Evolutionary development of Clan Elementals.
It was not until 2410 that General Mechanics succeeded in developing the first viable industrial exoskeletons. Though they would be used extensively throughout known space, they were not suitable for deployment as combat units.
but secret development of power armor resulted in the Mark XXI Nighthawk in 2718. The Nighthawk was deployed in Royal Infantry Divisions and the Special Forces Command.
The deployment of the Nighthawk was never made public
Though concentrated on Mechs and aerospace development, the strides made by Clan scientists would also have a profound impact on infantry.The origins of modern battle armor can be traced back to the pressurized diving units developed by Clan Goliath Scorpion for use in exploiting the resource-rich oceans on the planet Dagda.This proto-armor featured myomer musculature,self contained air-supply and life-support systems, and heavy, atmospherically sealed bodies designed to withstand the high pressures of deep-sea work.When Clan Wolf observed these suits in use, they quickly realized their combat potential.Consequently, the Wolves obtained a few of the suits and set about adapting them for combat by adding armor, weapons and small jump jets.

Not an engineer here, but using wiki, deep sea mining on earth is done between 1.4km to 3.7 km.

So, the initial Clan Goliath suits were able to withstand pressures of that depth and function as a form of survival/mining gear.
Nicknamed "water elementals" by their labor-er-caste operators, the suits sported monstrously shaped titanium hulls and mounted a large-bore drill and grasping claw.
Variant armor fielded by other Clans led Scorpion scientists to devise a suit tailored to an underwater environment. As it turned out, the modifications were fairly simple, due in part to the fact that Elemental suits evolved from undersea exoskeletons. The most difficult challenge was to equip this suit with appropriate weaponery for its mission,

There is no evidence to suggest that Clan Elementals retain the ability to withstand the pressures involved in deep sea operations, although the above quote suggests that they are still able to operate underwater. Instances of this can be derived from Clan Wolf operations against Jade Falcons, where elementals have accompanied Battlemechs in underwater riverine crossing.
Early versions of Clan battle armor were tailored to specific combat roles and environments. Clan Wolf perfected the battlesuit known as Elemental battle armor, a compromise between the various types that was designed to function equally well in any environment and on virtually any type of mission. None of the earlier versions could match the Wolf suit's versatility, and so they faded into obscurity as Elemental battle armor gained wide acceptance among all the Clans.

The reasons why Clan Wolf suit won out over other types of battle armor. It is also interesting to note the spread of technology and later stasis in this era. The popularity of the multi-role Elemental was so much that development in Battle armor stagnated until the Inner Sphere developed other models of Battle armor. Similarly, the Clans possessed means of spreading technology around if they wanted so, through both trade and Trials of Possession, including the political wrangling involved.
For example
The Wolves first deployed their new battle armor in 2868.Later that year, the Wolves faced off against Clan Hell's Horses in a series of Trials. Hell's Horses had been breeding genetically enhanced conventional infantry troops, later called Elementals. After the Trials were concluded, the Horses had obtained battle armor technology and the Wolves had obtained the knowledge needed to create their own Elementals. Almost immediately, the two Clans initiated the tradition of matching Elemental troops with battle armor. Within a short period of time, battle armored Elemental troops were deployed throughout Clan forces.

In a series of pre-arranged trials, both Clan Wolf and Hell Horses squared off in a series of "fixed" matches so that each could obtain what it wanted. We simply do not know why both Clans did not simply trade the technology. Perhaps such revolutionary changes in the Touman required a trial of arms to complete.
Straightforward sale of military resources, from Harjel to Battlemechs/Omnimechs have occurred before, indeed, the sale of equipment to the Invading Clans in return for resources from the Inner Sphere help accounts for their revivial post Tukayyid. ON the other hand, HarJel is often noted to be a resource that Trials of Possession are launched for.
Ultimately, this could be a simple case of politics. Which side brought home the bacon so as to speak. The Warriors caste or the Merchant caste. Another example of how the political wrangling between caste powers, along with inter-clan/inter warriors induces both strife and competition amongst the Clans.
Clan Wolf initially developed several suits, each tailored to specific environments, and the discovery of HarJel by Clan Diamond Shark(previously named Clan Sea Fox) enhanced the resilience of the suits even more. However, the Wolves soon opted for general-purpose battle armor suited to most battle-field conditions. The Clan battle armor fielded during Operation Revivial(the Clan invasion of the Inner Sphere) differed little from the original Wolf design.

In 2842, Goliath Scorpion scientists developed an enclosed industrial exoskeleton to aid underwater mining efforts on Dagda.

Pace of Clan Wolf R&D efforts. Within 4 years, Clan Wolf was able to notice Goliath technology, acquire and then introduce multiple specific environment/mission suits(an unknown number) along with at least one variety of GP battle armor. Matching with Elemental genetically engineered infantry and HarJel occured within the next few years and this combination of technology spread throughout the Clans in a "few years".
And just to end things up.
Battle armor manufacturing requires access to materials that are somewhat scarce on the resource-poor Clan worlds, but are more abdundant(given the significantly greater number of developed worlds) in the Inner Sphere.Posession of captured Inner Sphere planets has allowed the Invading Clans to step up battle armor manufacturing to the point where the expansion of their battle armor formations is only limited by the availability of suitable personnel. Even second-line formations are receiving new suits rather than the hand-me-downs they previously had to work with. The Diamond Sharks have been quick to move inon a lucrative market, trading excess Jade Falcon and Ghost Bear battle armor for advanced Home Clans technology, such as the advanced tactical missile system and heavy lasers.
Other sources indicate Diamond Sharks along with falcon merchants selling IS resources, something I address later.
Interesting to note that resources constrained military manufacturing for the Clans, which can be seen in examples like the Smoke Jaguar adoption of Protomechs. It could also explain why Jade Falcon abandoned the protomech project, as they enjoyed unparalled access to resources that the home clans do not enjoy.
Another thing to note is that Clan Jade Falcon and Ghost Bear has excess elemental manufacturing capabilities, but Clan Wolf does not or were unable to participate in the market to Diamond Shark. Alternatively, Clan Wolf has the mercantile fleet to participate in such trades directly and does not require the intervention of Clan Diamond Shark to obtain such weapons.
