“…One of the most important features of SyPaB can reach nearly theoretical product yields because selecting only required enzymes eliminates unnecessary pathways that consume a significant fraction of carbon and energy sources [35,36]. In addition, cell-free systems has usually much higher reaction rates than microbial fermentations because of faster mass transfer without cellular membrane and higher biocatalyst density without dilution effects from other biomacromolecules and their side reactions [2,3,31,37,38].

“…For high-power electricity users, carbohydrate can be converted to hydrogen followed by PEM fuel cells, such as sugar fuel cell vehicles or distributed electricity generators [3]. For low-power electricity users, sugars can be converted to electricity through enzymatic fuel cells, such as battery rechargers or portable electronics [3,38]. Solar energy is not really free because of the high hidden costs for its conversion, scale-up, and storage [52][53][54].…”

Abstract:The hydrogen economy presents an appealing energy future but its implementation must solve numerous problems ranging from low-cost sustainable production, high-density storage, costly infrastructure, to eliminating safety concern. The use of renewable carbohydrate as a high-density hydrogen carrier and energy source for hydrogen production is possible due to emerging cell-free synthetic biology technology-cell-free synthetic pathway biotransformation (SyPaB

Enzyme based bioelectronics have attracted increasing interest in recent years because of their applications on biomedical research and healthcare. They also have broad applications in environmental monitoring, and as the power source for portable electronic devices. In this review, the technology developed for fabrication of enzyme electrodes has been described. Different enzyme immobilisation methods using layered structures with self-assembled monolayers (SAM) and entrapment of enzymes in polymer matrixes have been reviewed. The performances of enzymatic biofuel cells are summarised. Various approaches on further development to overcome the current challenges have been discussed. This innovative technology will have a major impact and benefit medical science and clinical research, healthcare management, energy production from renewable sources.

Sustainable development requires balanced integration of four basic human needs -air (O 2 /CO 2 ), water, food, and energy. To solve key challenges, such as CO 2 fixation, electricity storage, food production, transportation fuel production, water conservation or maintaining an ecosystem for space travel, we wish to suggest the electricity-carbohydrate-hydrogen (ECHo) cycle, where electricity is a universal energy carrier, hydrogen is a clean electricity carrier, and carbohydrate is a high-energy density hydrogen (14.8 H 2 mass% or 11-14 MJ electricity output/kg)carrier plus a food and feed source. Each element of this cycle can be converted to the other reversibly & efficiently depending on resource availability, needs, and costs. In order to implement such cycle, here we propose to fix carbon dioxide by electricity or hydrogen to carbohydrate (starch) plus ethanol by cell-free synthetic biology approaches. According to knowledge in the literature, the proposed artificial photosynthesis must be operative. Therefore, collaborations are urgently needed to solve several technological bottlenecks before large-scale implementation.Keywords: artificial photosynthesis, biofuels, cell-free synthetic biology, climate change, CO 2 fixation, electricity storage, food production, hydrogen, ecosystem for space travel, water 3 Sustainable development is a pattern of resource use that aims to meet human needs while preserving the environment. As the human population grows and its needs and desires (e.g., food, energy) expand, the problem of sustaining civilization or even improving the quality of life is challenging for scientists and engineers.To address sustainability challenges associated with air, water, food, and energy, I propose to construct the electricity, carbohydrate, and hydrogen (ECHo) cycle (Fig. 1). In this cycle, electricity is difficult to store but it is a universal energy carrier that can be produced from nonrenewable primary energy sources (e.g., fossil fuels or nuclear energy) or renewable primary energy sources (e.g., solar, wind, biomass, etc.); hydrogen, a clean electricity carrier that can be converted to electricity by fuel cells with high efficiency and without pollutants, is difficult and costly to store and distribute; solid carbohydrate, which is a high-density hydrogen carrier and food source, can be easily produced, stored, and distributed.To implement the ECHo cycle, we must efficiently fix CO 2 in the form of carbohydrates with an energy input of electricity or hydrogen (Fig. 1). When these technologies are developed, we can address the below a number of challenges associated with sustainability: (i) fixing CO 2 to mitigate climate change, (ii) producing food from CO 2 and water through artificial photosynthesis, (iii) generating sustainable transportation biofuel from CO 2 and electricity, (iv) storing electricity as a form of chemical compound(s) on a large scale, (v) conserving water as compared to natural plant photosynthesis, (vi) storing hydrogen in the form of carbohydrate a...
