Hydrogen production for energy: An overview

open access: yes, 2020
Power to hydrogen is a promising solution for storing variable Renewable Energy (RE) to achieve a 100% renewable and sustainable hydrogen economy. The hydrogen-based energy system (energy to hydrogen to energy) comprises four main stages; production ...

Production, use, and fate of all plastics ever made

open access: yesScience Advances, 2017
We present the first ever global account of the production, use, and end-of-life fate of all plastics ever made by humankind. Plastics have outgrown most man-made materials and have long been under environmental scrutiny.

A Pacific interdecadal climate oscillation with impacts on salmon production

open access: yesOceanographic Literature Review, 1997
Evidence gleaned from the instrumental record of climate data identifies a robust, recurring pattern of ocean–atmosphere climate variability centered over the midlatitude North Pacific basin.

Measurement of the differential isolated prompt photon production cross section in p p collisions at 7-TeV center-of-mass energy

open access: yesProceedings of XXIst International Europhysics Conference on High Energy Physics — PoS(EPS-HEP2011), 2012
In this paper we present two measurements : the measurement of the differential cross section for the inclusive production of isolated prompt photons [1], and the measurement of the production of pairs of prompt isolated photons [2] in proton-proton ...

Primary production of the biosphere: integrating terrestrial and oceanic components

open access: yesScience, 1998
Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, with roughly equal contributions from land and oceans ...

Yield Trends Are Insufficient to Double Global Crop Production by 2050

open access: yesPLoS ONE, 2013
Several studies have shown that global crop production needs to double by 2050 to meet the projected demands from rising population, diet shifts, and increasing biofuels consumption. Boosting crop yields to meet these rising demands, rather than clearing

Hydrogen production from water electrolysis: role of catalysts

open access: yesNano Convergence, 2021
As a promising substitute for fossil fuels, hydrogen has emerged as a clean and renewable energy. A key challenge is the efficient production of hydrogen to meet the commercial-scale demand of hydrogen. Water splitting electrolysis is a promising pathway

Hydrogen production by PEM water electrolysis – A review

open access: yes, 2019
Hydrogen is the most efficient energy carrier. Hydrogen can be obtained from different sources of raw materials including water. Among many hydrogen production methods, eco-friendly and high purity of hydrogen can be obtained by water electrolysis ...
