Global efforts are being undertaken to tackle climate change caused by global warming due to greenhouse gas (GHG) emissions. Canada has set ambitious goals of reducing GHG emissions to net-zero by 2050. To achieve this, fossil fuels must be replaced by non-GHG producing fuels, such as green hydrogen (H2). Currently, about 96% of H2 is produced from methane and other fossil fuels by reforming or gasification processes, resulting in high carbon intensity. Hence, other technologies, such as water and steam electrolysis capable of producing low carbon intensity H2 at large scale should be rapidly developed to meet the increased H2 demand in the coming decades. Current proton exchange membrane and alkaline electrolysis technologies require high purity water as the input. However, due to limited clean water sources, electrolysis technologies that product H2 from non-potable and sea water must be developed. To address these issues, Evolve Hydrogen Inc (EHI) is currently developing a versatile, compact, small-scale electrolyzer based on low manufacturing cost materials and construction methods, which can operate on salt-containing water supplies. Although working prototypes have been developed using a unique, low-cost polymer moulding technology, the EHI electrolyzer performance, efficiency, and durability still requires enhancement through focussed research. This will involve altering the composition of the anode and cathode through the use of additives to the polymer precursor, as well as surface doping methods. By taking advantage of the catalyst development and electrochemical expertise of the Birss group, and the injection molding expertise of Qualicase Ltd and Fidelity Machine and Mould Solutions, the performance of an electrolyzer prototype used to generate H2 from seawater will be significantly improved. By these means, the subsidiary, Evolve Hydrogen Canada (EHC), is targeting to produce 100,000s of units in Canada for domestic and export purposes. Developing such a market-ready electrolyzer by Calgary-based companies will complement Canada's role as a world leader in producing and handling energy resources, while at the same time accelerating the diversification of its energy sector through equitable job creation.

全球正在努力应对因温室气体（GHG）排放导致的全球变暖所引起的气候变化。加拿大制定了雄心勃勃的目标，即到 2050 年将温室气体排放量减少到净零。为了实现这一目标，必须用不产生温室气体的燃料（例如绿氢 (H2)）取代化石燃料。目前，约96%的氢气是通过重整或气化过程由甲烷和其他化石燃料生产的，导致碳强度较高。因此，应迅速开发其他技术，例如能够大规模生产低碳强度氢气的水和蒸汽电解技术，以满足未来几十年不断增长的氢气需求。目前的质子交换膜和碱性电解技术需要高纯水作为输入。然而，由于清洁水源有限，必须开发从非饮用水和海水中生产氢气的电解技术。为了解决这些问题，Evolve Hydrogen Inc (EHI) 目前正在开发一种基于低制造成本材料和施工方法的多功能、紧凑型小型电解槽，该电解槽可以在含盐供水中运行。尽管工作原型是使用独特的低成本聚合物成型技术开发的，但 EHI 电解槽的性能、效率和耐用性仍然需要通过集中研究来增强。 This will involve altering the composition of the anode and cathode through the use of additives to the polymer precursor, as well as surface doping methods.通过利用 Birss 集团的催化剂开发和电化学专业知识，以及 Qualicase Ltd 和 Fidelity Machine and Mold Solutions 的注塑专业知识，用于从海水中产生氢气的电解槽原型的性能将得到显着提高。通过这些方式，子公司 Evolve Hydrogen Canada (EHC) 的目标是在加拿大生产 100,000 个装置，用于国内和出口用途。卡尔加里公司开发这种面向市场的电解槽将补充加拿大作为能源生产和处理领域的世界领导者的角色，同时通过创造公平的就业机会加速其能源部门的多元化。
