So how about hearing about some measures that will help us deal with the fact that we now have a growing climate crisis on our hands, and that we urgently need to slow the rate at which we are pumping CO2 into the atmosphere to help the earth get hotter faster?
A couple of urgent needs require ways of dealing with them:
1. How can we deal with the fact that there are many purposes for which a gas that burns is extremely convenient, but it is a bad idea to burn cases that produce CO2 as a combustion product, like natural gas or coal gas?
2. How can we find a way of storing electrical energy from renewable energy sources that vary in their power output depending on environmental conditions?
At the
Earthshot Prizes award ceremony in London last night, five prizes were awarded to projects judged to be 'the most innovative solutions to the greatest environmental challenges facing our planet'. Each winner gets USD 1 million in funding, plus access to 'a global network of professional and technical support to scale these cutting-edge environmental solutions'.
One of the prizes went to a project that offers solutions to both the needs above, by producing clean hydrogen gas using renewable electricity to electrolyse water (i.e. it takes the H2O molecule of water, and splits it apart into its component parts of hydrogen and oxygen), and the only combustion product is water. Burning hydrogen in air gives you a flame temperature of around 2000 centigrade, slightly hotter than a butane/propane mix. And of course you can easily store the resultant gas for later use, either by burning it or using it to drive an internal combustion engine for mechanical power generation (maybe in a vehicle), or getting electrical output by passing the stored hydrogen through a fuel cell,
AEM ELECTROLYSER
Born in a climate-change affected South Pacific Island, Vaitea Cowan co-founded Enapter to turn back the tide. Just three years on, its green hydrogen technology could change the way we power our world.
We have made huge advances in renewable energy. But we can still go further. With 30% of our energy already renewable, we need to focus on the 70% that remains: non-renewable energy that powers everything from industry to transport.
Enapter provides a clean alternative. Its AEM Electrolyser technology turns renewable electricity into emission-free hydrogen gas. Developed quicker and cheaper than once thought possible, the technology already fuels cars and planes, powers industry and heats homes.
This is just the start. Funding from winning The Earthshot Prize would help scale mass production, which is planned to begin in 2022, while growing the team faster and funding further research and development. By 2050, Enapter’s vision is to account for 10% of the world’s hydrogen generation.
Enapter shows us that, when faced with the greatest of challenges, we can turn back the tide.
The main website of the project is
HERE - as you can see they have already been successful in marketing their units to a wide variety of customers. This is not just somebody's bright idea: this is already working practically and commercially. And the basic materials are simply water, and sunshine or wind.
