream flows within the cavity to the heat exchanger for feed water pre-heating. The building integrated active and passive solar designs then ask for the consideration of all building components and services systems at one shot, well at the project commencement stage. In other words, site planning, aesthetic design, system equipment and construction material selection, financing, construction, commissioning, and long term operation and maintenance have to be well coordinated. These become alternative challenges to be overcome.

Do we need energy or exergy? Amount of exergy in energy carriers is very different and prices include value of quantity and not the quality of energy. Exergy is measure for quality of energy, because the only part of energy available to do work is exergy. For different purposes we need energy with different amount of exergy: for heating and cooling energy mixture between small amount of the exergy and large part anergy is needed. Transition to sustainable energy system, without GHG emissions, based on RE, open the questions how to evaluate exergy from solar energy. Solar energy in all form (irradiation, water flows, wind, and biomass) consists from nearly 100% of exergy. Solar energy is for free, conversion systems are not. To exploit at maximum the present infrastructure there is common agreement that we need sustainable energy system with four main energy carriers: electricity, gaseous, liquid and solid fuels.
Our vision is the new Sustainable Energy System (SES) based on the biomass carbon recycling using solar and planetary energy for electricity and hydrogen production. SES is based on the existing infrastructure and known chemical processes. With regards to availability of renewable energy resources (RES) it is unrestricted in comparison to present fossil fuels use. The proposed SES consists of the three main energy carriers: electricity, synthetic methane (CH4) and synthetic methanol (CH3OH).
