We describe an approach to CO 2 capture and storage from the atmosphere that involves enhancing the solubility of CO 2 in the ocean by a process equivalent to the natural silicate weathering reaction.
HCl is electrochemically removed from the ocean and neutralized through reaction with silicate rocks. On timescales of hundreds of years or longer, some of the additional alkalinity will likely lead to precipitation or enhanced preservation of CaCO 3resulting in the permanent storage of the associated carbon, and the return of an equal amount of carbon to the atmosphere.
Whereas the natural silicate weathering process is effected primarily by carbonic acid, the engineered process accelerates the weathering kinetics to industrial rates by replacing this weak acid with HCl. In the thermodynamic limit—and with the appropriate silicate rocks—the overall reaction is spontaneous.
A range of efficiency scenarios indicates that the process should require — kJ of work per mol of CO 2 captured and stored for relevant timescales. The process can be powered from stranded energy sources too remote to be useful for the direct needs of population centers.
It may also be useful on a regional scale for protection of coral reefs from further ocean acidification. Application of this technology may involve neutralizing the alkaline solution that is coproduced with HCl with CO 2 from a point source or from the atmosphere prior to being returned to the ocean.

Rivals in the scramble to be the world’s 21st-century superpower
Sincethe United States has left the Paris accord and reports from around the world show that countries are not moving fast enough to hit those targets. More than ever before, individual actions —including mobilizing for political transformation—can make a difference.
Curbed searched communities across the country and around the world, consulted experts and advocates, and pulled from our voluminous coverage on sustainable cities to create a go-to guide for climate action.
Our goal is to provide practical, implementable advice on an individual level, as well as to illustrate the power of collective commitments. Think of it as your must-do action plan for this year, and every other year. Add solar panels to your house. With the plunging price of solar power, and an increasingly diverse group of companies such as Tesla and Forward Labs offering new products, the toughest decision may not be whether to install, but which style and color panels to place on your roof.
Get a home energy audit. A simple home energy audit can show how much energy your home consumes and give you tips on changes that can make things more efficient. Change lightbulbs to LEDs. Quality LED lightbulbs can last 25 times longer, are more durable, and use at least 75 percent less energy than other bulbs. In the United States, widespread use of LEDs over the next 10 years could save the equivalent annual electrical output of 44 large power plants about TWh.
Ask your utility company about buying clean electricity. You may not know exactly how much of your electricity is coming from renewable energy, so now is the time to find out. Clean or replace HVAC filters every three months. A dirty filter on your air conditioner or heater will make the system work harder and waste energy. Use a programmable thermostat. Wash clothes in cold water.A flow batteryor redox flow battery after reduction—oxidationis a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane.
Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1. A flow battery may be used like a fuel cell where the spent fuel is extracted and new fuel is added to the system or like a rechargeable battery where an electric power source drives regeneration of the fuel. While it has technical advantages over conventional rechargeables, such as potentially separable liquid tanks and near unlimited longevity, current implementations are comparatively less powerful and require more sophisticated electronics.
The energy capacity is a function of the electrolyte volume amount of liquid electrolyteand the power is a function of the surface area of the electrodes. A flow battery is a rechargeable fuel cell in which an electrolyte containing one or more dissolved electroactive elements flows through an electrochemical cell that reversibly converts chemical energy directly to electricity electroactive elements are "elements in solution that can take part in an electrode reaction or that can be adsorbed on the electrode" .
Additional electrolyte is stored externally, generally in tanks, and is usually pumped through the cell or cells of the reactor, although gravity feed systems are also known.
In other words, a flow battery is just like an electrochemical cellwith the exception that the ionic solution electrolyte is not stored in the cell around the electrodes. Rather, the ionic solution is stored outside of the cell, and can be fed into the cell in order to generate electricity. The total amount of electricity that can be generated depends on the size of the storage tanks. Flow batteries are governed by the design principles established by electrochemical engineering.
Various types of flow cells batteries have been developed,  including redoxhybrid and membraneless. The fundamental difference between conventional batteries and flow cells is that energy is stored in the electrode material in conventional batteries, while in flow cells it is stored in the electrolyte.
The redox reduction—oxidation cell is a reversible cell in which electrochemical components are dissolved in the electrolyte. Redox flow batteries are rechargeable secondary cells. The performance of a solid-state battery depends on the diffusion of ions within the electrolyte, solid electrolytes must have high ionic conductivity, very low electronic conductivity and a high degree of chemical stability.
Examples of redox flow batteries are the Vanadium redox flow batterypolysulfide bromide battery Regenesysand uranium redox flow battery. Vanadium Redox Flow Batteries are the most marketed flow batteries at present, due to a number of advantages they present on other chemistries, despite their limited energy and power densities. Since they use vanadium at both electrodes, they do not suffer cross-contamination issues. For the same reason, they have unparalleled cycle lives 15,—20, cycleswhich in turns results in record levelized cost of energy LCOE, i.
One unresolved issue is zinc build-up on the negative electrode that permeated the membrane, reducing efficiency. Adding alcohol to the electrolyte of the ZnI battery can slightly control the problem. The battery produces power by pumping liquid from external tanks into the battery's stack area where the liquids are mixed. Inside the stack, zinc ions pass through a selective membrane and change into metallic zinc on the stack's negative side.Climate Change Weekly A key mechanism for fighting climate change, some environmental activists and politicians say, is to increase the amount of electricity produced from renewable sources that do not emit carbon dioxide CO2.

As nearly everyone knows, a key problem with wind and solar power is their intermittency, which makes those power sources difficult to accommodate in the electric grid. The intermittency burden increases as the percentage of renewable sources contributing to the grid is increased. Pumped hydro storage PHS is widespread and efficient where suitable, affordable terrain hilly or mountainous regions with a regular water supply is available.
Most electrical grids in developed countries already have taken advantage of PHS to the extent they can, including supporting renewable power generation in the alpine regions of Austria, Germany, and Switzerland. Neither can store enough energy for bulk wind and solar needs. Chemical energy storage is even more expensive and less efficient than battery power. Only experimental systems exist.
It is very unlikely that any grid storage solution other than PHS where feasible could ever practically cover the intermittency of high penetration utility scale wind and solar. With the Federal Reserve estimating just 1.Rx 590 multiple monitors
The growth is expected to accompany record trade surpluses for the industry by Fracking released abundant and cheap natural gas and natural gas liquids NGLsincluding ethane, which are key feedstocks and fuel for the chemical industry. Less than a decade ago, the domestic chemical industry was in decline as natural gas prices were high and estimated reserves low.
Chemical manufacturing was moving overseas. All that has changed in response to the low gas prices brought about by the fracking revolution. ACC reports U. With estimates of human population consistently topping 9 billion people, requiring a doubling of food production, research scientists Sherwood, Craig, and Keith Idso say the human-induced increase in atmospheric carbon dioxide will be a good thing.Masiello, guido
The Idsos estimate world food production will be only 37 percent greater relying solely on anticipated improvements in agricultural technology. But risking carbon dioxide levels can overcome the shortfall. Not only is carbon dioxide a plant fertilizer, increasing the total biomass and vegetable, seed, and fruit production, but it also reduces water loss through transpiration. This is critical because, as researcher Jim S.
Wallace noted inincreased food production will require more, and more efficient, water use.Metal-air is a promising battery system that uses inexpensive metals for its negative electrode while unlimited, free and non-toxic oxygen is used for its positive electrode, however, only primary systems have been commercialized so far.
