“…One of the crystals, like KAP/Si111/Si220/Si440, can be installed and replaced on the monochromator so as to cover 1∼40 keV. As Figure 8 shows, this source has been successfully Article Title applied in the energy response calibration of the CCD236 detector of the Low Energy Telescope onboard HXMT [14]. To calibrate the timing performance of the detector and telescope system, a modulated X-ray source was developed [15] and verified.…”

The 100-m X-ray Test Facility of the Institute of High Energy Physics (IHEP) was initially proposed in 2012 for the test and calibration of the X-ray detectors of the Hard X-ray Modulation Telescope (HXMT) with the capability to support future X-ray missions. The large instrument chamber connected with a long vacuum tube can accommodate the X-ray mirror, focal plane detector and other instruments. The X-ray sources are installed at the other end of the vacuum tube with a distance of 105 m, which can provide an almost parallel X-ray beam covering 0.2∼60 keV energy band. The X-ray mirror modules of the Einstein Probe (EP) and the enhanced X-ray Timing and Polarimetry mission (eXTP) and pay-load of the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) have been tested and calibrated with this facility. It has been also used to characterize the focal plane camera and aluminum filter used on the Einstein Probe. In this paper, we will introduce the overall configuration and capability of the facility, and give a brief introduction of some calibration results performed with this facility.

“…[10,11] To address today's energy market needs for sustainability in industry and transportation, "Green Hydrogen" produced from renewables plays a pivotal role in decarbonization. [12][13][14] In addition to these developments in industry, there are also various lab-based efforts worldwide including, plasmolysis of water/water vapors, reforming of alcohols, biohydrogen (based on microalgae), or chemical cycles [15][16][17][18][19][20] There is no doubt that hydrogen is one of the key tools in energy transition, and it has a very significant effect on CO 2 emission reductions (6%) according to NZE Scenario. IEA reported in the Global Hydrogen Review that ≈90 Mt H 2 was produced worldwide in 2020, where 80% of this amount was produced from fossil resources.…”

Hydrogen plays an essential role in the energy‐transition process. Even though currently almost 80–96% of hydrogen is produced from fossil fuel sources in the world, the exciting feature of hydrogen is that it can be produced from renewable sources by splitting water molecules through electrolyzing, and then it can be re‐electrified without any emissions by‐products. Hydrogen is the secondary source of energy as well as an energy carrier that stores and transports the energy produced from other sources such as water, biomass, and fossil fuels. It is a clean‐burning fuel; when oxidized in a fuel cell, it produces heat, electricity, and water vapor as a by‐product, without any carbon emissions. Despite these exciting characteristics of hydrogen, there are still a variety of challenges, such as cost‐effective hydrogen production and its technological challenges, storage, safety, transportation, and cost issues. This article aims to overview the challenges and opportunities in hydrogen production, storage, and transportation along with some future perspectives on hydrogen.
