Bridge System

<p>This paper presents a novel ecological &amp; energized modules (EEMs) system for transportation and bridge systems. It has a general interest in almost all human living &amp; ecological systems, civil engineering, and infrastructure. As an underlying and fundamental system of zero energy, zero- water-consumption, and zero-carbon with a 100% greening rate and 100% clean energy, high- quality air, and powerful carbon capture system with significant positive spillover for global carbon removal and climate challenges, etc., the EEMs bridge system is easy, fast, efficient, and zero- dependence on the large complex equipment during the construction. It is applied to a wide variety of bridge systems, such as road bridges, footbridges, flyovers, and overpasses. It’s pollution-free, safe, noiseless, and can be used soon after paving, repairing, and re-laying. The EEMs bridge system has unique superiority in ecosystem integrity and connectivity, resulting in available consequences for global biodiversity, local species interactions, ecosystem integrity and connectivity.</p>

Global Carbon Market

ABSTRACTThis study uses a global climate-energy-economy model to investigate potential implications of linking credits from reducing emissions from deforestation and forest degradation in developing countries to a global carbon market, focusing on reducing emissions from deforestation (RED) and effects on energy technology innovation. Integrating RED into a global carbon market lowers the estimated total costs of a policy to achieve 535 ppmv of CO2-equivalent concentrations in 2100 by up to 25 per cent. Alternatively, a global RED program could enable additional reductions of about 20 ppmv by 2100 with no added costs compared with an energy-sector-only policy. The results indicate that market linkage of RED induces modest reductions in clean energy innovation overall but slightly enhances development of particular technologies, including carbon capture and storage. We also find that RED in combination with credit banking encourages greater mitigation in the near term, enhancing flexibility to potentially tighten emission targets at lower cost in response to future information.

Do So

Many nations have committed to midcentury net zero carbon emissions targets in line with the 2015 Paris Agreement. These require systemic transition in how people live and do business in different local areas and regions within nations. Indeed, in recognition of the climate challenge, many regional and city authorities have set their own net zero targets. What is missing is a grounded principles framework to support what will inevitably be a range of broader public policy actions, which must in turn consider pathways that are not only technically, but economically, socially and politically feasible. Here, we attempt to stimulate discussion on this issue. We do so by making an initial proposition around a set of generic questions that should challenge any decarbonisation action, using the example of carbon capture and storage to illustrate the importance and complexity of ensuring feasibility of actions in a political economy arena. We argue that this gives rise to five fundamental ‘Net Zero Principles’ around understanding of who really pays and gains, identifying pathways that deliver growing and equitable prosperity, some of which can deliver near-term economic returns, while avoiding outcomes that simply involve ‘off-shoring’ of emissions, jobs and gross domestic product.

The present study investigates macrofouling development in the Mar Grande of Taranto (Central Mediterranean Sea), a wide confined area that has attracted considerable attention in recent years due to the establishment of numerous non-indigenous species (NIS). Different starting times of a yearly primary succession on artificial substrates were tracked so as to investigate the matching of the development pattern with contingency and/or convergence models, identifying NIS’s structural role in the community endpoint. Our results show that during the experiment all assemblages tended to converge towards multiple contingent communities according to starting times and depths. The differences are due to propagule availability which influence further species interactions. Thus the endpoint patterns are defined by a contingent community development determined by the seasonal species pool, their phenologies, pre- and post-settlement events, and species interactions. The most important structuring species was Mytilus galloprovincialis, which was present in almost all the endpoint assemblages, in particular when it recruits at early stages of the community development. Another abundant species at the endpoint was the alien Branchiomma boholense; which was a persistent structural component contributing to an alternative state in which Mytilus galloprovincialis loses its structural importance and where B. boholense becomes dominant, leading to an increase in fouling biodiversity of the endpoint assemblage.

Green pivot: can Australia master the hydrogen trade?

Australia is in a bind. It is at the heart of the pivot to clean energy: it contains some of the world’s best solar irradiance and vast potential for large-scale carbon capture and storage; it showed the world the path forward with its stationary storage flexibility at the much vaunted Hornsdale power reserve facility; and it moved quickly to capitalise on low-carbon hydrogen production. Yet it remains one of the largest sources for carbon-intensive energy exports in the world. The extractive industries are still delivering thermal coal for power generation and metallurgical coal for carbon-intensive steel making in Asian markets. Even liquefied natural gas’s green credentials are being questioned. Are these two pathways compatible? The treasury and economy certainly benefit. But there is a huge opportunity to redress the source of those funds and jobs, while fulfilling the aspirations to reach net zero emissions by 2050. In our estimates, the low-carbon hydrogen economy could grow to become so substantial that 15% of all energy may be ultimately ‘carried’ by hydrogen by 2050. It is certainly needed to keep the world from breaching 2°C. Can Australia master the hydrogen trade? It is believed that it has a very good chance. Blessed with first-mover investment advantage, and tremendous solar and wind resourcing, Australia is already on a pathway to become a producer of green hydrogen below US$2/kg by 2030. How might it then construct a supply chain to compete in the international market with established trading partners and end users ready to renew old acquaintances? Its route is assessed to mastery of the hydrogen trade, analyse critical competitors for end use and compare costs with other exporters of hydrogen.

Fossil Fuel Energy

CCS (Carbon Capture and Storage) is the only technology available to achieve a deep cut in CO2emissions from large-scale fossil fuel usage. Although Guangdong Province has less heavy industries and higher reliance on energy import compared with many other provinces in China, CCS is still essential for the low-carbon development in the province. This is because fossil fuel energy is now and will be in the foreseeable future the major energy in Guangdong. CCS may have other benefits such as helping energy security and bring new business opportunities. The feasibility of CCS development in Guangdong is ensured by the existence of sufficient CO2storage capacity in offshore sedimentary basins in the northern South China Sea. A safe CO2storage is achievable as long as the selection of storage sites and the storage operations are in restrict quality control. The increased cost and energy penalty associated with CCS could be reduced through technical R&D, the utilization of captured CO2, and the utilization of infrastructure of offshore depleted oil fields. Fossil fuel energy plus CCS should be regarded as a new type of clean energy and deserves similar incentive policies that have been applied to other clean energies such as renewables and nuclear.
