To achieve the SDGs, the world should transition towards a more sustainable economy based on (i) decarbonization across sectors of the economy; (ii) greater reliance on renewable energy; and (iii) sustainable production, consumption, packaging, and waste disposal. These transitions could provide developing countries with green windows of opportunity (GWO) for technological catch up and leapfrogging, economic diversification, and sustainable and inclusive growth.

UNCTAD will discuss these issues in depth in its next Technology and Innovation Report. As part of a pre-publication consultation process, UNCTAD, in collaboration with the Global Solutions Summit (GSS), plans to convene a series of workshops, each one devoted to a specific GWO. The side event at the 2022 STI Forum was the first in this series and focused on green hydrogen programs.

This side event highlighted policies and programs that will enable countries to exploit a specific green window of opportunity on green hydrogen, so that participants will have a clearer understanding of the wide range of issues that should be considered to develop GWO roadmaps tailored to each countries unique circumstances.

Presentation: Green windows of opportunities, Mr. Rasmus Lema, Associate Professor, UNU-MERIT, co-editor in chief of the journal Innovation and Development and vice-chairman of the Globelics Scientific Board

In this age of green-cleaning and natural everything, hydrogen peroxide is a great option for not just cleaning but disinfecting your windows and mirrors. Disinfect windows? I hear you ask, incredulously. Well, windows spend their entire life exposed to the elements, attracting not just dust, dirt and grime, but the mass suicide of insects and small flying creatures. The result is a delightful mash-up of visible and invisible lifeforms, smeared comprehensively across your window panes. Hydrogen peroxide to the rescue! Below is our easy, three-step guide to disinfecting your windows with hydrogen peroxide. If your windows are diabolically dirty, follow our guide to cleaning them first:

Hydrogen value chains, beingdigitally interconnected, can help to minimizerisks and optimizecosts right from the start. An efficient green hydrogeneconomy, digital interconnectedness and dataanalyses create required synergies. TheCibusCell cloudsolution enables cross-sectoral alignment,paving the way for an efficient green hydrogen economy. The software solution enables marketplayers to set project investments on a solid footing right from the start.

Hydrogen will play a crucial role in the mounting global efforts to decarbonize our economic systems in the coming decades. Many developing countries have the potential to influence the hydrogen economy, which may provide one-fifth of total energy demand by 2050, especially in those areas that are difficult to electrify. This opens green windows of opportunity for economic development and diversification. Green hydrogen could decarbonize sectors of the economy and promote equitable growth, notably for developing countries that seize the green window of opportunity.

Green hydrogen is a key technology for energy and industrial systems of the future and will allow for the greening of hard-to-abate sectors such as steel, cement, aluminium, chemicals, long-haul transportation, aviation, etc. However, green hydrogen is generally expensive, usually more so than grey hydrogen (produced with fossil fuels), although at this moment, it is cheaper in Europe, the Middle East and China due to the fossil fuel price spike caused by the Ukraine war. IRENA, the International Renewable Energy Agency, expects that green hydrogen will reach general price parity with blue hydrogen, fossil fuels hydrogen with carbon and capture and storage, gradually over the next 10 to 15 years. This is because the cost of renewables is decreasing, and carbon taxes will further raise the price of fossil fuels. IRENA predicts that hydrogen from low-cost wind and solar will reach price parity at 2.5 a kilo within a few years. Competitive prices will speed up the formation of hydrogen economies and increase global demand.

Green hydrogen is thus an important opportunity stemming from the expected development of a significant demand window and factor endowments with enormous potential for renewables in large parts of the Global South. There is a clear opportunity for many developing countries with large renewable resources to become net exporters. This opportunity could be supported by further scaling-up developments fuelled by technological improvements and innovations in the value chain, better transportation and longer storage time.

In terms of backward links, green hydrogen comes from renewables. The opportunity is to invest in such renewables and their supply chains. When transformed to green hydrogen, renewable energy output can be exported in circumstances where domestic supply exceeds domestic demand and provided the requisite infrastructure is in place. In terms of the core green hydrogen technology, the opportunity is to invest in technology to transform electricity energy outputs to hydrogen and further to derivative feedstocks such as ammonia and methanol. This requires investment in electrolysers and infrastructures such as pipelines and ports, and technology to transform hydrogen into fuels and fertilizers, which can be more easily transported and traded. There are different political strategies for managing this. One is to rely on foreign investors and technology suppliers. Another is to encourage investment in local technological capabilities and innovation systems. Over time, this can lead to the capacity to export electrolyser and conversion technology in foreign markets. In terms of forwarding linkages, a substantial green hydrogen capacity opens new opportunities in other sectors across industry, transport and agriculture including in the production of hydrogen-based outputs such as low-carbon steel and low-carbon cement which generates opportunities for competitiveness in decarbonized production.

The basis of the system is the renewable energy sector (wind, solar, geothermal, hydro), which should be in place for green hydrogen. The second wave is associated with industries transforming renewable energy into green hydrogen. These are related to electrolysers, feedstock industries (ammonia, methanol, and liquid organic hydrogen carriers), and infrastructure (pipelines, ports, tank ships and desalination plants). The third wave of industries that use the feedstocks, such as iron and steel, chemicals and transport (synthetic aviation fuels, fuel cells). The fourth wave is with downstream sectors such as auto, fertilizers and pharmaceuticals.

This requires strategic thinking and coordination capacity to capitalize on favourable preconditions and associated opportunities and connect the green hydrogen initiative via backward linkages to renewables, and forward linkages to industry, transport and agriculture.

Several developing countries are already taking action to exploit green hydrogen. They seek to bring together a large array of stakeholders with mission-oriented programmes for the hydrogen economy. The strong inter-industrial linkages, where green hydrogen is at the core of the industrial web, creates an enormous demand for cross-sector coordination. Joint design of policies for relevant sectoral production and innovation systems are needed as forward and backward linkages connect to highly different domains.

In Cear, Brazil, the start government has prioritized green hydrogen in its long-term state plan, Cear 2050, along with a commitment to a fair energy transition. Characterized by good location, Cear positions itself as a Green Hydrogen Hub, with strong conditions for renewable energy production, water supply, and a growing green hydrogen value chain. The State government expects to bring value to society, improve production chains, and increase human capital.

Green hydrogen is still an immature technology that is undergoing a fast-paced change with considerable uncertainty. The initial elements of the technological ecosystem of green hydrogen are capital intensive and developing countries will therefore benefit (or even require) collaboration with R&D and technology centres to deploy the technology. There are still big uncertainties about technologies and markets, and a significant challenge is currently the global tradability of green hydrogen in sea vessels which requires further technical development. Investments in water salination facilities are another core challenge.

The Hydrogen Line is an observable increase in RF power at 1420.4058 MHz which is created by Hydrogen atoms. It is most easily detected by pointing a directional antenna towards the Milky Way as there are many hydrogen atoms in our own galaxy. This effect can be used to measure the shape and other properties of our own galaxy.

As a recent IPCC report warns, we will face catastrophic global warming unless we decarbonize vast sectors of the economy. The IPCC also notes that green hydrogen will be an indispensable ingredient for successful decarbonization. For developing countries, therefore, the critical question is will they be left behind or can they capitalize on these green windows of opportunity to generate sustainable, inclusive growth and prosperity?

Neither workshop offered definitive answers to all the outstanding questions about transforming the food system and exploiting green hydrogen and other green windows of opportunity. But they both provide an important starting point for understanding both the challenges at hand and the opportunities that beckon.

Solvent-suppression NMR techniques are combined with a pulsed magnetic field gradient and surface coil detection method of spatial localization. The result is a technique that enables observation of metabolites in the hydrogen (1H) NMR chemical-shift spectra from preselected disk-shaped volumes of biological tissue in vivo. Localized spectra are recorded from the normal human brain and forearm and from a dog in acquisition periods of 2 s using a 1.5-T imaging/spectroscopy system. This is several hundred-fold faster than acquiring similar state-of-the-art 31P NMR spectra of brain metabolites in vivo. Spectroscopy experiments are followed by conventional surface coil imaging sequences to precisely define the selected volume. Contamination of spectra by lipid resonances is a problem. 17dc91bb1f
